½ HDMI Inputs: The 4 HDMI Inputs are located in the center of the back panel. The Inputs have a

blue LED which will light when a source is connected and synced.

½ HDMI and CAT5e/6 Outputs: There are 4 sets of HDMI Outputs and their associated CAT5e/6

Outputs located on either side of the HDMI Inputs. Both HDMI and CAT5e/6 Outputs have a
blue LED which will light when a display/Balun is connected and synced.

½ The HDMI and CAT5e/6 Outputs are both active simultaneously.

½ There are 4 Serial IR Inputs located on the right side of the back panel. These are standard

3.5mm mono jacks. Connect these to any control system for routing IR over the CAT5e/6
outputs.

½ The RS-232, Serial IR, Optical IR Sensor, Operation Mode Switch and Power connections

are located on the right side of the back panel. The Operation Mode switch is only used to
update the unit’s firmware which is done using the DB9/RS-232 port. The firmware version as
well as all RS-232 commands is available through the RS-232 command ‘H’. A detailed list of
RS-232 commands is available later in this guide.

½ If newer firmware is made available, complete updating instructions will be included with it.

KD-CATHD4x4Rx Baluns

If you will be utilizing the KD-CATHD4x4Rx Baluns (included), please follow this procedure.

½ 2 CAT5e/6 UTP or STP cables need to be used.

½ Be careful to connect the “Video/Audio” jacks

to each other and the “Data” jacks to each
other. Do not cross these connections.

½ Use the shortest length HDMI cable you can

when connecting the Balun to the Display.

½ Ensure that the 2 cables are run directly from

the switcher to the Baluns.

½ Do not use patch panels, punch downs or wall plates.

½ Each Balun is supplied with a power supply.

½ Key Digital recommends the use of CAT5e/6 STP cable with shielded RJ45

connectors for optimum performance and distances from your Balun.
