General Description

RTS Wireless BTR-80N UHF Synthesized Wireless Intercom system offers reliable, high-performance, high-fidelity full-duplex communications delivered with minimum spectrum usage.

The BTN-80N system includes the BTR-80N frequency agile base station and up to four (4) TR-80N or TR-82N frequency agile beltpacks operating in full-duplex communications. An almost unlimited number of beltpacks may be used with a base station if the beltpacks are in Push-To TX mode (half-duplex).

The BTR-80N system incorporates two (2) audio channel operation, permitting the beltpack operator to choose between two (2) separate audio channels of communication, with the base station tracking the beltpack selection. This allows the user the flexibility to create a party line and a private line within the same beltpack.

The BTR-80N system is perfectly suited for standalone operation and can also interface with other RTS wired intercom systems. In addition to the external intercom systems interfaces, the system provides connections for auxiliary balanced audio input and output, as well as wireless talk-around (WTA) and stage announce (SA) features.

The BTR-80N system has been designed for reliable, efficient operation. Operating in the 482 to 722MHz range, the units perform reliably at line-of-sight distances of 1000 feet. With available antenna systems from RTS, the effective operating range can be extended. The high-efficiency beltpacks provide between 8 and 11 hours of uninterrupted operation using NiMH rechargeable battery packs.

System Features

• Frequency-agile base station and beltpacks. No external computer/device required to select frequencies.
• Backlit base-station LCD allows the user to easily monitor the beltpack's status and change base station frequencies.
• Squelch adjust on the BTR-80N, TR-80N, and TR-82N beltpacks.
• Beltpack's battery level displayed on the base station and in beltpack's menus.
• ClearScan function on base station and beltpack to automatically find the best channels on which to operate.
• Full-duplex (simultaneous talk and listen) or Push-to-Tx (half duplex) operation.
• Compatible with Audiocom (Telex), RTS TW and Clear-Com wired intercoms.
• Two (2) independent channels of intercom audio with the ability to operate party line and RTS matrix on the same intercom channel at the same time.
• WTA (Wireless Talk-Around) beltpack control. This feature allows beltpacks to talk to each other, but their audio is lifted from any wired system connected to the base station.
• SA (Stage Announce) beltpack control. Allows the user to direct their audio to a jack on the back of the base for P.A. systems or other external audio systems.
• Relay contact closure on the base when the SA button is pressed.
• TR-82N features two (2) audio channel binaural operation in either stereo or mono mode.
• TR-82N has a 1/8-inch (3.5mm) jack for auxiliary input from another audio source, such as an IFB, iPod, or other similar device.
• Beltpack units contained in a weather and shock resistant die cast magnesium case.
• Convenient IEC power connector on the base station so the unit can plug directly to outlets. No in-line or wall plug power supply.
• Dark mode configurable on TR-80N and TR-82N beltpacks. This shuts down all LEDs.

Antenna Connection

The base station is supplied with two (2) antennas. One 1/2-wave antenna for transmit and one 1/2-wave for receive. The antennas have TNC male connectors.

The frequency range of the antennas should match the receiver and transmitter of the base station. Match the color code on the antenna with the color code on the base station.

Attach the transmit 1/2-wave antenna to the antenna input receptacle labeled Transmit on the right side of the rear panel. The antenna should be vertically aligned.

FIGURE 12. Vertically Polarized Antennas

Distance between Antennas

The distance between the base station's receive and transmit antennas is not adjustable when the antennas are connected directly on the back of the unit.

The antennas can be remotely mounted for a better signal path. An RTS coax assembly with remote antennas may be required. See “Accessory” section for ordering information.

NOTE: If your base station is to be located in a shielded rack mount enclosure or other poor RF locations, you must remotely mount the 1/2-wave antennas with coax assemblies. See “Accessories and Replacement Parts, for remote mounting hardware.

Antenna Placement

Proper antenna placement probably has the most effect on your RTS Wireless Intercom System's overall performance. The following suggestions result in optimum performance.

Proper placement of the beltpack can be critical. The antennas should be in the open. Bending the antennas up and placing the beltpack in a pocket, etc., reduces the system's distance. The unit should be worn on the belt with both antennas vertical for best operating range and performance.

FIGURE 13. Proper Dressing of the Antenna

Keep the distance between the base station and the beltpacks as short as possible. The greater the distance, the weaker the signal. Make sure the “signal paths” between the base station and beltpacks are unobstructed. You should be able to visibly locate the base station antennas at all times for best performance.

FIGURE 14. Distance Between Base Station and Beltpack

FIGURE 15. Keeping Site Clear to Antenna

Attempting to operate the wireless intercom system through or around walls, ceilings, metal objects, etc. reduces system range and performance.

Diagram showing wireless signal transmission between a network device and a sensor device (no text or symbols present)

FIGURE 16. Operating System Near Obstructions

IMPORTANT: DO NOT mount the base station 1/2-wave antennas on or next to: metal, such as beams; walls with metal studs; or equipment racks, etc. This also applies to antennas assembled directly to the Base Station. Mounting antennas near metal detunes the antennas, which can result in noise or loss of RF signal at the Base Station. See Figure 17.

