T20128 and T20678 Gateway Boards
T20128-GX Gateway Board is used in the Full System T20229-G1 and T20606-G2 Card
Cages. The T20678 Gateway Board is used in the T20606-G3 Card Cage. These boards
manage events and message processing to/from the Controller (CRIND, POS, host controller)
and the readers. On the full systems, the Gateway Board manages RFID processing through
the DCB (which communicates with the vehicle tags via overhead antennas and with
hand-held tags via bezel readers). On Enhanced Gateway systems, the board manages
hand-held RFID processing through direct communication with the bezel readers.
