The NT18B07 utilizes a structured communication protocol to interact with a host microcontroller or PC. Commands are sent in specific data packages to configure the reader or request data. 3.1. Data Packet Format
Supports up to 247 modules on a single RS485 bus via hardware address modification (RS485 repeaters are required if cascading more than 16 modules). Physical Dimensions: 60 mm × 37 mm × 14 mm. Weight: 19 grams. Pinout and Hardware Wiring Guide
The is a 7-channel RS485 temperature measurement module. It uses the Modbus RTU protocol to communicate with computers or PLCs, allowing you to connect up to seven NTC thermistors (specifically the B3950 10K 1% type) to monitor temperatures across multiple points. nt18b07 manual

The NT18B07 module utilizes straightforward terminal blocks. Maintain clean wiring to prevent data packet drops or ground loop issues. Polarity does not matter for the NTC thermistors themselves
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 avoid address conflicts when using multiple modules on the same bus, the address of each unit can be changed via Modbus. To change the address from its default of 1:
