USB-485 program on the market for analysis

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

PL2303 + RS232 + RS485; This program is to use PL2303 first into a serial port, then the serial port into 485; advantage of low cost, shortcomings may exist in industrial instability, high speed is not suitable.

Advantages: industrial applications, speed, anti-interference ability is very good, very suitable for industrial areas, personal applications. Disadvantages: high cost.
