If your device is behaving erratically even after following this guide, the issue may be hardware-related (failing capacitors or backlight inverter). In that case, the manual will not help—consider a repair shop, as the cost of repairing an 18-inch TV often exceeds its value.
. To retrieve data, a master device (like a PLC or PC) sends specific function codes to target registers: Read the Docs Temperature Data : Registers store the current temperature for each of the 7 channels. : Register
Press again or wait 5 seconds without pressing anything to save the value. Accessing Advanced System Parameters (P-Menus)
To ensure accurate readings and device longevity, follow these wiring standards: nt18b07 manual
Before operating the NT18B07, always prioritize safety to prevent accidental discharge or injury:
Insert a strip of brad nails into the side of the magazine. Ensure the points are facing downward.
For industrial environments with high electromagnetic noise, ensure the FE (Functional Earth) terminal is properly grounded to prevent communication errors. Configuration Examples If your device is behaving erratically even after
The NT18B07 is a versatile and cost-effective solution for digitizing multiple NTC temperature sensors. As this manual has demonstrated, it can be used in a wide array of applications, from professional industrial automation with PLCs to custom DIY IoT data loggers using the ESP32 platform.
: 9600 Baud Rate, No Parity (N), 8 Data Bits, 1 Stop Bit ( 9600, N, 8, 1 ).
To prevent address conflicts on a multi-device RS485 network, you can change the NT18B07's Slave ID. This is done by writing a new value (1-247) to MODBUS Holding Register 254, using the Write Single Register (0x06) function code. To retrieve data, a master device (like a
Weight increases to ~40g when packaged with standard sensor kits. Hardware Pinout & Wiring Configurations
Note: This layout assumes you are using a 12V DC variant of the NT18B07 to switch an AC load.
Temperature readings gathered from registers 0 through 6 are transmitted as fixed-point integers scaled by a factor of 10. To find the true temperature in degrees Celsius, you must divide the returned value by 10.
Using standard XH2.54-2P connectors, plug your into the respective channel headers. Because NTC thermistors are non-polarized resistors, the orientation of the two-pin plug does not matter. Modbus RTU Protocol & Register Mapping