1. Placing the BTR on top of a shelf or equipment rack unobstructed without remoting the antennas is OK.

2. Placing BTRs in a shelf or equipment rack and using remote antennas is OK.

3. Placing BTRs in a shelf or equipment rack with the antennas mounted on the back of the BTR or the side of the rack is BAD.

Improving Reception and Increasing Range

Keeping the distance from the base station and beltpack as short and unobstructed as possible produces the most reliable antenna performance.

The base station is supplied with two (2) antennas. This provides satisfactory system performance in most applications. System range can be enhanced by remotely mounting the 1/2-wave antennas. The 1/2-wave antennas are ground plane independent, so a ground plane is not required for good performance.

BTR-80N

Operation

This section discusses the operation and features of the BTR-80N base station, opening with base operation and quick system setup. It then discusses basic interfacing and setup of a base station, then ends with the connection of multiple base stations and discussion of the links between them.

Basic Operational Description

The BTR-80N narrow band wireless intercom system offers the most comprehensive, user-friendly, and versatile set of features available in wireless intercom systems anywhere in the world.

The base station accommodates up to four (4) full-duplex TR-80N or TR-82N beltpacks, and can be used with an unlimited number of beltpacks in push-to-TX (half-duplex) operation. In push-to-TX mode, the unit provides a First On Latch Out feature which allows only one beltpack transmitter to be active at a time when multiple users are on a single base receive channel.

The base station, via the beltpacks or it's local headset, allows communications with other wireless or wired users. The 2-wire and 4-wire intercoms may even be used at the same time. The wired audio interfaces to the base are:

• 2-Wire (Telex, RTS, Clear-Com) - 2 intercom channels
• 4-Wire - 2 audio channels
• Auxiliary (both input and output)
• SA (Stage Announce) (output)
- WTA (Wireless Talk-Around)/ 2 channels of private 2-wire intercom among TR-80N and TR-82N beltpacks
- Local base station headset

The base station also features:

• A relay closure activated when the SA button is pressed at any beltpack
• Four (4) easily accessible portable connect buttons on the front panel. Use the buttons to turn off the audio from any of the four (4) base receivers while at the same time killing the talk/transmitter at the associated beltpack
• 36 engineering selected, intermodulation avoiding, factory-defined groups
• The ability for users to enter frequencies of their own via 12 user-defined groups

System Quick Start

The following is a list to quickly get a base station and beltpacks operating.

1. Unpack the base.
2. Connect the power cord and antennas.
3. Connect the base to audio interfaces, such as: 2-wire, 4-wire, SA, Auxiliary, or local headset.
4. Press and hold MENU while powering up the base station.

5. When the base station displays FACTORY SETUP, release MENU.

6. Unpack the beltpacks.

7. Press MENU while powering up the beltpack(s).

8. Using the UP and DOWN arrow buttons, change the beltpack channel to an unoccupied receive channel on the base station.

9. Press SET twice to set channel and group. The base should now display the audio channel of the beltpack and a battery symbol appears shortly.

10. Plug a headset into each beltpack.

11. Adjust the microphone gain in the software menu so the overmodulation light flashes only on some of the words at normal speech levels.

FIGURE 18. BTR-80N Rear View

Transmit and Receive Antennas

The TNC transmit jack and receiver jack are both labeled on the rear of the unit. The base station comes with two (2) 1/2-wave antennas. Always match the color dot on the rear panel of the base station with the colored band on the antenna.

2-Wire Intercom Ports

The base station has the ability to interface with two (2) 2-wire external audio intercom systems. These XLR jacks are designated intercom 1 and 2 on the rear panel.

They accept Telex, RTS, and Clear-Com types of intercom systems. The pinouts of these standard types of intercom are shown in Figure 19.

The base station does not require wet intercom lines for operation. Wet intercom lines are those with D.C. voltages on them for powering 2-wire devices. The base loops through wet intercom lines with currents up to two (2) Amps.

WARNING: Do not loop through more than two (2) Amps of current. Damage to the base station may result.

FIGURE 19. Pinouts of RTS, Telex, and Clear-Com Intercoms

FIGURE 20. Loop-through of two base stations connected with Telex/Audiocom or Clear-Com Intercoms

If multiple base stations are connected via 2 -wire intercom and no 2-wire power supply is involved to terminate the 2-wire, then termination plugs for the type of 2-wire system used must be at one end of each intercom line.

Since RTS-TW carries both channels of audio on one (1) cable, the four (4) intercom XLR connectors are connected in parallel when RTS is selected. Thus any one (1) of the four (4) intercom XLRs may be used for RTS input. Looping through of the audio, shown in Figure 21, may also be accomplished via any of the rear panel XLRs when in FTS mode. For a description of how to set up the 2-wire ports, refer to Intercom Settings in this section. The 2-wire intercom may be used at the same time as the 4-wire intercom.

FIGURE 21. Loop-through of two base stations connected with RTS Intercoms

FIGURE 22. BTR-80N Rear View

4-Wire Intercom Ports

The BTR-80N can connect to two (2) 4-wire audio intercom systems. These 6-pin modular jacks (RJ-11) are designated 4-wire under intercom 1 and 2 titles on the rear panel. (See Figure 22). The jack's pinout is shown in Figure 23.

FIGURE 23. Pinout of the 4-Wire Jack

The 4-wire intercom may be used at the same time as the 2-wire intercom.

