UM0001-1B.00 June 17, 2002 User Manual for the CTS Tri-Reader 1-1 CHAPTER 1 CTS Tri-ReaderTM 1.1 Introduction The Cubic Transportation Systems, Inc. (CTS) Tri-Reader 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 will be responsible for direct communication with a Contactless Smart Card (CSC), which is a type of radio frequency (RF) tag. The naming refers to the fact that 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 not be done by the Tri-Reader itself, but rather by the central processing unit (CPU) to which it is a slave. Unsolicited messages will only be passed from the Tri-Reader to the CPU when the unit is told to search for and report any CSCs found to be present. Beyond establishing the card's presence and performing collision detection, the Tri-Reader will be a “dumb” data link between the CPU and the card. The firmware on the Tri-Reader 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 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 will communicate the card type to the CPU. 4. The Tri-Reader will pass data to and from the CSC by using the appropriate protocol for modulation and demodulation of the signal.
June 17, 2002 UM0001-1B.00 1-2 User Manual for the CTS Tri-Reader 1.2 Tri-Reader Antenna Type The Tri-Reader is a loop antenna with a diameter of 75 mm. 1.3 Tri-Reader Interface to Central Processing Unit There will be a one-to-one (RS422) link between the Tri-Reader and the CPU. They will operate as a single Remote Ticketing Device. A shielded RJ45 connector connects the Tri-Reader to the CPU. This link is for the serial data. 1.4 RF Communication All RF communication between the Tri-Reader 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 will be self-tunable via software resident in the local control processor. The modulation/demodulation scheme will also be automatically selected by the local controller. 1.4.1 RF Field Strength The magnetic field strength is 10 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 6 Vrms. 1.4.2 Modulation Types The signals for communication between the Tri-Reader 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.

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 Printed Circuit Board Size The Tri-Reader is a 86.5 CPU x 86.5 CPU circular board. Thickness, including components and antenna, is 18 mm, except for the RJ45 connector which extends 10 mm above the components on the back of the board, giving a maximum thickness of 28 mm. 1.6 Tri-Reader Physical Interfaces The following physical interfaces apply to the Tri-Reader: 1. The Tri-Reader is powered from 8 to 28 Vdc. It can draw a maximum current of 1.5A (at startup) and dissipates up to 5 Watts. This can be supplied either via an external power connector (J11) or it can be tapped from the CPU, in which case it will come in on the RJ45 serial comms connector (see the pinouts below). 2. The Tri-Reader comms can be set to be either RS232 or RS422/485 levels. RS232 mode is selected by soldering a 0 ohm resistor into the R35 location. Leaving R35 unpopulated selects RS422/485. 3. The 3-bit multi-drop unit ID (Unit_ID) of a Tri-Reader needs to be set if more than one Tri-Reader is to be multi-dropped to a single host computer. If it is unconnected, the unit ID defaults to 001b. Multi-dropping is only possible if RS485 is used. There are pull-up resistors on the Unit_ID lines, so only zeroes have to be driven/tied to a CMOS logic low level. 4. If the user desires to operate the Tri-Reader interface at 115,200 bps, the Unit_ID currently has to be set to 000b. Otherwise, the baud rate will be fixed at 921,600 bps.
June 17, 2002 UM0001-1B.00 1-4 User Manual for the CTS Tri-Reader 5. 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 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 transmit (232Tx) line and should be connected to the host computer Rx input (pin 2 on a normal DB9). 6. If RS422 or RS485 is used, a one-to-one RJ45 cable to the CPU board can be used. Otherwise, 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. 7. The Tri-Reader has an onboard tri-color LED indicator, so the external buzzer and LED outputs are optional. The two external LED outputs are buffered copies of the lines that drive the onboard LED and can drive 100 mA and withstand 60V, so they can be used to drive relays if required. 8. The buzzer line is an unbuffered 5V CMOS level port pin of the onboard Micro. Both buzzer and LED operation is controlled by commands from the CPU board. 9. Resulting states for the external LED lines are listed in Table 1. Table 1. External LED Line Resulting States EXT_LED0 EXT_LED1 LED Color LO LO Off LO HI Red HI LO Green HI HI Yellow
