I'm trying to set up communications with my Fadal mill. I know that some machines require a jumper box so you can match up the wires from the RS-232 port to the port on the back of the machine. Do Fadals require this? Is there any thing else I should know about setting up Comm. with a Fadal? I've tried typing in TA,1,2 in the command mode to load a program and I can't get it to do anything so I'm not sure if I have it set up wrong or what. Anybody got any ideas? Thanks a million!
