To take under consideration when connecting to an NMEA2000 network:
•
CTRX Graphene and CTRX G shall be connected to the NMEA2000
network as so called ”drop” units.
•
The ”Drop” cable from the AIS unit to the NMEA2000 ”backbone” must
not exceed 6m.
•
There is no end resistor in the AIS units.
•
The NMEA2000 network must be power supplied (12VDC) separately.
•
The NMEA2000 ”backbone” MUST have one end resistor at each end of
the NMEA2000 ”backbone”.
•
Power supply of the AIS unit is made according to previous page:
”– Connection of power supply and external units via NMEA0183 – ”.
•
NMEA2000 cables, T-connectors and/or end resistors are not enclosed
with the AIS.
•
The LEN value of the CTRX Graphene and CTRX G is 1**, respectively.
**To learn more about LEN values and NMEA2000 in general,
please contact you local certified NMEA2000 dealer.
