Note
If an MSB stirrer is connected to the MSB1 socket, then the stirrer con-
nector at Tower 1 cannot be used, because both sockets are controlled
internally via MSB1. This also applies to the MSB2 socket and the stirrer
connector on Tower 2 for 2-tower models of USB Sample Processors.
3.21.3 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 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.
