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 they 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. However,
no exchange of data is possible.
Proceed as follows:
1 Connecting the Remote Box
￭
Exit the control software.
￭
Connect the Remote Box connection cable to one of the sockets
marked with
MSB
on the rear of the control instrument.
￭
Start the control software.

Connecting the Remote Box
You can connect the following instruments to the remote connector,
among others:
￭
849 Level Control (fill level monitoring in a canister)
￭
731 Relay Box (switch box for 230/110 volt alternating current sockets
and low-voltage direct current outlets)
￭
843 Pump Station (for complex sample preparations or for rinsing
external titration vessels)
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
interface on the Remote Box in the
appendix
