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: „ >VXTC=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-STS 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-STS 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.
