Appendix B: Using the Auxiliary Junction Box

The SeaTalk Auxiliary Junction Box is used to connect SeaTalk GPS and Differential beacon receivers to your hsb2 series 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 hsb2 displays is by connection to a SeaTalk GPS. The hsb2 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 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.
