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
INSTANCE” and press O
K.
The default system instance number is “00”. Use the numeric
keypad to enter the required system instance number and press
O
K to confirm (Fig 8.16).
The display will show “SELECTED” and the entered system
number for 2 seconds, then exit to the SimNet management
menu.
