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. 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.

Figure 2 – NMEA 2000® Connector Face Views

 

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).

 

 

 

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.

 

Warning-Symbol.png

 

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)

 

Warning-Symbol.png

 

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.

 

Figure 4 – Ring/Under Bolt, Ambient Air, or Immersion Temperature Probe Connection Diagram

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.

 

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.

 

Warning-Symbol.png

 

NOTE

 

In order to configure the TMP100, you will need one of the following:

 

·         A Maretron DSM150 or DSM250 display, or

·         Maretron’s N2KAnalyzer® software running on a Windows PC interfacing to the NMEA 2000 network through either:

o   a Maretron USB100 NMEA 2000/USB Gateway, or

o   a Maretron IPG100 Internet Protocol Gateway.

 

Please refer to the user’s manual for the configuration tool you are using for details on how to configure the TMP100 with that product.

 

 

 

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 Temperature, Inside Temperature, Engine Room Temperature, Main Cabin Temperature, Live Well Temperature, Bait Well Temperature, Refrigeration Temperature, Heating System Temperature, Freezer Temperature, Exhaust Gas Temperature, and User Defined Temperature #129-#144. You may also disable the channel by programming the “Disabled” value into this field.

 

2.5.2     Channel #2 - #5 Source

You must configure the TMP100 as to what type of temperature measurement it is transmitting. Possible values for channels 2, 3, 4, and 5 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 User Defined Temperature #129-#144 (please note that Exhaust Gas Temperature is not available on channels 2, 3, 4, and 5). You may also disable the channel by programming the “Disabled” value into this field.

 

2.5.3     Channel #0 - #5 Instance

Each temperature measurement with a given source must have a unique instance number associated with it. This enables monitoring software and displays to distinguish different temperature measurements from one another.  For example, if a channel is programmed to transmit a source type of Exhaust Gas Temperature and the instance for that channel is set to a value of 0, then no other Exhaust Gas Temperature measurement on the network may use an instance number of 0.

 

2.5.4     Channel #0 - #5 Label

Each channel that can be monitored by the TMP100 may be programmed with a text label that will be displayed in monitoring software and displays that recognize device labels, such as the Maretron N2KView Vessel Monitoring System and the Maretron DSM250 display. The label will let you assign an easy-to-remember text label (example: “Forward Bilge Pump”) to make it easy for you to identify the device as you are configuring the monitoring software or display, as well as when alerts are generated.

 

2.5.5     Device Label

This entry allows you to assign a text label to the device. This label is visible in Maretron analysis and display products and allows you to easily identify the particular device.

 

2.5.6     Advanced Configuration…

Certain parameters do not normally need to be set in order for normal operation, but are included in an advanced configuration section for use in special situations.

 

2.5.6.1    NMEA 2000® PGN Enable/Disable

The TMP100 is capable of transmitting NMEA 2000® messages (or PGNs) associated with monitored switch circuits. You may individually enable or disable each of these messages. You may also change the rate of transmission of each of these messages if desired.

 

2.5.6.2    Restore Factory Defaults

Selecting this configuration option causes all stored parameters in the TMP100 to be reset to the values they contained when the unit was manufactured.

 

2.5.6.3    Installation Description…

The TMP100, along with all other Level A certified NMEA 2000 devices, has two user-programmable installation description fields. You may program these fields with information specific to the device, such as date installed, the initials/name of the installer, the physical location of the device, etc.  This configuration option will allow you to program the values of these fields.

Appendix A – NMEA 2000® Interfacing

 

TMP100 NMEA 2000® Periodic Data Transmitted PGNs

 

PGN 130310 – Environmental Parameters (not recommended for new designs; included for backward compatibility)

The TMP100 uses this PGN to provide a regular transmission of water temperature and outside air temperature. The factory default for periodic transmission rate is twice per second. 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. For example, the TMP100 will transmit identical SIDs for 130310 (Environmental Parameters) and 130312 (Temperature) to indicate that the readings are linked together (i.e., the data from each PGN was taken at the same time although they are reported at slightly different times).

           2:    Water Temperature – This field is used to indicate water temperature in units of 0.01°C.

           3:    Outside Ambient Air Temperature – This field is used to indicate the outside ambient air temperature in units of 0.01°C.

           4:    Atmospheric Pressure – This field is filled by the TMP100 with a value indicating “data not available”.

           5:    Reserved bits – The TMP100 sets all bits in this field to a value of “1”.

 

PGN 130311 – Environmental Parameters (not recommended for new designs; included for backward compatibility)

The TMP100 uses this PGN to provide a regular transmission of outside temperature, relative humidity, and atmospheric pressure. The factory default for periodic transmission rate is twice per second. 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. For example, the TMP100 will transmit identical SIDs for 130311 (Environmental Parameters) and 130312 (Temperature) to indicate that the readings are linked 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 TMP100 sets this field to indicate the type of temperature reading. The value of this field depends on the setting of the temperature source for each channel. This value can be any of Sea Temperature, Outside Temperature, Inside Temperature, Engine Room Temperature, or Main Cabin Temperature.

           3:    Humidity Instance – The TMP100 sets this field to a value indicating “data not available”.

           4:    Temperature – This field is used to indicate the temperature, whose source is specified in field 2, in units of 0.01°C.

           5:    Humidity – The TMP100 sets this field to a value indicating “data not available”.

           6:    Atmospheric Pressure – The TMP100 sets this field to a value indicating “data not available”.

PGN 130312 –Temperature (not recommended for new designs; included for backward compatibility)

The TMP100 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. For example, the TMP100 will transmit identical SIDs for 130312 (Temperature) and 130311 (Environmental Parameters) to indicate that the readings are linked 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 TMP100 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, Dew Point Temperature, Apparent Wind Chill Temperature, Theoretical Wind Chill Temperature, Heat Index Temperature, Freezer Temperature, Exhaust Gas Temperature, and User Defined #129-#144.

           4:    Actual Temperature – This field is used to indicate the temperature, whose source is specified in field 2, in units of 0.01°C.

           5:    Set Temperature – The TMP100 sets this field to a value indicating “data not available”.

           6:    Reserved bits – The TMP100 sets all bits in this field to a value of “1”.
