Appendix B: Using the Auxiliary Junction
Box
The SeaTalk Auxiliary Junction Box is used to connect SeaTalk GPS and
Differential beacon receivers to your display.
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 displays is by connection to a SeaTalk
GPS. The SL72RC PLUS 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 Raymarine
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.
