What is RS485 communication converter
RS485 communication converter also called RS485/232 converter is a device to convert the RS485 communication bus to the RS232 computer serial port. It effectively solve the following disadvantages of RS232 serial communication:
1. RS232 communication short distance 20 meters in theory.
2. RS232 communication point to point communication.
After using the RS485 communication converter can be achieved:
1. The theoretical distance betweens the computer to the last RS485 equipment is 1200 meters (hand in hand). 2. The computer can communicate to any equipment on the 485 bus through RS485 communication converter. That is means access control can work in network.
