Remote Control
You may control the KD-4X4XC switching commands by using the
supplied IR Remote control. There are 4 groups of controls, one
group for each Output. Each Input can be selected by pressing the
Input numbers 1-4.
IR Extender:
You may want to use an IR extender, such as the KD-IRKIT300:
Front and Rear panel sensors are available for use with the IR
extender. A wired IR serial connector is also provided at the rear of
the unit.
Wired IR Extender KD-IRB3099 Unit included in the KD-IRKIT300
uses a 3.5mm male-to-male Mono cable.
RS-232 Commands:

System Commands:
Video Switch:
»
‘SP O xx SI yy’
To switch the desired Video Input to the desired Output:
»
Where xx = the Output number [01-04] –OR- [A] for ‘All’
»
Where yy = the Input number [01-04] –OR- [U, D] for ‘Up’,’ Down’ respectively.
»
‘U/D’ will increase/decrease the input number from its current position.
»
This command will switch Inputs to your desired Output.
»
Example:
To switch Input 3 to Output 1, issue the command;
‘SPO01SI03’
»
Example:
To incrementally switch the Input Up from its present number for Output 1, issue
the command:
‘SPO01SIU’
»
Example:
To switch All Outputs to Input 3, issue the command:
‘SPOASI03’
IR Routing:
»
‘SP O xx SR yy’
To route Serial IR signals
»
Where xx = Output numbers [01-04] –OR- [A] for ‘All’ Outputs
»
Where yy = Serial IR Input numbers [01-04] or [U, D] for ‘Up’,’ Down’ respectively. ‘U/D’ will
increase or decrease the IR input number from its current position.
»
This command will rout the selected Serial IR Input number [1-4] to the desired Output
number over the CAT5e/6 connection.
»
Example:
‘SPOASR02’
: Will carry IR from IR Input port 2, to ‘All’ Outputs.
‘SPO02SR01’
: Will carry IR from IR Input port 1 to Output 2.
EDID Copy and Default EDID Library:
»
‘SP C EDID xx H/C/D yy’:
To Copy EDID to Input from Output via HDMI or CAT5e/6, or from
a Default Library
»
Where xx = Input numbers [01=04] –OR- [A] for ‘All’ Inputs
»
Where H = EDID Copy from HDMI Output
»
Where C = EDID Copy from CAT5e/6 Output
»
Where D = Default EDID Library selection (see list below)
»
Where yy = Output numbers [01-04] when ‘H or ‘C’ variables are selected
–OR-
Default EDID library settings [01-08] when ‘D’ variable is selected.
»
This command will either copy the EDID information from a selected Output to a specific
Input (or All Inputs), or, write EDID information from an internal library of default EDID settings
to a specific Input (or All Inputs).
»
Example:
To copy the EDID information from HDMI Output 2 to Input 4, issue the command:
‘SPCEDID04H02’
