Preparing the Cables
The Airmar Combination Cable is able to transmit data in both
NMEA 2000 and NMEA 0183 formats. The cable can be cut into
two parts (see Figure 1). The section with the sensor connector
becomes the sensor cable. The remaining section with the 7-pin,
NMEA 0183 connector becomes the NMEA 0183 cable.
Sensor Cable
1. Route the Combination Cable from the instrument/receiver/
sensor to the Splitter.
2. Allowing an extra 25cm (10") for wiring ease, cut the cable to
length. (Set the remaining section of the cable aside. It will be
used to connect the NMEA 0183 device to the Splitter.) Do not
connect the sensor cable or fasten it in place at this time
NMEA 0183 Cable
The remaining section of the Combination Cable will become the
NMEA 0183 cable.
1. Route this cable from the Airmar Data Converter, Airmar
Combiner, or NMEA 0183 instrument to the Splitter.
2. Allowing an extra 25cm (10") for wiring ease, cut the cable to
length. Do not connect the cable or fasten it in place at this time.
NMEA 2000 (Network) Cable (see Figure 2)
1. Route the NMEA 2000 cable from the network node to the Splitter.
2. Allowing an extra 25 cm (10") for wiring ease, cut the cable to
length. Do not connect the cable or fasten it in place at this time.
Connecting
1. Remove the cover of the Splitter. Set it aside along with the two
screws, the packet of silicone lubricant, and the bag of 6 x 1/2"
screws and butt connectors.
2. Following the label on the Splitter cover, push approximately
200mm (8") of each cable through the appropriate compression
nut (see Figure 3).
3. Strip 60mm (2-1/2") of the outer jacket and foil shielding from
the cut end of each cable (see Figure 4).
4. NMEA 0183 Cable Only (see Figure 5)
• Cut off the white and blue wires flush with the cable jacket.
• The black wire and the red wire will NOT be connected.
Cover the end of each wire with heat-shrink tubing to prevent
the possibility of a short circuit inside the Splitter. Use a heat
gun to shrink the tubing.