Auxiliary Input/Output

The auxiliary input jack is a combination jack. It accepts either a 3-pin XLR or a 1/4" (6.3mm) plug. The expected input is a balanced line level input. Shown in Figure 24, the XLR plug and 1/4" plug are wired in parallel

FIGURE 24. Auxiliary Input XLR and 6.3mm Jack Pinouts

The auxiliary output jack is a 3-pin XLR jack. It produces a line level balanced output. Please refer to Figure 25.

FIGURE 25. Pinout of the Auxiliary Output Jack

The auxiliary input/output can be set to local, global, or off. (See the Aux Settings menu in the base). The output level is configured in the software.

• Local Aux Input - The input audio is only heard at the base station's local headset and beltpacks.
• Local Aux Output - The output audio is only heard at the base station's local headset and beltpacks.
• Global Aux Input - The input audio is heard at the base station's local headset and beltpacks and is placed on the 2-wire/4-wire intercom.
• Global Aux Output - The output audio is heard at the base station's local headset and beltpacks and is placed on the 2-wire/4-wire intercom.
  • Off - the auxiliary input and output is off.

FIGURE 26. BTR-80N Rear View

Base Station Link

This pair of RJ-45 jacks allow the passage of WTA, WTA termination control voltage, and CAN bus data between multiple base stations. Up to eight (8) base stations may be connected with the base station link. If just using WTA between bases, up to 16 base stations can be connected together. The pinout of the IN jack and OUT jack may be seen in Figure 27 and Figure 28

FIGURE 27. Base Station Link IN RJ-45 Jack Pinout

FIGURE 28. Base Station Link OUT RJ-45 Jack Pinout

Stage Announce (SA)/Relay

The Stage Announce 3-pin XLR connector (see Figure 26) is where audio exits the base when a beltpack user presses the SA button. The pinout of the plug connector is shown in Figure 29.

FIGURE 29. Stage Announce Pinouts

The stage announce output is balanced audio at line level. The output level is configured in the software.

A relay contact closure also activates when a beltpack user presses the SA button. The contacts are normally open (N.O.). The relay schematic is shown in Figure 30. The rating of the relay is 1 Amp at 24 volts AC or DC maximum.

FIGURE 32. BTR-80N Base Station Link Jack and Program Jack

Base Station Link Jack

WTA 1 and WTA 2 in the BTR-80N are two (2) independent 2-wire intercom channels. Up to 16 base stations may be connected together to share WTA audio. Do not confuse WTA audio with CAN bus data, as only eight (8) bases may be connected to share CAN bus data. Not only does the WTA Link cable pass both channels of WTA audio, it passes a logic level so the 1st base station in the chain is the only one providing a termination of the WTA intercom channels. Care must be taken to connect cables between base stations from the OUT of base one (1) to the IN of base two (2) and so forth. If the WTA link cable is passed from OUT to OUT or IN to IN, the WTA audio may terminate in multiple places and cause the WTA audio level to be greatly reduced.

The base station link jacks can interface with other base stations via two (2) different types of cables:

- Base Link Cable (BLC)

- Straight through cable. Passes CAN data, WTA audio, and WTA termination signal.

• CAN Bus Termination Cable (CTC)

- Passes WTA audio and WTA termination signal, but does not pass CAN data. Acts as a termination of the CAN networks on either side of it.

Detailed information on the pinout and operation of these cables can be found in "Connection of Multiple Base Stations with the Link Cables" on page 40.

Program Jack

This jack is only used for updating the internal software of the base station. It is typically used only by the manufacturer and service centers.

FIGURE 33. Multiple Base Stations Connected via 2-Wire Cables Sharing WTA Audio

FIGURE 34. BTR-80N - Front Panel

Powering the Base Station

The base station may be powered two (2) different ways:

• Line power at the IEC receptacle. Accepts 100–240VAC, 1A max., 50 or 60Hz.
• 12–15VDC Power. Accepts a 5.5mm by 2.5mm screw on plug. Source must supply at least 3.5 Amps.

To power on the base station, do the following:

Press the POWER button located on the far left of the base station front panel.

To power off the base station, do the following:

Press and hold the POWER button.

Both line power and DC power can connect to the base station at the same time. If AC line voltage drops, the base draws power from the DC input automatically. When the AC line power is restored, the base automatically switches back to AC power. There is no interruption in the base operation during these transitions.

CAUTION: Do not power up a base station within three (3) seconds of the unit being turned off. Voltages within the unit need time to drop below a threshold. If powered up within the above time, the unit may boot as the wrong frequency band.

WARNING: Even with the unit powered down via the power switch, some circuits within the base remain energized. To completely remove power to the unit, disconnect the power cord.

Connection of Multiple Base Stations with the Link Cables

This section discusses various configurations of multiple base stations using link cables. Multiple base stations may be connected via standard 2-wire and 4-wire intercoms without additional link cables between them. They still transmit and receive intercom 1 and intercom 2 audio normally from the beltpacks.

FIGURE 56. Multiple base stations with only 2-wire intercom channels 1 and 2 connected between them

However, by connecting multiple bases together via link cables, in addition to any 2-wire or 4-wire audio connections in use, the feature set of a single base becomes available to the whole system. This feature set also includes base stations that have their transmitters off in order to conserve RF spectrum.

