6.17.1.6 Restore Factory Defaults

This option restores all settings on the device to their factory default state.

6.17.2 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.

6.17.3 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 136 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 6.17.4) identifies the engine on the

J1939 network, the Engine Instance indentifies the engine to the NMEA2000 network.
