Control via RS-232 Option
Using appropriate control codes, it’s possible to switch any input to any output under
control of a computer or other hardware control device. To use this functionality, first
prepare a control cable by reference to the table below. Make certain that you have
continuity between the pins as shown.
The RS-232 control connections are as follows:
MX-5288

RS-232 transmission format:
Baud Rate: 9600 bps
Data bit: 8 Bits
Parity: None
Stop Bit: 1 bit
Flow Control: None
The RS-232 control codes used by the MX-5288 are as follows:
ASCII Code
Meaning
VR
Displays Firmware Version
INx (eg IN1)
Input 1 through 8
IN0 (Zero)
“Muted” Input
OUTx (eg OUT1)
Output 1 through 8
ALL
All Outputs
>
Routing Indicator
CODE EXAMPLES:
“IN1 > OUT3” [Route Input 1 to Output 3]
“IN1 > ALL” [Route Input 1 to ALL Outputs]
“IN0 > OUT2” [Mute Output 2]
NOTE: Full command lines must be followed by an ASCII Carriage Return[0x0D] for the command to be processed.
