3.8 Connecting MSB devices
In order to connect MSB devices, e.g.stirrers or dosing devices, Metrohm
instruments are equipped with up a maximum of four connectors at 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 controlled simultane-
ously 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 illustration provides an overview of the devices that can be
connected to an MSB socket, along with a number of different cabling
variations.
The question of which peripheral devices are supported depends on the
control instrument.
Note
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.
￭ Type 700 Dosino and 685 Dosimat dosing devices cannot be con-
nected together with other MSB instruments on a shared connector.
These dosing devices must be connected separately.
Caution
Exit the control software before you plug MSB instruments in. The con-
trol instrument recognizes when it is switched on which instrument is
connected at which MSB connector. The operating unit or the control
software enters the connected MSB devices into the system configura-
tion (Device manager).
MSB connections can be extended with the 6.2151.010 cable. The length
of the connection must not exceed a maximum of 15 m.