- Beltpack Talk shutdown via the base front panel extended to base stations with their TXs off (when beltpacks are in push-to-talk mode).

These features are:

• (WTA) Wireless talk-around channels 1 and 2 shared between base stations.
• First-On-Latch-Out of beltpacks extended to base stations with their TXs off (when beltpacks are in push-to-transmit mode).
• Automatic beltpack TX power control extended to base station with their TXs off.
• Automatic beltpack user ID assignment extending to base stations with their TXs off.
• Beltpack TX and Talk shutdown via the base front panel extended to base stations with their TXs off (when beltpacks are in push-to-transmit mode).

Before presenting the configurations, we believe an explanation of RF data links plus master and servant base stations helps in understanding the multiple base arrangements.

Over-the-Air Data Links

There are two (2) RF data communication links within a BTR-80N system.

- Beltpack-to-base conveys:

• Current button(s) selected
• Battery level
• Beltpack ID set confirmation

- Base-to-beltpack conveys

• Beltpack User ID
• Beltpack TX power level
• Beltpack TX and/or Talk Shutdown
• First-On-Latch-Out

Base-to-Beltpacks Data Link (2 Links, 1 for each base transmitter, but same data on both.)

Beltpack-to-Base Data Link (One for Each Beltpack)

FIGURE 57. Base-To-Beltpack and Beltpack-To-Base RF Data Links

These two (2) data paths are intact when there is only one (1) base communicating to beltpacks. They are also intact when many base stations on different TX and RX frequencies are communicating to their beltpacks.

However, in a system with one (1) or more base stations with their transmitters off, the base-to-beltpack data link is lost for those bcltpacks

A wired data link is needed to communicate the base-to-beltpack information from the base stations with their transmitters off to the base with its transmitters on.

FIGURE 58. Three (3) base stations connected via 2-wire intercom only Two (2) bases have their transmitter off; one has its transmitters on

Master and Servant Base Stations

A master base station is one that the user has set its base number to 01(Master) and has its transmitters on. A master base conveys base-to-beltpack data to its beltpacks and via a base station link cable, relays the base-to-beltpack data from

base stations that have their base transmitters off. A master may support up to seven (7) additional base stations with their transmitters off.

IMPORTANT: There can be only one (1) master base station in a network of base stations.

A master base automatically sets a 09 (default) base to a unique 02 to 08 servant number. If a base is already a servant the master leaves it at that same number.

FIGURE 59. Status screen of a master designated base station

NOTE: Any time base stations are changed to be a master base station, it must be power cycled for the change to take affect.

A servant base station is one that has its transmitters off and is connected to a master base. Since servant base stations have their transmitters off, base-to-beltpack information can only get to beltpacks via link cables connected to a master base station. There can be up to seven (7) servants working with one (1) master.

FIGURE 60. Status Screen of the Servant Base Station

FIGURE 61. How to get to the master/servant selection screen

From the factory, base station are set to base number 09. This is an unassigned base. The base can be left as 09 if not in a linked system. It works as normal with all features.

If the unassigned base is connected to a master base station, the master automatically assign a valid, unique, servant ID to it the first time the networked system is powered-up.

The master base must always power-up after the servant bases in order to detect servant units to control. If all the units are on a common power strip, this is controlled by a built in delay on master base station. The master base station always boots slower than servant units.

CAN bus

A CAN (Controlled Area Network) bus is the data protocol used over the BTR-80N's base station link cable. This balanced protocol is a robust standard used the world over in high noise, extreme environments. It requires the use of 120 Ohm terminators at the beginning and end of a CAN bus network.

FIGURE 62. CAN Bus 120 Ohm termination (CAN-T) and base pin functions. Part Number: PRD000223002 (not supplied)

FIGURE 63. A base link cable connected system with terminators on both ends

Base Station Link Configurations

Multiple base station networks may be connected in different ways. Using the rear panel base station link jacks, a user has three (3) different connection options.

These options are:

• WTA (Wireless Talk-Around) Audio Only

• Bases connected via 2-wire and/or 4-wire audio links
• All bases share WTA audio
• They do NOT share CAN bus data

• WTA and a SINGLE CAN Bus Network

• Bases connected via 2-wire and/or 4-wire audio links
• All bases share WTA audio
• All bases are ON A SINGLE CAN BUS NETWORK

• WTA and Several CAN Bus Networks

• Bases connected via 2-wire and/or 4-wire audio links
• All bases share WTA audio
• There is MORE THAN ONE CAN BUS NETWORK

FIGURE 64. Base station link input and output jacks on the rear of the BTR-80N

Wireless Talk-Around Audio Only

These base stations are connected to share WTA channel 1 and WTA channel 2 audio but do not share the CAN bus data.

Link Overview

WTA 1 and WTA 2 in the BTR-80N arc two (2) independent 2-wire intercom channels. The WTA intercom channels are very similar to AudioCom types of intercom channels except they are dry and are meant to only pass audio between BTR-80N base stations.

Up to 16 base stations may be connected together with base link cables (BLC) depending on cable length and conductor size. The BLC passes both channels of WTA audio. It also passes a logic level so the 1st base station in the chain is the only one that provides a termination of the WTA intercom channels. This pin is labeled "TERM CONT" on the RJ-45 plug pinouts in this section.

