The Reader Operation
Reading of identificator code
The code reading is annunciated by built-in buzzer and two-color LED according to
interface type and annunciation mode (refer to «Data transfer and Annunciation»).
Repeated reading will be available after 0.8 sec if the identificator is moved away from
the reader sensing area.
Hold Mode
Reader is turned to the hold mode while yellow wire is closed to the ground. In this
mode reader does not read cards, thus current consumption decreases to 25mA.
Do not apply voltage to hold outlet!
Data transfer and Annunciation
The reader is provided with two-color LED and built-in buzzer. LED and buzzer function
according to interface type programmed and annunciation mode.
Wiegand or TouchMemory Interface
Engaging of LED and buzzer is possible automatically or by closing of corresponding
wire to the black wire (GND) according to Table 2.
Table 2. Annunciation mode:

Data transmissions from reader comply with the standard specified. Protocol for
TouchMemory interface from family 01 (to satisfy the requirements DS1990).
RS232 interface
To control annunciation send three-byte control packet to the reader. Packets should
be transmitted with 2 400 bits per second, 8 bit data, no parity, 1 stop bit.

1 – corresponds to LED or buzzer switching on. LED blinking and buzzer pulsatory
control bits have the highest priority.
Annunciation does not change until next control packet is received.
