Parallel Port breakout boards, motherboards, and dedicated accessories / PMDX-126 & UC400ETH Compatibility

« on: June 20, 2016, 01:48:14 PM »

Hi there,

I'm currently running Mach3, but am interested in trying out the UCCNC software to run my CNC router. I currently have a PMDX-126, PMDX-134 w/ Gecko G203V drives, a PMDX-107 spindle controller card, and an Ethernet SmoothStepper.

UCCNC requires use of one of their motion controllers to interface with the software. I'm interested in the UC400ETH, as the computer running my CNC is more modern and is running 64bit software, so it has no parallel port driver. Currently I'm using the Ethernet SmoothStepper, but would like to swap it out for the UC400ETH as it is compatible with UCCNC as well as Mach3, just in case.

Would this board be an easy swap with the Ethernet SmoothStepper I have connected to my PMDX-126? From reading the documentation it looks like the pinouts for the 26pin connectors are the same between the Ethernet SmoothStepper and UC400ETH. I'm just curious how things will interface on the PMDX side of things. Here's a link to a thread on CNC Zone where a user mentions having to make custom crossover cables to get things to work correctly:

Here's a link to the UC400ETH documentation:

And here's a link to the Ethernet SmoothStepper documentation:

Any help or guidance is greatly appreciated. Thanks!
