The following new features have been added to both
the KD-MSWCAT8x8 and KD-MSWCAT4x4 products:
Key Features
»Allows the use of either KD-VACRX or KD-CVARX receive Baluns
»KD-CVARX can be used with a Digital or Analog Audio Input (Analog Output only)
»Can now route IR signals when in Component mode via unused “H” (Horizontal sync)
signal path
Key Benefits
»Can mix both KD-VACRX and KD-CVARX Baluns on single unit
»Control display or other local (room) components by sending IR through KD-VACRX and
KD-CVARX Baluns
»Allows use of KD-CVARX Baluns when Digital Audio and RS232 Output isn’t required
Additional Key Features
»Front panel LED input/output assignment confirmation
»Easily controlled via IR Remote (included) with discrete codes, Serial IR, and RS-232
»Slim 1U Rack chassis for space conservation
RS232 Commands:
The following new RS232 commands have been added to provide control for the new features:
½‘SPCVTx’ - Video Type command: where x = 0 or 1 (0 = Component, 1 = RGBHV)
»Note: default is component.
»This command determines whether unit will switch Component or RGBHV signals.
»Example: To switch the unit from Component to RGBHV mode, enter the command;
‘SPCVT1’
»(Please note that a system reboot is required after a ‘Video Type’ switch for the settings to
take effect)
½‘SPOxxSRyy’ – IR Switching command: where xx = Output number, yy = Input number.
»This command directs the IR path from your chosen input to your chosen output
independent of your A/V routing.
»Example: to direct the IR path from input 4 to output 2, issue the command: ‘SPO02SR04’
»NOTE: for expansion configurations, total number of inputs will be limited to 8
(or 4 for KD-MSWCAT4x4
»The default assignments for IR routing are Input 1 to Output 1, Input 2 to Output 2 etc.
½‘SP C C5T hh’ - CAT5 Output Type Mask: where hh = hex value for selecting which outputs will
have KD-VACRX Balun and which will have KD-CVARX Baluns (0-VAC, 1-CVA) ‘0’ is the default
setting
»This command tells the unit which type of Balun is connected to each output number. A
selected output will choose the KD-CVARX Balun; an unselected output chooses the KD-
VACRX Balun (default).

Page 1
»See the hex value/binary number conversion table to generate the proper number to enter
for this value.(pg. 4)
»The status display through RS-232 has been updated to reflect the changes.
»Output:
»01 : Video= 01, Audio= 01, IR= 01 : Active : Mute Interval= 00
Balun= VAC : V= 50 B= 20 L= 12 M= 12 T= 12 LP= 00
»02 : Video= 02, Audio= 02, IR= 02 : Active : Mute Interval= 00
Balun= VAC : V= 50 B= 20 L= 12 M= 12 T= 12 LP= 00

IR routing through KD-MSWCAT8X8 / 4X4:
In order to send IR signals through the KD-MSWCAT8X8/4X4, you will need to follow the
configuration described below.
½To input IR signals, you will need to convert your powered IR distributions
output to an RCA type connector. Typically you can use a mono 3.5mm jack
to RCA adapter (as shown).
½Using a standard RCA male to male cable, connect this RCA to the unused ‘H’ or Horizontal
Sync input going into the switch. The supplied breakout cable is used for Component signals
and has 3 RCA connections. You will need a 5 RCA to VGA (Part number KD-VACBL not
included) breakout connector for both Switch and Balun. (Total of 2 per signal, see complete
parts list below).
½NOTE: When using the KD-CVARX Baluns, you will need to supply a female
to female HD15 gender changer to connect the Balun to the breakout cable
(KD-VACBL) this changer is not needed for the KD-VACRX Baluns.
½At the Balun side, plug an RCA to 3.5mm female mono jack adapter into the
unused ‘H’ or Horizontal output coming off the HD15 to 5 RCA breakout cable from the Balun.
You may plug your emitter directly into this adapter which can then be placed onto your display
or any other device you wish to control. You may repeat this for each IR signal you wish to route
through the KD-MSWCAT8X8/4X4.

Audio Connections
The KD-MSWCAT4x4 / 8x8 has Two (2) 3.5mm audio input connections for each video input. For
standard Analog Stereo sources, utilize the left input. For Digital PCM sources utilize the right input.
For Balanced Analog sources, utilize both inputs. Pin outs for these connections are shown below.

Balanced Analog Audio connections:
Normally an unbalanced audio connection is utilized for standard source equipment. If you wish to
use a balanced signal., the KD-MSWCAT8x8 has two (2) 3.5mm stereo audio input jacks for each
video input and is capable of transmitting a balanced signal across the 2 audio inputs by wiring
each connection as shown:. Note that the balanced audio signal will only be available when using
the KD-VACRX Baluns.
