It has two way independent of RS485 network function.Products can be easily embedded in the user equipment, achieve function of RS-485 network connection. The isolation RS - 485 circuits of using a piece of power isolation module, six road light coupling and 2 RS - 485 transceivers and device is only need to adopt a RS485 isolation module now .Simplify the customers on the isolation requirements of the design.
