Use the Scroll Up (
) or Scroll Down ( ) keys to change the value to the desired value you wish
to use as the transmission instance identifier, and then press the Enter key ( ) to accept the value
and store it within the J2K100.
6.17.5 AC/Icemaker Instance
This entry allows a air conditioner or icemaker to be mapped to an NMEA2000 instance number.
Each air conditioner or icemaker on an NMEA 2000
®
network must have a unique instance identifier,
to allow display devices to distinguish it from other air conditioners or icemakers on the network. The
“AC/Icemaker:” menu item allows you to configure the air conditioner or instance identifier which will
be sent over the NMEA 2000
®
network along with air conditioner or icemaker-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 “AC/Icemaker:” menu item. Then, press the Enter key (
) to
move the highlight to the numeric value on the right, as shown in Figure 136 below. Because only one
such mapping can take place, each air conditioner or icemaker on the J1939 network must have its
own J2K100 Gateway. The J1939 Source Address (see section 6.17.4) identifies the air conditioner
or icemaker on the CAN network, the AC/Icemaker Instance indentifies the air conditioner or
icemaker to the NMEA2000 network.

Use the Scroll Up (
) or Scroll Down ( ) keys to change the value to the desired value you wish,
and then press the Enter key ( ) to accept the value and store it within the J2K100.
6.17.6 J1939 Source Address Configuration
A J1939 engine/genset and transmission has its own source address on the J1939 network, which is
different from NMEA 2000
®
addresses. The J2K100 is capable of serving as a gateway between a
single J1939 engine/genset or a single transmission and the NMEA 2000
®
network. This setting
identifies the J1939 source address of the engine/genset and a transmission for which the J2K100
will serve as a gateway.
For air conditioners or icemakers, the “J1939 source address” refers to the source address of the air
conditioner or icemaker on the AC/Icemaker CAN network.
