TTL-Pin as Output
ATTENTION
Please pay attention to the maximum switch current of 10 mA respectively the
maximum switch voltage of 5V per TTL output.
!
FIG. 16
If a TTL-Pin is configured as Output, the event is signalised as change of voltage
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 State: Via Connection State you can signalise the connection
state of a line. The following configurations are possible:
– Disconnect
– Connect
– System Alarm Pending: If one of the possible system errors (see CHAPTER
5.7.1) occurs, it can be signalised by selecting this option.
– MPEG Encoder running: If the encoder detect no error, the TTL-Pin will be
set.
– PAD available: If the PAD insertion is activated (see CHAPTER 5.5.2.1.2,
Page 36) and the encoder receives data the TTL-Pin will be set.
