4. Setup Instructions
Follow these steps to set up your JTECH-KVE2 Extender system. Ensure all devices are powered off before making connections.
Figure 4.1: Typical Connection Diagram.
- Connect Source to Transmitter: Use an HDMI cable to connect your HDMI source device (e.g., computer, game console) to the HDMI In port on the Transmitter unit.
- (Optional) Local Display: If desired, connect a local HDMI display to the HDMI Out (Loop) port on the Transmitter unit for local monitoring.
- Connect PC for KVM: Use the provided USB cable to connect your PC's USB port to the USB Type-B (PC In) port on the Transmitter unit.
- Ethernet Cable Connection: Connect a single CAT6, CAT6a, or CAT7 Ethernet cable between the CAT (RJ-45) port on the Transmitter unit and the CAT (RJ-45) port on the Receiver unit. Ensure the cable is of good quality and within the maximum recommended length of 328 feet (100 meters).
- Connect Displays to Receiver: Use HDMI cables to connect your display devices (e.g., monitors, TVs) to the HDMI Out 1 and HDMI Out 2 ports on the Receiver unit.
- Connect KVM Devices: Connect your USB keyboard and USB mouse to the respective USB 2.0 ports on the Receiver unit. Note that these ports are primarily designed for keyboard and mouse devices.
- (Optional) Audio Connections: Connect external audio devices to the 3.5mm Audio Out port on the Transmitter or the 3.5mm Audio In port on the Receiver as needed.
- (Optional) IR Control: Connect the IR Blaster cable to the IR Out port on the Transmitter and position the emitter near the IR sensor of your source device. Connect the IR Receiver cable to the IR In port on the Receiver and position the receiver in a location where it can pick up signals from your remote control.
- Power On: Connect the two included 5VDC power adapters to the Power (DC/5V) ports on both the Transmitter and Receiver units. Plug the adapters into a power outlet. The units will power on automatically.

5.3. Audio Extraction and Input
The 3.5mm Audio Out port on the Transmitter allows you to extract analog audio from your HDMI source. The 3.5mm Audio In port on the Receiver allows for audio input at the remote location. This provides flexibility for integrating external audio systems.
Figure 5.2: 3.5mm Audio Extraction Ports.
5.4. EDID Management
The EDID (Extended Display Identification Data) switch on the Transmitter unit helps ensure compatibility between the source and display devices. You can select from the following modes:
- Local: The Transmitter uses the EDID of the local display connected to its HDMI Out (Loop) port.
- Remote: The Transmitter uses the EDID of the display connected to the Receiver's HDMI Out 1 port.
- Default: The Transmitter uses a built-in default EDID.
If you encounter display issues (e.g., no picture, incorrect resolution), try adjusting the EDID switch to a different setting.
