Direct DRS Connection

IMPORTANT: Follow this chapter when the DRS radar is directly connected to the PC without MFD.

Power Supply Unit Connection (optional on some models)

Some newer DRS (such as the DRS4D-NXT) do not need any Power Supply Unit and can be connected directly to the main 12v or 24v battery (refer to the Furuno DRS installation guide for more information).

If the DRS model you use requires the PSU012 or PSU013 (Power Supply Unit) to power the antenna (48v), make sure to insert the “J7” jumper inside the PSU (under its cover). If the jumper is not inserted, the PSU will not power ON (the LED will remain OFF) even when 12 or 24v is provided

Note: If the PSU017 is used (for DRS dome antenna), there is no need to open the cover or insert any jumper.

Network Connection

To connect the DRS Ethernet port to the computer, we highly recommend installing a HUB/Switch in order to be able to add additional Ethernet sensors easily (FA30, DFF1, etc…) and to be able to monitor and troubleshoot network traffic (by looking at the activity LED of the HUB):

Connect GPS, Heading and optional additional instruments to the computer using one or multiple COM ports (through a USB to Serial adapter if needed) or through NMEA2000 via the Actisence NGT1 Gateway.

Important information regarding heading: If you want to overlay radar on the chart, acquire ARPA targets or use the North-Up Orientation of the Radar WorkSpace, you have to provide Heading to TimeZero. For reliable ARPA, the heading refresh rate must be 10Hz or more (the heading sentences must be received 10 times per second or more). If TimeZero only receives heading once per second, ARPA reliability is not guaranteed.

Note: If you connect the Heading Sensor using NMEA2000 the refresh rate is always 10Hz.

Set the IP of the Computer

The computer needs to have an IP address that “matches” the Furuno Network (172.31.x.x/255.255.0.0) in order to exchange information with the DRS. We highly recommended using 172.31.3.150 as a fixed IP address for the computer with a subnet mask of 255.255.0.0.

Open the "Network Connections" control panel of your computer to adjust the IP address. Under Windows 8.1 and Windows 10 you can press the combination shortcut “Windows Key” + X and select directly the "Network Connections". Under Windows 7, click on the Windows “Start” menu and search for “Network”. Under the “Control Panel” category, click on “Network and Sharing Center”. Once the Network and Sharing Center window is opened, click on "Change Adapter Settings".

Double click on the Network Adapter connected to the radar (usually “Local Area Connection”).

Note: If you have multiple Area Connections (multiple Ethernet Cards) and if you don’t know which one is connected to the radar, you can temporary disconnect the Ethernet Cable from the computer and look at which icon will display a red cross. This will indicate the LAN that has been disconnected from the computer, and thus the one that needs to be configured.

Select "Properties" on the "Local Area Connection Status" window. Double click on “Internet Protocol Version 4 (TCP/IPv4)”. Use the fixed IP address 172.31.3.150 with a subnet mask of 255.255.0.0:

Once the computer's IP address has been assigned, launch TimeZero in Navigation Mode. Open the "Options" by clicking on the "TimeZero" logo (located at the top left corner) and select "NavNet". Make sure that the Radar is detected. Do not proceed to the next step until all Furuno Ethernet sensors are properly listed.

Note: Make sure the DRS is turned ON before starting TimeZero. TimeZero will not display the Radar features if the DRS is turned OFF or not present on the network.

Configuration

Open the Radar Options in TimeZero. Under "Radar Initial Setup", select the DRS Hostname and adjust the DRS initial settings just like you would from a NavNet3D or TZtouch MFD.

Note: There is no feedback when pushing the “Radar Optimization” button. This is normal!
