Hi, I have a foreign product that has very little information along with it. This program runs on a standard windows computer and connects to a specialized industrial type controller. The program opens and runs fine on the computer, however to connect it to the 9 pin female terminal on the controller these are the only instructions given:

3----------RXD-
4----------T/R+
7----------RXD+
8----------TR-

I'm believe that the numbers ref pin numbers on the male terminal I should connect to the controller, but I don't know what the original configuration of the 9 pin on a standard computer are to know what to do on the computer side?

Sorry, for my confusion.....I know just enough o get me in trouble, but not enough to know what to do here. Any help would be greatly appreciated.
