Product characteristics
This transparent transmission module realizes the mutual conversion of TTL signal and RS485 signal, but 485 is half duplex communication. This communication mode can buy two-way communication, but it can not be carried out in two directions at the same time. It must be carried out alternately in turn. That is to say, each end of the communication channel can be the sending end or the receiving end, but at the same time, the information can only have one transmission direction.
This module realizes the mutual conversion of TTL signal and RS485 signal, without "receive send" control. Using this module is as simple as your serial port operation, and it is compatible with 3.3V and 5.0V power supply, 3.3V and 5.0V signal. The original imported chip is adopted, which has very stable performance and meets the industrial design standard. It has strong anti-interference ability and more effective 485 lightning protection design, which can be used in the industrial field and field Under the environment, the transmission distance can be up to km (for the test with 850m 2 * 1.5 cable, it is recommended to use it within 800m, please add a repeater if it exceeds 800m).
