I have a Hwacheon vertical lathe center with two spindles. The control is a Fanuc 18T, I have set up Muti DNC it is working with the OT controls on my other lathes but I keep getting the 086 DR Signal off alarm on the 18T. I am using three wire connections from a DB25 at the machine to a db9 RS232 switch. Pin 2-2, 3-3, and 7-5. 4&5 as well as 6, 8, &20 jumped at the machine side. We have a lap top with a wire that was made by someone else several years ago, and when it is hooked up we do not get the 086 alarm. I am wondering if I need to go to a different wiring schema on this machine. Any help will be appreciated. Thanks.
