5. Module status
The status of the module can be monitored in two ways.
1. GYDA System Controller (optional).
2. LED’s at the front of the sub-rack.
The LED’s are mounted on the module itself, whereas the GYDA System Controller is a separate module
which gives detailed information on the card status. The functions of the LED’s are described on the next
page. The GYDA controller is described in a separate user manual. This manual is available on our web
site: http://www.network-electronics.com/
5.1 GPI ALARM – Module Status Outputs
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 Figure 4 .
Electrical Maximums for GPI outputs
Max current: 100mA
