2.2.7 Connecting dosing devices and stirrers
Metrohm Sample Processors have various connections to which dosing
devices and stirrers can be connected.
Stirrers
The 722/802 Rod Stirrers and 741 Magnetic Stirrer have a DIN
connector and are connected to the rear panel of a tower (Tower stirrer
T1 and T2).
As with other Metrohm instruments, e. g. Titrandos, the three MSB
connectors (MSB = Metrohm Serial Bus) are very versatile. You can
connect an 801 Stirrer or an 804 Ti Stand to them.
Dosing devices
Up to three 700/800 Dosino or 685/805 Dosimat type dosing drives
can be operated by connecting them directly to the MSB sockets of a
Sample Processor. One 800 Dosino or 805 Dosimat can also be con-
nected to the MSB output connector of another instrument connected
to the MSB socket, such as the 801 Stirrer, in a so-called 'daisy chain'.
Please note that only one instrument of a particular type may be pre-
sent in such a daisy chain, e. g. a 801 Stirrer and a 805 Dosimat.
A 700 Dosino or a 685 Dosimat must be connected directly to the
MSB socket of the Sample Processor.

The instrument will only recognize automatically a connected dosing
device when it is switched on or after RESET.
