I have used RS232 Communications for CNC machinery for many years. However have not been able to find any good information on the different cable setups used as well as an understanding of DC1-DC4 codes and such. I am usually able to get things to work after trial and error, but would like some documentation on the subject. I am also looking for information on the different handshaking protocals and what is required for the cable pinouts. I have purchased cables in the past which sometimes work for a specific machine and not others so many times I have had multiple cables. Some will wait for the machine to be ready and some will not. The best combination I have found is to buy a null modem, DB9pin to DB25 adapter and a DB9pin 10ft cable. If I purchase as one unit it seems to funciton differently. I know I asked a lot of questions but they are all somewhat related.
Thanks
