How to Use the Reader
After the reader has been mounted, connected to an access control
system, and configured, it is ready for use.
4.1
Normal Operation
The reader’s normal operation is in CSN mode, in which it scans every
card and sends each card's serial number to the access control
system. This CSN is unique for each card. A short beep is emitted and
the LED momentarily turns green, and then returns to red.
In this mode, only MIFARE 1K and MIFARE 4K cards are
supported. MIFARE Ultralight and DESFire cards are non
functional.
If the card serial number is not fully transmitted, only the LSB
portion of the serial number is transmitted. This depends on the
reader transmit format of the selected reader and the length of
the card serial number. For example, when the Wiegand 26-bit
transmit format is selected; the MSB byte of the MIFARE 1K
card’s serial number is not transmitted.
4.2
Optical Back Tamper
The AY-Q6250 and AY-Q6350 includes an optical back tampering
mechanism which detects all attempts to dismantle the unit or
remove it from the wall.
The status of the tamper mechanism is indicated by the purple
Tamper control wire.
When the back tamper optical sensor is in “darkness” status, the
internal tamper output transistor is pulled to low.
When the back tamper optical sensor is in its "lit" status, the internal
tamper output transistor's collector is open. A tamper signal is
detected by the host control panel.
