XRCa RFID reader writer can work in two basic modes : autonomous and non-autonomous.
In non-autonomous mode device acts as all other readers from µFR series, like Classic, Nano, Advanced. Same protocol, libraries, SDK API and examples are used for this purpose. Significant difference is that µFR XR/XRc devices can work on installations where long cable runs are must. So, for example, you can establish PC-µFR XRc communication link with 1000 ft cable using only USB power.
In addition, µFR XRc device has a built-in access control IO module, which has the following functionalities:
Door strike lock contacts
Push to open button contacts
NO & NC relay contacts
Door state contact inputs
When used in autonomous mode, device can act independently, without the connection to the host. Only USB or other type of power supply is needed (5V DC). Device stores card related events in non-volatile memory. Each event is also sent asynchronously to host as a Real-Time Event (RTE). Device can store up to 16384 separate events. After it’s buffer is overflowed, it starts to erase the oldest events in order to free memory for new forthcoming events.