Care must be taken to connect cables between base stations from the OUT of base one (1) to the IN of base two (2) and so forth, unit to unit.

If the WTA link cable passes from OUT to OUT or IN to IN, the WTA audio terminates in multiple places and causes the WTA audio levels to be greatly reduced/distorted.

FIGURE 65. BLC (Base Link Cable) and pin functions. Part Number PRD000223000 (Not Supplied)

If base stations are farther apart than the 12" (30.48cm) BLC, then 568-A or 568-B Ethernet cables of CAT-5E or above may be used to connect base stations up to 300 feet apart. These Ethernet cables contain four (4) twisted pairs like the BLC cable.

FIGURE 66. Multiple base stations connected via 2-wire audio cable and WTA through via BLCs

Do not set base stations to the base number 01 (Master), because CAN bus is connected to the other base stations with a BLC, as seen in Figure 66. If there are no masters on the CAN bus system, there is no activity on the CAN bus line and no need for terminations.

IMPORTANT: The master base must always power-up after the servant bases in order to detect servant units to control. If all units are on a common power strip, this is controlled by a built in delay on the master base station. The master base station always boots slower than servant units.

Setup

1. Connect the power cords to the base stations.

IMPORTANT: Do not power up the base stations.

1. Connect the transmit and receive antennas to the base stations.

NOTE: The color dots on the rear of the base should match the color rings of the antennas.

1. Connect the main intercom audio channel(s) to the base stations.

NOTE: This may be 2-wire intercom. This could also be 4-wire intercom via a matrix type wired system.

1. Connect the Base Link Cable between base stations.

NOTE: Verify the OUT of the first base station connects to the IN of second base station and follow the same connection pattern forward.

1. Power-up all the base stations.

NOTE: The base stations should be set to all unique transmit and receive frequencies.

1. Setup via the BTR-80N software menus the intercom, local headset, auxiliary, stage announce, etc. as detailed in BTR-80N Operation.

NOTE: All the base station numbers should be left as 09 (default).

1. Turn on only one (1) beltpack.

NOTE: Try to keep the beltpack at least 6' (2 meters) away from the base's antennas.

1. Set the beltpack on the appropriate group and channel for its base station. As each beltpack is set to its group and channel, an hourglass symbol appears on the base display in the location normally occupied by the battery symbol. A beltpack is assigned an ID number by the base in this time.

Finally, a normal battery symbol is displayed, indicated the beltpack has been assigned its ID number.

1. Once the beltpack has an ID number, turn the beltpack off.
2. Turn on the next beltpack.
3. Repeat steps 8-9 for each additional beltpack.
4. Power up the beltpacks.

WTA and a SINGLE CAN Bus Network

These base stations connect via 2-wire and/or 4-wire audio links and also by the Base Link Cable (BLC). The BLC cable passes WTA audio and CAN bus data information. The CAN bus connected base stations form a Network.

Link Overview

There are two (2) RF data communication links with a BTR-80N system. The beltpack-to-base links convey information such as current button(s) selected, battery level, etc. The base-to-beltpack links convey beltpack user ID, beltpack TX shutdown, beltpack talk shutdown, and other information.

The two (2) paths are intact when there is only one (1) base communicating to beltpacks and when many base stations on different TX and RX frequencies communicate to the beltpacks. However, when one (1) or more base stations with their transmitters off are connected to a base station with its transmitters on, the base-to-beltpack data link is lost for those beltpacks.

Care must be taken to connect cables between base stations from the Out of base one (1) to the IN of base two (2) and so forth. If the WTA link cable is passed from OUT to OUT or IN to IN, the WTA audio terminates in multiple places and causes the WTA levels to be greatly reduced/distorted.

IMPORTANT: The master base must always power-up after the servant bases in order to detect servant units to control. If all units are on a common power strip, this is controlled by a built in delay on the master base station. The master base station always boots slower than servant units.

A beltpack is assigned an ID number by the base in this time. Finally, a normal battery symbol displays, indicating the beltpack has been assigned its ID number.

2. Once the beltpack has an ID number, turn the beltpack off.

3. Turn on the next beltpack.

4. Repeat steps 22-23 for each additional beltpack.

5. Power up the beltpacks.

WTA and Several CAN Bus Networks

These base stations may be connected via 2-wire and/or 4-wire audio links. They are also connected together via the Base Link Cable (BLC) and a new cable called the CAN Bus Termination Cable (CTC).

FIGURE 68. CAN Bus Termination Cable (CTC). Part number: PRD000223001 (Not Supplied)

Link Overview

Multiple masters on the same CAN bus are not allowed. The two different cables solve this issue. The BLC passes WTA audio and CAN bus data information. The CTC passes WTA audio and also functions to terminate the CAN network on either side of it. This allows many separate CAN networks to share the same two (2) WTA audio channels.

Care must be taken to connect cables between base stations from the OUT of base one (1) to the IN of base two (2) and so forth, unit to unit. If the WTA link cable passes from OUT to OUT or IN to IN, the WTA link cable terminates in multiple places and cause the WTA audio levels to be greatly reduced/distorted.

The master base must always power-up after the servant bases in order to detect servant units to control. If all units are on a common power strip, this is controlled by a built in delay in the master base station. The master base station always boots slower than servant units.

