Frequently Asked Questions - EXI 3591 KATHREIN

How do I configure the integrated K-LAN modem?

For simple commissioning, connect the modem to the switch via a coaxial cable. Connect the router and receiver to the RJ45 socket using the supplied Ethernet cable. The Power and Coax/Link LEDs should light up. For a private network, use the Pairing button.

How do I activate PIN code protection?

The PIN code is assigned to each user band (UB). You must enter it during receiver setup. Refer to the PIN table in the manual: e.g., UB1 = 151, UB2 = 052, etc. To deactivate, check the receiver menu.

What should I do if the message 'weak signal or no signal' appears?

First, ensure the receiver is powered on and in single-cable mode. Check the cables for short circuits. If the problem persists, verify the PIN code and frequency assignment (UB). For UB9, the receiver must support the SCD2 standard (prTS 50607).

How do I pair multiple modems in a private network?

Press the Pairing button on each modem for about 12 seconds to delete the network key. Then briefly press (1 second) the Pairing button on one modem, then within 3 minutes on the second. The Power and Coax/Link LEDs remain lit continuously. Repeat for each modem.

What is the function of Kathrein Power Saving?

This function cuts off power to the LNB as soon as no receiver is active, reducing energy consumption. If other switches in the cascade do not support this function, set the standby switch to OFF for continuous LNB power supply.

Can I use standard coaxial cables?

Yes, but the inner conductor diameter must be between 0.6 and 1.2 mm, without burrs, to avoid damaging the female connectors. Use F connectors 75 Ω according to EN 61169-24.

How do I reset the modem?

Briefly press (1 to 3 seconds) the Reset button. Factory settings are restored, including the original network key. The modem becomes visible to all and is no longer part of the private network.

What do the LEDs on the modem mean?

LED Power: solid green = in service; solid red = standby; off = no power. LED Coax/Link: green = good coaxial connection; orange = average connection; red = poor connection; off = attenuation > 90 dB or no network key.

What accessories are recommended with the EXI 3591?

The single modem EXI 01 to reconvert IP data on an Ethernet socket, the high-pass filter EXI 90 to isolate non-EXI switches, and the EXI 700 software to visualize modems in the network. ESU series outlets are also compatible.

How do I install the switch in cascade with other devices?

Ensure that the passing multiswitches support Kathrein Power Saving. For the modem, use the integrated high-pass filter to block IP frequencies from the terrestrial antenna. Maintain a minimum clearance of 5 cm around the device for ventilation.

USER MANUAL EXI 3591 KATHREIN

Single cable multi-switch with integrated modem

K Power Saving

Features single-cable multi-switch

Cascadable single-cable multi-switch with an integrated modem for the distribution of Sat-IF signals (four Sat polarisations) and terrestrial signals to up to nine receivers
The selected transponder is transmitted by the multi-switch on a fixed frequency (user band), controlled by the receiver with a DiSEqCTM command set conforming to EN 50494
The multi-switch supports the extended single-cable set of commands SCD2 conforming to prTS 50607 (see also "Notes" section)
Terrestrial signals can be received even when the satellite receiver is switched off
Each receiver is assigned a fixed subscriber frequency (a twin receiver requires two subscribers frequencies)
Creation of a home network using the existing terrestrial distribution. The IP data is available on every subscriber output. Installation complexity is reduced as no additional network cabling is required.
PIN Code: Protects the user frequency from being accessed by another user. This allows an installation in an apartment building

Integrated AGC (Automatic Gain Control) ensures a constant output level in the Sat-IF range
Integrated, highly-selective frequency diplexer for IP data
Low power consumption due to highly efficien, short-circuit proof switchedmode power supply unit in compliance with ERP guideline and energy-saving concept (the single-cable multi-switch is switched off whenever the connected receiver is switched off)
Kathrein-Power-Saving: LNB supply is switched off as soon as all receivers are inactive. This function can be deactivated if loop-through multi-switches without Kathrein Power Saving are used in the cascade
LNB remote feeding via the horizontal low input. Signaling Kathrein power saving over the trunk "vertical low." All other inputs are voltage-free
For indoor installation
CCL

Features built-in modem

Modem for Kathrein IP over coax system "K-LAN" (based on the standard IEEE 1901)
- Ideal for networking of receivers, TV sets and Blu-ray players. Other network-capable units such as PCs can also be easily connected using a router (e.g. FRITZ!Box)

500-Mbit data throughput (gross) allows several HD streams during simultaneous data transmission between PCs. Due to QoS * relevant services are prioritised
High screening values ensure disturbance security
128 bit AES encryption: Secure, private network connection at the press of a button - no software required
- Eco Power Mode: The modem switches automatically to "stand-by" and is "woken up" again through the network. Consumption: 1.0 watts in stand-by mode/4.2 watts in operational mode

