Tips: The difference between RS232 and RS485 Converter.
The difference of the communication line of the interface:
RS232 generally uses three-core twisted pair, three-core shielded wire, etc.
RS485 uses two-core twisted pair, two-core shielded wire, etc. Ordinary twisted-pair cables can be used in low-speed, short-distance, and interference-free situations. On the contrary, in high-speed and long-term transmission, RS485 dedicated cables with impedance matching (usually 120Ω) must be used. Should use armored twisted-pair shielded cable.
Generally speaking, RS232 has not many advantages, and the transmission distance is only 15 meters, but it is very useful. For example, it may be used in monitoring, upgrades and debugging of other equipment, and the function is more hand-over with USB, so there is now a USB conversion port. , Not only to obtain a higher transmission speed, but also to solve the shortcomings that the USB interface cannot be transmitted over long distances.
