Selenio X100
Installation and Operation Manual

The X100 only uses word number 30 for the transmission of the eight GPI trigger bits.
When a trigger condition is detected, the corresponding trigger bit ( Q1 - Q8 ) is set high;
otherwise it is set low. The trigger condition is dependent on the GPI trigger type that you
set. For example, if the
Trigger is set to RisingEdge , only a rising edge detected at a
certain time (for example, at the start of a video frame) will be considered a valid trigger. Or
if the
Trigger is set to Active High , a high level GPI signal will be considered as a valid
trigger.
The mappings of the GPI input/output ports to BT-1685 trigger bits are the following:

BT-1685 Insertion Setup Example
This example involves inserting BT-1685 packets on line 12 of 1080i59 video using GPI
triggers.
1 First configure each GPI input to Rising Edge for BT-1685 triggers:
a Go to GPI and Rules Engine > GPI > GPI Direction and set all 8 GPIO Direction
options to Input.
b At GPI and Rules Engine > GPI > GPI Input , set the following for each GPI Input To
