Yacht Devices YDTC-13RT Digital Thermometer with SeaTalk NG Connector and Built-In 120 Ohm Terminator, -55 to +125°C
The Yacht Devices YDTC-13RT is a digital marine thermometer designed for precise temperature measurement in SeaTalk NG and NMEA 2000 networks. It measures gases and liquids over a range from -55 to +125°C (-67 to +257°F) and transmits temperature data to compatible chart plotters, digital navigation instruments and other onboard equipment.
The YDTC-13RT version is equipped with a Raymarine SeaTalk NG Female Terminator connector and contains an integrated 120 Ohm termination resistor. It is designed to replace an existing terminator at the end of the NMEA 2000 / SeaTalk NG bus while also providing temperature measurement at the same network connection point.

Built-In SeaTalk NG Terminator
The YDTC-13RT includes a built-in 120 Ohm terminator and must be connected to the network in place of an existing terminator. NMEA 2000 networks use two 120 Ohm terminators installed at the ends of the bus.
- Integrated termination resistance: 120 Ohm
- Designed for installation at the end of the network backbone
- Replaces an existing network terminator
- No more than two devices with built-in termination may be used on one NMEA 2000 bus
Configurable Temperature Types
Type Temperature Data 0 Sea Temperature 1 Outside Temperature 2 Inside Temperature 3 Engine Room Temperature 4 Main Cabin Temperature 5 Live Well Temperature 6 Bait Well Temperature 7 Refrigeration Temperature 8 Heating System Temperature 9 Dew Point Temperature 10 Wind Chill Temperature, Apparent 11 Wind Chill Temperature, Theoretical 12 Heat Index Temperature 13 Freezer Temperature
The factory setting is Outside Temperature.
NMEA 2000 Data Output
The thermometer can transmit measured temperature through several NMEA 2000 PGNs depending on the selected temperature type and the capabilities of the connected display equipment.
- PGN 130310
- PGN 130311
- PGN 130312
- PGN 130316
The periodic transmission interval can be configured from 50 milliseconds to 1 hour. Setting the interval to 0 disables transmission of the selected PGN.
Historical Temperature Data
The device stores measurements from the previous 48 hours in internal RAM. Historical temperature data can be retrieved using compatible software or hardware.
Digital Switching Support
With firmware version 1.50 or later, the YDTC-13RT can control channels of compatible NMEA 2000 digital switching equipment supporting PGN 127502 Switch Bank Control.
- Up to 3 configurable ON rules
- Up to 3 configurable OFF rules
- Switching based on actual measured temperature
- Configurable condition delay
- Can be used for automatic control of compatible pumps, ventilation or alarm systems
Sensor Cable Extension
The standard 950 mm sensor cable can be extended by the user up to 100 meters. A three-conductor extension cable with a conductor cross-section of at least 0.2 mm² and conductor diameter of at least 0.5 mm is recommended.
- Maximum sensor cable extension: 100 m
- Minimum conductor cross-section: 0.2 mm²
- Minimum conductor diameter: 0.5 mm
- Suitable cable categories include UTP 3, UTP 5 and UTP 5e with AWG-24 or AWG-22 conductors
The extended sensor cable should be routed away from strong electromagnetic interference sources such as motors, compressors, generators, electric pumps and transmitting antennas.
Installation
The YDTC-13RT must be installed at the end of the SeaTalk NG / NMEA 2000 bus in place of an existing terminator. The device connects directly to the network without a drop cable, and bus power should be switched off before installation.
The main device should be installed in a dry location. The external stainless-steel sensor sleeve is waterproof, but it is not intended for permanent installation in hostile environments such as seawater.
