8.3 Acquisition functions
The acquisition cycle of the ProxTrak Portal Reader begins either by the reception of a Poll (or indicator
command) from the Host or if in “Free running” mode it will cycle independently of the Host. See Switch
Settings.

Settings.
8.3.1 Asset tag Reception
Multi-tag algorithm - Up to five Asset tags can be acquired at a given moment. The acquisition of Asset
tags requires that the receiver and exciter work in conjunction to receive the Asset tag header, send the
acknowledge modulation, receive the data from a selected tag, and send the appropriate command
modulation back to the tag. Refer to the Atmel AT24RF08 description for a complete specification, state
diagram and Asset tag features.

8.3.2 Access Card Options
The portal will operate in one of two modes to read access cards, “Presentation Mode” or “Hands Free
Mode”. The modes are selected with switches, see the Switch Settings section for details.

TM
Reader. Access data is collected by time division multiplexing the Access function with the
Asset tag reading function. The data from the Access cards is put into a 6 byte field in the Tag ID
Message to be communicated to the Host via the serial port. Note the LED and beeper in the ThinLine

reader are used as programmable indicators.
8.3.2.2 Hands Free Access Card Reader
In this mode the portal will read a HID ProxCard when a person enters the portal. The card does not have
to be presented to a reader or specific location within or near the portal. This allows a user to pass
through the portal without having to pause or present his access card.

8.3.3 Exciter
8.3.3.1 125kHz exciter description
The excitation for Asset tags is generated by developing a 125kHz current in a coil, creating a magnetic
field, which energizes the Tags and cards, allowing them to return their respective ID and other stored
information to the ProxTrak Portal Reader. The ThinLine

Reader installed in the Portal is controlled by the
Portal hardware to energize and read Access control cards.
