2 TR4 Components
2.1 TR4 Antenna Type
The TR4 has a loop antenna with a diameter of 78 mm (shown in Figure 1).

2.2 TR4 Interface to Host Unit
A shielded RJ45 connector connects the TR4 to the host unit using a 10/100 Base-T Ethernet link.
This is a data link and may be encrypted with P2PE (Point-to-Point encryption).
The TR4 will operate as a single Remote Ticketing Device (RTD).
2.3 RF Communication
All RF communication between the TR4 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.
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.
2.3.1 Modulation Types
The signals for communication between the TR4 and the CSC will differ between card types. In some cases,
data will be modulated onto a carrier only, while in others a subcarrier will also be present. The modulation
schemes used for communication also differ from one card type to another as described below:
CSC Type A:
Reader-to-card, ASK 100% modified miller, 106 kb, 212 kb and 424 kb.
Card-to-reader, ASK - Manchester, load modulation—subcarrier fc/16,
847.5 kHz, 106 kb, 212 kb and 424 kb.
CSC Type B:
Reader-to-card, ASK 10% modulation index NRZ, 106 kb. Card-to-reader,
BPSK-NRZ load modulation subcarrier fc/16, 847.5 kHz, 106 kb.
