any binary pattern with 14 bit
The CTL:Rm command is used for controlling external devices via the
Remote interface. It sets defined line conditions or transmits impulses
via the 14 Remote output lines.
Predefined binary patterns are available; these can be selected via
simple names (e.g.
START device 1
or
METER Mode pH
).
START device x
starts the set mode of a connected Metrohm device.
START Dos x
starts a Dosimat which is connected with a Metrohm titra-
tor via the "activate" line (a special cable is required).
METER xxx
switches to a particular measuring mode with 691, 713, 780 pH Meters
and 692, 781 Ion Meters.
Sample ready
can be used as a continue impulse, e.g. for a connected
Titrando.
Setting special binary patterns allows the flexible monitoring of con-
nected instruments. The following applies
0 = line inactive
1 = line active
∗ = retain line condition
Example:
*************1
= Output line 0 active = start device 1
Details about the Remote interface can be found in the Technical Ref-
erence.
