NOTE: Other SFPs may work but have not been validated by Black Box, we recommend you use the suggested SFPs to avoid technical incompatibilities. SFP is not included in the package and must be ordered separately.
- Connect one end of an HDMI cable to the HDMI port on the source device (e.g. computer, server, or other IT device). Then connect the other end to the HDMI IN port located on the TX unit.
- Connect the HDMI display to the HDMI OUT port on the TX unit.
- Connect the HDMI display to the HDMI OUT port on the RX unit.
- Connect the USB ports of the source device and the TX unit with a USB type A-B cable. Then plug a USB keyboard, mouse, or other USB devices into the USB ports of the RX unit.
- Connect the RS-232 ports of the source device and the TX unit. Then connect the RS-232 ports of the RS-232 device on the RX unit side and the RX unit.
- Connect the microphone/speaker ports of the source device and the TX unit with the audio microphone/speaker combo cable of the accessory. Then, plug the microphone and speaker into the microphone and speaker ports of the RX unit.
- For the CATx model, use a CAT5e cable to connect the CATx link ports on the TX unit and the RX unit.
- For the fiber model, use two SFP modules and an optical fiber cable to connect the fiber link ports on the TX unit and the RX unit.
- Plug the power adapter cable into the DC jacks on the TX and RX units.
NOTES:
a. We recommend using the highest quality materials (cables, SFP, etc.) to
ensure optimal transmission quality.
b. If the screen does not display when you connect the computer:
- Make sure the device cables are correctly and firmly attached.
- Set your display device’s (TV, monitor, etc.) input source as HDMI.
- Check the PC BIOS configuration of the video output setting.
- Connect your video source to the Display DIRECTLY to check if the video signal gets through.
NOTES:
- Both the HDMI displays respectively connecting to TX and RX units MUST support the same maximum video resolution.
- SFP module’s bandwidth requirement is 1 Gbps minimum.
- When plugging into any microphone or speaker ports of TX or RX units, digital HDMI audio extension will be disabled, and only analog audio LINE-IN/LINE-OUT extension is enabled.

OVERVIEW
INTRODUCTION
The KVX Series 4K HDMI KVM Extenders (single-head) enable you to locally use a
4K HDMI monitor, USB keyboard/mouse/other devices, speaker, and microphone to
operate a remote computer, server, or other IT device featuring a 4K HDMI
video output. You can also view the 4K HDMI video output of the remote source
devices via the HDMI output port on the 4K HDMI KVM Extender’s TX unit. Dual-
head models support (1) HDMI and (1) DisplayPort inputs on the transmitters to
accommodate video cards with multiple outputs, and (2) HDMI outputs on the
receivers.
There are six models of the KVX Series 4K HDMI KVM Extender: the single-head
models are KVXLCH-100 via a CATx link and KVXLCHF-100 via a fiberoptic link.
The dual-head models are KVXLCH-200 and KVXLCHDP-200 via a CATx link and
KVXLCHF-200 and KVXLCHDPF-200 via a fiberoptic link. Each extender consists of
a transmitter (TX) and a receiver (RX).
FEATURES
- Single-head models support HDMI input/output video quality up to 4K @ 30 Hz, 3840 x 2160 @ 30 Hz.
- Dual-head models support HDMI or DisplayPort input/HDMI output video quality up to 4K @ 30 Hz, 3840 x 2160 @ 30 Hz.
- Has 4K HDMI local video loopback on the single-head TX units and 4K HDMI/DisplayPort local video loopback on the dual-head TX units
- Provides remote access for video/USB/RS-232/audio extension distance up to 330 feet (100 meters) over CATx cable for model KVXLCH-100 or KVXLCH-200 and KVXLCHDP-200; up to 18.6 miles (30 km) over fiberoptic cable for model KVXLCHF-100 or KVXLCHF-200 and KVXLCHDPF-200, depending on the SFP used.
- The HDMI KVM Console Extender lets you control a server, or computer over single-mode or multimode fiber optic cable at distances of up to 30 km (depending on the SFP used, fiber type, and fiber bandwidth*).
- Offers transparent USB 2.0/1.1 extension.
- Uses analog audio LINE-IN/LINE-OUT extension.
- Supports bi-directional RS-232 control communication at a fixed baud rate of 115200.
- Automatic EDID update.
