Hi,

I was wondering if anyone has found a way of making the VFD TECO 7300CV communicate with mach4
Its connected to my PC over a DB-9 cable, I believe RS-232.

I know the spindle works properly Everything works when I am running my old controller software on the PC, but not yet working in Mach4.

I attached the documents I could find on my VFD.  There is all this talk about 232 485 and Modbus and it has me a little confused.

The application is the MicroKinetics Express XL Mill, in case any one is curious.
