I am attempting to hook up RS-232 on an Integrex 40...with a T32-3 control. I have made up the cable..set " I " parameters. before I even plug the cable in and try to send or recieve a program, I get either a 515 error cmt misconnection or a 544 tape reader misconnection error, and then the same thing when I plug the cable in. Anyone have any recommendations to fix this problem Thanks in advance
