The NT18B07 breaks out its power, serial bus, and sensor interfaces across dedicated terminal blocks. Proper wiring prevents signal reflections, ground loops, and hardware failure. 1. Power Supply and RS485 Communication Terminals

is a 7-channel RS485 Modbus RTU interface board designed for NTC Thermistors

“Node 01, identify yourself and report your registers,” the master demanded.

: The number of channels is fixed at seven.

Press the button once quickly. The digital display will begin flashing.

Connect the TXD of the NT18B07 to the RXD of your microcontroller (e.g., Arduino, STM32) and the RXD of the NT18B07 to the TXD of the microcontroller. Ensure a common ground (GND) is used. 4.2. Initial Testing Power the module using 5VDC. Connect the module to a PC using a USB-to-TTL converter. Open a terminal emulator (e.g., PuTTY) set to 19200 baud. Present a 125KHz card.

Always remove the 18V Li-ion battery before clearing a jam or performing maintenance. Eye Protection: Wear ANSI Z87.1-rated safety glasses.

The thermistors use standard . Because NTC thermistors are non-polarized resistive components, the orientation of the two wires plugged into any given channel (CH1 through CH7) does not matter. Connect one lead to the signal terminal and the other to the adjacent local ground on the terminal port. Modbus RTU Protocol and Register Mapping

The NT18B07 responds exclusively to standard Modbus RTU frame queries. Data packets are verified sequentially via a standard algorithm to ensure error-free transmission. Register Address Mapping
