Remote Monitoring (RM) and Service Channel (SC)
RM with analog interface
The Remote Monitoring function (RM) offers the option of accessing equipment data at the
SWT 3000 and PowerLink units via a serial interface with the service PC. With RM it is possible to
transmit equipment data between the terminals of one or more transmission routes. Transmission
is possible in both directions.

The event memory of the unit can, for example, be read out at station 2 with a service PC in sta-
tion 1 by means of RM.
For this purpose the units are assigned an RM address. A master - slave connection must also be
configured.
RM communication over several transmission routes is also possible by connecting two units via
the back RM interface (SSB).
