I running Mach3 with a Texas Microcircuit THC301d with a parallel cable to com port 2. Everything was working fine till my break out broad for the servos went dead. Got a new break out broad installed and got it up and running but my THC doesn't work. I think I changed a few pin numbers. I should have recorded everything. Does any one have an installation manual or the the pin numbers for the inputs and outputs used by the THC301d.

Here are the signals for the original THC-301 on Port 2. I expect that the THC-301D uses the same assignments.

E-Stop input                       Pin 10     Green check on Active Low
THC On output (torch fire)   Pin 15     Green check on Active Low
THC Up input                      Pin 12     Green Check on Active Low
THC Down input                  Pin 11     Green Check on Active Low

All of this relates to Mach3, and you have posted in the Mach4 section of the forum. Assuming you are actually still running Mach3.

Thanks,
Jim
