The following instruction set is available for unit control independent from the unit
type. A additional special instruction set controls interface dependancies or is only
valid for specific options.
The power supply is switched to a „Remote-Mode“
automatically by receiving the first instruction (LED
„Remote“ glows). Subsequently the unit control is
exclusively possible via the implemented interface
instead of the front panel, till the unit is
disconnected from mains. Digital Interface I
accepts as well the Reset-instruction(*RST) for switching the power supply back to
the „Local-Mode“ (LED „Local“ glows).
Caution
Please follow the user manual of the unit as well during unit
control via the digital interface!
Optional unit function may contain additional digital interface
functions (see unit user manual “Option M: Modification”)!

The instruction sequenz comprises ASCII-characters in the following format:
[Instruction] [Space] <Parameter optional> [LF]
Instructions are written in capital letters; lower case letters are optional. Every
instruction sequenz is terminated with a LF (dec. 10); once the instruction is sent
to the interface it is executed immediately.
