FAR 2XX7 Connection

The "Furuno Radar Module" needs to be unlocked prior configuring a FAR2XX7 series Radar in TimeZero.

Configure the Radar

Check and Assign Radar Hostname(s)

When multiple radars are networked or inter-switched together, a unique "Radar Number" (and IP address) must be assigned to each radar processor. Note that for TimeZero to correctly detect the radar, at least one Radar Processor must be assigned to 172.31.3.6.

IMPORTANT: The FAR2xx7 IP address must be set up to 172.31.3.6. TimeZero will not be able to connect to the radar if the FAR2xx7 is set to another type of IP address. If the FAR is set with an IP address of 192.168.31.x (for ECDIS), make sure to revert DIP#4 to the OFF position on S1, then perform a factory reset. This will switch the FAR back to the Class B 172.31.x.x IP address:

To assign the radar number, hold “HL OFF” and press the “MENU” key 5 times on the FAR 2XX7. The “Initialize” menu will appear. Select “Installation” (4), then Radar NO (4). Once the radar number is changed, the radar must be restarted to store the new setting. If applicable, follow the same procedure for each radar on the network, and then confirm that each radar number is unique. You cannot have two radars on the same network with the same name or number.

Note: Whenever a network change is made, it is recommended that all radars are powered down and restarted.

To confirm the network settings and communications between multiple radars, power up all of the radars in the network, then right click on the Radar Antenna box (top left corner). The antenna information for all of the available radars in a network will appear on the right in the menu panel. Be sure that all the radars on the network are listed in this panel. If not, check the cables and the network settings.

IMO Mode

When TimeZero is interconnected to the FAR2xx7 via the network, the radar should be set to IMO Mode B, C or W. To set the IMO type, hold “HL OFF” and press the “MENU” key 5 times on the FAR 2XX7. The “Initialize” menu will appear. Select “Installation” (4), then "Type" (7). Set to "B", "C" or "W" ("W" is recommended).

SIO LAN Output

The FAR2xx7 SIO LAN Output has to be turned OFF (which is the default setting on the FAR). To make sure this setting is OFF, right click on the “Own Ship Position” box on the FAR and select OFF for the “SIO Data LAN Output” (3).

Configure the computer

TimeZero connects to a Furuno FAR 2xx7 radar through an Ethernet connection (100Base-T). The computer needs to have an IP address that “matches” the Furuno Network (172.31.x.x / 255.255.0.0). We recommended using 172.31.3.150 as a fix 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 10/11 you can press the combination shortcut Windows Key + R to open the Run dialog box. Type "ncpa.cpl" and click on "OK":

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" from 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 IP address of the computer has been assigned, launch TimeZero in Navigation Mode.

Configure Instruments

Instruments (GPS, Heading, AIS, ...) need to be connected directly to the computer via NMEA0183 or NMEA2000. When connecting instruments to TimeZero, it is very important to make sure that the same GPS and Heading sources connected to the FAR radar are also used and connected to TimeZero. Connecting a different GPS and/or Heading source will result in radar overlay issue.

Note that it is possible to connect NavNet sensors (such as a DFF1-UHD sounder) to the same network so that TimeZero can display Radar and Sounder Echo:

Note: The FAR "SIO LAN Output" can interfere with other NavNet sensors (such as Ethernet Sounders) that may be present on the network, and thus, it should be turned OFF.

ARPA Configuration

TimeZero can operate in two modes for ARPA processing. It can either use the ARPA data processed by the Radar (default), or use its own local ARPA processing. This setting is adjusted from the Radar Options using the "ARPA Processing" option. If you want TimeZero and the FAR to share the same ARPA data, make sure to leave this option to "Radar Antenna" and configure the FAR radar and TimeZero with the instructions below.

2XX7 Configuration:
The ARPA target output must be setup through the LAN from one FAR2xx7. Hold “HL OFF” and press the “MENU” key 5 times. The “Initialize” menu appears. First, select “TT Preset” (6).  Select “True” for “TTM Output” (2). Select “Back” to return to the “Initialize” menu and select “Other” (8). Set “INS” (5) to “LAN”.

TimeZero Configuration:
In order for the ARPA target to be received over the network, you need to configure it manually in the software:

  • Open the Connection Wizard

  • Select "Manual Port Configuration" and click on "Next"

  • Select "Add/Configure UDP Connection" and click on "Next"

  • Select the IP address that begins with 172.31.x.x from the "Network Adapter" drop down menu and type "10028" for the "UDP Port". Click on "Next"

  • When TimeZero is done analyzing the port, select “UDP 10028” in the list on the left and make sure that “ARPA” is checked in the list on the right. Click "Next" then "Finish".

Note: You can only use the ARPA data from one FAR radar on the network.
