As a default, the RS82 will give priority to SimNet data over

that received via the NMEA input. This function enables you to

select the NMEA input as the priority data source.

From the SimNet management menu select “DATA SOURCES”

and press OK.

Use the VOL ▲ and VOL ▼ keys to scroll through the following

options -

Simrad Group – (Default) Accept the data source aspecified

by the Group Owner. A Group Owner is a unit capable of dic-

tating which data source other SimNet units on the bus use.

The Group Owner is usually a Chartplotter or similar unit.

NMEA0183 – This option will select the NMEA0183 input as

the nav data source.

SimNet units – The display will show the name and serial

number of each SimNet unit detected on the network.

Third Party units – The display will show the name and ser-

ial number of any third party units connected to the bus via

NMEA2000.

NOTE

Apart from NMEA0183, a maximum of four other sources

will be shown, and these will be the first four detected. Any

further sources apart from these will be ignored.

Press OK to set the selected data source. The display will show

“SOURCE SELECTED”, then exit to the SimNet management

menu.

NOTE

If the selected data source is lost, the radio will automatically

select another SimNet or NMEA source if available, otherwise

the display will show “SOURCE DATA LOST”.

8.3.6.2 Lighting banks

This function allows individual RS80 stations to be assigned to different lighting banks across the SimNet bus. It enables groups of SimNet products to be set up as “zones”, which share the same backlight settings. This is useful on vessels with, for example, an interior and an exterior steering position, where the ambient lighting (and therefore backlighting requirement) is different (Fig 8.13).

FLYBRIDGE (bank 1)

WHEELHOUSE (bank 2)

Fig 8.13 - Example of vessel with two lighting banks

	Thus, on a flybridge cruiser all the equipment fitted on the fly-
	bridge can be assigned to lighting bank 1 and the equipment in
	the wheelhouse can be assigned to lighting bank 2.
	Adjusting the lighting on one unit in bank 1 will be duplicated
	on all other products in the same bank, but will not affect any
	units in bank 2.
	From the SimNet management menu select “LIGHTING
	BANKS” and press OK.
	Use the VOL ▲ and VOL ▼ keys to select the station you want
	to assign to a particular lighting bank.
	Use the numeric keypad to enter the bank number (0–63).
	Press OK to confirm.
	Repeat the above sequence for each station fitted to the RS82.
	Press ON/C to exit to the SimNet management menu.

	possible to split IS12 displays into separate banks.

	8.3.6.4 System instance
	A SimNet bus can have a maximum of 50 devices (or “nodes”)
	attached to it. If a large vessel has a requirement for more than
	50 nodes, then a multiple network system is required.
	The system instance allows the user to allocate a unique num-
	ber to each network, which allows the multiple networks to
	intercommunicate.
NOTE	If your vessel is large enough that it is likely to require setting
	up multiple networks, it is strongly advised that you contact
	Simrad Technical Support to discuss your particular system
	requirements before proceeding further.
	From the SimNet management menu select “SYSTEM

9 DSC FUNCTIONS

9.1 General

	The RS82 features full Class D DSC (Digital Selective Calling)
	functionality enabling the user to make digitally selected calls,
	which are quicker and simpler to make than traditional voice
	calls using channel 16. Should a distress situation occur, a
	Distress Alert call can be initiated, indicating the vessel’s iden-
	tity, position and automatically establish distress communica-
	tion on the emergency voice channel (normally channel 16).
NOTE	DSC functions will only be available, if the MMSI number has
	been entered into the radio (see section 8.2.1).
