Only bought it a month or so ago. Not sure how to return it for warranty. Sent an email to PMDX with no response.

Parallel Port breakout boards, motherboards, and dedicated accessories / Re: Outputs Enabled Light

« on: April 01, 2023, 03:14:22 PM »

I went through the quick start procedure with nothing connected but the AC. Checking all the jumpers I found that J4 was in the "ON" position; I set it to "OFF". On power up the EStop comes on then off as it should (I left the factory jumper across the EStop pins). The power light stays on as it should.The status light blinks with the EStop light. The outputs enabled light does not turn on.

Your suggested tests:
1. I don't have a 5V LED but a voltmeter measures 0.48 DCV  between pins 2 & 6 on J7.
2. With the suggested configuration, the K2 relay does not activate when the test button is pushed.

What is the next step? Can I return the board for repair/replacement?

I just replace a PMDX 125 with a PMDX 126. On the old board the outputs enabled light was on but the outputs  were not functioning (no motor or relay movement). With the new board the power light is on but the outputs enabled light is off. I'm using an externally mounted and powered ESS Smoothstepper and Mach 4.

With my mounting configuration it's hard for me to see the J3 jumper. Does it Come shipped with the J3 on or off?

What else should I look for?

The system was running perfectly with the old PMDX until it wasn't; so my hardware and software configuration should be good.
