    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,…[Read more]

  • Hi Sara,

    Thanks for the reply and pointers! I bought an adapter, but I’m unsure if I’m hooking it up correctly. Would you mind looking at the attached pictures for reference? I’m unsure of how the converter takes in serial data and sends it to the Mayfly…

  • Hi all,

    I’m am attempting to hook up an acoustic Doppler current profiler to the mayfly logger to output binary data via RS485 serial (RX0/TXO) as half duplex, 8 bit no parity no stop. Any suggestions on how to go about this? The data output is in this format here: rowetech binary: h…[Read more]
