Secure the rack ears to each side of the KD-4x4CSA/KD-8x8CSA with the supplied hardware and then fasten the unit to the rack rails with the included machine screws.

Step 1: Find a safe and convenient location to mount or place KD-4x4CSA/KD-8x8CSA unit.

Step 2: Begin with the KD-4x4CSA/KD-8x8CSA unit and all input/output devices turned off with power cables removed.

Step 3: Connect your HDMI sources to the input ports of KD-4x4CSA/KD-8x8CSA unit.

Step 4: Connect your HDMI displays to the output ports of KD-4x4CSA/KD-8x8CSA unit.

Step 5: Before connecting power supply to power outlet, screw-in the power supply to the KD-4x4CSA/KD-8x8CSA unit.

Step 6: After all connections are made, plug-in power supply to power outlet.

Step 7: Power on input/output devices.

Step 8: Operate the KD-4x4CSA/KD-8x8CSA switcher via front panel buttons, Serial IR, Optical IR, RS-232, and TCP/IP Control.

Before permanently securing the unit for final installation, test for proper operation of the unit and cables in your system. It is recommended that you leave enough ventilation space to provide sufficient airflow and cooling.

The KD-4x4CSA/KD-8x8CSA unit may be controlled via the push buttons on the front of the unit. Choose which output to change and then select the desired input by pressing the corresponding “Input Select” button. The front LED indicators (1, 2, 3, 4/5, 6, 7, 8) correspond to the input that has been selected for each output.

The KD-4x4CSA/KD-8x8CSA unit may also be operated using the IR Remote provided with the unit. The KD-4x4CSA/KD-8x8CSA switcher features an IR sensor on the front of the unit for reception of signals.

The IR Sensor on the front panel may also accept signals from a Compass Control Master Controller or from a 3rd party control system. When using a Master Controller or 3rd party control system, the IR Emitter must be mounted over the IR Sensor on the front of the KD-4x4CSA/KD-8x8CSA unit. The other end of the cable is connected to the Multi-function I/O port on the Master Controller or the IR Extender/IR Connecting Block of the 3rd party control system.

The KD-4x4CSA/KD-8x8CSA features a 6-Pin Terminal Block for IR and RS-232 Control. Signals may be received from these connections as well as the Ethernet Jack for TCP/IP Control.

For Serial IR, connect a mono cable to the Multi-function I/O port on the Master Controller or the IR Extender/IR Connecting Block of the 3rd party control system. The other end would then connect to Pins 1 and 2 on the 6-Pin Terminal Block. IR In is Pin 1; Ground is Pin 2.

For Serial RS-232, connect a stereo cable to the Multi-function I/O port on the Compass Control Master Controller or the RS-232 port of the 3rd party control system. The other end would then connect to Pins 3,4,5,6 on the 6-Pin Terminal Block. Tx Data is Pin 3; Rx Data is Pin 5; Ground is Pin 4 and/or Pin 6. Either ground pin may be used for RS-232.

For TCP/IP control, connect an Ethernet cable from the KD-4x4CSA/KD-8x8CSA to a network router or connect a crossover cable from the KD-4x4CSA/KD-8x8CSA directly to a PC.

All connections to the KD-4x4CSA/KD-8x8CSA are found on the rear panel of the units.

HDMI Inputs:

The HDMI Inputs are located on the bottom left side of the back panel. The Inputs have a blue LED that will illuminate solid during active link (voltage + data link).

HDMI Outputs:

The HDMI Outputs are located on the bottom right side of the back panel. The Outputs have a blue LED that will illuminate solid during active link (voltage + data link).

Ethernet Jack, Serial IR, RS-232, and Power Block:

Located on the right side of the back panel.

Each Output Channel has 1 Analog L/R Balanced/Unbalanced connection: 6-Pin Terminal Block which provides de-embedded 2ch Balanced Analog Audio Output from selected HDMI input source.

The Pin assignment for the audio is as follows:

Left + is Pin 1; Left – is Pin 3; Left Ground is Pin 2.

Right + is Pin 4; Right – is Pin 6; Right Ground is Pin 5.

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 and TCP/IP.

There are no DSP features. Audio must be configured in the source. For example, in order to achieve 2ch analog audio output, the selected HDMI input source audio format must be 2ch.

Audio Output Signal Format Table:

Audio Input Signal Format | Audio L/R Output | Digital Audio Output (Coax and Optical)

————————-|——————|————————————

2ch PCM | Pass-Through | Pass-Though

Multi-Channel PCM | MUTE | MUTE

Dolby DTS | MUTE | Pass-Though

HD Audio | MUTE | MUTE

There are 4/8 Output buttons along the front panel.

Pressing an output button will select the next HDMI input.

A blue LED will indicate which Input has been selected for each Output.

Front button control can be disabled/enabled via serial control if desired.

The Optical IR window is located on the right side of the front panel receives IR remote control signals.

Front LEDs will scroll during boot up.

Video OFF setting for an output is represented by a steady blinking of the selected input indicator LED for the respective output.
