Data transfer and control of annunciation
The reader is provided with two-colour LED indicators and buzzer. LED and buzzer function
according to interface type programmed and annunciation mode.
Wiegand Interface
Engaging of LED and buzzer is possible automatically or by grounding of corresponding
wire according to Table 2.
Keypad codes
Reader transmits keypad codes in one of the programmed modes
– package or digit-by-
digit.
In package mode reader stores up to 10 presses of ‘0’ to ‘9’ keys and transmits package
after the ‘#’ key press. If there are less than 10 digits pressed the leading digits filled with
hexadecimal digit ‘F’. The ‘*’ key press clears all previous key presses.
In digit-by-digit operation mode reader transmits the key code immediately after the key
press with 6-bit package. The key codes are in the table below:
