About this Guide

This guide describes the Extron DTP T USW 333 switcher with an integrated DTP transmitter. The switcher outputs a signal to a compatible DTP receiver. This guide describes how to install, operate, and configure the switcher.

NOTE: In this guide, the DTP T USW 333 is commonly referred to as a "switcher" or a "switching transmitter."

About the DTP T USW 333 Switcher

The DTP T USW 333 is a 3 input VGA and HDMI switcher with a DTP transmitter output (see figure 1). It switches among one analog VGA and two HDMI inputs, including embedded audio (or DVI video with the appropriate adapters). The switcher converts the selected input, an optional analog audio input, and bidirectional RS-232 and infrared (IR) control signals to a proprietary digital signal. It outputs the signal to a compatible DTP receiver. The switcher and receiver extend the usable distance of video, audio, and control signals up to 330 feet (100 meters) over a single shielded twisted pair cable (STP).

Figure 1. Typical Switching Transmitter Application

NOTE: In figure 1, the effective range between the DTP T USW 333 and the IN1608 is 230 feet (70 meters). This is the range limitation of the IN1608, not the DTP T USW 333.

The DTP T USW 333 is housed in a half rack width metal enclosure. It can be set on a tabletop, mounted in a rack, or mounted under or through furniture.

The included external desktop 12 VDC power supply accepts 100 to 240 VAC, 50-60 Hz. A single power supply connected to either unit can power both units through the STP cable.

STP Cable

Extron recommends XTP DTP 24 shielded twisted pair (STP) cable for best performance. Extron recommends at least 24 AWG, solid conductor, STP cable with a minimum bandwidth of 400 MHz.

ATTENTION:

Twisted pair cable is smaller, lighter, more flexible, and less expensive than coaxial cable. The DTP 330-enabled products make cable runs simpler and less cumbersome. Termination of the cable with RJ-45 connectors is simple, quick, and economical.

Control Communications

Control this device through the front panel USB port, the rear panel RS-232 port, or through a DTP matrix. The RS-232 and IR communications are pass-through only. The switching transmitter and receiver do not generate or respond to the RS-232 and IR communication signals.

• HDBaseT-enabled receiver type — Set this switch to HDBT position. The TP output consists of HDMI with embedded audio plus RS-232 and IR. The switcher and receiver each requires its own 12 VDC power supply.

D Audio input — If desired, plug an analog audio input into the switching transmitter via this stereo mini jack port.

NOTES:

- The analog audio input on this port is in addition to the digital audio that may be embedded in the HDMI inputs. See the figure at right to identify the connector tip, ring, and sleeve when making connections for the switching transmitter from existing audio cables. A mono audio connector consists of the tip and sleeve. A stereo audio connector consists of the tip, ring, and sleeve.

• If the ground jumpers are removed (see Disconnecting the Ground on page 31) because of ground potential differences, the DTP T USW 333 cannot extend analog audio. The connected receiver outputs no analog audio.
• The analog audio can be assigned to a specific input or set to be always output (see SIS command Assign analog audio input to specific video input or always output audio on page 18).

E Over DTP RS-232 and IR port (see figure 2 on page 6) — Plug a serial RS-232 signal, a modulated IR signal, or both into this 3.5 mm, 5-pole captive screw port for bidirectional RS-232 and IR communication (see IR and RS-232 connectors wiring on page 11 to wire the connector).
F DTP Output RJ-45 port — Plug one end of a STP cable to this RJ-45 female port on the switching transmitter. Plug the opposite end of this cable into the DTP Input RJ-45 port on a compatible receiver (see STP cable termination and recommendations on page 9 to properly wire the RJ-45 connector and for detailed NOTES).

ATTENTION:

• Signal LED — Lights when the unit is outputting a TMDS clock signal on the DTP output.
- Link LED — Indicates a valid link is established between the units.

Remote Contact port — If desired, for contact closure control, plug a locally-constructed contact closure device into this 3.5 mm, 4-pole captive screw port. Momentarily short the pin for the desired input (1, 2, or 3) to G to select that input. To force an input to be always selected, leave the short in place (see Contact Closure Control on page 15).

NOTES:

• Contact closure control overrides front panel input selections.
• For contact closure control, auto switch mode must be off (see Selecting the switch mode on page 14).

Remote Tally port — If desired, to remotely identify the currently selected input, plug a locally-constructed device into this 3.5 mm, 4-pole captive screw port. Connect the power wire for the device into the +V pin and connect the ground wire for each indicator into the corresponding tally out pin, 1, 2, or 3.

When an input is selected, by contact closure, front panel selection, or SIS, the corresponding tally out pin shorts to ground, closing the circuit and lighting the connected indicator (LED).

1 Remote RS-232 port — Plug a serial RS-232 device into the switching transmitter via this 3.5 mm, 3-pole captive screw port for remote control of the switching transmitter (see IR and RS-232 connectors wiring on page 11 wire the connector).

Figure 3. VGA Connector Wiring

HDMI connector

HDMI signals run at a very high frequency and are especially prone to errors caused by bad video connections, too many adapters, or excessive cable length. To avoid the loss of an image or jitter, follow these guidelines:

• Do not exceed 16.4 feet (5 meters) on the input of the transmitter or the output of the connected receiver.
• Use only the cable designed for HDMI signals that is supplied by Extron.
• Limit or avoid the use of adapters.
• Use only cables specifically intended for HDMI or DVI signals. Use of non-HDMI or non-DVI cables or modified cables can result in a missing video output.

To securely fasten an HDMI cable to a device:

1. Plug the HDMI cable into the panel connection (see figure 4, ①).
2. Loosen the HDMI connection mounting screw from the panel enough to allow the LockIt lacing bracket to be placed over it (②). The screw does not have to be removed.
3. Place the LockIt lacing bracket on the screw and against the HDMI connector, then tighten the screw to secure the bracket (③).

Figure 4. Installing the Locklt Lacing Bracket

ATTENTION:

• Do not overtighten the HDMI connector mounting screw. The shield to which it fastens is very thin and can easily be stripped.

• Ne serrez pas trop la vis de montage du connecteur HDMI. Le blindage auquel elle est attachée est très fin et peut facilement être dénudé.

• Loosely place the included tie wrap around the HDMI connector and the LockIt lacing bracket as shown (4).

• While holding the connector securely against the lacing bracket, use pliers or similar tools to tighten the tie wrap, then remove any excess length (⑤).

STP cable termination and recommendations

Figure 5 details the TIA/EIA T 568B wiring standard. Use this standard to terminate the DTP cable with RJ-45 connectors.

Figure 5. STP Cable Termination

ATTENTION: Do not use Extron UTP23SF-4 Enhanced Skew-Free AV UTP cable or STP201 cable to link the switching transmitter and receiver. The DTP T USW 333 does not work properly with these cables.

The DTP T USW 333 is compatible with shielded twisted pair (STP) and unshielded twisted pair (U/UTP) cable. However, Extron strongly recommends that you use STP cable to achieve best performance.

Cable recommendations

Extron recommends using the following practices to achieve full transmission distances up to 330 feet (100 meters) and reduce transmission errors.

• Use the following Extron XTP DTP 24 STP cables and DTP 24 connectors for the best performance:

• XTP DTP 24/1000 Non-Plenum 1000 feet (305 meters) spool
  • XTP DTP 24P/1000 Plenum 1000 feet (305 meters) spool
  • XTP DTP 24 Plug Package of 10

• If not using XTP DTP 24 cable, at a minimum, Extron recommends 24 AWG, solid conductor, STP cable with a minimum bandwidth of 400 MHz.

• Terminate cables with shielded connectors to the TIA/EIA-T568B standard.
• Use no more than two pass-through points, which may include patch points, punch down connectors, couplers, and power injectors. If these pass-through points are required, use Catagory 6 or 6a shielded couplers and punch down connectors.

NOTE: When using STP cable in bundles or conduits, consider the following:

• Do not exceed 40% fill capacity in conduits.
• Do not comb the cable for the first 20 meters, where cables are straightened, aligned, and secured in tight bundles.
• Loosely place cables and limit the use of tie wraps or hook-and-loop fasteners.
• Separate twisted pair cables from AC power cables.

Power supply wiring

NOTES:

• The power supply included with the switching transmitter can normally power both units.
• If you have removed the ground jumpers (see Disconnecting the Ground on page 31) because of ground potential differences, one unit of the pair cannot remotely power the other unit. Each unit requires a local power supply.

Figure 6 shows how to wire the connector. Use the supplied tie-wrap to strap the power cord to the extended tail of the connector.

Figure 6. Power Connector Wiring

CAUTION:

ATTENTION :

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

IR and RS-232 connectors wiring

Figure 7 shows how to wire the Remote RS-232 and Over DTP RS-232 and IR connectors.

The RS-232 and IR connectors share the ground pole and the data from both can be transmitted simultaneously.

Figure 7. IR and RS-232 Connectors Wiring

NOTES:

• The IR Tx and Rx line pair and the RS-232 Tx and Rx line pairs must each cross once between their ports and the source or destination.
• The length and preparation of exposed wires is important (see the second and third power Caution on page 10).

Front Panel Configuration Port

A Configuration port — Connect a USB mini-B cable to this port for remote control of the switching transmitter, similar to the communications function of the rear panel Remote RS-232 port.

