Connecting The Cable - Simrad HS70 User Manual

Connecting the cable

1.
Align the cable connector keyway or the NMEA 2000 adapter with the HS70 connector key
2.
Rotate the cable ring clockwise until it locks. The locking action is firm, but you will feel a positive "click"
when it has locked
3.

NMEA 2000 Port
Powering the HS70 when used in a NMEA 2000 installation
To power the unit via NMEA 2000 connection, follow the standard procedure for powering of
a NMEA 2000 network.
Connecting the HS70 to External Devices
For connecting NMEA 2000 devices, plug the serial-to-NMEA 2000 adapter into the HS70 and
then attach a standard NMEA 2000 dropline cable to the adapter.
Insert the 12-pin connector of the adapter into the male end of the 12-pin connector on the
HS70 by aligning the keys. Secure the adapter to the unit using the supplied screws (machine,
8-32, ½", PPHC, SS) and washer (washer, flat, #8, SS).
Refer "PGNs with the HS70 in NMEA 2000 mode" on page 15.
NMEA 0183
The HS70 offers position, heading, rate of turn, heave, time COG and SOG data, via NMEA
0183 port. In addition to outputting data, these ports are used for firmware upgrades.
Refer "NMEA 0183 messages" on page 18.
Powering the HS70 when used in a NMEA 0183 installation
For best performance use a clean and continuous power supply. The HS70 power supply
features reverse polarity protection but will not operate with reverse polarity.
See "Power specifications" on page 13 for complete power specifications.
Before you power up the HS70 you must terminate the wires of the power cable as required.
There are a variety of power connectors and terminals on the market from which to choose,
depending on your specific requirements.
Warning: Do not apply a voltage higher than 36 VDC. This will damage the receiver
and void the warranty.
To interface the HS70 power cable to the power source:
•
Connect the red wire of the cable's power input to DC positive (+)
•
Connect the black wire of the cable's power input to DC negative (-)
The HS70 will start when an acceptable voltage is applied to the power leads of the extension
cable.
The HS70's power supply is isolated from the communication lines and the PC-ABS plastic
enclosure isolates the electronics mechanically from the vessel (addressing the issue of vessel
hull electrolysis).
