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.
6.17.4 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. Th
e “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 below. Because only one such mapping can
take place, each Transmission and each Engine on the J1939 network must have its own J2K100
Gateway. The J1939 Source Address (see section 6.17.4) identifies the transmission on the J1939
network, the Transmission Instance indentifies the transmission to the NMEA2000 network.
