Explanation of communication wiring: Extend the 485 lines (A and B) of the belt controller to two ways (A2, B2) and (A3, B3).

DAQ-GP-485HUB is an RS485 bus multiplexing shared data processor launched by Shanghai Digital Internet of Things, which is a high-performance communication device specially designed for the data conflict caused by the communication between two hosts and one slave. In real industrial control and monitoring scenarios, multiple hosts sending requests at the same time can lead to data conflicts, affecting system stability and reliability. The processor achieves high-speed and stable communication by connecting two hosts and one slave to a single RS485 interface. The processor supports a variety of protocols, baud rate adjustable, to adapt to a variety of different scenarios of communication needs. Moreover, the processor also has excellent rail mounting, small and compact features, easy to install and use in limited space. In short, this multiplexed RS485 hub is a high-performance, outstanding reliability of industrial equipment, can be stable and efficient solution to the two hosts and a slave communication caused by data conflicts, improve the stability and efficiency of the entire system, is a very worth recommending and using the product.
