Rack Controller
The RFR 5041 is supplied with a integrated LAN rack controller, which when used with
the included LYNX Desktop Controller software application provides remote control,
status monitoring and alarm logging functionality. The 1RU rack can also be fully
integrated into larger systems which are using the LYNX Desktop Controller for
centralized control of a number of LYNX systems.
The rack controller is a fixed position in the rack, located above one of the available card
slots (the lower area of this slot can still be used for a LYNX module, no capacity is
removed). The controller can be removed if required for maintenance, simply slide
forward to unplug the module. Four LEDs are provided on the module edge which are
used to indicate status.
