standard
IEC-PC1286 is the portion of the Interoperable Electronic Lock (IECLOCK) standard that defines the communication protocol between an access control device (e.g. a card reader or fingerprint scanner) and a networked security system. It is intended to provide a universal standard for sending and receiving information between access control devices and the systems they interact with, allowing for enhanced security and convenience. The IEC-PC1286 protocol is based on the international communication standard RS485, which allows for data transmission over a two-wire cable at rates of up to 115.2 Kbits per second. It is designed to provide messages from the access control device to the security system, including door status, user identification, authentication, and access authorization. Additionally, the protocol supports commands from the security system back to the access control device such as unlocking or locking a door, setting an alarm, and displaying a message on a device display.
