1 Introduction
Congratulations on your purchase of the Maretron Temperature Module. Maretron has
designed and built your TMP100 to the highest standards for years of dependable and
accurate service.
Maretron's TMP100 measures the temperature for up to 6 temperature probes and reports the
information over an NMEA 2000®network. The TMP100 supports up to 4 thermistor probes
and 2 high temperature thermocouple probes. Optional thermistor probes (-20°C to 80°C or -
4°F to 176°F) cover a wide range of applications including cabin air temperature, engine room
air temperature, refrigerator/freezer temperature, under bolt temperature (inverters, charges,
pumps, motors, etc.), tank temperatures (live well bait, hot water, etc.), and air duct
temperatures. The optional thermocouple probes (0°C to 900°C or 32° to 1652°F) are used to
measure Exhaust Gas Temperature (EGT) as part of a comprehensive fuel management
system.
The Maretron TMP100 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 TMP100 in order to
ensure optimal performance.

1.4 Quick Install
Installing the Maretron TMP100 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 TMP100 (Section 2.3)
4. Connect the TMP100 (Section 2.4)
5. Configure the TMP100 (Section 2.5)
2 Installation
2.1 Unpacking the Box
When unpacking the box containing the Maretron TMP100, you should find the following items:
1 – TMP100 – Temperature Module
1 – Parts Bag containing 4 Stainless Steel Mounting Screws
1 – TMP100 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
Please consider the following when choosing a mounting location.
1. The TMP100 is waterproof, so it can be mounted in a damp or dry location.
2. The orientation is not important, so the TMP100 can be mounted on a horizontal deck,
vertical bulkhead, or upside down if desired.
3. The TMP100 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 TMP100
Attach the TMP100 securely to the vessel using the included stainless steel mounting screws
or other fasteners as shown in Figure 1 below.
Figure 1 – Mounting the TMP100
2.4 Connecting the TMP100
The TMP100 requires two types of electrical connections: 1) the NMEA 2000®connection
(refer to Section 2.4.1), and 2) the temperature probe connections, which are described in
Section 2.4.2.
2.4.1 NMEA 2000®Connection
The NMEA 2000®connector can be found on the side of the enclosure. The NMEA 2000®
connector is a round five pin male connector (see Figure 2). You connect the TMP100 to an
NMEA 2000®network using a Maretron NMEA 2000®cable (or compatible cable) by
connecting the female end of the cable to the TMP100 (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 TMP100 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 Temperature Probe Connections
The TMP100 temperature probe 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 detaching
the splash guard from 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 # Signal Name Connection
1 T0+ Exhaust Gas Temperature Probe 0 (positive terminal)
2 T0- Exhaust Gas Temperature Probe 0 (negative terminal)
3 T1+ Exhaust Gas Temperature Probe 1 (positive terminal)
4 T1- Exhaust Gas Temperature Probe 1 (negative terminal)
5 T2+ Temperature Probe 2 (positive terminal)
6 T2- Temperature Probe 2 (negative terminal)
7 T3+ Temperature Probe 3 (positive terminal)
8 T3- Temperature Probe 3 (negative terminal)
9 T4+ Temperature Probe 4 (positive terminal)
10 T4- Temperature Probe 4 (negative terminal)
11 T5+ Temperature Probe 5 (positive terminal)
12 T5- Temperature Probe 5 (negative terminal)
Before attempting to connect the TMP100 to the temperature probes, determine the type of
system you will be monitoring. The TMP100 supports the connection and monitoring of two
different system types; 1) Exhaust Gas Temperature probes (Section 2.4.2.1), or 2) thermistor
type probes (ring/under bolt probes, immersion probes, and ambient air probes; please see
Section 2.4.2.2).

2.4.2.1 Exhaust Gas Temperature (EGT) Probe
The TP-EGT-1 exhaust gas temperature probe may be used to measure temperatures other
than exhaust gas temperatures; however, the TP-EGT-1 exhaust gas temperature probe is the
only TMP100 temperature probe that has sufficient range to measure exhaust gas
temperature.
NOTE: You may connect TP-EGT-1 exhaust gas temperature probes only to the terminal pairs
T0+/T0- (pins 1 and 2) or T1+/T1- (pins 3 and 4).
Please refer to Figure 3 for connecting the TMP100 to an TP-EGT-1 exhaust gas temperature
probe. Please be sure to connect the red wire from the EGT probe to the negative “-“ terminal,
and the yellow wire from the EGT probe to the positive “+” terminal. This figure shows the
connection of the exhaust gas temperature probe temperature channel 0 via the terminals
named T0+ and T0-. Connection to channel 1 is similar.

2.4.2.2 Thermistor Type Probes (Ring/Under Bolt, Ambient Air, or Immersion Probe)
NOTE: You may connect TR3K ring/under bolt,TP-AAP-1 ambient air, and TP-IP-1 immersion
probes only to the terminal pairs T2+/T2- (pins 5 and 6), T3+/T3- (pins 7 and 8), T4+/T4- (pins
9 and 10), or T5+/T5- (pins 11 and 12).

Please refer to Figure 4 for connecting the TMP100 to a TR3K ring/under bolt thermistor
temperature probe, TP-AAP-1 ambient air temperature probe, or TP-IP-1 immersion
temperature probe. This figure shows the connection of the TP-IP-1 immersion probe to
channel 2 via the terminals named T2+ and T2-, the TR3K ring/under bolt probe to channel 3
via the terminals named T3+ and T3-, and the TP-AAP-1 ambient air probe to channel 4 via
the terminals named T4+ and T4-. Connection to channel 5 is similar.

2.4.3 Checking Connections
Once the NMEA 2000® connection and temperature probe connection(s) to the TMP100 have
been completed, check to see that information is being properly transmitted by observing an
appropriate NMEA 2000®display. If you don’t see temperature indications, refer to Section 4,
“Troubleshooting”.
2.5 Configuring the TMP100
The TMP100 will transmit data over the NMEA 2000®network as it is shipped from the factory;
however, it may require configuration, depending on the types of temperature measurements
you are making. There are several configurable items within the TMP100, which are detailed in
the remainder of this section.
You configure the TMP100 using a Maretron DSM250 display or other NMEA 2000®display
unit that is capable of configuring the TMP100. Please refer to the Maretron DSM250 User’s
Manual for details.
2.5.1 Channel #0 - #1 Source
You must configure the TMP100 as to what type of temperature measurement it is
transmitting. Possible values for channels 0 and 1 include Sea Temperature, Outside
