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:

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.
