Quick Setup Guide

1. Begin with the KD-4x4CSK/KD-8x8CSK and all input/output devices turned off with power

cables removed.

2. Connect HDMI sources to the appropriate input ports on the KD-8x8CSK.

3. Connect display devices to the HDMI output ports and audio devices to audio output ports.

4. Connect power to the KD-4x4CSK/KD-8x8CSK as well as to all other input and output

devices and turn them on.

5. Operate the KD-4x4CSK/KD-8x8CSK switcher via front panel buttons, Serial IR, Optical IR,

and RS-232 control.

Operation

After performing the setup above, the unit is ready for operation. There are several options for
controlling the unit. Commands can be issued via Serial IR, Optical IR, and RS-232, or by using
the front panel buttons.

› Note: Many advanced commands for setup and/or operation are available only via RS-232.

IR Emitter Control

When using an IR Emitter / IR Extender (sold separately), the IR Emitter must be mounted over the
IR Sensor on the front of the

KD-4x4CSK/KD-8x8CSK

. One end of the cable is connected to the
IR Receiver / Master Controller / IR Extender / IR Connecting Block, while the other end is mounted
over the IR Sensor of the

KD-4x4CSK/KD-8x8CSK

.

Serial IR Operation

The unit may also be controlled via the Serial IR interface, providing a hard-wired IR connectivity.
Use a 3.5mm Male Mono plug with the IR signal carried on the tip of the connector.

Audio Outputs

» Each Output Channel has

1 Analog L/R Audio Output:

3.5mm Stereo Phone Jack which provides de-embedded 2ch
Analog Audio Output from selected HDMI input source

» Each Output Channel has

1 Digital Audio Output:

RCA Jack which provides de-embedded Digital Audio Output
from selected HDMI input

» There are no volume or tone control features, only muting

control of the external audio outputs via RS232.

» There are no DSP features. Ie, in order to achieve 2ch analog

audio output, the selected HDMI input source audio format
must be 2ch.
