Device Label
A label may be assigned to the J2K100 as an aid to identifying the device over the network.
See section 3.3.4 for details on how to enter a textual value.
6.18.3
NMEA 2000 Instance
– Engine
This entry allows the engine to be mapped to an NMEA2000 instance number. Each engine on an
NMEA 2000
®
network must have a unique instance identifier, to allow display devices to distinguish it
from other engines on the network. The “NMEA2000 Engine Instance:” menu item allows you to
configure the engine instance identifier which will be sent over the NMEA 2000
®
network along with
engine-related NMEA 2000
®
messages. In order to configure this parameters, use the Scroll Up (
)
or Scroll Down (
) keys to move the highlighted cursor to the “NMEA2000 Engine Instance:” menu
item. Then, press the Enter key (
) to move the highlight to the numeric value on the right, as
shown in Figure 140 below.
Because only one such mapping can take place, each engine on the J1939 network must have its
own J2K100 Gateway. The J1939 Source Address (see section 6.18.4) identifies the engine on the
J1939 network, the Engine Instance identifies the engine to the NMEA2000 network.

– J2K100 Engine Instance Configuration
Use the
Scroll Up and Scroll Down
keys to change the value to the desired value you wish to use
as the engine instance identifier, and then press the
Enter
key to accept the value and store it within
the J2K100.
6.18.4
Transmission Instance
This entry allows a transmission to be mapped to an NMEA2000 instance number. Each transmission
on an NMEA 2000
®
network must have a unique instance identifier, to allow display devices to
distinguish it from other transmissions on the network. The “NMEA2000 Transmission Instance:”
menu item allows you to configure the transmission instance identifier which will be sent over the
NMEA 2000
®
network along with transmission-related NMEA 2000
®
messages. In order to configure
this parameters, use the Scroll Up (
) or Scroll Down (
) keys to move the highlighted cursor to
the “NMEA2000
Transmission Instance:” menu item. Then, press the Enter key (
) to move the
highlight to the numeric value on the right, as shown in Figure 141 below. Because only one such
mapping can take place, each Transmission and each Engine on the J1939 network must have its
