Using the SeaTalk Auxiliary Junction Box
A junction box (provided with the radar/chart and chart displays; optional
with the radar displays) is used to connect the SeaTalk system to the
hsb
2
series
display unit. This junction box enables the SeaTalk bus, power and GPS to be
connected.
If power is not already available (via another SeaTalk instrument), the
junction box can be used to apply power to the SeaTalk bus for other
applications. The junction box may also be used for other purposes, e.g.
supplying power to a flux gate compass and routing the compass data to the
hsb
2
series display NMEA In connection, or alternatively, for connecting a
NMEA GPS system.
The junction box includes:
•
SeaTalk cable and connector to attach to display unit
•
Power cable to connect to 12 V power (if required)
•
Input connections to connect SeaTalk cable from external equipment
•
Spare connections for another instrument
CAUTION:
Ensure correct polarity of the 12 V supply before applying radar or
SeaTalk power. It is recommended that a multimeter is used to check the
connections.
Figure 8-18
shows how to connect the junction box;
Appendix B
provides
connection details for specific GPS and Beacon Receiver systems.