Setup

Setup is the same as the previous “WTA and a SINGLE CAN Bus Network” section, with the exception of a CTC cable between the two CAN networks.

1. Connect the power cords to the base stations.

IMPORTANT: Do not power up the base stations.

1. Connect the transmit and receive antennas to the base stations.

NOTE: The color dots on the rear of the base should match the color rings of the antennas.

1. Connect the main intercom audio channel(s) to the base stations.

NOTE:

• This may be 2-wire intercom. This could also be 4-wire intercom via a matrix type wired system.

• If using a party line to connect audio channels, the party line needs to be terminated by a connected PSU or a load XLR plug (P.N. TP-3 or TP-3R). See Figure 69.

• Connect the (BLC) Base Link Cable between base stations within a CAN network.

NOTE: Verify the OUT of the first base station connects to the IN of second base station and follow the same connection pattern forward.

1. Connect the CAN Bus Termination Cable (CTC) BETWEEN the CAN networks.
   NOTE: Remember to connect from the OUT of the base station to the IN of the next base station.
2. Place CAN bus termination plugs (CAN-T) at the beginning and end of the networked base stations.
3. Power-up all base stations.
4. Set all base stations to factory defaults via a four-button reset; MENU + SET + UP + DOWN.
5. Power-down all the base stations.
6. For the first network of base stations, power-up the first servant base station.

Transmit Power

The Transmit Power screen displays the current setting of the beltpack transmitter's output power level. There are four (4) settings.

Transmit Power Settings

Auto(Default)	The beltpack's transmitter adjusts its output level according to information sent to the beltpack from the base station. It adjusts between tow (2) levels: 5mW or 50 mW.
5 The beltpack transmits at 5 mW
50 The transmitter is at 50 mW
100 The transmitter is at 100 mW

When the unit is set to auto, base station information tells the beltpack the appropriate power settings to use based upon the received signal strength level at the base station. By reducing the transmit power when possible, the battery life of the beltpack can be slightly extended and intermodulation products can be reduced.

To change the transmit power setting, do the following:

1. Push SET at the transmit power screen.
2. Using the UP/DOWN arrow buttons, select the power setting.
3. Push SET to place the unit at the indicated setting.

ClearScan™

ClearScan™ helps you find clear RF frequencies in your area. The beltpack's receiver scans all the factory-defined groups and any set user-defined groups. The result is a list of beltpack receive groups, clear of interference.

To enter ClearScan ^TM , do the following:

1. Press and hold MENU + SET for two (2) seconds to start ClearScan ^TM . The beltpack display changes to ClrScn and the GP icon flashes. After about 12 seconds, the beltpack displays the first clear group. The group number flashes.
2. Using the UP/DOWN arrow buttons, display the clear groups.
3. Press SET to select a group.
4. Press MENU to bail out without selecting a group.

Clear groups are displayed first. They are in group order. You can scroll down through groups using the DOWN button. The left-half of the screen gives you an indication of interference levels as you scroll through the groups.

User-defined groups without a defined frequency for one of the receive channels display a u to indicate undefined.

The degree of interference found for R1 and R2 displays on the far-right two (2) positions on the screen.

Interference Level Right Half of LCD Display
None Blank
Weak Single Bar
Moderate Double Bar
Strong Triple Bar

Lock Out

Lock Out allows the user to lock the top panel and menu options. The top panel buttons still work, but the TALK button options cannot be changed. Likewise, values on the LCD screen in the beltpack can be viewed but not changed.

To enable/disable Lock Out, do the following:

1. Press and hold the UP and DOWN buttons for two (2) seconds.
   The words Loc on appear on the screen when lock out is active.
2. Press and hold the UP and DOWN buttons for two (2) seconds again to disable lock out.
   The words Loc off appear.

First Use Default

First Use Default sets the beltpack to Group 1A, channel 1 and leaves any user-programmed groups in memory. It sets units to factory-defined menu settings. It also sets the TALK buttons to their default modes.

To activate the 1st Use Default, do the following:

Press and hold MENU while powering-up the beltpack.

Factory Reset

Factory Reset sets the beltpack to Group 1A, channel 1 and ERASES any user-defined groups in memory. It sets a unit to factory settings. It also sets the TALK buttons to their default modes.

To activate factory reset, do the following:

Press and hold MENU + SET + UP + DOWN for two (2) seconds.

RF Monitor Screen

The RF Monitor Screen displays beltpack RF status.

To display the beltpack RF status, do the following:

1. Press and hold MENU for two (2) seconds to display beltpack RF status.

2. If the channel button is set to 1, then signal strength displays for R1 frequency.

3. If the channel button is set to 2, then signal strength displays for R2 frequency.

TX Power Signal Strength

Lo = 5mW 0 = NO

hi = 50mW 1 = Very Weak

Hi = 100 mW 2 = Weak

3= Moderate

4= Strong

5= Very Strong

1. Press MENU again to exit RF Monitor Screen.

Setting Beltpack ID

Several functions require the beltpack to know which base and channel it is associated with.

1. Auto Power Setting: The beltpack reduces its TX power when close to the base. Beltpack transmit power must be set to Auto.
2. Portable Station Deselect: The base can disable the TALK button of a beltpack. This shuts off the mic in PTT mode and turns off the transmitter in PT TR mode.
3. First-On-Latch-Out: This locks a base receive channel so only one beltpack can transmit on the frequency at a time. A beltpack user attempting to talk on top of another beltpack on the same frequency hears a double beep in their headset.

