-126 & -134 Test mode

[ks_pmdx]

I can't seem to get the test mode working with the PMDX-134 on the -126. 

Setup is:
PMDX-126
PMDX-134
Gecko 213v / gecko stepper on J1.

Anyone have a jumper suggestions or troubleshooting advise?

I think i figured it out. J1 on the PMDX-126 controls J4 on the PMDX-134.

Since I was testing one stepper hooked up at a time, it was originally wired as (I expected) J1=J1. The way the enclosure was laying on the bench, I didn't notice the activity light flashing on the drivers until I started trying the other axis.  /light bulb moment....

Now,  if this is a jumper or ribbon cable issue please let me know.

The correlation between J1 of the PMDX-126 and J4 of the PMDX-134 is
as you described it.

It is probably easier to think in terms of which DB-25 pins control which
connector on the PMDX-134.
