I have an Ethernet Smooth Stepper (ESS) with an MB3 BOB and wanted to add torch height control to my plasma setup.  I purchased a HYD XPTHC 4H because it seemed like it had many useful features.  Well the horrible instructions for connecting to a CNC have left me scratching my head really bad.  I can get the torch to fire and cut but no matter what I try I cannot get the UP/DOWN outputs to feed any signal to the ESS.  Has anyone had any luck setting this device up?

The pin connections to ESS/MB3 are:

1 AUTO - Not Sure what it does and not connected

2 UP Up signal, Active low - No signal ever gets output connected to input X210 on MV3 BOB

3 DOWN Down signal, Active low - No signal ever gets output connected to input X211 on MV3 BOB

4 ARC ON with IHS, Active HI connected to Output Y314 on MV3 BOB - This works

5 EX ARC ON Arc start without IHS, Not connected seems its the same as pin4 but without THC

6 ARC Feedback - connected to input X211 on MV3 BOB (ARC OK signal works)

7 COLLISION output - Not using but it works when the probe activates

8 Control COM Isolation Control COM - Connected as common

If anyone has any solutions on how to make it work to send up and down signals to the ESS/MB3 that would be appreciated.  I have spent hours with different settings in the control module to no avail.
