Figure 90 – FFM100 NMEA 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.
6.12.1.9 Restore Factory Defaults
This option restores all settings on the device to their factory default state.
6.12.2 Device Label
A label may be assigned to the FFM100 as an aid to identifying the device over the network. Typically this label will describe the location of the FFM100.
6.12.3 Operating Mode
The FFM100 can operate in one of two user-selectable operating modes:
Differential – this mode is used for diesel engines that recirculate unused fuel back into the fuel take.
These engines will have separate supply and return fuel lines.
Two Independent Sensors – the FFM100 can measure flow rates from two independent sources; for example, a water flow rate on one channel and a gasoline fuel flow rate on another channel.
6.12.4 Channel #0…
This submenu contains configuration parameters for Channel #0. This menu looks different depending on whether the FFM100’s operating mode has been set to “Differential” or “Two
Independent Sensors”.
