I have tried com ports 1 through 8, no go. I have to use a serial PLM to work with the ISY. The PLM that comes with the EZIO is also serial.
The readout above indicates the utility is talking to the comm port, it just can’t get anything from the 2413S PLM.
I am using the device manager settings to control the comm port. What serial port settings does the PLM expect? 9600 8N1?? What flow control? Should the Utility be in XP or Vista compatibility mode? Would be great to have a Wiki or some guidelines.
