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.
Inputs port 2
THC on
THC up
THC down
Outputs port 2
I do not know what's needed for outputs.
