Control Connection
An external Control Interface is provided on the
rear termination panel. When an R CT 5020 Rack
Controller (or R CT 5030 Master Controller) is fitted
to the rack this port can be used for two primary
functions:
1. When configured as a RS 232 serial port this can
be connected directly to a PC running the LYNX
control software.
2. When configured for RS 422 operation this port is
used to daisy chain other racks fitted with R CT
5020 Rack controllers (up to 15 additional racks)
Note. Please refer to the R CT 5020 Reference
Manual for details on how to re-configure the port
and more detail on the use of this control interface.
The connection is a 9 pin SubD female connector.
Function and connection information is described
below.
