Digital Trigger Connections

You can configure the PCIE-1802 to trigger in response to digital signals on DTRG0
or DTRG1 pin of the HDMI connector, located on the device front panel. The trigger
circuit can respond either to a rising or a falling edge. The trigger signal must comply
to 3.3 V or 5 V TTL voltage levels.
A diagram showing the DRTG input configuration of the PCIE-1802 is shown below
with a signal source.
