4.4.2 Connecting an additional stirrer or titration stand
In addition to the built-in stirrer connector for the propeller stirrer 802 Stir-
rer, you can use the magnetic stirrers 801 Stirrer, 803 Ti Stand or the 804
Ti Stand with the propeller stirrer 802 Stirrer.
Proceed as follows:
1 Switch off the Ti-Touch.
2 Connect the connection cable of the magnetic stirrer or of the titra-
tion stand to MSB 2 (2-7) on the rear of the Ti-Touch.
3 Connect the propeller stirrer, if desired, to the stirrer connector of
the titration stand.
4 Switch on the Ti-Touch.
4.4.3 Connecting a Remote Box
Instruments that are controlled via remote lines and/or which send control
signals via remote lines can be connected using 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 brief
(> 200 ms) electrical pulses which display the operational state 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 sys-
tem. No exchange of data is possible, however.
Proceed as follows:
1 Switch off the Ti-Touch.
2 Connect the Remote Box connection cable to an MSB connector
(2-7) on the rear side of the Ti-Touch.
3 Switch on the Ti-Touch.
You can connect an 869 Compact Sample Changer. The Remote Box also
has an MSB socket at which a further MSB device, e.g. a dosing device,
can be connected.