Accessories

• Sockets of the ESR series are used despite limited frequency range for K-LAN.
  Protection of the system function in receiver malfunction: power of the connected receiver, if this is not the single-cable DiSEqCTM instruction set according to EN 50494 is used (cutting off the power from the satellite terminal to input at +18 VDC to 400 ms)
  End-user modem EXI 01 (Order no. 20510061): To reconvert IP data on subscriber outlets (e.g. to connect a satellite receiver with an Ethernet port)
• Software EXI 700: Shows the functioning modems in a network (Downloadable from: www.kathrein.de)
  High pass EXI 90 (BN 20,510,062): If additional multi-switch (not from the EXI series) cascade and the EXI 01 is operated at one of these multi-switch, the high-pass must be screwed onto the terrestrial input of the multiswitch. This subsequent multiswitches are isolated and prevented the incoming and outgoing radiation of the frequency range of IP and terrestrial antenna in the cascade. EXI 3591 in the high-pass is already integrated

Kathrein Power Saving

If an EXI 3591 is run on its own or alongside other multi-switched Kathrein-Power-Saving-logo devices, then Kathrein power saving switch can be activated with the "On" button. If a receiver is switched on in the cascade, from the end of the LNB multiswitch is powered.

Uses without Kathrein Power Saving do not give signalling to the end multi-switch. The stand-by switch must be set to "OFF" for permanent powering of the LNB.

Type Product	type Kathrein Power	Saving Switch position
VWS 2551 Amplifiers		Can be used without restriction Note: If the terrestrial frequency range is used, the VWS (amplifier) must be locally powered.	ON
EBX 2520 Two-way splitter		Can be used without restriction if each trunk has been terminated with a Kathrein Power Saving-capable end multi-switch.	ON
EAX 2512 Two-way tap		Not compatible with Kathrein Power Saving	OFF
VWS 2500 Amplifiers		Not compatible with Kathrein Power Saving	OFF

PIN code protection

The multi-switch is protected by a PIN code in order to prevent the set userband from being used/disturbed by another subscriber. This should be specified in the receiver settings. A fixed PIN has been assigned to each userband.

	UB 1 UB 2 UB 3 UB 4 UB 5 UB 6 UB 7 UB 8 UB 9
Frequency (MHz)	974 10	076 1178	1280 13	82 1484	1586 16	88 1790
Pin 151 052	133 124	205 196	187 178	8 099

Notes

Only use splitters without diodes (EBC 110 or EBC 114). The required diode protection is provided by outlets from the ESU series.

By definition the system is designed so that single-cable units are supplied with 14 V DC. The power supply is briefly switched to 18 V DC if control signals similar to DiSEqCTM have to be transmitted. Continuous application of 18 V would block the system.

Sockets of the ESR series are specified in the data sheet from 47 MHz. The very small directional losses in the range 5-47 MHz used in the K-speed modems in this case, is an advantage. They can therefore be used without any problems.

It is recommended to assign the outlets with the shorter cable lengths the higher frequencies.

The multi-switch (with integrated modem) EXI 3591 is ideally used in combination with the single modem EXI 01. The subscriber of this multi-switch is specially adapted to terrestrial and offers the optimum conditions for the data rates of the modem to EXI 3591 but also between multiple EXI 01s. An integrated high pass filter for terrestrial input prevents unwanted distribution of your network data on a connected antenna.

To achieve optimum performance, make sure when your entire distribution that supports the frequency range 5-68 MHz.

The receivers that are connected must be designed for single-cable operation conforming to EN 50494. In order to use userband 9, the receiver must also support the single-cable standard SCD2 as per prTS 50607.

Startup of the modem

The integrated modem in the multi-switch EXI 3591 and the Kathrein modem EXI 01 are secured from the factory with a network key. For easy operation of these two modems must be connected to a coaxial cable to the socket . Connected to the network devices such as routers and receivers are connected using the supplied Ethernet cable to the provided RJ-45 jack. The LEDs „Power“ and „Coax / Link“ light. The data link is established. Up to 64 modems may be connected to each other.

Additional security:

"Ensure" that in a coaxial distribution system all the modems connected are Kathrein. If you want to build a private network with your own modems, proceed as follows:

1. Press about 12 seconds on the button „pairing“. Both LEDs go out momentarily. The network key is deleted. The LED “power” lights “Coax/link” is missing. Perform this step on all your devices that you want to add to a private network through!
2. Now click on one of your modems short (approximately 1 second) on the button "pairing". The "Power" LED starts blinking. Now press the next button shortly modem "pairing". Both modems negotiate a secret network key and connect to each other. You have about three minutes for pressing the second button. When the process is completed, both LEDs light up constantly again. Each additional modem can be added in the same manner to the private network. The pairing can be started from any modem in your private network.

Reset:

With the "Reset" button, the modem to factory setting reset. Since in this case also the original factory network key is set, the modem is generally visible again and no longer belongs to the private network.

Stand-by:

Modem switches after a few minutes without traffic automatically to stand-by mode. The "Power" LED blinks slowly (red - green).
