TTL-Pin as Output
FIG. 25 TTL-PIN AS OUTPUT
If a TTL-Pin is configured as Output, the event is signalised as change of volt-
age on the TTL-Pin from 0V to+5V.
Under Positive edge you can select one of the following Function Codes:
– Fixed to Low (0V): The TTL-Pin is set to 0V permanently.
– Fixed to High (5V): The TTL-Pin is set to +5V permanently.
– Connection Status: Via this function you can signalise the connection sta-
tus of a line. Select the connection status under Status. The following con-
figurations are possible:
– Disconnect
– Calling
– Incoming call
– Connect
Under Line (only in the ISDN operating mode) you select the line whose
status you want to signalise. In addition to Line 1 and Line 2 you can mon-
itor the connection status of both lines if you select the option All Lines.
As soon as one of the two lines meets the criteria, the signal is set on the
TTL-Pin.
ATTENTION Please pay attention to the maximum switch current of 10 mA respectively
the maximum switch voltage of 5V per TTL output.
