6.1 RS232 interfaces
The 732 IC Detector has two RS232 interfaces 1515 and 1616 (see Fig. 3)
which have the same features (see section 6.1.7 – 6.1.9), but can be
used differently.
RS232 interface 1616 is reserved for the connection of a PC or a printer
(see section 2.9.4 – 2.9.5) and allows remote operation of the 732 IC
Detector 732 and 733 Separation Center 733 by an attached PC (see
section 6.1.1 – 6.1.6).
RS232 interface 1515 is normally used for the attachment of a 709 IC
Pump, but a printer can also be connected in place of the pump (see
section 2.9.6).
6.1.1 General rules for remote control
The 732 IC Detector is equipped with the comprehensive Metrohm re-
mote control language, which allows full control over the instrument via
an RS232 interface, i.e. the IC Detector can receive data from an exter-
nal device or send data to an external device. The 732 IC Detector
sends 2×C
RR
and L
F F
as the terminator of a requested data block. In
contrast, C
RR
and L
FF
are used as the terminator of a data line. On re-
ceipt of data from an external device, this must always close its com-
mands with C
RR
and L
FF
. If more than one command is sent on a line, ‘;’
must be used as a delimiter between the individual commands.
The data are grouped logically and readily understandable. For exam-
ple, to select the dialog language the command
&Config.Aux.Dialog"english"
must be sent with entry of the boldface characters sufficing, in other
words
&C.A.D"english"
All quantities of the 732 IC Detectors are collected in groups. The en-
tries for the configuration, for example, are located in the group
&Config
The ‘Config’ group contains sub-groups, e.g. for setting the RS232 in-
terface parameters
&Config.RSset
or for various settings
&Config.Aux
The data have a hierarchical structure (tree structure). The quantities
which appear in this tree are called objects in what follows. The dialog
language is that object which is called up with the command
