Thank you so much for the loopback idea, I think 1 goes to 5 and 2 goes to 4, yes???

We could only find two jumpers. This is a TEPRIa card and it has a top row off six LEDs where the last pix available in the manual have two rows of four LEDs. There are no jumpers where the photo shows jumpers.

If anyone has an install sheet of the new TEPRIa card with the row of 6 LEDs on top, could you please contact me or send an email with a .pdf?

Thanks, I will try the loopback ASAP.
