    While the other end is a pin wrench that can be used for tightening the radar housing to the antenna. Upon request, Radac can supply an optional frame (Part no. WG-MH-EX) that allows for mounting the WaveGuide radar and mounting plate at angles 0, 5, 10, 15 and 20 [deg] away from vertical (see Fig.2.6).

    Housing To access the WaveGuide radar case: • Open cover A as shown in Fig.2.8. • Open and remove cover B as shown in Fig.2.9. • Use an 8 [mm] Allen key to loosen the 16 bolts of the housing. Make sure the 4 bolts on the side of the hinge are entirely screwed into the cover and do not protrude Figure 2.8: Cover A.

    The poles numbered 06 and 07 labeled RFL:LED+ and RFL:LED- are pre-connected to a status indicating LED. Upon powering the system the status LED will turn on and continue to shine while the system is starting up. When the startup process is completed and the system is running in normal mode the LED will blink every 4 [sec] ( 2 seconds on and 2 seconds off).

  • Page 24: Step 1. Connect The Waveguide System To A Computer

    Step 1. Connect the WaveGuide system to a computer Once the WaveGuide system is connected to a Local-Area-Network, communication can be done via the available web interface (Fig. 3.1). For this purpose any web browser with JavaScript enabled can be used. Figure 3.1: The web interface of the WaveGuide system.

    In that case, the authorization data will be submitted automatically by the browser without a pop-up dialog. The default login password is “radac”. After successful authorization, the user can view and change settings. After submitting any new settings a reboot dialog will appear.

  • Page 26: Step 3.1: Set System Date And Time

    If the WaveGuide is not connected to the Internet but instead connected to a local network that includes a time server, then the WaveGuide system can be adjusted to synchronize time and date with the local time server. For more information regarding such an adjustment please contact Radac.

    Step 3.2: Adjust network settings Figure 3.3: Adjusting the network settings. The default IP address can be modified via the web interface (Fig. 3.3). It is advised to use the default settings, to automatically obtain the network settings from a DHCP server, and to ensure that the system will receive the same IP address from the DHCP server at all times.

  • Page 28: Step 3.3: Sensor Configuration

    Step 3.3: Sensor configuration The WaveGuide Onboard is designed with a high level of flexibility in mind, to apply to every possible mounting situation. The sensor menu as shown in Fig. 3.4, allows the configuration of the parameters that are specific to the sensor mounting position. Figure 3.4: Setting sensor parameters (changes only take effect after the system is rebooted).
  • Page 29 Min. range The range minimum is the minimum distance at which the sensor will detect the water level. This parameter is used to avoid spurious measurements and should be set depending on the installation location. If there are any nearby surfaces that can reflect the radar signal the range minimum should be set to a value higher than the distance to those reflecting surfaces.

  • Page 30: Step 4: Perform System Check

    Step 4. Perform system check This section explains how to inspect the quality of measurements after configuring and rebooting the WaveGuide system (the start-up process can take up to 5 minutes). Step 4.1: Check system information The system information table can be reached through the status menu item on the top-right of the web interface.

  • Page 31: Step 4.2: Check Reflection Diagrams

    Step 4.2: Check reflection diagrams The reflection diagram of the radar can be accessed via the sensor configuration page by clicking on the corresponding "reflection" button (Fig. 3.7). A reflection diagram is a graphic representation of a single measurement, where the signal strength [dB] is plotted against the measurement distance [m].

    Step 4.3: Check measurements The ’Dashboard’ page, gives the possibility to view plots of different measured and calcu- lated parameters. Please note that, as a result of calculations preformed some parameters are shown with a constant delay such as heaveIMU and heaveWOB (100 and 120 [sec] of delay).

    Default message format The Default format starts a new line for each parameter in the subscription. The time used in the Radac format is Unix Epoch time in milliseconds (UTC time in milliseconds since 00:00:00 on the 1 of January 1970). Each line in the Default format ends with a Line-Feed character (char10).
  • Page 34 Format01 message format The Format01 message, formerly called the SESAM format, used by the Dutch Ministry of Infrastructure and the Environment (Rijkswaterstaat), is only defined for the heave and the 10 second mean (H parameter). It consists of 8 character lines (Line-Feed character + status character + sign character + 4 character value in cm + Carriage-Return character).
