4. For local monitoring, connect an HDMI display to the HDMI OUT port on the Transmitter unit.
5. If using local audio, connect speakers to the Audio Out jack and a microphone to the Audio In jack on the front panel of the Transmitter unit.

3.3. Receiver Unit Connections

1. Connect your remote HDMI display to the HDMI OUT port on the Receiver unit.
2. Connect your USB keyboard, mouse, or other USB 2.0 peripherals to the USB A ports on the Receiver unit.
3. If using serial control, connect your RS-232 peripheral to the RS232 port on the Receiver unit.
4. For remote audio, connect speakers to the Audio Out jack and a microphone to the Audio In jack on the front panel of the Receiver unit.

4. Operating Instructions

Once the KVM Extender is set up, it operates transparently, extending your computer's signals to the remote location.

4.1. Video and Audio Transmission

The extender supports HDMI video resolutions up to 4K (3840x2160) at 30Hz. Audio signals are transmitted bi-directionally, allowing for both speaker output and microphone input at the remote location.

4.2. USB 2.0 Functionality

The transparent USB 2.0 extension supports various USB devices, including Human Interface Devices (HIDs) like keyboards and mice, as well as mass storage devices. Simply connect your USB peripherals to the Receiver unit's USB A ports.

4.3. Serial (RS-232) Communication

The RS-232 port allows for the extension of serial control signals, enabling communication with compatible peripheral devices at the remote end.

4.4. Local Video Output

The Transmitter unit includes an HDMI OUT port, allowing for a local display to be connected near the source computer. This is useful for monitoring or local operation without affecting the remote extension.

5. Maintenance

The Black Box KVM Extender is designed for reliable operation with minimal maintenance. Follow these guidelines to ensure longevity:

• Keep the units in a cool, dry, and well-ventilated area.
• Avoid exposing the units to direct sunlight, excessive heat, or moisture.
• Clean the exterior of the units with a soft, dry cloth. Do not use liquid or aerosol cleaners.
• Ensure all cable connections are secure and free from damage.

6. Troubleshooting

If you encounter issues with your KVM Extender, refer to the following troubleshooting tips:

6.1. No Video Display

• Check Power: Ensure both Transmitter and Receiver units are powered on and their PWR LEDs are illuminated.
• Check CATx Link: Verify the LINK LED on both units is illuminated, indicating a stable connection. If not, check the CATx cable for proper connection and integrity.
• Check HDMI Cables: Ensure all HDMI cables are securely connected to both the source, extender units, and display.
• Resolution Compatibility: Confirm that your display supports the output resolution of the source device.
• Reboot: Power cycle both the source computer and the KVM extender units.

6.2. USB Devices Not Responding

• Check USB Cables: Ensure the USB A-to-B cable from the source to the Transmitter is connected, and peripheral USB devices are connected to the Receiver's USB A ports.
• Power Cycle: Disconnect and reconnect the USB devices, or power cycle the extender units.
• Device Compatibility: While transparent, some specialized USB devices may have specific power or timing requirements not fully supported. Test with standard HID devices (keyboard/mouse) first.

6.3. No Audio

• Check Audio Cables: Verify audio cables are correctly connected to the audio input/output jacks on both extender units and the respective audio devices.
• Volume Settings: Ensure volume levels are not muted or set too low on the source computer and the connected audio devices.
