Alarms
GPI Out 5 and 6 (e, f) can be configured to be asserted (logic ‘L’) for a selection of
error conditions.
There are, in total, a maximum of nine separate alarms for AES audio I/O and three
for analogue audio I/O. All alarm conditions can be applied to either GPI output. The
following table lists the maximum number of alarms available. See Section 6 ‘Control
Descriptions’ for more details of alarms.

Table shows pin number (remote number)
Note
:
Remote 1 and Remote 3 are 26-way high-density D-Type female
sockets. Frame ground is pin 2 and +5V @500mA is pin 1 in each case.
Remote 2 and Remote 4 are 26-way high-density D-Type male plugs
and frame ground is pin 6 in each case and +5V @500mA is pin 15 on
Remote 2.
Note: The +5V output is protected by self-resetting thermal fuses, which
limit the total output current available from Remotes 1-4 to
approximately 1A.
