Frequently Asked Questions - EXT-DVIKA-LANS-TX Gefen
What is the Gefen EXT-DVIKA-LANS-TX used for?
The Gefen EXT-DVIKA-LANS-TX is a transmitter designed to extend DVI video, USB keyboard/mouse signals, and analog audio over a single Ethernet cable. It typically works with a matching receiver (e.g., EXT-DVIKA-LANS-RX) to place a computer workstation up to 100 meters away.
What is the maximum resolution supported?
The extender supports resolutions up to 1920x1200 @ 60Hz (WUXGA) for crisp, high-definition video. For best result, use a compatible source and display.
How far can the signal be transmitted?
Using reliable Cat6 cabling, the signal can be transmitted up to 100 meters. Cat5e may support slightly shorter distances due to bandwidth limitations.
What type of cable is required?
You need a Cat5e or Cat6 Ethernet cable with standard RJ-45 connectors. The cable must be terminated according to TIA/EIA-568B wiring standards. Avoid using patch panels or additional switches in the path for maximum performance.
How do I connect a keyboard and mouse?
Connect the USB keyboard and mouse to the two USB Type-A ports on the transmitter, or plug them into the receiver's USB ports if available. The extender uses standard USB HID driver, so there is no additional software required.
Does this unit require a matching receiver?
Yes, the EXT-DVIKA-LANS-TX is a transmitter and must be paired with a compatible Gefen receiver (model EXT-DVIKA-LANS-RX). The receiver converts the LAN signal back into DVI, USB, and audio outputs.
What power adapter is needed?
The unit requires a 5V DC power adapter with at least 1A output. Use the included adapter to avoid damage. The power connector is a standard 2.1mm barrel jack.
Can I use this extender with a non-Gefen receiver?
No, it is designed to work only with the matched Gefen receiver, as the link protocol is proprietary. Using other receivers will result in no signal or damaged equipment.
Is the unit hot-swappable?
Yes, the HDMI-input and USB ports support hot-plugging, meaning you can connect or disconnect devices while the extender is powered. However, always turn off power when connecting or disconnecting the Ethernet cable to prevent potential damage to the transceiver.
How should I clean and maintain the device?
To clean the unit, use a soft, dry microfiber cloth to gently wipe the exterior. Do not use liquids, sprays, or compressed air. Turn off power and unplug the adapter before cleaning. Keep the device away from moisture, direct sunlight, and heat sources to ensure long reliable service.
