The data-clock interface is only available in Scan-Mode.
The data-clock interface cannot be used to configure the reader.
The digital outputs OUT1 and OUT2 are not available, if the data-clock interface is activated.
The data as well as the clock need to be supplied with an external voltage. The output is
configured for max. 24 V DC / 30 mA.
Figure 12: Wiring Example
NOTE:
Please consider possible limitations of the Wiegand Controller regarding the used supply
voltage.
In dependency on the inner circuit of the used Wiegand Controller it is necessary to use
external serial resistors to limit the current on the data and clock wires.
The necessity of the external pull down resistor is depending on the inner circuit of the
used Wiegand Controller
