6.17.1.3 Installation Description
This entry allows you to modify the NMEA 2000 installation description text strings. You can enter
any information you like here, such as the date the unit was installed, or the location in which it was
installed, for later reference. Tools such as Maretron N2KAnalyzer allow you to view these values
later. See section 3.3.4 for details on how to enter a textual value.
6.17.1.4 J1939 Diagnostic Messages
The J2K100 can optionally pass through J1939 diagnostic messages, used to indicate fault conditions
on engines and transmissions, from the J1939 interface to the NMEA2000
®
network so that NMEA
2000
®
connected displays can interpret these diagnostic codes. To change the transmission status of
the J1939 diagnostic messages, use the Scroll Up ( ) or Scroll Down ( ) keys to move the
highlighted cursor to the “J1939 Diagnostic Messages:” menu item. Then, press the Enter key (
)
to move the highlight to the value field, which displays either Enable or Disable. Use the Scroll Up (
) or Scroll Down ( ) keys to change the value to the desired value, and then press the Enter
key ( ) to accept the new value and store it within the J2K100.

6.17.1.5 Request Engine Hours
Some engines do not transmit their engine hours over the J1939 bus without receiving a request for
engine hours from another device on the J1939 network. If there is no other device to request the
engine hours from these engines, then you will not be able to see engine hours on NMEA 2000
displays. Setting this parameter to “Enable” will case the J2K100 to periodically transmit a request for
engine hours to the engine, allowing the engine hours to be seen on the NMEA 2000 network and
connected displays.
