Sorry about that, I did not count the pins before I posted, this FX1-30MR has a 15 pin inline connector which connects to a handheld programmer and a Serial Connector 25 pin but the connector is the wrong gender for my cable that I use for all the other Mitsubishi PLC that I work on. I tried to upload a picture but I could not get that accomplished. I will try that again when I get a smaller file size picture. Thanks for all the reply's. I am anxious to read more.
