3.13 Connecting MSB devices
In order to connect MSB devices, e.g. stirrers or dosing devices, Metrohm
instruments are equipped with up to a maximum of four connectors on
what is referred to as the Metrohm Serial Bus (MSB). Various kinds of
peripheral devices can be connected in sequence (in series, as a
"Daisy Chain") at a single MSB connector (8-pin Mini DIN socket) and con-
trolled simultaneously by the respective control instrument. In addition to
the connection cable, stirrers and the Remote Box are each equipped with
their own MSB socket for this purpose.
The following figure provides an overview of the instruments that can be
connected to an MSB socket, along with a number of different cabling
variations.

The control instrument determines which peripheral devices are suppor-
ted.
NOTICE
When connecting MSB devices together, the following must be
observed:
■ Only one device of the same type can be used at a single MSB con-
nector at one time.
■ Dosing devices of the 700 Dosino and 685 Dosimat plus type cannot
be connected together with other MSB devices on a shared connec-
tor. These dosing devices must be connected separately.
