    In the 4-20 mA option, both SDI-12 and the 4-20 MA connections must be made. 4.1 SDI-12 MILITARY BAYONET CONNECTOR When using the Radar Stage Sensor with an FTS Axiom Datalogger, the sensor is supplied with the SDI-12 cable with military bayonet connector installed.
  • Page 13: Sdi-12 Connection

    4.2 SDI-12 CONNECTION Use 3 wire, shielded cable, preferably with red, black, white colour-coded conductors. Use cable with a round cross section and an outer diameter of 0.17” to 0.45” to ensure the IP protection rating seal of the cable gland. Conductor gauge must be in the AWG 20 - 24 range. SDI-12 connection steps are as follows: 1.

    4.3 4-20 MA OUTPUT OPTION CONNECTIONS Normally, the radar will be shipped with all internal electrical connections in place. However, should the supplied cables need to be replaced, the cover from the electronics enclosure on the side of the instrument must be removed to make the connections. Connect the SDI-12 cable as directed in the previous section.

    MOUNTING 5.1 GENERAL The radar sensor can be mounted directly onto a vertical, horizontal, or angled surface using the mounting bracket. Additionally, it can be mounted using an optional flange attachment which accommodates mounting in an enclosure for added protection and security. 5.1.1 PROTECTION AGAINST MOISTURE Protect your instrument against moisture ingress through the following measures: Only use the supplied cable and gland...
  • Page 17 NOTE: When the housing is rotated, the direction of polarization changes and hence the influence of the false echo on the measured value. Keep this in mind when mounting or making changes later. Polarization Figure 5-1: Polarization Markings Ideally, the polarization markings should be turned towards the nearest vertical surfaces to minimize interference with the transmitting waves.
  • Page 18: Installation Obstructions

    5.2.3 INSTALLATION OBSTRUCTIONS The mounting location of the radar sensor should provide a clear view to the measured surface with no equipment or fixtures crossing the signal path. Installations with obstructions such as ladders, struts, etc., can cause false echoes and impair the useful echo. If obstructions cannot be fully avoided, false echo storage should be carried out during setup (see section 9.6).

    6.1 SETTING UP WITH THE FTS AXIOM DATALOGGERS Attach the Radar Stage Sensor to one of the Datalogger’s SDI ports the using the military connector. There are two extensions which can be used depending on which SDI-12 “M” command is used.
  • Page 21: Setting Up Using The Radar Extension

    6.1.1 SETTING UP USING THE RADAR EXTENSION IMPORTANT! Once the Radar is setup, it MUST be mapped. Instructions on mapping the sensor follow the setup instructions. After selecting the Radar Extension, the Radar Setup screen will be displayed: SENSOR TAB: Sensor Name: The default sensor name is Radar.
  • Page 22 Read: The read button appears on all tabs and will trigger a sensor reading and return the measured values for the fields (averaged Stage and quality metric) in addition to the measurement time. Figure 6-4: Read Button Results SCHEDULE TAB This tab is used to setup how often samples are taken and averaged, and how long the averaging duration lasts.
  • Page 23 Mode: There are two power modes: High Power: In high power mode, one sample is taken every second, continuously. These are stored in the buffer. When the scheduled time arrives (based on the input interval and offset times), the most recent samples taken will be used for the average in accordance with the Averaging Duration (ie: an averaging duration of 20 seconds will use the last 20 samples in the buffer).

  • Page 29: Using Sdi-12 Commands With Axiom Dataloggers

    SDI-12 COMMANDS The Radar Range Sensor is capable of reading and writing with the standard set of SDI-12 commands. 8.1 USING SDI-12 COMMANDS WITH AXIOM DATALOGGERS To use SDI-12 Commands, the Datalogger must be in Transparent Mode. From the Home screen select the SDI 12 >Transparent Mode.

    8.2 SDI-12 NOTATION SDI-12 commands are strings of characters sent to the SDI-12 device. The format of the strings is important, and to specify the format of SDI-12 commands different typefaces are used. All commands to and the replies from the device are represented in a mono-spaced font. Different parts of a command are represented with variants on this text format Item Explanation...

  • Page 33: Comparison Of The M And M1 Commands

    8.4.1 COMPARISON OF THE M AND M1 COMMANDS The M Command averages all the measurements taken over the Averaging Duration. This produces less erratic values than the M1 Command, especially in turbulent water, as troughs and crests are averaged to produce a more accurate assessment of actual stage. The M1 Command produces more erratic data as the logged value is from a single measurement, each of which can be influenced by troughs, crests, and other interference resulting in a wide variance between a series of measurements.
  • Page 34: Commands

    8.5 X COMMANDS In addition to the standard set of commands the FTS Radar Range Sensor has an extension of custom SDI commands called X commands that access specific features of the sensor. The format of X commands follows the requirement for standard SDI commands in that the first character of every command must be a sensor address which is then followed by the X command and terminated by an exclamation mark.

    DISPLAY AND ADJUSTMENT MODULE 9.1 GENERAL The display and adjustment module (module) is used to set up the sensor and assign specific parameters to adapt the instrument for its environment and application conditions. The radar will be configured using the display and adjustment module prior to shipment. However, the module will need to be used on-site should a false signal suppression need to be carried out due to obstructions (see section 9.5).
