If an TTL Pin is configured as an Output, the event is signalled when the
voltage at the TTL Pin changes from 0V to +5V.
Under Positive edge you can select the following Function Codes:
– Fixed Low (0V): The TTL Pin is fixed to 0V.
– Fixed High (5V): The TTL Pin is fixed to +5V.
– PC Controlled: Special function for projects.
– Connection State: Via this function you can signal the connection state of
a line. Please select the desired connection state under Connection State.
The following options are available:
– Disconnect
– Call Out
– Call In
