The OPTO interface inputs can be used to dynamically alter the Shark operational attributes (f.i. some RDS flags, as TA,
M/S, EMERGENCY DATASET, Split operating mode, etc) in response to logic signal transitions.
INPUT 1 may be used also for external network ‘split’ command.
INPUT 2 enabling will cause LED 2 on Front Panel to light.
INPUT 3 enabling will cause LED 3 on Front Panel to light.
The OPTO interface is installed only on Shark versions with RDS or with SPLIT option installed.
NOTE: the opto-input are not hardware assigned, but their function is ssigned from the BSN.
