*The specified read range assumes no electrical interference and that the card is presented
parallel to the reader, with the reader installed and operated as outlined in this manual. The
read range will vary depending on the type of card used. The larger the card, the greater the
read range. The read range may decrease if the reader is mounted on metal.
Basic Operation
When power is supplied to the reader, the antenna in the reader will emit a
continuous low-frequency RF field. When a card is placed within this field, the
antenna inside the card will gather the energy present in the field to power the
internal circuitry of the card. The card will then transmit its unique identification (ID)
number to the reader. After receiving the signal, the reader verifies the validity of
the signal. If the signal is valid, it will be decoded by the reader and sent in the
appropriate output format to the host controller through data cables. The controller
then determines what action to take in response to the information received from
the reader. See Figure 1 on page 25.
Power Requirements
The controller's power supply may not be able to supply sufficient power to the
PosiXtend extended range proximity reader, therefore an external power supply
unit, such as the Paradox Switching Power Supply (PS-817) is needed. Refer to
Figure 4 on page 27 or Figure 7 on page 30 for power supply unit connections.
Dimensions
Please see Figure 3 on page 26 for PosiXtend's dimensions.
