Setting the remote lines
= start instrument 1
= start Dosimat on instrument 1
= stop instrument 1
= start Coulometer 737
= simulate <ENTER> key
= initialize remote interface
arbitrary 14 bit pattern
The CTL:Rm command controls external instruments via the remote inter-
face. It causes the setting of defined line states or the sending of pulses via
the 14 remote output lines.
Predefined bit patterns are supported which can be selected by short
names (for example, "START device1" or "ENTER").
"START device1" starts the operating mode set for a connected Metrohm
instrument. "START dosX" starts a Dosimat which is connected to a
Metrohm titration instrument via the “activate” line (special Metrohm cable
required). "ENTER" simulates pressing of the <ENTER>key of a Coumeter
or Titrino. "INIT" resets all output lines of the Remote socket to 0 (zero).
Setting particular bit patterns allows flexible control of connected instru-
ments.
Here the following is valid: 0 = line inactive
1 = line active
* = do not change line state
Example:
*************1 = Output line 0 active = start device1
Further details about the remote interface are found on page 96ff.

10 CTL:RS
RS
Clear value: &M;$
14 ASCII characters
Data communication via the
serial RS 232 interface
= start instrument in current mode
arbitrary string of 14 characters
Data (=character string) can be sent to instruments connected via the se-
rial RS interface.
Make sure that the transmission parameters of the RS 232 interface are in
corespond to those of the connected instrument (see Configuration Menu
'>RS232 settings', page 66).
Any letters, numbers and special characters can be chosen from the char-
acter set of the instrument.
