RS-232 Command Hints and Tips
Leading zeros may be included or omitted from command parameters.
Example: ‘
>TC=009’ Selects channel 9 as A/V output, same as ‘>TC=9’.
Multiple commands may be concatenated as single strings up to 120
ASCII
characters long.
Example: ‘
>XXTC=9’ Selects Mute A/V off, channel 9.
Example: ‘
>S0=0S4=0’ Selects
CATV
mode, no front panel lockout.
Mute A/V Off command is not required in any command; however it may be useful to send Mute A/V Off in case
Mute A/V had been set On from the front panel.
Sending all
3
status request commands to the
232-MCT
back-to-back for a full status update is allowed.
Example: ‘
>STSVSS’ Returns all
3
response strings back-to-back.
The carriage return line feed at the end of each 232-MCT response allows for easy monitoring of responses with
an ASCII terminal program. You may use ASCII CR, Hex $0D, or keyboard ‘Enter’ in programming.
You don’t have to use the ‘=’ character between the command and parameter – the string works either way.
