3.13 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 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 illustration provides an overview of the devices that can be

connected to an MSB socket, along with a number of different cabling var-

iations.

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 connec-

ted 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 control

instrument recognizes when it is switched on which instrument is con-

nected at which MSB connector. The operating unit or the control

software enters the connected MSB devices into the system configuration

(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.
