6.1 The ILR-Card
The ILR-CARD is the rear PC Card on the left side. It has two I/O
connectors on the exposed end, the MMCX Antenna connector, and a
15-pin programming connector. The programming connector is used by
IDENTEC to configure the ILR-CARD. There are also three LEDs on
the exposed end of the ILR-CARD to indicate transmit, receive and RF
carrier detect.
The ILR-CARD contains a Configurable Processor System Unit
(CPSU) with internal non-volatile memory. The CPSU chip is
programmed by IDENTEC and contains the firmware code to run the i-
PORT. The CPSU also contains a Real Time Clock, with a separate
power supply that will power the clock for over 24 hours.
The ILR-CARD contains the RF circuitry for the wireless
communication with IDENTEC tags. The application software running
on the i-PORT, or other host computer, sends commands to the CPSU
to communicate with the tags. The CPSU on the ILR-CARD controls
the function of all LED’s on the LED Board, as well as the Piezo buzzer
on the Power Supply Board. It also manages the 6V backup battery
charge function. The normal mode (power-up and standby) of the ILR-
CARD is ‘Receive Mode’, as opposed to the time-limited ‘Transmit
Mode’, which has to be initiated by the controlling host computer.
Note: The ILR-CARD used in the i-PORT is in a PC Card Type II
housing but it is not configured with a PCMCIA interface. The ILR-
CARD in the i-PORT has a serial interface and can only be used in the
assigned card slot on the i-PORT. Each ILR-CARD is marked with an
