4.2 GPI alarms
The GPI alarms of the PGM-HD-2X1-PB are fully compatible with the HD-SDI-CHO-
2x1 module
, and thereby also the “change-over mode” of the FRS-HD-CHO (FRS-HD-
CHO can also be configured to be compatible with the FRS-HD-DMUX module). See
the table in the next sub-chapter for a detailed description.
4.2.1 Functions of 8pin modular jack
GPI name Function Pin # Mode Direction
Status General error status for the
module. Pin 1 Inverted Open
Collector
(open is alarm) Output
LOS 1 Loss of signal or lock at
selected input Pin 2 Open Collector Output
Input 1 selected Input 1 selected (IN1) Pin 3 Open Collector Output
Input 2 selected Input 2 selected (IN2) Pin 4 Open Collector Output
Select input 1 Fade in input 1, after fade out
of input 2. Activating
simultaneously as pin 6 will
give fade to black. Pin 5 TTL, 0V = active
level Input
Select input 2 Fade in input 2, after fade out
of input 1. Activating
simultaneously as pin 5 will
give fade to black. Pin 6 TTL, 0V = active
level Input
Input 2 selected Connected to pin 4 on
backplane Pin 7 Open Collector output
Ground 0 volt pin Pin 8 0V.
