Can I connect from my laptop 9 pin serial port directly to the RS 232 port of a 1785-KE card on a PLC5 rack and what are the connections ? Many thanks Fred Edited by Fred

For reasons that are lost to the mists of time, the RS-232 port on a 1785-KE is an oddball 15-pin connector instead of the more common DB9 or DB25 styles. But yes, you can connect directly to your computer's RS-232 port. The pinout is on page 4-3 of the User Manual: http://www.ab.com/manuals/cn/1785652.pdf RSLinx DF1 Full Duplex is the driver you will use, with the Device Type set up for "KF2/KE".
