Configuring an Optional Wired NRX Remote Control
NOTICE
The stereo is configured by default to work with a Garmin Controller Area Network (Garmin CAN), and the NRX
POWER option should be enabled only when an optional wired NRX remote control is connected directly to the
stereo. Enabling this option when the stereo is connected to a CAN bus may damage other devices on the
network.
If you connect an optional wired NRX remote control directly to the stereo, and not through Garmin CAN,
additional configuration is needed.
1 Select
> SETTINGS > POWER OPTIONS.
2 Select an option:
• If you connected both your stereo and your optional wired remote to a Garmin CAN bus, make sure the
NRX POWER option is not selected. This enables the optional remote to receive power from the Garmin
CAN bus.
• If you connected the optional wired remote directly to the stereo through the NMEA 2000 connector,
select the NRX POWER option. This enables the stereo to supply power to the optional remote.
EmpirBus Web Display Unit
This device is capable of acting as an EmpirBus Web Display Unit (WDU). A complete EmpirBus system
requires one or more display products and one or more digital switching modules (sold separately). Refer to the
installation documents for those products to plan and install your system. Connect all displays to the Apollo
RV-RA770 device using a wireless network or a wired network. Connect all modules to the Apollo RV-RA770
device using a Garmin Controller Area Network (
System Wiring Diagram, page 14
