CDVI STAR1M Manuel D'installation page 15

INSTALLATION MANUAL
STAR1M - Standalone Access control system / 13,56 MHz Mifare
- Programming mode is exited after 10 seconds without any actions
- The white and red LED flash the number of times that correspond to
the configured number of seconds, followed by a BEEP
- Exit from programming mode: BEEP and return to the blue LED.
Deleting all cards (return to the default configuration)
- Cut the STAR1M power supply / Position DIP1 to ON
- Turn the STAR1M power supply back on. (Switch to Mifare
- The white/red LED is activated while the memory is deleted.
- The deletion of the memory is followed by the start-up sequence
(green, red, blue + BEEP)
- Wait for the start sequence to end and then cut the STARM1
power supply.
- Position DIP1 and DIP2 to OFF (switch to standalone system mode)
- The device waits for a new Master card to be placed in front of the reader
- Turn the power supply back on, the STARM1 is ready for reprogramming.

9.1 WIEGAND 26, 30 and 44 bit output format
26-bit Wiegand Output
Hexadecimal 26 bit format. Communication uses a Wiegand 26 bit type signal
(signals: DATA1, DATA0). The frame is composed of a total of 26 bits split up as
follows:
1. First parity: 1 bit - parity for the first 12 bits.
Badge code: 3 one byte words representing the 6 last terms
Each word is sent with the most significant bit first.
2. Second parity: 1 bit - odd parity for the last 12 bits
Bit 1
Even parity on bit 2 to bit 13
For example: for a card with hexadecimal code 00166A37
1 0001
Parity 1 1
The transmitted hexadecimal code is 166A37
Parity 1: 0 if the number of '1's in bits 2 to 13 is even,
1 if the number of '1's from bit 2 to 13 is odd.
Parity 2:
0 if the number of '1's in bits 14 to 25 is odd,
1 if the number of '1's from bit 14 to 25 is even.
Bit 2 à bit 25
