CHAPTER 1 Cubic Tri-Reader 2
1.1 Introduction
The Cubic Transportation Systems, Inc. (Cubic) Tri-Reader® 2 will serve as a front
end for a remote ticketing device used for automatic fare collection (AFC) in public
transportation systems (e.g., bus, rail, subway, etc.). It can be used in ticket
validators, ticket vending machines, gates, and other AFC equipment. This
equipment can be onboard vehicles or in fixed ground locations. The Tri-Reader 2
will be responsible for direct communication with a Contactless Smart Card (CSC),
which is a type of radio frequency (RF) tag. The design caters for at least three
types of CSC, namely Type A, Type B, and GO CARD®.
Interpretation of the information stored on the CSC, as well as the processing of the
revenue collection transaction, will be done by the Tri-Reader 2 itself, based on
faretables and hot-lists provided by the host computer.
The firmware on the Tri-Reader 2 is designed to be updated in-system using
FLASH-based technology. It will therefore be possible to cater, within limits, for
different CSC types and configurations — if so required for the future.
In broad terms, the communication task will therefore proceed as follows:
1. The Tri-Reader 2 will power the CSC through radiation by an induced RF
field.
2. By sequencing through the communication protocols for the different
cards, it will detect the card type by checking for the associated
response.
3. Once the card type and therefore its communication mechanism is
known, the Tri-Reader 2 will read and write data on the card according to
the fare rules in the faretables.
4. The Tri-Reader 2 will pass data to and from the CSC by using the
appropriate protocol for modulation and demodulation of the signal.

1.2 Tri-Reader 2 Antenna Type
The Tri-Reader 2 is a loop antenna with a diameter of 78 mm.
Figure 1. Tri-Reader 2 Antenna
1.3 Tri-Reader 2 Interface to Host Unit
There will be a one-to-one (RS422) link between the Tri-Reader 2 and the Host unit.
The Tri-Reader 2 will operate as a single Remote Ticketing Device (RTD).
A shielded RJ45 connector connects the Tri-Reader 2 to the Host unit. This link is
for the serial data.
1.4 RF Communication
All RF communication between the Tri-Reader 2 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 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.

1.4.1 RF Field Strength
The magnetic field strength is approximately 8 A/m in the center of the antenna and
falls off by the third power of the distance. The electric field strength is determined
by the voltage applied to the coil as well as the efficiency of the antenna as a
radiator. The effective applied voltage is approximately 6 Vrms, but the antenna is
fitted with a balanced shield, reducing the apparent common mode voltage to 0.
1.4.2 Modulation Types
The signals for communication between the Tri-Reader 2 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 kbit/s. Card-
to-reader, ASK - Manchester, load modulation - subcarrier
fc/16, 847.5 kHz, 106 kbit/s.
CSC Type B: Reader-to-card, ASK 10% modulation index NRZ, 106 kbit/s.
Card-to-reader, BPSK-NRZ load modulation subcarrier fc/16,
847.5 kHz, 106 kbit/s.
Type GO CARD: Reader-to-card, ASK 8% modulation index NRZ, 115.2 kbit/s.
Card-to-reader, ASK-NRZ load modulation, 115.2 kbit/s.
1.5 Tri-Reader 2 Printed Circuit Board Size
The Tri-Reader 2 consists of an 86.5 mm diameter circular digital board and an 83
mm diameter antenna board. Thickness, including components and antenna board,
is 17 mm, except for the RJ45 connector which extends 10 mm above the
components on the back of the board, giving a maximum thickness of 27 mm.

1.6 Tri-Reader 2 Physical Interfaces
The following physical interfaces apply to the Tri-Reader 2:
1. The Tri-Reader 2 is powered from 5 to 28 Vdc. It can draw a maximum
current of 1.5A (at startup) and dissipates up to 2 Watts. This can be
supplied either via an expansion connector (J8) or it can be tapped from
the host communication cable, in which case it will come in on the RJ45
serial comms connector (see the pinouts below).
2. The Tri-Reader 2 comms can be set to be either RS232 or RS422/485
levels. RS232 mode is selected by software.
3. The Tri-Reader 2 automatic baud rate detection between 9,600 bps and
921,600 bps.
4. If RS232 is used, only two of the four comms lines on the RJ45 connector
are required. Pin 2 on the RJ45 connector is the Tri-Reader 2 receive line
(232Rx) and should be connected to the host computer Tx output (pin 3
on a normal DB9). Pin 6 on the RJ45 connector is the Tri-Reader 2
transmit (232Tx) line and should be connected to the host computer Rx
input (pin 2 on a normal DB9).
5. If RS422 or RS485 is used, 485RxL must be taken to the host transmit
low, 485RxH must be taken to the host transmit high, 485TxL must be
taken to the host receive low, and 485TxH must be taken to the host
receive high.
6. The Tri-Reader 2 has an onboard tri-color LED indicator.
7. The RJ45 communications connector is a shielded type that is mounted
in the J5 position. It mates to any standard RJ45 cable connector. Table 1
provides the J5 pinouts.
