This module enables bidirectional wireless data transmission via LoRa. It can transmit data to a 485, 232, or TTL interface for transparent transmission. The maximum wireless transmission distance is 6000 meters (maximum power, minimum data rate, unobstructed). The maximum communication distance via the 485 interface is 1000 meters, allowing direct connection to PLCs, industrial control instruments, configuration panels, or configuration software in the field. It can be widely used in industrial sites and other locations where cable routing is inconvenient, significantly reducing operating costs.
Features
Utilizing LoRa transmission, device address, baud rate, transmit power, channel, and transmission rate can be set via host computer software. It can be connected to a 485 bus. Designed and manufactured according to industrial standards, the product features overvoltage protection, overcurrent protection, strong anti-interference capabilities, and high reliability.

Product Usage
1. Upon receiving the product, confirm the baud rate of the 485/232/TT1 connected devices. The default baud rate for this product's 485/232/TT ports is 9600N81. If the baud rate of the connected devices matches this, it can be used immediately upon power-on without any changes. If they are different, the baud rate parameter can be modified through the configuration software.
2. For communication between two networks, the ID and channel need to be set separately. Devices with the same ID and channel can communicate, while those with different IDs cannot.
Example: Device A communicates with device B, and device C communicates with device D. To prevent communication between pairs A and B, and C and D, set the ID of A and B to 1 and the channel to 0, and the ID of C and D to 2 and the channel to 1. Leave other parameters unchanged.
