6. Operating Instructions
Once all connections are made and devices are powered on, the extender should automatically transmit the video and KVM signals. No specific operating steps are typically required beyond initial setup.
Gain Control Adjustment
For optimal video quality, especially over longer cable runs, the gain control on the receiver unit may need adjustment. If the display appears distorted, flickers, or is not shown, adjust the gain level.
- Locate the Gain Control Knob on the rear of the Receiver unit.
- Refer to the table below or the parameter comparison table on the back of the receiver unit to select the appropriate gain level (0-15) based on your LAN cable length.
- Rotate the knob to the recommended gain setting. Fine-tune as necessary for the best image quality.

7. EDID Function
The extender supports EDID (Extended Display Identification Data) functionality. This feature allows the extender to automatically read and store the display's EDID information, ensuring that the connected computer outputs a video signal compatible with the monitor's optimal resolution and refresh rate. This helps prevent display issues such as flickering or incorrect resolutions.

8. Troubleshooting
- No Display/Flickering Screen:
- Check all cable connections (VGA, USB, LAN, Power) to ensure they are secure.
- Verify that both the transmitter and receiver units are powered on.
- Adjust the Gain Control Knob on the receiver unit according to the length of your LAN cable (refer to Section 6).
- Ensure the LAN cable used is a high-quality CAT5e/6 UTP/FTP cable compliant with EIA/TIA 568B standards.
- Test with a shorter LAN cable if possible to rule out cable length issues.
- Keyboard/Mouse Not Responding:
- Ensure the USB cables are properly connected from the computer to the transmitter, and from the keyboard/mouse to the receiver.
- Confirm that the keyboard and mouse are standard USB devices. The receiver's USB ports are specifically for KVM (keyboard/mouse) functionality.
- Try connecting the keyboard/mouse directly to the computer to verify their functionality.
- Image Quality Issues (Color Distortion, Noise):
- Adjust the Gain Control Knob on the receiver unit.
- Ensure the VGA cables are of good quality and securely connected.
- Check for electromagnetic interference (EMI) from other electronic devices.
