13.2. Communication with a PC or a superordinated data system
If the unit is put into remote control mode, the TFT-DISPLAY will
read “R” = REMOTE.
In general, the computer (master) sends commands to the
instrument (slave). The instrument sends data (including error
messages) only when the computer sends a query.
In remote control mode, the start command and all values to be
set must be resent by the PC via the interface in case of a power
interruption.
AUTOSTART is not possible.
A transfer sequence consists of:
•
command
•
space (
⇔
; Hex: 20)
•
parameter (decimal separation with a period)
•
end of file (
↵
; Hex: 0D)
•
The response (data string) after an
in
command is always
followed by a line feed (LF, Hex: 0A).
The commands are divided into
in
or
out
commands.
in
commands: retrieve parameters
out
commands: set parameters
The
out
commands are valid only in remote control mode.
