I am having an RS232 Communication Alarm: BG806 Device type mismatch. Bit of a brain teaser that I don't think should be very hard, but I am missing something. I restored factory parameters on a Fanuc 15M-A from a backup file. When I send a program to or from the machine at the end of the data transfer I get this alarm. If I go and look at the program for example from the PC to the machine. It loaded correctly and runs fine. I played with all the communications parameters for a few hours trying different things with no luck.
The machine has two RS232 input devices. Both the RS232 and a tape reader. The RS232 port is plugged into I believe CD4A port and Tape is CD4B.
