Module status
The status of the module can be monitored in three ways.
1. Multicon Gyda System Controller (optional).
2. GPI at the rear of the sub-rack.
3. LED’s at the front of the sub-rack.
Of these three, the GPI and
the LED’s are mounted on the module itself, whereas the GYDA
System Controller is a separate module giving detailed information on the card status.

These outputs can be used for wiring up alarms for third party control systems. The GPI
outputs are open collector outputs, sinking to ground when an alarm is triggered. The GPI
connector is shown in figures below.
Electrical Maximums for GPI outputs
