3.14.3 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.
