Question

Serial port

Hello! there is a server with serial port rg-45, how to connect it to a computer without a com port?

Answer 1

To get started, find out the pinout and type of signals: COM 12v or TTL 3.3v - if 12v then you need a converter chip MAX232. In the basic version, 2 Rx, Tx signals and a common GND wire are sufficient. The rest are rarely required - usually it is said in the documentation.
