9. Transceiver input power is reverse polarity protected Antennae Requirements When purchased as part of The Oceanscience Group Riverboat System the remote boat transceiver utilizes a rugged 2 4GHz 900MHz antenna while the base unit comes equipped with an omni directional antenna All antennae their connectors and cables have 50ohms of impedance Using other antennae connectors or cabling could result in unsatisfactory results Placement of your HydroLink SL base unit is likely to have a significant impact on its performance Generally the higher the placement of the antenna the better the communications link height is everything In practice you should also place the transceiver away from computers telephones answering machines and other similar equipment To improve the data link Oceanscience offers directional and omnidirectional antennas with cable lengths ranging from 3 to 200 feet and of varying gain When using an external antenna placement of that antenna is critical to a solid data link Other antennas in close proximity are a potential source of interference It is also possible that slight adjustments in antenna placement as little as 2 feet will solve noise problems In extreme cases such as when the transceiver is located close to pager or cellular telephone transmission towers Oceanscience can offer band pass filters a standard filter and a cavity filter to reduce the out of band noise RS232 Interface Because th
10. e transceivers serial data parameters are fixed instruments and any related application PC software must be set to match The serial data rate for the HydroLink SL is 115 200 When configuring the instrument and application software to match the transceiver the PC and instrument should be connected directly Do not attempt to change instrument settings using the transceivers Communication is not possible until the instrument and application software settings match those of the transceivers Some instruments transmit or receive control pulses using the computer RS232 com port Because the transceivers transfer binary data with a pre defined data byte length attempting to send control pulses using the transceivers is not recommended A specific example of this is the wake up or break command used by some ADCP manufacturers The standard wake up command is a 300 ms pulse sent from the computer comm port to the ADCP If this pulse is routed through the transceivers it will not be recognized by the ADCP The solution to this format conflict is to use the ADCP alternate wake up command of three ASCII equals signs Using this alternate control command maintains the binary data format and will be recognized by the ADCP through the transceivers All instrumentation connected to the transmit and receive data lines of the transceiver should be verified to use RS 232 format Troubleshooting This section lists some problems

12. rcular Micro Change connector The SL is designed to operate as a DTE Data Terminal Equipment When connecting to a DCE Data Communication Equipment a straight cable should be used When connecting to another DTE a crossover serial cable must be used The crossover cable must have TD and RD crossed pins 2 3 and 3 2 The Base Transceiver should be connected to the computer The Remote Transceiver should be connected to the instruments Transceivers are provided as a matched pair that communicates only with each other Each unit of the pair set is programmed with a unique serial number I D When using the cables provided by The Oceanscience Group note that the 8 pin circular connector is keyed and will not align in any way except in the correct alignment Once the keyway is properly aligned the backshell of the connector should be screwed to finger tightness This connector is IP68 rated when properly connected The antenna connector is type SMA and care should be given so as to not cross thread the connector Again finger tight is adequate when threading on the antenna cable Power Requirements The HydroLink SL series transceiver should be powered from a clean DC power source Input voltage range must be between 10V and 14V Power source should be capable of supplying a peak current of 1 0 Amp Power cable to the transceiver should be routed away from the antenna Close proximity between the two may result interference
13. the MaxRad antenna from the boat This avoids the possibility of over modulation Once you ve established communications in the lab you should reattach the MaxRad antenna and test at a greater separation 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 115 200 bps This matches the default baud rate of your HydroLink SL See section 1 Configuring the ADCP for details on how to do this The next step is to install the ADCP in the Riverboat see separate 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 If you are receiving data from the ADCP 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 your discharge measurements Overview Thank you for purchasing an Oceanscience Group product It is our intention to provide our customers with the latest technologies the highest quality manufacturing and the most efficient customer service and support This manual outlines the use of HydroLink SL series Wireless Data Transceivers with specific references
