On the market to USB switch 485 program analysis

 

Option 1: CH341 +485; shortcomings of instability, easily lead to computer black screen;

Option 2: PL2303 + RS232 + RS485; This program is the use of PL2303 first turn into a serial port, then the serial port into 485; the advantage is low cost, shortcomings of industrial occasions may be unstable, high speed is not suitable.

Option 3: FT232 + 485; Advantages: industrial applications, the speed of anti-interference ability are very good, very suitable for industrial areas, personal applications. Disadvantages: high cost
