1 14Introduction
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

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.

Revision 1.2 Page 3
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. Do not use threadlocking compounds
containing methacrylate ester, such as Loctite Red (271), as they will cause stress cracking of
the plastic enclosure.
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.

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).

Revision 1.2 Page 5
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 a 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 to channel 0 via the terminals
named T0+ and T0-. Connection to channel 1 is similar.
Figure 3 –Exhaust Gas Temperature Probe Connection Diagram
2.4.2.1.1 Cable Extension
If the cable on the EGT probe is not long enough to reach from the probe location back to the
terminals on the TMP100, you may extend the cable using only K-Type thermocouple
extension wire. Other types of extension wire will result in inaccurate temperature readings.

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.

2.4.2.2.1 Cable Extension
If the cable on the thermistor type probe is not long enough to reach from the probe location
back to the terminals on the TMP100, you may extend the cable using ordinary two-conductor
cable with 22AWG or larger conductors. However, extending the cable will add resistance to
the circuit and can result in inaccurate temperature readings if this resistance is too high. For
example, in the worst case, which is measurement of an 80°C temperature, an additional 13Ω
of resistance will result in a -1°C temperature measurement error. To make your own
calculation, please refer to the Maretron Knowledge Base for details on the thermistor type
probe resistance versus temperature curves.
