  • Page 4: Product Overview

    HyQuest Solutions Pty Ltd Product Overview The HyQuest Solutions Wireless Data Collector WDC100 has been designed using surface mount technology to provide a very small, ultra low power wireless SDI-12 and 4-20mA transmitter / SDI-12 receiver network that can be used in harsh environments for extended periods.

  • Page 5: Installation

    915MHz band, then you may need to try different frequencies until you find one that doesn’t clash. You could have several WDC100 OutPost “Systems” operating in close proximity to each other, on different frequencies. Also note that the HyQuest Solutions’...
  • Page 6 HyQuest Solutions Pty Ltd 5. Make sure your SDI-12 Logger can log all the variables you require! All of the data returned from Transmitter #0 will be translated to appear as data from SDI-12 address #0. All the data returned from Transmitter #1 will be translated to appear as data from SDI-12 address #1.
  • Page 7 HyQuest Solutions Pty Ltd Think of the Outpost Transmitter as a data collector – grabbing data from different sensors with varying SDI-12 address, and putting the data in the Outpost Receiver so the Data Logger can retrieve it any time it likes.

  • Page 8: Hardware Connections (Transmitter)

    HyQuest Solutions Pty Ltd Hardware Connections (Transmitter) The WDC100 Transmitter can monitor 1 x 4-20mA signal + up to 9 x SDI-12 parameters (in a single transducer or scattered over 9 x transducers) + a digital input from say a TBRG rain gauge or a water flow meter + the battery voltage powering the transmitter itself.

  • Page 10: Hardware Connections (Receiver)

    HyQuest Solutions Pty Ltd Hardware Connections (Receiver) The WDC100 Receiver collects data from up to 8 x WDC100 Transmitters and it can also monitor 1 x 4-20mA signal + a digital input from say a TBRG rain gauge or a water flow meter + the battery voltage powering the receiver itself.

  • Page 24: Appendix C Buoy Breather Bag Setup

    HyQuest Solutions Pty Ltd Appendix C Buoy Breather Bag Setup We have changed the transducer venting in the Buoy for several reasons : ‐ Vented transducers always have a problem with moisture collecting in the vent tube. ‐ Venting the vent tube to atmosphere means that the electronics PCB is also vented to atmosphere, which in a marine environment will ultimately lead to corrosion forming.

    HyQuest Solutions Pty Ltd Appendix D Sending Custom SDI-12 Commands Once a system is installed and operating, it may be convenient to remotely access a sensor’s SDI-12 custom command set - to adjust a parameter, read an internal setting etc.
  • Page 28 Method 1 : Connect a PC to the Outpost Receiver via an “RS232 to SDI-12” adapter (available from HyQuest Solutions) and run the application supplied, called “Outpost Express”. (This application will encapsulate the SDI-12 command and monitor its progress through the...
  • Page 29 HyQuest Solutions Pty Ltd To operate the “Outpost Express” application, first select the comm port that is connected to the RS232 to SDI- 12 adapter. (If unsure of the COM number, select them one at a time until comms is achieved!)
  • Page 30 HyQuest Solutions Pty Ltd As the transmission sequence occurs, various messages will appear which indicate the request progress. When complete, the SDI-12 response from the command will be passed back through the network and appear as a green highlighted message – as shown.
  • Page 31 HyQuest Solutions Pty Ltd Method 2 : If the Data Logger or RTU connected to the Outpost System has an “SDI-12 Transparent” mode, the required custom command may be sent through the Data Logger or RTU. If the Data Logger or RTU is connected via a modem, then these commands may be sent through a 3G telemetry network –...
  • Page 32 HyQuest Solutions Pty Ltd The SDI-12 X-Command format is as follows : Request a Custom Command : As with any SDI-12 command, the first byte is the address of the transmitter, and in the case of the Outpost, this is a number 0 to 7. This SDI-12 command directs a custom command to a particular sensor on a particular Transmitter.
  • Page 33 HyQuest Solutions Pty Ltd *** NOTE *** ‐ Commands will occur faster if the poll time to a Transmitter is set to “0Min”. ‐ If the poll time is set to any time other than “0Min”, the remote Transmitter will only respond to the SDI-12 command request when it wakes up on the next 1 minute interval.
