2. Readers are connected to the controller by 22AWG or 24AWG cable (e.g. 8x0.5 vinyl-
sheath cable for transmission systems). "Twisted pair" cable is not recommended for
making connection.
3. Do not place reader in areas with sources of wide spectrum electromagnetic noise,
e.g. motors, generators, DC/AC converters, uninterruptible power supplies, AC relays,
lighting controls, monitors, etc.
4. Place the cable of the reader at a distance of not less than 0.5 m from other cables,
including AC power cables, computer cables, telephone cables or electromechanical
lock power cords.
5. To eliminate the mutual influence, the distance between two readers of standard read
range (up to 15 cm) should be at least 0.5 m. This distance is proportionally increased
for readers with enhanced range and is reduced for readers with shorter range.
6. The maximum current consumption of each reader must not exceed 200mA, the
built-in controller protection will be activated in case of excessive current and it will
switch off this reader power supply. When connecting readers that consume current
of more than 200mA, a positive side
directly to the power supply terminals.
Important notes on reader use
1. Many readers support multiple output interface standards. To switch the reader to
Wiegand mode, you should refer to the respective documentation. As a rule,
switching is made by closing reader lines between each other or by means of a dip-
toggle on the reader board.
2. When using readers with standard Wiegand interface, it is possible to make a parallel
connection of several readers to a single controller output. This method can be used
for enhanced access control, when, e.g., two readers biometric and keypad-
equipped are connected at the Entrance side. However, the efficiency of this
method depends on the reader circuit design and is not guaranteed in general.
Cable color layout
When connecting readers by a 6x0.5 vinyl-sheath cable for transmission systems, it is
recommended to follow the table below:
Wiegand data «0» (or
emulation of Dallas Touch
memory interface)
DATA 0 (when connecting Touch memory
readers combined by a jumper with LED 2,
wherein the LED 2 indication control turns off).
