We have a legacy design using the RCM2020. We program it using RFU version 2.25 to match the DC version 7.25 that it was programmed in. Recently the computer that we used for the programmer died, and I am trying to get the RFU working on a new Dell desktop computer running XP using the Rabbit RFU to Serial cable.
The serial port is accessed based on the LEDs on the cable, but it does not see the RAbbit module. I have tried it with the "Use USB To Serial Converter" selected and deselected, I have tried with the baud rate reduced, but still no Rabbit detection.
In the control panel, system, hardware section there are several other settings and before I try to change them I was wondering if they made any difference- currently they are set to 8 bits, 1 stop, no parity, no Flow Control. Plus of course the baud rate matches the rate I am trying from RFU. Does any of this make a difference?
The programming still works on another computer running Windows 98 with a serial port, so there is no problem with the Rabbit cable or the module itself.
