3.4.3 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 electrical
pulses (> 200 ms) 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 system. No
exchange of data is possible, however.
Proceed as follows:
1 Connect a 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.
