OAT Using an RD Instruments WorkHorse series ADCP If this is the first time you have used your Oceanscience Riverboat system we highly recommend you familiarize yourself with the setup procedures prior to field deployment Testing in the office can save valuable field time While testing the transceivers in close proximity it is advisable to unscrew the MaxRad antenna from the boat This avoids the possibility of over modulation The most important phase of setup is configuring your ADCP so that it will communicate through the modems This is done by setting the baud rate of the ADCP to 19 200 bps This matches the baud rate of channel 1 of your HydroLink ML2 See section 1 Configuring the ADCP for details on how to do this The next step is to install the ADCP and GPS on the Riverboat see Riverboat Assembly Instructions Install the Remote transceiver in the Riverboat see section 3 Remote transceiver setup Establish communications between your transceivers by completing section 4 Base Transceiver Setup and System Power up Confirm ADCP data transmission through the transceivers section 5 WinRiver Setup You can confirm GPS data transmission in the same manner but your GPS antenna must have an unobstructed view of the sky If you are receiving data from both sensors you can simply turn off the Riverboat toggle and disconnect power to your Base transceiver Once in the field you can apply power and should be ready to begin
