6.27.1.2Installation 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.
6.27.1.3NMEA2000 PGN Enable/Disable
The TMP100 Temperature Module transmits a number of the NMEA2000® PGNs which can be turned on or turned off by the DSM250 display. For reasons of compatibility with older NMEA2000 devices, some of these PGNs are redundant; disabling these PGNs will reduce the amount of traffic on the NMEA2000® bus. Pressing the Enter key with “NMEA2000 PGN Enable/Disable…” menu item selected causes the DSM250 to display the following screen (Figure 214).
Figure 214 – TMP100 NMEA 2000® PGN Enable/Disable Screen
You can enable or disable the transmission of a PGN message, or set the frequency of transmission of the message by pressing the Enter key ( 
) on the message to be configured. Options are:
Off – The PGN will not be transmitted
On – The PGN will be transmitted at its default NMEA2000 rate. 0.5s…5s – The PGN will be transmitted at the interval specified.
Select the required option using the Scroll Up and Scroll Down keys followed by the Enter key.
