• Locate the data converter well away from areas subject to water splash and rain.
• Keep the data converter out of direct sunlight because of heat that can build up inside the
cabinet.
Mounting
Fix the data converter to the mounting location with two self tapping screws (3x20), referring
to the outline drawing in this manual.
Wiring
Connection to Furuno CAN bus device
Connect the Furuno CAN bus cable to the Furuno CAN bus device. See “Furuno CAN bus
Network Design” (TIE-00170-x) for details about CAN bus network.
Connection to NMEA0183 device
Connect the NMEA0183 signal cores to NMEA0183 device, referring to the interconnection
diagram as below.
Note1: NMEA0183 cable terminal is not waterproof. Therefore, install the equipment away
from areas subject to water splash and rain.
Note2: Wind vinyl tape around unused cores and fix the cores so that they do not touch
other signal cores or ground.
PORT1 (ORG), PORT2 (PPL), GND (BLK)

Conversion Mode
PORT1 (ORG), PORT2 (PPL), GND (BLK) signal cores of the NMEA0183 cables are
short-circuited (default). By cutting the specified signal core, the conversion mode can be
changed. Select the conversion mode according to the baud rate of the connected device.
For connection to an AIS device, select the AIS mode.
Note1: Check the applicable checkbox on the nameplate according to the conversion
mode selec
Note2: Wind vinyl tape around unused cores and fix the cores so that they do not touch

*: To change the conversion mode to “Normal”, cut PORT1 and PORT2.
Turning Power On
No operation is required for the user to turn the power on. The power is supplied by Furuno
CAN bus line. The Power LED (yellow) flashes when the data converter is powered.

Input/Output Comparing
Furuno CAN bus → NMEA0183
Some Furuno CAN bus PGN output a number of NMEA0183 sentences.
*: When the volume of sent data exceeds the communication band, the TX interval
becomes longer.
NMEA0183 → Furuno CAN bus
Some NMEA0183 sentences output a number of Furuno CAN bus PGN. The latest inputted
sentence is given priority.
NA means “
nonperiodic”.
ID means “Message ID”.
