for Connection to TMP100
Maretron TR3K TMP100/DCM100
Ring/Under Bolt Temperature Probe
Instructions
Please follow these instructions to connect the TR3K to the
NMEA 2000® network via a Maretron TMP100 Temperature Module. The wiring
diagram appears in Figure 1 below. The diagram shows a connection to channel #2,
but connections to other channels are similar. Please note that the TR3K may be
connected only to channels #2, #3, #4, and #5. It may not be connected to
channels #0 and #1.
1. Place
a bolt through the 5/16” (7.94mm) hole in the TR3K and secure it to the object
whose temperature is being measured.
2. The
TR3K cable is 10 ft. (3.05m) long, and contains one red and one black wire. The
cable may be extended with the understanding that the TR3K uses a 3KΩ
nominal thermistor, and that the resistance of the extension cable will
introduce an error which is largest at higher temperatures. Connect the black
wire to the appropriate Tx-
terminal on the TMP100 as shown in Figure 1 below.
3. Connect
the red wire to the appropriate Tx+ terminal on the TMP100 as shown in Figure 1 below.
4. Use
a DSM250 (firmware 1.3.8 or greater) or other Maretron display product capable
of configuring the TMP100 to configure the “Channel #x Source” to the type of temperature you are measuring.
5. Use
a DSM250 (firmware 1.3.8 or greater) or other Maretron display product capable
of configuring the TMP100 to set the Configure the “Channel #x Instance” to a number that is unique
across the network for the source you have selected. In other words, if you are
measuring Freezer Temperature, there may be only one channel on the network
that measures Freezer Temperature that has an instance number of 0. Number
further Freezer Temperature channels as instance #1, #2, and so on.
6. If
desired, use DSM250 (firmware 1.3.8 or greater) or other Maretron display
product capable of configuring the TMP100 to configure the “Channel #x Label” to a text string that allows
you to identify the particular temperature that is being measured by this
probe. For example, if you have two freezers, you may wish to label one of them
“Port Freezer” and the other “Starboard Freezer”.
7. Using
a Maretron DSM250 or Maretron N2KView, show the temperature with the source and
instance you have selected and verify that you see a valid temperature on the
display.

Instructions
for Connection to DCM100
Maretron TR3K TMP100/DCM100
Ring/Under Bolt Temperature Probe
Instructions
Please follow these instructions to connect the TR3K to the
NMEA 2000® network via a Maretron DCM100 DC Monitor. The wiring
diagram appears in Figure 1 below.
1. Place
a bolt through the 5/16” (7.94mm) hole in the TR3K and secure it to the battery
case whose temperature is being measured.
2. The
TR3K cable is 10 ft. (3.05m) long, and contains one black and one red
wire. The cable may be extended with the
understanding that the TR3K uses a 3KΩ nominal thermistor, and that the
resistance of the extension cable will introduce an error which is largest at
higher temperatures. Connect the red wire to the TA terminal on the TMP100 as
shown in Figure 1 below.
3. Connect
the black wire to the TB terminal on the DCM100 as shown in Figure 1 below.
4. Use
a DSM250 (firmware 1.3.5 or greater) or other Maretron display product capable
of configuring the DCM100 to configure the “Battery Temperature” parameter to
the value of “Sensor”.
5. Using
a Maretron DSM250 or Maretron N2KView, show the battery
temperature with the instance you have selected and verify that you see a valid
temperature on the display.
