I only quoted what he had posted.eng199 wrote: ↑Mon Feb 05, 2018 2:01 pm Let me try to clarify the instructions:
See if the 5V regulator is working:
*Locate D2 pin 2. See the photograph on page 2 in the document linked to this post: viewtopic.php?f=60&t=1470.
*Plug in ACORN +24VDC and COM, but nothing else
*Measure from D2 pin 2 to COM. The measurement should be 5V.
There is no need to repeat the procedure in the document.
Marty, can you say with any confidence that "D2=0V" was the result of the procedure given previously? Troubleshooting on speculation is not productive.
transmon is getting an RMA to return his ACORN, so he may not even return to this thread.
My apologies Matt.
I will let you handle these things.
