3 Configuring the FPM100
The FPM100 has several configurable parameters, which are shown below including the
default values. If you are not using the default values, then you will need to refer to the
corresponding section for configuring the FPM100 appropriately.
1. Channel Mode (Section 3.1)
2. Pressure/Vacuum Mode Configuration
a. Instance (Section 3.2.1)
b. Label (Section 3.2.2)
c. Pressure at 4mA (Section 3.2.3)
d. Pressure at 20mA (Section 3.2.4)
e. Source (Section 3.2.5)
f. Data Damping Period (Section 3.2.6)
3. Tank Mode Configuration (Section 3.3)
a. Label (Section 3.3.1)
b. Pressure at 4mA (Section 3.3.2)
c. Pressure at 20mA (Section 3.3.3)
d. Tank Capacity (Section 3.3.4) – Default is No Tank Capacity Transmitted
e. Tank Depth or Custom Calibration (Section 3.3.5)
f. Data Damping Period (Section 3.3.8) – Default is 15 seconds
g. Tank Type (Section 3.1) – Default is Fuel
h. Tank Number (Section 3.3.6) – Default is Tank 0
3.1 Configuring Channel Mode
The FPM100 has 6 individually configurable channels. Each channel can be programmed to
operate in one of three modes:
1. Pressure/Vacuum Mode – In this mode, the FPM100 measures and transmits
pressure and/or vacuum directly over the NMEA 2000 network
2. Tank Mode – In this mode, the FPM100 measures pressure and uses information
about the tank dimensions and the type of fluid in the tank to calculate a tank level,
which is transmitted over the NMEA 2000 network
3. Disable – The channel is disabled and transmits no data over the NMEA 2000 network
The Disable mode requires no configuration. The following sections describe in detail the
configuration of an FPM100 channel for Pressure/Vacuum Mode and in Tank Mode.
3.2 Configuring a Channel in Pressure/Vacuum Mode
The following sections describe the parameters that are available for configuration for a
channel which has been set to Pressure/Vacuum mode.
3.2.1 Configuring Instance
Program this parameter to match the desired instance number of the pressure reading for this
channel. You can program this parameter to any value between 0 and 252.
