| Abstract: | In this paper, the COM port for RS-485 is used in the long distance communication by contrasting the COM ports for RS-232 and RS -485. Furthermore, the long distance communication port circuit and its disposal method for both Microchip and Personal computer are developed as MAX485 chip is an example. The work principle of COM port communication for RS-485 on the Microchip and Personal computer is simply discussed, and the sketch map and program to carry out the communication for the Microchip and Personal computer are presented. |
| Keywords: | COM port RS-232 RS-485 The TTL electricity is even Resonant mode Differential mode Bits frequency |
