PGN 130314 – Actual Pressure
The CLM100 uses this PGN to provide a regular transmission of various temperatures. The
factory default for periodic transmission rate is once every two seconds. The transmission of this
PGN can be disabled (see PGN 126208 – NMEA Request Group Function – Transmission
Periodic Rate).
Field 1:SID – The sequence identifier field is used to tie related PGNs together (i.e., the data
from each PGN was taken at the same time although they are reported at slightly
different times).
2: Pressure Instance – The CLM100 sets this field to identify a particular pressure
measurement from the source specified in Field 3. Every pressure measurement from
a given source type on the network should have a distinct instance value, so that
monitoring devices and displays can identify which measurement is which.
3: Pressure Source – This field is used to indicate the type of pressure measurement
being taken. Possible values for this field include Atmospheric Pressure, Water
Pressure, Steam Pressure, Compressed Air Pressure, Hydraulic Pressure, and 16
User Defined pressure sources.
4: Pressure – This field is used to indicate the pressure, whose source is specified in
field 2, in units of 0.1 Pa.
5: Reserved bits – The CLM100 sets all bits in this field to a value of "1".
PGN 130316 –Temperature, Extended Range
The CLM100 uses this PGN to provide a regular transmission of various temperatures. The
factory default for periodic transmission rate is once every two seconds. The transmission of this
PGN can be disabled (see PGN 126208 – NMEA Request Group Function – Transmission
Periodic Rate).
Field 1: SID – The sequence identifier field is used to tie related PGNs together (i.e., the data
from each PGN was taken at the same time although they are reported at slightly
different times).
2: Temperature Instance – The CLM100 sets this field to identify a particular temperature
measurement from the source specified in Field 3. Every temperature measurement
from a given source type on the network should have a distinct instance value, so that
monitoring devices and displays can identify which measurement is which.
3: Temperature Source – This field is used to indicate the type of temperature
measurement being taken. Possible values for this field include Sea Temperature,
Outside Temperature, Inside Temperature, Engine Room Temperature, Main Cabin
Temperature, Live Well Temperature, Bait Well Temperature, Refrigeration
Temperature, Heating System Temperature, Freezer Temperature, and Exhaust Gas
Temperature.
4: Actual Temperature – This field is used to indicate the temperature, whose source is
specified in field 2, in units of 0.001°C.
5: Set Temperature – The CLM100 sets this field to a value indicating "data not
available".
PGN 130840 – Generic Sensor
The CLM100 uses this PGN to provide a regular transmission of various parameters. The factory
default for periodic transmission rate is once every two seconds. The transmission of
