The manual describes the ZigBee1082 wireless data acquisition card from Aertai Technology, including terminal wiring, DIP switch settings, LED indicators, and a temperature sensor for thermocouple cold-junction compensation. It lists supported thermocouple input types and key electrical specifications.
The document also provides MODBUS protocol address maps and command examples for reading holding registers, reading input registers, setting a single holding register, and setting multiple holding registers. Version 6.010 is shown on the manual pages. This manual is written in Chinese.

Short the INIT pin to GND before powering the module, then power it on. The module restores the default address 1 and baud rate 9600.
The green LED is the power indicator, the yellow LED is the network indicator, and the red LED is the communication indicator.
It uses an unprocessed +10 V to +30 VDC power supply.
Set SW1 positions 1 and 3 to ON and 2 and 4 to OFF, connect the module's RS232 port to a computer, and use DIGI X-CTU software.
