2.5.1 Instance Selection
NMEA 2000
®
provides a unique engine instance for each DC power source on a vessel. You
configure the DCM100 using a Maretron DSM250 display or other NMEA 2000
®
display unit
that is capable of configuring the DCM100. Please refer to the Maretron
DSM250 User’s
Manual
for details.
2.5.2 Priority Selection
NMEA 2000
®
can provide a unique priority for allowing multiple, redundant sensors for a single
DC power source on a vessel. If you have only on DCM100 on a particular DC power source,
you should leave the priority selection at the default value of zero. You configure the DCM100
using a Maretron DSM250 display or other NMEA 2000
®
display unit that is capable of
configuring the DCM100. Please refer to the Maretron
DSM250 User’s Manual
for details.
2.5.3 DC Type
You can configure the DCM100 as to what type of DC power source it is monitoring. With the
exception of the “Battery” type, the value of this parameter is used only for reporting the power
source type over the NMEA 2000 network. However, if you select the “Battery” type, many
battery-related options become available. You configure the DCM100 using a Maretron
DSM250 display or other NMEA 2000
®
display unit that is capable of configuring the DCM100.
Please refer to the Maretron
DSM250 User’s Manual
for details.
The following DC Types are selectable:
- Battery (See Section 2.5.4 for options that are enabled when this type is selected)
- Alternator
- Convertor
- Solar
Cell
- Wind
Generator
2.5.4 Battery-Specific Options
The options in this section are available only if the “DC Type” parameter is set to “Battery”.
2.5.4.1 Battery Type
The available battery types are “Flooded/Wet”, “Gel”, “AGM”, and “Other”. Selecting one of
these types causes the remaining parameters to be set to appropriate default values.
2.5.4.2 Nominal Voltage
You may program here the nominal voltage of the battery, which is used only for reporting over
the NMEA 2000 network. Available choices are 6, 12, 24, 32, 36, 42, and 48 Volts.
