8.4 Command set
HR n Select “Remote“ mode
n: 0 = off
1 = on
The command HR1 sets the analyzer to Remote mode, in-
dicated by the appearance of “R” in the upper right cor-
ner of the display. In this mode the keypad on the instru-
ment front panel is disabled. Some simple status informa-
tion is still available, however control signals must be sent
via the RS-232 interface. To return the instrument to local
mode (i.e. complete control via the keypad) the command
HR0 must be sent via the RS-232 interface.
On power-up the analyzer always automatically enters
local mode.
a) “Set“ commands
The instrument only accepts “Set” commands when in ”Remote“ mode (se-
lectable with HR1). If the instrument is in ”Local“ mode an error message
is returned.
In ”Remote“ mode the analyzer is controlled by the PC.
In “Local“ mode the analyzer is controlled by the keypad.
