RS-232 Command Hints and Tips

Leading zeros may be included or omitted from command parameters.

Example:

>TC=089.5’

Selects preset 89.5 as A/V output, same as ‘>TC=89.5’.

Multiple commands may be concatenated as single strings up to 120

ASCII

characters long.

Example:

>XXTC=89.5’

Selects Mute A/V off, station 89.5.

Example:

>S0=0S4=0’

Selects odd frequency 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-STA

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 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.
