GPO Switch Functions
Each GPO consists of a pair of pins, forming a switch that is CLOSED
when the output is ON, and OPEN when the output is OFF. The default
GPO function mappings are defined as follows:
GPO-3: iCap™ Server Connection
If iCap™ is active on your HD491, checking
Monitor connection on
GPO-3
on the iCap™ configuration page will cause GPO-3 to close when
your encoder has a valid connection to an iCap
™
server, and open when
iCap
™
is not connected.
GPO-4: CC1/S1 Activity
If iCap™ is active on your HD491, checking
Monitor S1 activity on
GPO-4
on the iCap™ configuration page will cause GPO-4 to close when
your encoder is receiving real-time caption data for CC1/S1 through
iCap™, and open when the iCap™ connection is idle.
Other GPOs: No functionality currently defined
