RS-232 Command Hints and Tips
You can control a 232-Amp+ and a 232-series tuner from a single RS-232 port by daisy-chaining RS-232
between the Amp and Tuner. Set the Tuner to ID 2, the Amp will always be unit 1.
Example: ‘ >1VM2P0’ Sets the 232-Amp+ to mute, and the tuner to Off.
The carriage return line feed at the end of each 232-Amp+ 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.
Gating and Volume
If you want the 232-Amp+ to act as a straight mixer, set Mono 1 and Mono 2 Gate Threshold (4) and Gate
Hold (5) to zero (00). Note that both need to be turned off, the 232-Amp+ works best as either a fully gated
smart mixer or as a standard mixer, not both.
Usually, gating works well at the default settings, but feel free to adjust the Gate Threshold (4) and Gate Hold
(5) to work best with your application.
Try testing the system with the 232-Amp+ set higher than the default 20 dB gain (VG command). There are
slight changes in gating performance at the highest levels, but usually 26 dB offers a good blend of volume and
performance.
Cloning Amplifiers
If you are installing a number of units in the same facility, you can clone your settings using HyperTerminal,
Tera Term, or other Terminal app. Most allow you to send a text file instead of typing all the settings. Type in
the series of commands in Notepad or other text editor such as:
>VG=1
>VL=60
>V0=5,00
>V1=1,60
>V21,60 (if you want to skip the ‘=’ sign)
Once you’ve refined all the settings, just sent the file to the other 232-AMPs in the site. After that, the installer
can use a screwdriver and the DIP switches to tweak volume levels for the room.