NOTE: A front panel configuration port connection and a rear panel Remote RS-232 port connection can both be active at the same time. If commands are sent simultaneously to both, the command that reaches the processor first is handled first.

Normal button — The Normal button is used with the Mode button to select normal mode (see Selecting the switch mode).

This button is a secondary function of the Input 2 button. When you change from auto-input switching to normal (manual) mode, the last input selected in auto-input switching mode remains selected until you manually select a different input.

Auto (switch) button (see figure 9 on page 12) — The Auto button is used with the Mode button to select auto-input switching mode (see Selecting the switch mode).

This button is a secondary function of the Input 3 button.

Status LEDs

G Status LEDs —

• Signal LEDs (1 through 3) — Indicates that the switcher detects horizontal sync (Signal LED 1) or TMDS clock (Signal LED 2 and Signal LED 3) on the associated input.
• HDCP LEDs (2 and 3) — Indicates that the input signal is HDCP-encrypted.

Front Panel Operations

The following paragraphs detail the power up process and provide sample procedures for switching inputs, changing between normal and auto-input switching mode, and toggling executive mode on and off.

Power

Power is automatically applied when the power cord is connected to an AC source. When AC power is applied, the switcher performs a self-test that blinks the front panel LEDs during the test. An error-free power up self-test sequence leaves the Auto Switch and Input LEDs on or off in the same configuration as they were when power was last removed.

If an error occurs during the self-test, the switcher locks up and does not operate. If the switcher locks up on power-up, call the Extron S3 Sales & Technical Support Hotline. See the Extron website for the nearest Extron office.

Plug in all system components and turn on the input devices (such as Blu-Ray players and computers) and the output devices. Set the input devices to output video using the operating instructions of that device. Select an input. The image should appear on the screen. If no image appears, see Troubleshooting — If No Image Appears on page 14.

Switching inputs

Select an input for transmission to the receiver using the front panel buttons as follows:

1. Select the desired input by pressing the associated input button (see figure 10).

Figure 10. Selecting an Input

1. Observe that the LED for the selected input lights.

NOTE: The switcher must be in normal (manual) mode.

An input can also be selected using an RS-232 or USB device or a contact closure device (see Remote Control starting on page 15).

Selecting the switch mode

NOTE: In the auto-input switching mode available from the front panel, the switcher selects the highest numbered input with a sync signal present. See the SIS command Front panel mode on page 18 to configure auto-input switching low mode, which selects the lowest numbered input.

Turn auto-input switching mode on and off as follows:

1. Press and hold the Mode (Input 1) button and the button for the desired mode for approximately 5 seconds (see figure 11):

• Auto (Input 3) — The Auto Switch LED lights.
- Normal (Input 2) — The Auto Switch Active LED goes off.

    F["Auto Switch lights (auto) or goes out (normal)."] --> D

Figure 11. Selecting a Mode

1. Release the buttons.

Front panel security lockout (Executive mode)

The switcher has a front panel lock feature that locks the front panel. If front panel input selections are attempted when the panel is locked, all front panel LEDs blink three times.

Toggle the front panel lock on and off as follows:

1. Push and hold the Input 1, Input 2, and Input 3 buttons simultaneously for 5 seconds. All front panel LEDs blink three times.

2. Release the buttons.

When the front panel is locked, contact closure, USB, and RS-232 control are still available.

Reset

Use the recessed rear panel Reset button to reset to default settings as follows:

1. Press and hold the Reset button for approximately 6 seconds. All front panel LEDs cycle.
2. Release the button. This reset is the equivalent of issuing the Esc ZXXX← SIS command (see Reset on page 20).

Troubleshooting — If No Image Appears

1. Ensure that all devices are plugged in and powered on. The switcher is receiving power if one of the input LEDs is lit.
2. Ensure an active input is selected on the switcher or that the switcher is in auto-input switching mode.
3. Ensure that the proper signal format is supplied.
4. Check the cabling and make corrections as necessary.
5. Call the Extron S3 Sales & Technical Support Hotline if necessary (see the Extron website for the nearest Extron office).

Remote Control

This section includes:

• Contact Closure Control
  • Simple Instruction Set Control
  • Product Configuration Software

The DTP T USW 333 switcher can be remotely controlled via its rear panel Remote RS-232 port, its front panel configuration (USB) port, and its rear panel Remote Contact port. Remote control devices can be:

• A host device such as a computer or control system and the Extron Simple Instruction Set
• A contact closure device such as an Extron KP 6 Keypad Control or a video cable

Contact Closure Control

The rear panel Remote Contact port (see figure 2 on page 6) provides a way to select an input to the switcher using a remote contact closure device. The contact closure pin assignments are shown in figure 6 on page 10.

NOTE: The switcher must be in normal (manual) mode.

