2.2 TRI-READER 3 INTERFACE TO HOST UNIT
There will be a one-to-one (RS-422/RS-232) link between the Tri-Reader 3 and the host unit. The Tri-Reader
3 will operate as a single Remote Ticketing Device (RTD). A shielded RJ45 connector connects the Tri-
Reader 3 to the host unit. This link is for the serial data.
2.3 RF COMMUNICATION
All RF communication between the Tri-Reader 3 and the CSC will be accomplished at a carrier frequency of
13.56 MHz according to modulation/demodulation schemes for ISO 14443 Type A, ISO 14443 Type B, and/or
GO CARD requirements. At a minimum, the RF field will be able to power up to three CSCs in close
proximity. The transmitter antenna is tuned to its resonance during production. The modulation/demodulation
scheme will also be automatically selected by the local controller.
