6.13.2.2.4 Pressure at 4mA
Enter the pressure measured by the pressure sensor when it is outputting a 4mA current (this will
usually be zero).
6.13.2.2.5 Pressure at 20mA
Enter the pressure measured by the pressure sensor when it is outputting a 20mA current.
6.13.2.2.6 Source
In the NMEA2000
®
PGNs, each pressure is associated with a source type. Possible values are:
Water Pressure
Atmospheric Pressure
Compressed Air Pressure
Hydraulic Pressure
Steam Pressure
User Defined Temperature #129...#144 – Use this when none of the above options are suitable.
6.13.2.2.7 Data Damping Period
If the channel’s Function is set to Tank, the default data damping period is 16.0 seconds. If the
channel’s Function is set to Pressure/Vacuum, the default data damping period is 3.0 seconds.
6.14 Maretron GPS100 Configuration
This describes the configuration of the Maretron GPS100 firmware version 1.0.6. Some versions of
the GPS100 have a different set of firmware that is currently at version 1.6.14. The configuration of
these devices is identical to version 2.0.1 shown here. The GPS100 has several different
programmable parameters that are configurable by the DSM250 display. Normally, it is not necessary
to configure the GPS100 although there may be some circumstances where configuration is
desirable. The following sections describe the different configuration modes including the “Restore
Factory Defaults” configuration, which allows you to return the GPS100 to the factory settings.
