RS485 network door access control system
RS485 door access control system is based on RS485 communication which uses bus connection (handshaking mode). The maximum transmission distance in RS485 system is 1,200 meters (3,888 feet) or longer with RS485 expander. Because of the built-in RS485 communication chip and handshaking bus wires connection, the system will remain same communication if any node is defective.
In RS485 door access control system, the shield twisted 2 core wire is recommended, being shield and being twisted is for reducing the noise generated by magnetic fields from the environment and maintain the stability of the communication.
The transmission and reaction speed of RS485 door access control system would be declined gradually when the transimission distance expanding due to the the spedcial characters of RS485 communication( the control center ask and each node answer one after another, the rest nodes must be waiting for their turn if an answering signal is transimissed over the bus wires).
RS485 door access control system is still the most popular used door entry control sytem because of its easy installation and cheap cost. When the system installs access control main boards under 100, the system could run smoothly without any problem, but when the amount exceed 100, you will be recommended to be careful to consider the stability before your purchasing.
One thing to remind, in theory the distance for RS485 is 1200 meters, but it is recommended that the best performance is under 800 meters because the longer distance the less stable the data transimission is.
