1 Module VM
1.1 Description
This module distributes and amplifies one continuous wave input (10 MHz) to six outputs. A
seventh spare output stage together with a change-over relay at each of the six outputs
enables completely redundant output signals. Each output stage is monitored for signal
failures. Alarm outputs are available as SNMP traps, GPI OUT, LEDs and lamps.
A PC or the RUB IE module is required for the configuration of this module.
The front panel label VM visibly identifies where each module is located. The serial number is
located on the bottom side of the lower circuit board of each module.
The standard hardware of this module has all of the following key features:
•“Hot Swapping“, i.e. it is possible to insert or remove a module without interrupting the
operation of other modules in this frame.
•Failure relay, connected to the FAIL_A and FAIL_B pins of the RLC connector at the rear of
the frame.
•RS232 and TC_link (RLC connector) interfaces to have access to the internal bus of the
chassis.
•Four programmable function keys, lamps and LEDs on the front panel (RUB1 version only).
•Flash memory containing the firmware, so configuration and updates are possible via a
PC connection. You can download the latest version of the program from:

•One continuous wave input.
•Six independent continuous wave outputs plus one spare output, individually monitored.
•Changeover relays enable completely redundant output signals.
•Alarm outputs indicating failures and warnings: Lamps and LEDs (RUB1 version only), GPI
OUTs and SNMP traps.
