Introduction
The WaveGuide system is a very accurate level gauge which is compact, robust and easy to install. It is suited to
measure water level, tide and waves, up to the most extreme conditions. The system consist of a radar unit and a
server unit.
The WaveGuide Radar unit is based on Enrafs tankgauging radar the 973 Smartradar. It uses radar to measure
the distance between the radar antenna and the water surface.
The radar is mounted above open water. A flat 20 cm patch antenna (the F08) is used. The radar can be mounted at
any suitable location with free space to the water.
The WaveGuide Server unit (WGS) takes care of all data handling ( collection, processing, distribution,
presentation and logging) also it facilitates commissioning and (remote) servicing of the system.
The radar is connected with the server via a RS485 serial link allowing a maximum cable length of 1200m.
All facilities are made easily available via the build in web server and the standard web browser at your own
computer. The web server facility is the most convenient way of communication but not the only one. It is also
possible to communicate via one of the serial ports.
In this manual first mounting and installation is described followed by the commissioning of the system via the
user interface. Secondly all facilities are described, successively data processing, data presentation, data
distribution and data logging.
In appendix1 detailed information is given about all available information. Appendix2 describes for the expert
user how to configure the system via the properties file. In case the web browser interface can not be used is for
the expert user the communication via the serial port described in appendix3 . The measuring principle is
described in appendix4. Finally the system specifications are given in appendix5.

Installation
The WaveGuide Sensor
The WaveGuide radar can be positioned at any suitable mounting location with free space to the water. It is
advised to choose a position such that the radar beam is free from large reflecting obstacles (beam width F08
antenna 5 deg half top angle). This does not only includes horizontal objects in the beam , such as ducts, but also
vertical structures as bridge pillars, quay walls, legs of an oil rig, etc. It is recommended to mount the WaveGuide
at a minimum distance of 0,1x the height of the pole or qua wall.
The sensor has four mounting holes (Ø 11mm) in the top flange and lid equally distributed at a circle of 240mm
To facilitate the mounting, a mounting plate and a rail
mounting are available.
Reference level for the measured distance to the water
surface is the bottom side of the sensor unit.

Cabling
On top of the sensor unit there is a connection box. The five pole Phoenix connector is wired as indicated in the
table below.
The cable gland is meant for cables with a diameter
between 9 and 13 mm.
Mains: Mains supply is 24-64VDC. Supply variations of +10% and – 20% are allowed. The power
rating is max 18W.
Communication : Standard the WaveGuide radar communicates with the WaveGuide Server via an RS-485
connection (A, B and signal ground). The cable must be twisted pairs and shielded (eg.
Novasub DLR3). The maximum length is 1200 m. The shielding must be connected to ground
to both sides of the cable. There can be a potential difference between the grounds at the radar
location and the server location. Therefore a capacitor (10 to 100 nF) should be applied on one
side of the cable between shield and ground.

The WaveGuide Server
The WaveGuide Server (WGS) is available in two versions an IP67 version and a rack mount version. The IP67
version is a 190 x190 mm polycarbonate box. Connectors, buttons and display are all on one side. Cables are fed
via a removable cover plate. The rack mount version has a 19'' front panel (2U height). It has the push buttons and
the display at the front and the connectors at the back side.
Most connections can be made via two 10 pole screw connectors.
The right connector is to connect the radar and the supply.
●Pins 1,2 and 3 are to be connected to the corresponding terminals 1,2 and 3 in the radar. The link is
RS485.
●To facilitate a “one cable” connection to the radar it is also possible to feed the radar from the WGS by
pins 4 (+) and 5 (-). The power via these pins is switched on and of by the main switch of the WGS.
●Via pin 7(+) and 8(-) of the right plug the WaveGuide Server is powered by 24VDC (18 – 36VDC)
●Pin 9 and 10 are connected with the housing of the WGS in order to connect a protective ground.

The left connector is to connect to the computer ports of the WGS as defined below. Pins 2,3 and 5 of these serial
ports are parallel available on the left connector block and on the subD connectors.
Pin 7 of the left plug is not connected to avoid damage in case by mistake the right connector with the power is
placed in the left plug.
COM1: This port is reserved for service. By means of a terminal the expert user can log in the system.
(RS232). See appendix 3.
COM2: This port is reserved for transmission of data selected by the user. (RS232)
COM3: This port is reserved for transmission of data selected by the user. (RS232)
LAN: The WGS can be connected to the network with a straight network cable to the switch of the
network or direct to a (laptop) computer via a cross cable.
Inside the WaveGuide Server there is a PC104 computer with a Linux operating system. It takes about 2 minutes
to start up and during that time the display indicates “STARTING WGS”. After start-up the this message
disappears and new information is presented.
The WaveGuide Server is designed to facilitate the use of the WaveGuide System. The easiest interface for the
user is the built in web server. By means of the web browser (Internet Explorer, Firefox etc.) all facilities are
available. At the LCD display information about the system and measured parameters are presented, controlled by
five push buttons. They are numbered from left (1) to right (5). The information is organized in groups.
Button 1 to scroll through items in the group.(active sensor, parameters, network info, time, data storage)
Button 2 to scroll through the items in the group.
Button 5 is used in the data storage group to safely remove the USB disk.
Button 3 and 4 are reserved for future use.

Commissioning the system
To set the WaveGuide system in operation the following steps has to be made:
•connect the WGS to a computer
•become an authorized user
•inspect the quality of the measurements.
•set sample rate, mounting height.
•set system date/ time.
•configure the distribution of data.
Connect the WGS to a computer.
Inside the WaveGuide Server there is a web server available. Ones the WaveGuide Server is connected via LAN to
a computer, communication with the web server is possible with any modern web browser with javascript enabled
(Explorer, Mozilla, Opera etc.).
If it is not possible to establish a network connection it is also possible to service the system via serial port 1. Only
an expert user should do this. In appendix 3 this is described.
The computer is connected with the WGS via a network cable, straight to a network switch or direct via a cross
cable. During startup the WGS starts broadcasting for a DHCP server in the network to obtain an IP address. If
there is no DHCP server responding the WGS will become a DHCP server itself with default ip address
192.168.111.71. A computer that will try to make a connection with the WGS will obtain an IP address from the
WGS in the range 192.168.111.80 to 100. The actual IP number of the WGS is also presented at its LCD display
(scroll via button 2 until the network info is displayed and then by button1 scroll through name and address.
The default IP address can be modified via the web interface.
Type the ip address or name indicated on the LCD display (e.g. http://192.168.111.71 or http://wgs6) in the
address line of the browser. Figure 10 gives the opening screen of the WaveGuide Server.
At the left side bar there are the 10 main topics of the interface:
Measurements Recent raw measured data can be presented in a graph.
Parameters The calculated parameters can be presented graphically.
Spectra The energy density spectrum of the waves can be requested.
Data logger Data logging is available as an option.
