RS232 Command Protocol
CPU controller commands supported by the unit are defined below. All commands must be terminated with a <CR> (carriage
return). When a command is sent, the entire string is echoed back along with a response from the addressed unit as shown in the
Command Definitions table (below). All characters in the command string are case sensitive (see Command Definitions table),
and all numbers below 10 must have a leading 0 (ex: 1 = 01).

If the first field is not a known command (as listed above) or SW field is different from the serial address programmed in the switch
memory, the command will be ignored. If the SW field corresponds to the unit address, but the syntax is wrong after this field, the
switch will answer with a bad response ?<CR>.
Examples:

Type, then
press <Enter>
Action
RU 01
This will return the unit size. RU must be in upper case. There is a space (press the <Spacebar>) between RU
and 01. 01 is the default serial address of the unit.
CS 01,02,01
This will connect input 2 to output 1. The first 01 is unit serial address; 02 is input 2; the last 01 means output
1. (There is only 1 output, so this value will always be 01). There is a space between letters and numbers,
but a comma between just number values.
CM 01,03,01
This will change output mode to PIP. The first 01 is the serial address. Change as needed for the SPLITMUX
you are controlling. 03 is the mode setting desired (PIP). The second 01 means output 1.
CF 01
This will bring up the Text Menu for the SPLITMUX with serial address 01. Text menu functions begin on
page 41.
