9-8
NETWORK INTERFACE MODULE (NIM)
The optional NIM board is mounted on the side of
the genset (Figure 9-1) and is connected as shown
on Page A-1. It has five jumpers to configure the
board for the specific application (Figure 9-6). Make
sure a replacement board is configured the same as
the old one.
Note: For SAE J1939 applications, see Onan Publica-
tion D-3315, Supported Messages on SAE J1939.
This is the basis for the software interface between
the genset controller and the remote boat monitor.
Note: For SmartCraft
applications, see your Cum-
mins MerCruiser Distributor for more information.
1. Jumper W1 has no function at this time.
2. Jumper W2 will be cut when the genset is in an
SAE J1939 network application. The jumper
must remain uncut when the genset is in a
SmartCraft network application.
3. Jumpers W3 and W4 are used to assign the
J1939 network address of the genset in a multi-
ple-genset installation. To assign an address,
cut the jumpers as scheduled in Table 9-1.
In SmartCraft applications, see your Cum-
mins MerCruiser Distributor.
