Wire the junction box using the wiring diagram below (see Figure 7) To prepare
the cables, follow “Preparing the Wires”.
Connector on Display End
If the WeatherStation cable has a connector on the display end, and it can be
plugged into the port on the NMEA 0183 display; do so now. Coil any excess
cable and secure it with cable ties to prevent damage. Fasten the cable in place.
No Connector on Display End: Wiring
CAUTION: The WeatherStation Instrument has either an RS422 or RS232
interface. Follow the wiring diagram that matches the WeatherStation Instrument.
If it is wired for the wrong interface, it will not transmit and receive data properly.
CAUTION: The display power may be wired directly to the WeatherStation cable,
or it may be wired separately.
Heater models MUST be wired separately.
CAUTION: Heater models—It is recommended to use the same 24VDC power
supply for both the WeatherStation Instrument and the heater. If using separate
power sources, ensure that the supply grounds are common.
Preparing the Wires
NOTE: If the display does not have NMEA 0183 output connections, the yellow
and orange wires are not needed. Apply heat-shrink tubing to each unused wire.
Alternatively, the yellow and orange wires can be connected to an external sensor.
1. Allowing an extra 25 cm (10") for wiring ease, cut the cable to length.
2. Strip 60mm (2-1/2") of the outer jacket and foil shielding from the cut end of the
cable (see Figure 8 or 9).
3. Strip 10 mm (3/8") of conductor insulation from the end of each colored wire.
4. Protect the cable’s foil shielding from causing a short by using heat-shrink tubing
around the jacket where the wires emerge from the cable. The tubing must
overlap the wires a minimum of 6mm (1/4"). Shrink the tubing using a heat gun.
5. Being sure the power supply is OFF, connect the wires to the display.
6. Fasten the cable in place.
7. The installation is complete. To begin receiving data, refer to the owner’s
manual that came with the display.
