1 5 volts power supply (from Adaptor to Wall Reader)
2 PPD connection (not used)
3 Ground
4 Data input-output
5 Card Present
3.2 External Device Connection
The interface with the external device can be RS232, OMRON and WIEGAND. The connection is made
through a 4 pins block terminal.
The functions of the 4 pins connector are different depending on the selected type of interface:
Interface Connector Rx/D0 Tx/D1 GND +V
RS232 RX TX GND +V
OMRON CLOCK DATA GND +V
WIEGAND D0 D1 GND +V
The Wall Reader Adaptor is powered from the external device through pins +V and GND. Optionally can
be powered through the jack connector.
The Wall Reader Adaptor is continuously looking for a card and when one is presented it sends the data
to the external device giving simultaneously a valid signal (green led and beep).

Desktop Reader and Wall Reader Adaptor needs a DC power supply with a voltage between 7 and 15
volt.
The typical current consumption is 15 mA (maximum 30 mA) plus the current consumption of the reader
that depends on the technology:
