Main board startup test

Post by jbmeng »

Sorry about the preview, I accidentally submitted before I was finished.
I followed the directions for testing the Main board (109-15000-000-E2) at Step 1 before any assembly.
After applying 9 V battery at the input, I did get the screen boot-up indication and then the expected resultant display as indicated in the User Manual diagram.
I noted 2 flashes on the LED but then after a few seconds, but then the LED continued to flash at a higher rate. This later flashing was not mentioned in the user manual.
Is this continued LED flashing normal and correct? Should I continue assembly?

Vbat = 9.11 V
V+ = 8.35
TP8 = 3.31 V

The high rate LED flashing is normal. It indicates trigger activity.
