In this section, you can configure the following parameters:
available identifier formats for the reader to work with:
ASK: enabling signal transmission in amplitude-shift keying that is used in EM-Marin Classic cards and keychains;
Expand title More about ASK ... With amplitude-shift keying, each digital symbol is associated with its own carrier signal amplitude. The frequency and phase of the keyed signal remain unchanged. Amplitude-shift keying is rarely used in practice, as it is the least antijamming. And it is usually used in combination with other keyings.
The figure below shows a graph of a binary sequence of 0 and 1 and, corresponding to it, a graph of an amplitude-shift keyed signal. A low level encoding of a binary signal uses an amplitude of 0.5 V, and a high level uses a 1 V amplitude of a sinusoidal carrier signal.
FSK: enabling signal transmission in frequency-shift keying that is commonly used in Temic cards and paired with ASK keying;
Expand title More about FSK ... With frequency-shift keying, each digital symbol is associated with its own carrier signal frequency. The amplitude and phase of the keyed signal remain unchanged. The figure below shows a graph of a binary sequence of 0 and 1 and, corresponding to it, a graph of an frequency-shift keyed signal. The low level corresponds to a frequency of 1 kHz, and the high level corresponds to a frequency of 0.5 kHz of a sinusoidal carrier signal.
Mifare: enabling signal transmission for working with Mifare cards;
Bluetooth: enabling signal transmission for working with Bluetooth identifiers (UKEY);
Inner Range: enabling the operation with specialized IR cards.
type of output interface for data transfer to the panel: Wiegand Automatic, Wiegand-26, 32, 34, 37, 40, 42, 56, 58, 64. Selected Wiegand type must coincide with the indicated in the panel settings one;
encryption password for UKEY identifiers;
Mifare profiles (depending on Mifare cards types that are used).
Expand title More about Mifare technology ... Mifare technology is usually used in complex systems where privacy and data protection are very important. To ensure protection and security, the technology processes data using keys and cryptographic algorithms. The readers to work with Mifare identifiers must also maintain data protection and security on their part. So, the reader must also store in its memory the access keys for each sector of the Mifare Classic.
Mifare Plus contactless smart cards are designed to increase the existing level of security. Mifare Plus provides full bottom-up compatibility with Mifare Classic 1K and Mifare Classic 4K products. Mifare Plus cards can easily be integrated into existing systems where Mifare Classic cards are already in use. The security level of Mifare Plus cards can be increased at any time as the system develops by activating the AES (Advanced Encryption Standard) algorithm, which provides a high level of security, data integrity, authentication, and encryption.
For all available profiles (Mifare Classic, Mifare Plus, Mifare profile 3, Mifare profile 4, Mifare profile 5) you can set the following parameters:
security: card encryption enabling/disabling;
...
| Info |
|---|
Available security levels (depending on profile type):
|
key (available if the cards are encrypted): the encryption key for Mifare identifiers (12 hexadecimal characters);
read sectors (available if the cards are encrypted): sector values that are obligatory to be read;
read (available if the cards are encrypted): conditions for card reading;
...

Available options:
|
use address (available if the cards are encrypted and the read by address is selected): a bid-endian or little-endian way of reading;
card code byte order.

Mifare Plus chips (in cards, keychains, bracelets, etc.) are at the SL0 security level by default. It is impossible to use cards at the SL0 level in the application system, the Mifare Plus chip must be upgraded to SL1, SL2, or SL3. When initializing the Mifare Plus chip, the object owner must generate the key values and store this information securely.
