Raymarine RL70C User Manual

Chapter 8: Installation 167
Using the SeaTalk Auxiliary Junction Box
A junction box (provided with the RL70RC and RC520, optional with the
RL70) is used to connect the SeaTalk GPS system (or any other SeaTalk
instrument) to the HSB 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 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
The illustration below shows how to connect the junction box; Appendix B
provides connection details for specific Raytheon, Apelco and Autohelm GPS
and Beacon Receiver systems.
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.
