Mounting
»Rack mount: Secure the rack ears to each side of the
KD-MSWCAT8X8 with the supplied hardware. Then, fasten
the unit to the rack rails with the included machine screws.
NOTE: Keep a minimum of 1RU space above and below
the unit.
Figure 1: Rack mounting the KD-MSWCAT8X8
5. Top Row – CAT5 Expansion Connections
Provides an expansion path allowing multiple KD-MSWCAT8X8 units to be daisy chained for matrix
switcher expansion.
½NOTE: DO NOT connect additional KD-VACRX or KD-VACWPRX Baluns to these
ports. They are for expansion use ONLY.
6. Power Connection
6v - 6.6A. Please use included power adapter.
You MUST use the Power Supply provided with your unit or you
VOID the Key Digital®Warranty and risk damage to your unit
and associated equipment.
7. IR eye and Serial IR port
»a. The IR eye on the rear panel is identical to that on the front of the
unit and can be used with a flasher or the supplied IR remote. It offers
a convenient way to conceal unsightly IR flashers.
»b. The serial IR port can be used with serial IR control systems
8. RS-232 Connector
This connector has two functions. It serves as a serial communication port
for connection to an RS-232 based control system and also for firmware
updates via serial connection to a standard PC.
See page 12 for RS-232 control protocol.
9. Operation Mode
This switches between the “Programming” mode (for updating the unit’s firmware)
and “Normal” operation.

3. IR Eye
The IR eye on the front panel receives commands from IR
remote controls or IR flashers. Note that an identical IR eye is
also available on the rear panel.
When IR Control is enabled, both eyes are active.
Quick Setup Guide
1. Begin with the KD-MSWCAT8X8 and all input/output devices turned off with power cables
removed
2. Connect CAT5 outputs located on the lower row of jacks to KD-VACRX or KD-VACWPRX
Baluns at display or receiving devices.
3. Connect the associated balanced/unbalanced analog or digital audio sources via the 3.5mm
stereo jack.
4. Connect video sources to appropriate input ports on the KD-MSWCAT8X8. For VGA/RGBHV
sources connect the male VGA cable directly to one of the unit’s female VGA input connectors.
For a Component/YPrPb connection, utilize the supplied break-out cable for your 3 wire RCA
connections.
5. Connect power to the KD-MSWCAT8X8 as well as all other input and outputdevices and turn
them on.
6. Operate KD-MSWCAT8X8 switcher via front panel buttons, IR remote, serial IR or RS-232
control
Operation
After performing the setup above, the unit is ready for operation.
Most applications will involve only input switching for day-to-day operation. There are several
options for controlling the unit. Commands can be issued via IR remote control, RS-232 or simply
by using the front panel buttons. See pg. 11 for IR Remote information and pg._ for RS232 control.

Troubleshooting:
Q: I am not seeing any video?
A: If connecting via Component, make sure you have connected the 3 RCA connectors correctly
at both the Input and Output sides. The KD-MSWCAT4X4/8X8 does not do any Video format
conversions so it will only output the format that is input. If you are inputting VGA you will be
outputting VGA. Make sure the Video output is not muted.
Q. I do not hear any audio?
A. The audio input takes a standard analog signal via a 3.5mm stereo audio to a 2 x RCA breakout
cable. Make sure the audio input level is not 00 and the output is not muted.
If you are using Digital audio, ensure the correct breakout cable is utilized and that you are feeding
a coaxial input. The KD-MSWCAT4X4/8x8 does not do any Audio format conversions so it will only
output the format that is input. If you are inputting PCM audio you will be outputting PCM audio
Important Product Warnings:
