ESSAGES
Device messages (to IEC 625-1) are transmitted on the data lines, in which case the
ATN line is not active, i.e. high. The ASCII code (ISO 7-bit code) is used.
Commands Received by the Amplifier in Listener Mode
(Controller to Device Messages)
The ASCII code (ISO 7-bit code) is used. All commands to the amplifier
consist of a single character set followed by the "Line feed" character
(hexadecimal: 0A; decimal: 10) as a terminator.
All commands to the amplifier must be terminated by a terminator. The only
permissible terminator is:
<Line feed> (ASCII code 10 decimal)
A command line may require more than one line on the screen of the
controller because it is only limited by the terminator. Most controllers
automatically append a terminator to the transmitted data.
