Appendix B: Using the Auxiliary Junction Box
The SeaTalk Auxiliary Junction Box is used to connect SeaTalk GPS and
Differential beacon receivers to your HSB Series Chartplotter or Combined
Fishfinder/Chartplotter.
Note: With the exception of the Raystar 114, when you use the following Dif-
ferential Beacon Receiver configurations, the receiver must be set to AUTO
MODE in the GPS Set-Up page. Manual selections will not be accepted. Refer
to Chapter 6 for details.
The recommended method of providing position, course over ground and
speed over ground information to the HSB displays is by connection to a
SeaTalk GPS. The HSB series chartplotter displays are supplied with an
Auxiliary Junction Box, whose main purpose is to make this connection easier.
The junction box has two flying leads, one with a SeaTalk plug for connection
to the display and the other lead is for connection to a 12V power supply (the
display does not provide power for the GPS).
The following sections detail the connections to the Auxiliary Junction Box for
several different types of GPS, including a beacon receiver if installed. Except
for Raystar 114, the differential beacon receivers used are Raytheon NRD-2A,
Apelco BR101 and the Autohelm Beacon Receiver.
The connections detailed in the following sections ensure that the GPS will
always operate in SeaTalk mode. Note that the Raystar 112LP must be the
SeaTalk version.
