LEDs «RX» and «TX» initiate respectively reception and transmittance in serial port.
40 terminals are installed on the board: 14 of them are designed for external connections,
the rest are designed for connection to the turnstile units or are standby

1.6.2.3 Description of operation
The controller operates according to the program entered into microprocessor memory.
The turnstile mechanism and LED displays are controlled according to control commands and
status of rotor position sensors based on the logic downloaded into program. Control commands
can be transmitted via RS485 (from control panel) or logical inputs (by closing and opening of
inputs “INP1” ÷ “INP5” on “GND”).
The controller (along with the turnstile) can be in the INITIAL STATE (closed for access)
or in the following access modes:
SINGLE ACCESS IN ONE DIRECTION;
FREE ACCESS IN ONE DIRECTION;
LOCKING OF ACCESS
Other operating modes are combinations of various or similar modes in different
directions:
Single access in one direction and any mode in opposite direction;
Free access in one direction and any mode in opposite direction;
Locking of access in one direction and any mode in opposite direction;
“PANIC” function.
1.6.2.3.1 « INITIAL STATE »
The controller is in this mode, if there are no
commands “TO BE OPENED А/В" and the
turnstile's rotor is set to the point 0º, 120º or 240º.
In this mode solenoids lock rotor: Denied red LED is lit in both directions.