A beltpack tries to establish its ID automatically when its group/channel changes. The base must be on for this to work.

To check or set beltpack ID manually, do the following:

1. Press and hold UP for two (2) seconds. The LCD displays ID Base# - Receiver#.

For example: ID 1-3 means Base 1, Receiver 3.

If the LCD displays ID--- or does not match the base and receiver, the beltpack is assigned to, Auto Power, Portable Station Deselect, and First-On-Latch Out will not work correctly.

1. If the beltpack ID is correct, press MENU to exit.
2. If the beltpack ID is not correct, press SET. The ID numbers flash.
3. Using the UP/DOWN buttons, select a new ID.
4. Press SET to apply the new ID.

Bases with transmitters enabled are always base #1. A second base using the first base transmitters instead of its own, and properly connected to the first base through CAN bus link cables becomes base #2, etc.

Frequency Bands

The BTR-80N system operates over the following frequency ranges:

North America

• Base TX: 482-608 MHz
• Base RX: 572-608 MHz, US 3 Band: 653-663 MHz

Europe

• Base TX: 482-608 MHz
• Base RX: 572-608, 614-722 MHz

The bands, US TV channels, and frequencies are shown in Figure 81. Most bands are 18 MHz wide.

Bands F to C are always base transmit bands (beltpack receive bands). Bands 1-6 are always base receive bands (beltpack transmit bands). Bands D and E can be both a base transmit or receive band, depending on the unit ordered. Thus an A2 base station is comprised of an A band transmitter and a two (2) band receiver.

Band Pairing for Systems

All band pairs cannot be made into a system. Table 3 show the available band pairings.

Base TX Bands Base RX Bands
F	D, E, 1, 2, 3, 4, 5, 6
H	E, 1, 2, 3, 4, 5, 6
A	1, 2, 3, 4, 5, 6
B	2, 3, 4, 5, 6
C	3, 4, 5, 6
D	4, 5, 6
E	5, 6

TABLE 3. Available band pairings

In Table 3, it can be seen that a C base station transmit band can be paired with 3, 4, 5, or 6 receive bands. However, a C2 unit cannot be made. This is because a certain amount of frequency separation between transmit nad receive bands is required for good transmit and receive operation. If they are too close the RF performance of the system is reduced.

Frequency Plan

There are 48 groups in a BTR-80N system. The 48 groups are divided up into 36 factory-defined groups and 12 user-defined groups. A group referenced to a base station is comprised of two TX channels and up to 12 RX channels.

User-defined groups are blank initially and allow the user to enter their own frequencies.

Factory-defined groups are composed of frequencies that cannot be modified by the user. The 36 groups are composed of the following:

Nine (9) Triplet Groups

- Groups 1a to 9c

Nine (9) Single Groups

- Groups 10-18

The factory groups are organized in different ways to provide flexibility to the user on selecting frequencies. A groups is composed of intermodulation free frequencies. The triplet groups may be used together for up to three (3) systems that are intermodulation coordinated. For example, three intermodulation coordinated systems may be set up by using the following groups and channels:

• System A = Group 1a, channels: 1, 2, 3, 4
• System B = Groups 1b, channels: 5, 6, 7, 8
• System C = Group 1c, channels: 9, 10, 11, 12

A group also contains frequencies within different combinations of the TV channels. The user can select a group clear of broadcast Tv channels in the area by selecting a group(s) not using those channels.

Figure 82 indicates how the factory-defined groups used the three (3) TV channels for TX and three (3) TV channels for receive. These plans are based upon US broadcast TV channels. A darkened TV channel indicates the group has frequencies in the channel. The white TV channel indicates the group has no frequencies in the channel. For example, Group 1A uses at least one (1) frequency from each of the three (3) TV channels for RX and only the 1st TV channel for TX. However, group 18 uses only the 3rd TV channel for TX and RX.

Three band base stations and beltpacks used in the US have a reduced channel map offering due to regulatory changes that reduce the size of the three bands.

For more information, see “Three (3) Band Base Stations” on page 86.

Troubleshooting

PROBLEM SOLUTION
DISTORTION - System's audio quality seems distorted at medium to high input levels	Reduce microphone gain by adjusting microphone gain control in software.
HISS - System seems to produce a hiss which is undesirable.	Check the gain setting on all beltpacks and the base. They may be too low or too high. Check to make sure you are still well within range of the base station.
LOW OUTPUT - System produces a low output level.	Check the gain setting on both the beltpacks and the base. They may be too low.
FEEDBACK - Moving around are of use produces squcal or howl in various locations using the ext. speakers.	Reduce the gain settings on both the beltpacks and the base. They may be too high. If in 2-wire mode, the intercom channel you are on may be unloaded.
DROPUOUTS - When moving around the area of use there seem to be locations where the signal swooshes or completely disappears.	Make sure both antennas on the base and beltpack are connected and follow the location suggestions. Change the location of the base unit and antennas or avoid the bad areas with the remote beltpacks.
INTERFERENCE - System picks up signals other than wireless intercoms.	Make sure the Telex beltpack(s) are on. If there are any unused receivers at the base, turn the audio off from those receivers by deselecting the appropriate Portable Station Connect button.If problems persist with the beltpack on, you will probably need to change the group. Make sure the base and beltpack match after any Group/Channel change.
NO AUDIO - from base of beltpack headsets.	Check transmitter setting on base and beltpack. Check talk LED to ensure it is on. Make sure beltpack batteries are OK.
BASE and BELTPACK'S Frequencies Don't Match - In the display frequencies screen of the base and the menu of the beltpack the frequencies don't match.	Ensure the units are on the correct Group and Channels. If three (3) band base and beltpack units and in the US, make sure you have switched the base station to the US channel map. See “Three (3) Band Base Stations” on page 86.

