Connecting to a Data Converter, Combiner, or Splitter
Follow the installation instructions that are supplied with the unit.
Connecting to an NMEA 0183 Display
Route the WeatherStation cable to the display. Do not fasten the cable in place at
this time.
Connector on Display End
If your WeatherStation cable has a connector on the display end, and it can be
plugged into the port on your 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
If your WeatherStation cable does not have a connector on the display end, it
must be hard wired. Referring to the owner’s manual that came with your display,
connect the colored wires as shown in Figure 6, or Figure 7 if your WeatherStation
Instrument has a heater.
CAUTION: Your WeatherStation Instrument has either an RS422 or RS232
interface. You must follow the wiring diagram in Figure 6 or 7 that matches your
WeatherStation Instrument. If it is wired for the wrong interface, it will not transmit
and receive data properly.
CAUTION: Heater—It is recommended to use the same 24V power supply for
both the WeatherStation Instrument and the heater. If using separate power
sources, ensure the supply grounds are common.
NOTE: If your 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.)
NOTE: The display power may be wired directly to the WeatherStation cable, or it
may be wired separately. Models with a heater MUST be wired separately.
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 6 or 7).
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. Your installation is complete. To begin receiving data, refer to the owner’s
manual that came with your display.
