Operation

The equalization and gain can be controlled from two potentiometers.

The status of the module can be monitored in three ways.

1. GYDA System Controller (optional)

2. GPI at the connector module

3.

LED’s at the front edge of the module

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. The functions of the GPI and the LED are described in sections 5.1 and 5.2. The
GYDA controller is described in a separate user manual.

4.1 GPI ALARM

– Module Status Outputs

Only available when using the standard

–C1 backplane

These outputs can be used for wiring up alarms for third party control systems. The GPI
outputs are open collector output, sinking to ground when an alarm is triggered. The GPI
connector is shown in figure 4.

Electrical Maximums for GPI outputs

Max current: 100mA

Max voltage: 30V

4.2 Front Panel - Status Monitoring and Signal Detection

The status of the module can be monitored visually at the front of the front of the module.

The DA-VAEQ-6 has one LED showing the status. The hardware revision 2 of the DA-
VAEQ-6 has also a built in detector for signal monitoring. When signal is present, LED is
green, otherwise it will be red. The LEDs are described in the following table:
