2 kW scanner comes with a 15 m (49 ft) cable (B) attached.
4 kW scanner comes with a 15 m (49 ft) cable (B) which will need to be
connected
Optional 20 m (65.5 ft) scanner cable . Will require disassembly of scanner to
connect. Cable has a radar processor connector on one end, and three small
terminated flat connectors on the other.
CAUTION: This cable should only be installed by an experienced radar service
technician!
Radar processor. No cables supplied. Connects to displays via RS485 protocol,
using optional radar connection cable kit. The 2 kW system is 12 V DC ONLY
25 W max. The 4 kW is 12-24 V DC
AT40 SimNet to NMEA0183 converter. Supplied with NX40.
AT45 SimNet to NMEA0183 converter. Supplied with NX45.
Converts SimNet data to NMEA 0183. Data from the SimNet such as position
and heading is passed into the NX unit to allow for accurate chart overlay.
Note: If there is no heading sensor on SimNet, chart overlay can be achieved
when the boat is underway and moving at a speed greater than 1 knot.
The AT40/AT45 has two SimNet ports and a 2 m (6 ft) cable terminating with
8 pin female connector. This plugs into socket labeled GPS on the NX40 NX45
display.
HD radar serial comms cable 3 m (9.8 ft):
This cable connects the NX display unit to the radar processor. The cable has
a 8 pin female connector on one end which attaches to the port labeled
RADAR on the NX unit. The other end has a 12 pin female connector which
connects to the port labeled NMEA / COMMS on the radar processor
Heading sensor Y cable, optional method:
Single end has a 12 pin female which connects to HD radar processor port
labeled NMEA /COMMS.
Connector 1 has a 12 pin male. Cable E connects to this then to the NX
display.
Connector 2 has a 8 pin male and connects to cable G which terminates in
bare wires.
NMEA Receive Cable, optional method:
250 mm has an 8 pin female that connect to the cable F. The other end has
bare wires. Black is NMEA IN negative. White is NMEA IN positive. This
connects to the NMEA 0183 heading sensor (NMEA out). A junction box may
be required.
Navico GS10 SimNet GPS antenna. Can ship with NX unit depending on part
number of display (see below).
The antenna has a 5 m (16.5 ft) SimNet cable attached.
Installation note. The SimNet backbone needs to be planned to go within a 5
m cable run of the antenna.
RC42 Heading sensor (or use SimNet heading output from an autopilot). A
heading sensor is optional when using an NX. If there is no heading sensor,
course over ground from the GPS is used.
Simrad NX40 or NX 45 or Northstar M84 or M121.
