CAUTION
The Touch Control must be shut down properly by deactivation with
the power switch on the rear of the instrument before the power supply is interrupted. If this is not done, then there is a danger of data loss.
Because of the fact that the power supply for the Touch Control is provided through the Titrando, you must never disconnect the Titrando
from the power supply (e.g. by deactivating with a connector strip)
before you have deactivated the Touch Control.
If you would prefer not to position the Touch Control directly next to the
Titrando, then you can lengthen the connection with the 6.2151.010
cable. The maximum connection length permitted is 5 m.
3.2.1.2
Connecting a computer
The 851 Titrando requires a USB connection to a computer in order to be
able to be controlled by a PC software. Using a 6.2151.000 controller
cable, the instrument can be connected directly, either to a USB socket on
a computer, to a connected USB hub or to a different Metrohm control
device.
You need administrator rights for the installation of driver software and
control software on your computer.

3.3 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 controlled simultaneously by the respective control device. In addition to the
connection cable, stirrers and the Remote Box are each equipped with
their own MSB socket for this purpose.
3 Installation
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.

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 in MSB instruments. When it
is switched on, the control device automatically recognizes which
device is connected to 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 maximum connection length permitted is 15 m.
3.3.1 Connecting a dosing device
Four dosing devices can be connected to the instrument (MSB 1 to MSB
4).
The types of dosing devices that are supported are:
￭ 800 Dosino

3.3.3 Connecting a Remote Box
Instruments that are controlled via remote lines and/or that send control
signals via remote lines can be connected via the 6.2148.010 Remote Box.
In addition to Metrohm, other instrument manufacturers also use similar
connectors that make it possible to connect different instruments
together. These interfaces are also frequently given the designations "TTL
Logic", "I/O Control" or "Relay Control" and generally have a signal level
of 5 volts.
Control signals are understood to be electrical line statuses or electrical
pulses (> 200 ms) which display the operating status of an instrument or
which trigger or report an event. Sequences on a variety of instruments
can thus be coordinated in a single complex automation system. No
exchange of data is possible, however.
Proceed as follows:

You can, for example, connect an 849 Level Control (fill level monitoring
in a canister) or a 731 Relay Box (switch box for 230/110 volt alternating
current sockets and low-voltage direct current outlets). The Remote Box
also has an MSB socket at which a further MSB device, e.g. a dosing
device or a stirrer, can be connected.
You will find precise information concerning the pin assignment of the
