Metrohm 730 Sample Changer - Manuel (Page 103)

730 Sample Changer, Detailed Description 100
Predefined bit patterns are supported which can be selected by
short names (for example, "START device1" or "METER mode
pH").
"START deviceX" 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). "METER XXX" causes the 691,
713 pH Meter and 692 Ion Meter to switch to a particular measu-
ring mode.
Setting particular bit patterns allows flexible control of connected
instruments.
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 pa-
ge 119ff.

RS
Clear value: &M;$G
14 ASCII characters
Data communication via the
serial RS232 interface
= start instrument in current mode
arbitrary string of 14 characters
Data (=character string) can be sent to instruments connected via
the serial RS interface.
Make sure that the transmission parameters of the RS232 inter-
face correspond to those of the connected instrument (see Confi-
guration Menu '>RS232 Settings', page 86).
Any letters, numbers and special characters can be chosen from
the character set of the sample changer.
This function is suitable for instruments with Metrohm remote con-
trol language. These can be controlled with so-called triggers.
The most important of these are:
&M;$G Go, start instrument in current mode
&M;$S Stop, stop instrument
&M;$H Hold, interrupt method
&M;$C Continue, resume method
