TTL Pin as Output
ATTENTION
Please note that the maximum switching current is 10 mA and the maximum
switching voltage is 3.3V per TTL output.
!
FIG. 17
If a TTL Pin is configured as an Output, the event is signalled when the volt-
age at the TTL Pin changes from 0V to +3.3V.
Under Positive edge you can select the following Function Codes:
– Fixed Low (0V): The TTL Pin is fixed to 0V.
– Fixed High (3.3V): The TTL Pin is fixed to +3.3V.
– Connection State: Via this function you can signal the connection state.
Please select the desired connection state under Connection State. The
following options are available:
– Disconnect
– Connect
– System Alarm Pending: This function signals a pending system alarm
(see CHAPTER 4.9.1).