IMPORTANT: Reread the sections of this manual to make sure you completed system set-up properly. If you are unable to solve the problem, contact the dealer from whom you purchased the system for assistance

Battery Information

Improper battery selection, use, installation, and care are the cause of numerous wireless systems failures.

Alkaline Batteries: Alkaline batteries such as Eveready's ENERGIZER and ENERGIZER INDUSTRIAL provide the most reliable operation in wireless transceivers.

The use of low cost carbon-zinc batteries is NOT recommended.

Nickel-Metal Hydride Batteries: These batteries can save you money in the long run, as they can be recharged. Typical battery life is a little less than the length of time alkaline batteries last.

Battery Warnings

• Do not place alkaline battery packs in any battery charger. Severe charger and battery pack damage may occur!
• Batteries that have been dropped, or otherwise damaged, should not be used and should be discarded properly. Dropping batteries can crack the internal casing causing leakage or rupture resulting in personal injury or property damage!
• Insert batteries properly, with the plus (+) and minus (-) terminals aligned correctly!
• Do not mix old and new batteries, batteries of different types, or batteries of different brands. This can cause leakage or rupture, resulting in personal injury or property damage!
• Immediately remove exhausted batteries from the battery pack and dispose of properly.
• Replace all used batteries in your device at the same time.
• Do not put batteries or battery-powered devices in very warm places. Extreme temperatures reduce battery performance and may also lead to leakage.
• Use only high quality AA sized alkaline batteries in the battery packs.
• When not in use, disconnect battery pack, remove and store batteries in a cool, dry place at normal room temperature until ready to use.
• Keep battery contact surfaces clean by gently rubbing with a clean pencil craser or cloth.

Battery Life

TR-80N

Alkaline, 11-13 hours typical

Nickel-Metal Hybrid, 10-12 hours typical

TR-82N

Alkaline, 8-10 hours typical

Nickel-Metal Hybrid, 7-9 hours typical

Energizer® is a registered trademark of Union Carbide

Corporation

Cold Temperatures and Batteries

The battery life times listed in this section are at room temperature. Alkaline and Nickel-Metal Hydride battery service hours fall off significantly at low temperature due to battery chemistry. Alkaline batteries typically have less than half their room temperature service life if used at freezing 32^ F ( 0^ C). If you use Alkaline and Nickel-Metal Hybrid batteries at low temperatures, you need to change them more often.

Another solution is using Lithium AA cells if beltpacks are to be used in very cold temperatures. Lithium batteries, like the Energizer ultimate Lithium AA cells, are excellent batteries for cold temperatures. At 15^ F ( -9^ C), Lithium AA cells will last about seven (7) times longer than Alkaline batteries. This equates to two (2) hours for Alkaline vs. 14 hours for Lithium. However, the trade off is Lithium batteries cost more and are less environmentally-friendly than Alkaline batteries.

Three (3) Band Base Stations

Identifying a Three (3) Band Unit

Three (3) band base station normally have an 18MHz wide receive range of 650-668MHz. These three (3) band base stations are designated by having a “3” in the second digit of the two digit band code that is on a label on the rear panel of the unit.

Regulatory Changes and the Three Band

There are two channel map configurations in a three band base station. One for the US/Canada and one for the rest of the world. At one time (before October, 2018) there was only one channel map for a three band unit. but due to regulatory changes in the US/Canada an additional map was produced and installed in three band base stations. The result of the FCC incentive auction in regard to wireless intercom was the following:

• Only 10MHz (653-663MHz) may be used for wireless intercom in the range 616MHz to 698MHz.
• Three band beltpack transmit power must be reduced to 20mW EiRP for US and Canadian units.
  Since the three band units are made for worldwide customers, the 18MHz range is the default shipped, therefore a US or Canadian user must set a base station to the new US channel map in order for the base's channel map to match the US three band beltpack's channel map. The US three band beltpacks only have the new US channel map in them.

NOTE: Only Canadian users of the three band base station needs to change the channel map of the base station to the US channel map!

Changing Channel Maps

A three band base station may be changed from a normal channel map to a US channel map and back again with the press of a couple of buttons. The current channel map setting is remembered by the unit even if power is removed.

1. At the base station's main operating screen press and hold [SET]+[UP] buttons until the switching band text is displayed.
   The three band map the unit is switching to will be displayed.
2. Release the buttons when switching three band text is shown.
   Unit will reboot and display one of the following channel map versions on boot:
   X30001 = Normal three band channel map
   X3U001 = US three band channel map
   (where X is the current transmit band of the base station.)
