    Thanks for the help!

    I ran into another problem as I think something happened and I blew a chip in the ADCP… I’m trying to determine if voltages were different. The RS232 and 485 chips in the ADCPs are 3.3V and I thought I had everything hooked up correctly to the right voltages, but I’m wondering if the Tx and Rx on the board are 5V output, or the TTL converter somehow pushes out 5V (the documentation on the converter is confusing).

    Sorry for the confusion on the red, black and white wires, they were just leaders attached to the end of the cable I had – red=blue and black=orange and white=green.
