Alarm Output.
When the mainframe GPI interface is enabled, you can con fi gure
the BLACK 1, BLACK 2, or BLACK 3 connector to output an alarm. When an
alarm condition is detected, the output signal from the selected connector turns off
for about 60 ms.
The AGL7 module alarm output is available only when the mainframe GPI
is enabled and the GPI ALARM OUTPUT menu item is set to Enable. (See
page 2-32,
Using the Mainframe General Purpose Interface (GPI)
.)
Changing the Input/Output Con fi guration.
The CW connector is con fi gured at the
factory to be an input for CW signals. You can recon fi gure the connector to output
a 48 kHz word clock signal by changing the position of an internal cable.
CAUTION.
To prevent damage to the mainframe and the module, be sure to
disconnect the power cord before removing the module.
To output a 48 kHz word clock signal from the CW connector:
1. Disconnect the coaxial cable from the connector labeled J040 on the
AGL7 module. (See Figure 2-6.)
2. Reconnect the cable to the connector labeled J960 on the AGL7 module.
3. Place the 48 kHz CLOCK label provided with the module on the rear panel
below the CW connector.
NOTE.
The word clock signal automatically follows the format of the
Black 1 signal.
