8. Portal Functional Description
The ProxTrak Portal Reader integrates the Access control and Asset control functions in the same Reader,
styled in a fashion resembling a styled metal detector at the airport. The combination of Access and Asset
controls, with the ability to track presence of individuals, creates a powerful Reader that can be used to
expand the capability of the traditional Access control system to include Asset tracking and management.
The doorway sized unit enables the integrator to pursue hands-free Asset control, increasing throughput,
reducing paperwork, and bring asset management to a new level of traceability and ease of use.

Product, integrated as a
presentation style reader so that tailgating and other activity around the Portal can be closely monitored.
8.1 Operating Cycle
Upon power up and during operation, the Reader performs various self-diagnostic and optimization
operations. Messages from this process are sent to the host (if requested). See the Protocol Spec for
more information.
After initialization, the Reader responds to polls from the host by starting a scanning cycle, or in free-
running mode, periodically steps through the scanning sequence by searching for Access or Asset tag
data. Before starting the scanning sequence the Reader detects interfering 125kHz equipment. In a mode
called Maui (Multiple Adjacent Unit Interface), if a 125KHz source above a threshold power is detected, the
Reader waits for a quasi-random interval before another attempt. This process allows the Reader to get in
sync with another Reader that is close enough to be detected, and get successful acquisitions when
traditional Reader technologies would not.
If an Asset or Access tag is detected, its identification is transmitted to the host as described in the
Protocol Specification. The Reader acquires the information regarding Asset and Access tags and the
entrance and exit sensors, and passes them along to the host.
The decisions regarding interpretation of the data and the resulting actions, are implemented by the system
integrator.

8.2 RFID Tag and card types
8.2.1 Asset tags
The ProxTrak Portal Reader will perform transactions with any Asset ID
The ProxTrak Portal Reader will perform transactions with any Asset ID
compatible Asset tag including
the HID AMT100 Asset Management Tag and Asset ID
source tags in IBM
computers. Read area is
within the full volume of the Portal. The Reader outputs a 12 byte ID string imbedded in the "TAG ID
message". Asset ID
message". Asset ID
is a registered trademark of IBM PC Company.
8.2.1.1 Asset tag types
The system is designed to read up to 5 Asset tags within its range. The Multi-Tag technology has been
developed by Atmel Corp and as a result, there are 8 tag types available. Any tag that is programmed will
be one of the eight tag types. If up to 5 different tag types are in the range of the reader, they will be read
successfully. If tags that are the same tag type are present in the field, the Atmel design results in timing
collisions, and the read performance is reduced.
