- Connect KVM Devices: Connect your USB keyboard and/or mouse to the USB ports on the receiver unit.
- Connect Ethernet Cable: Connect a CAT5/5e/6/7 Ethernet cable from your network switch/router (or directly from the transmitter unit) to the LAN RX port on the receiver unit. Ensure the cable is securely seated.
- Connect Power: Plug the provided DC 5V power adapter into the DC 5V port on the receiver unit, then plug the adapter into a power outlet.
- Power On Transmitter: Ensure your AGPTEK HDMI KVM Extender transmitter unit is also powered on and correctly connected to your source device and the network.

6. Operation
Once all connections are made and both the transmitter and receiver units are powered on, the system should automatically detect and extend the HDMI and KVM signals. The display connected to the receiver will show the video output from the source device connected to the transmitter. The keyboard and mouse connected to the receiver will control the source device.
- Signal Transmission: The video and audio signals, along with keyboard and mouse data, are transmitted over the Ethernet cable.
- Multi-Screen Display: If you have multiple receiver units connected to the same network (via a router or switch) as the transmitter, each receiver will display the same source content, allowing for a multi-screen setup.
- USB Driver: If your keyboard or mouse is not recognized, install the USB driver software from the included CD on your source computer.
7. Troubleshooting
If you encounter issues, refer to the following troubleshooting tips:
- No Display/Signal:
- Ensure both the transmitter and receiver units are powered on and their respective power LEDs are lit.
- Verify all HDMI and Ethernet cables are securely connected and not damaged.
- Check that the Ethernet cable type (CAT5/5e/6/7) and length are within the recommended specifications (max 120m for CAT6).
- Confirm the display device is set to the correct HDMI input.
- Test the HDMI source and display directly without the extender to rule out issues with those components.
- Keyboard/Mouse Not Working:
- Ensure the USB cables from the keyboard/mouse are firmly connected to the receiver's USB ports.
- Install the USB driver software from the provided CD on the source computer.
- Try connecting the keyboard/mouse directly to the source computer to confirm they are functional.
- Intermittent Signal/Disconnections:
- Check the quality and integrity of your Ethernet cable. A damaged or low-quality cable can cause instability.
- Ensure the power adapters for both transmitter and receiver are providing stable power.
- If using a network switch/router, ensure it is functioning correctly and not overloaded.
- Reduce the cable length if it is close to the maximum recommended distance.
- Poor Picture Quality:
- Ensure you are using high-quality HDMI and Ethernet cables.
- Check the resolution settings on your source device.
