1 Introduction

Congratulations on your purchase of the Maretron DC Monitor (DCM100). Maretron has designed and built your DC monitor to the highest standards for years of dependable and accurate service.
Maretron’s DCM100 is a device which monitors DC power sources or batteries and outputs information about these sources onto the industry standard NMEA 2000® marine data network so that these data can be monitored with networked NMEA 2000® displays such as the Maretron DSM250 or with NMEA 2000® compatible software such as Maretron N2KView.
The Maretron DCM100 is designed to operate within the harsh demands of the marine environment. However, no piece of marine electronic equipment can function properly unless installed, configured, and maintained in the correct manner. Please read carefully and follow these instructions for installation, configuration, and usage of the Maretron DCM100 in order to ensure optimal performance.

1.1 Firmware Revision

This manual corresponds to DCM100 firmware revision 1.0.2.

1.2 DCM100 Features

The Maretron DCM100 has the following features.
NMEA 2000® Interface
Waterproof Connectors
Sealed Waterproof Enclosure
Opto-Isolated from NMEA 2000® Eliminating Potential Ground Loops
Can monitor DC Power Sources, Transmitting Voltage and Current
Can monitor Lead Acid and Gel Batteries, Transmitting Voltage, Current, Temperature,
and State of Charge
Uses Peukert’s Constant and Charge Efficiency Factor for Accurate State of Charge Calculation
Can Calculate Charge Efficiency Factor Based on Observed Battery Performance

1.3 Quick Install

Installing the Maretron DCM100 DC monitor involves the following five steps. Please refer to the individual sections for additional details.
1. Unpack the box (Section 2.1)
2. Choose a mounting location (Section 2.2)
3. Mount the DCM100 (Section 2.3)
4. Connect the DCM100 (Section 2.4)
5. Configure the DCM100 (Section 2.5)
6. Synchronize the DCM100 with the battery (Section 2.6)

2 Installation

2.1 Unpacking the Box

When unpacking the box containing the Maretron DCM100, you should find the following items:
1 – DCM100 – DC Monitor 1 – DC Current Sensor with 5 ft. long cable (Part # LEMHTA200-S) (outer cable covering grey) 1 – Battery Temperature Sensor with 5 ft. long cable (Part # TR3K) (outer cable covering grey) 1 – Battery Voltage Sense Cable, 5 ft. long (Part # FC01) (outer cable covering white ) 1 – Power Cable, 5 ft. long (Part # FC01) (outer cable covering white) 1 – Parts Bag containing 4 Stainless Steel Mounting Screws 1 – DCM100 User’s Manual 1 – Warranty Registration Card
If any of these items are missing or damaged, please contact Maretron.

2.2 Choosing a Mounting Location

The DCM100 should be mounted near the monitored source of DC power. Please consider the following when choosing a mounting location.
1. The DCM100 is waterproof, so it can be mounted in a damp or dry location.
2. The orientation is not important, so the DCM100 can be mounted on a horizontal deck, vertical bulkhead, or even upside down if desired.
3. The DCM100 is temperature rated to 55°C (130°F), so it should be mounted away from engines or engine rooms where the operating temperature exceeds the specified limit.

2.3 Mounting the DCM100

Attach the DCM100 securely to the vessel using the included stainless steel mounting screws or other fasteners as shown in Figure 1 below.
Figure 1 – Mounting the DCM100

2.4 Connecting the DCM100

The DCM100 requires two electrical connections as shown in . Refer to Section 2.4.1 for making the NMEA 2000® connection and Section 2.4.2 for making the DC monitor connections (i.e., current sensor, sensing voltage, and temperature sensor connections)..

2.4.1 Connecting the DCM100 NMEA 2000® Interface

Vertical text on the DCM100 label identifies the NMEA 2000® connector. With the label right side up, the NMEA 2000 NMEA 2000® connector is a five pin male connector (see Figure 2). You connect the DCM100 to an NMEA 2000® network using a Maretron NMEA 2000® cable (or compatible cable) by connecting the female end of the cable to the DCM100 (note the key on the male connector and keyway on the female connector). Be sure the cable is connected securely and that the collar on the cable connector is tightened firmly. Connect the other end of the cable (male) to the NMEA 2000® network in the same manner. The DCM100 is designed such that you can plug or unplug it from an NMEA 2000® network while the power to the network is connected or disconnected. Please follow recommended practices for installing NMEA 2000® network products.

2.4.2 Connecting the DC power and Sensor Connections

The DCM100’s DC Power and sensor connections are made by connecting to the 12-pin terminal strip on the top of the unit. First, remove the four screws at the corners of the unit securing the splash guard to the unit. On the bottom of the splash guard, you will find a label detailing the wire connection to pin number assignments, which are repeated in the table below.
Pin Number Signal Name Connection
1 IA Current Sensor, Red Wire 2 IB Current Sensor, Green Wire 3 IC Current Sensor, Black Wire 4 ID Current Sensor, White Wire 5 V 6 V 7 V 8 V
9 No Connect 10 No Connect 11 TA Temperature Sender, Red Wire 12 TB Temperature Sender, Black Wire
Step 1: The Current Sensor (LEMHTA200-S) has a gray cable containing red, green, black, and white wires. Install the Current Sensor as follows:
a. Connect the red wire to pin 1 (I b. Connect the green wire to pin 2 (I c. Connect the black wire to pin 3 (I d. Connect the white wire to pin 4 (I