To select a different input number using a contact closure device, momentarily short the pin for the desired input number to ground. To force one of the inputs to be always selected, leave the short to ground in place. The short overrides front panel input selections.

Simple Instruction Set Control

The DTP T USW 333 switching transmitter can be remotely controlled using SIS commands from a host device such as a computer or control system via its rear panel Remote RS-232 port (see ① on page 7) or front panel configuration (USB) port (see Front Panel Configuration Port on page 12).

The default serial port protocol of the port is as follows:

• 9600 baud • No parity • 8-bit
- No flow control • 1 stop bit

Host-to-Switcher Communications

SIS commands consist of one or more characters per field. No special characters are required to begin or end a command character sequence. When a command is valid, the switcher executes the command and sends a response to the host device. All responses from the switcher to the host end with a carriage return and a line feed (CR/LF = ←), which signals the end of the response character string. A string is one or more characters.

Switcher-Initiated Messages

When a local event occurs, such as a front panel operation, loss or restoration of an input signal, or an error condition, the switcher responds by sending a message to the host. The switcher-initiated messages are listed below:

© Copyright 20yy, Extron Electronics DTP T USW 333, Vx.xx, 60-nnnn-nn

The switcher issues the copyright message when it first powers on. vx.xx is the firmware version number and 60-nnnn-nn is the part number.

Inn All

The switcher also sends the Inn message whenever the selected input is changed. n is the input number. A zero (θ) in the n field indicates no input is selected.

Error responses

When the switcher receives a valid SIS command, it executes the command and sends a response to the host device. If the switcher is unable to execute the command because the command is invalid or it contains invalid parameters, the switcher returns an error response to the host. The error response codes are:

E01 — Invalid input channel number (out of range)

E06 — Invalid channel change

E10 — Invalid command

E13 — Invalid parameter

Timeout

Pauses of 10 seconds or longer between command ASCII characters result in a timeout. The command operation is aborted with no other indication.

Using the Command and Response Table

The Command and Response Table for SIS Commands starts on page 18. Symbols are used throughout the table to represent variables in the command and response fields. Command and response examples are shown throughout the table. The SIS commands are not case sensitive. The ASCII to HEX conversion table below is for use with the command and response table.

Reference Information

This section provides procedures for mounting the DTP T USW 333 switching transmitter and disconnecting the ground between it and a compatible receiver.

• Mounting the Switcher
  • Disconnecting the Ground

Mounting the Switcher

ATTENTION:

The 1-inch high, half rack width DTP T USW 333 switching transmitter can be placed on a table, mounted in a rack, or mounted under a desk or table.

Tabletop Use

Affix the included rubber feet to the bottom of the unit and place it in any convenient location.

Mounting kits

Mount the unit using any optional compatible mounting kit listed at www.extron.com, in accordance with the directions included with the kit. For rack mounting, see UL Rack-Mounting Guidelines on page 30.

UL Rack-Mounting Guidelines

The following Underwriters Laboratories (UL) requirements pertain to the installation of the DTP T USW 333 into a rack.

CAUTION:

• Elevated operating ambient temperature — If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consider installing the equipment in an environment compatible with the maximum ambient temperature (TMA = +122°F, +50°C) specified by Extron.
• Reduced air flow — Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
• Mechanical loading — Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
• Circuit overloading — Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing this concern.
• Reliable earthing (grounding) — Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (such as use of power strips).

Disconnecting the Ground

If you cannot resolve a ground potential difference between the switching transmitter and receiver installation sites (as suggested by a missing or unstable picture), remove the ground connection between the units as follows:

NOTE: Once the ground jumpers are removed, the DTP T USW 333 cannot extend analog audio or remote power. No analog audio is output and the paired receiver requires its own dedicated power supply.

1. Disconnect any cables and remove the switching transmitter from any rack or other installation option.
2. Remove and retain the screws (nine screws, three on each side and three on top) securing the cover to the switching transmitter. Slide the cover forward slightly and lift it off the unit (see figure 19).

TIP: Do not to bend the electrical contact "legs" of the button and LED assemblies on the circuit board. If the buttons or LEDs are misaligned with the holes in the cover, it may be difficult to reassemble the switcher.

Figure 27. Opening the Switching Transmitter

1. Locate and lift off jumpers JMP1 and JMP2 (see figure 20).

Figure 28. Jumper Locations

1. Reinstall the switcher cover, securing it in place with the screws removed in step 2.
2. Reinstall the switcher in the rack or other installation option (see Mounting the Switcher on page 29).

3. If you are using shielded cable, disconnect the cable shield from the connector at either end of the cable.

4. See the manual for the applicable receiver available at www.extron.com, and remove the ground jumpers in the receiver.

5. Obtain a second 12 V power supply (one supply is provided with the switching transmitter and normally powers both units), and locally power both units (see Power supply wiring on page 10).
