RS485 Communication module C1A-L1GI

Product Introduction
The module converts TTL signals into standard RS485 MODBUS-RTU signals and provides the module station address through a dial switch. Convenient for the use, maintenance, and replacement of multiple parallel products. No software modification is required, just corresponding to the original dial switch. Suitable for parallel use of multiple modules.
Set the RS485 address of the smart bus device.
Set the device address of the smart bus through the dial switch on the board. There are a total of 16 address dialing bits, and the device address is set in binary encoding. From left to right, it is the highest bit to the lowest bit, with 1 bit set to ON and the rest set to OFF, that is, the module address is 1. Set 8 bits to ON and the rest set to OFF, that is, the module address is 8.
