Maretron TMP100 Exhaust Gas Temperature Probe TP-EGT-1 - Manual (Page 10)

TMP100 User's Manual
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
