How to connect the computer through the communication converter to break the access control system? I read the TV on what agents with the access control system and the computer together and then crack, that is the communication converter? As if what software, can specifically say it?
RS485 communication: the computer through the communication converter access access RS485 bus, open the software, will register a good card or fingerprint upload to the host, OK! You can go open the door. But must be in the original computer off the case, because the RS485 communication protocol does not allow the presence of two PC at the same time.
Effective and feasible to crack the basic work: First, to know the specific model of access control and a set of background software, this is the first question;
2, there are two kinds of network access control: one is based on RS485 communication, which use communication converter, one is based on TCP / IP communication, no communication converters, as long as the use of network port (RJ45) on the line. Here are two kinds of analysis:
??1, independent access control system is an identity judging system and drive the electric lock system package together, so, as long as the open separate access control shell (because you want to punch or fingerprint, so are installed outside the door), carefully observe the terminal, Find "out button" (or BUTTEN, English note not clear) terminal, short circuit on OK! Haha.
Access control system big title in two ways: one is an independent access control, the other is a network access control, the following probably talk about how to crack:
