Bits# trigout usage

If this template helps then use it. If not then just delete and start from scratch.

OS (e.g. Win10): Enterprise version 1909
PsychoPy version (e.g. 1.84.x): 3 version 2020.2.5
Standard Standalone? (y/n) Sysytem is standalone but with the hope of sending an external synch to an FNIRS device.
**What are you trying to achieve?: I want to use trigout on the Bits# box to control fNIRS data collection onset. (BNC to BNC connection)

**What did you try to make it work?: Nothing yet because I cant find a reference to Trigout in the Psychopy forum/documentation.

I have the Bits# box working for image display and I have edited the config.xml to insert a line of code enabling trigout but I haven’t seen a way to drive that ouptut on the Bits# box in the psychopy documentation. I can see how to drive the digital output lines but hoped to use the bnc connector already available for trigout instead.
