Product Overview
The ViVOpay OEM S500 Vending Reader (the Reader) is an electronic module capable of
communicating with ISO 14443 Type A and Type B compatible cards and tags using Radio
Frequency (RF). Data stored on the cards and tags is read by the Reader and transmitted
to a host. This section provides general information about the Reader. Refer to Appendix
A, B, and C for technical details.
Overview
The Reader consists of a set of printed circuit boards consisting of a Control PCA and
an Antenna PCA. The two circuit boards together contain all circuitry required to
communicate with between the host and RFID cards and tags. An optional Interface
PCA may be connected to the Control PCA to add additional Reader to Host
configurations. All circuit boards are designed to be assembled as a single module
for simple mounting, or they may be separated to accommodate space constraints.
Type A & B cards and tags do not contain internal power and are activated by the RF
power transmitted by the Reader. When a card or tag is positioned close to the
antenna the card/tag is powered and activated, and it transmits its data as a
modulated RF signal to the RF receiver. The RF receiver demodulates the signal and
sends the demodulated tag data to the microcontroller. The microcontroller collects
the tag data, decrypts it (if required), and transmits it to the host terminal. The LEDs
and beeper indicate when a tag has been read successfully.

Reader Installation
This section describes how to install the ViVOtech S500 OEM Vending Reader into a vending
or terminal system. Installation will vary depending upon the specific use of the product.
Physical Placement
Because the Reader relies on radio frequency communications, the reader can be
susceptible to electrical interference and affected by metal materials. Therefore, for
optimal performance, please observe the following important guidelines before
physically locating or mounting the Reader.
•
Do not position the Antenna PCB on any metal surface or within approximately
2 inches (5 cm.) in any direction of any grounded metal such as metal shelving,
steel beams, or electrical conduit. When attaching the Reader to a metallic face
panel frame the Antenna with a non‐metallic material as shown below to ensure
clearance with the metal.
Plastic or other non‐
metallic material

Antenna
2”

•
Do not place the Reader PCB in the near vicinity of broad spectrum EMI noise
sources (such as motors, pumps, power supplies, light dimmers, CRTs, etc.).
•
Avoid sources of RF (such as cellular telephones, portable 2‐way radios, etc.)
which may reduce the ability of the reader to communicate with the tag.
•
Make sure that all cables and wiring associated with the Reader is at least 6
inches (15 cm.) away from other cabling and wiring (such as AC power cables
from other electrical devices, computer data cabling, telephone wiring, or wiring
associated with electric‐powered locking mechanisms).

Orientation of Reader PCAs
The physical design of the Reader provides for stacking of the PCAs using standoffs
to form a single unit requiring a volume as small as 10 cu in. However, if space
constraints or mounting configurations do not support a stacked assembly the
individual PCAs may be mounted separately such as side by side. Dual mounting
holes are provided on both the Antenna PCA and Control PCA to accommodate
various mounting configurations. Additionally, the Antenna PCB contains both
horizontal (4) and vertical (3) LED placement and may be oriented as such.

Stacked Configuration
Horizontal/Separated
IMPORTANT: When configuring the Antenna and
Control boards in a stacked configuration the distance
between the two boards is critical with respect to the read
range of cards and tags. It is recommended the boards
are placed no closer than 1” (2.54 cm.) to achieve typical
read range with most cards. Some cards/tags may require
more distance between the boards. Always use non‐
metallic standoffs to connect the boards together.

Connecting to a Host
The connection from the Reader to the Host depends upon the configuration desired.
The J2 connector on the Control PCA contains all data signals along with input +5V
power. For typical RS‐232 communications or when the Reader performs as a single
Magnetic Stripe Card Reader then connect from J2 on the Control PCA to the host.
Refer to the diagram below.
If adding the Reader into a system with an existing magnetic stripe card reader then
an additional optional Interface PCA is required. With this configuration the Reader
Document: 740‐0005‐00 Rev. 1.0
Proprietary & Confidential
ViVOpay OEM S500 Technical Reference
multiplexes the card reader signals from itself and the existing card reader and
passes them to the host. The Reader is invisible to the host and behaves like the
existing magnetic card reader. This configuration requires a second cable identical to
the one connecting the existing card reader to the host. Connect the cable from the
existing card reader to the J1 connector on the Interface PCA, and connect the second
cable from the J2 connector to the host. The host does not need any other change.
Note the Host Controller must supply +5VDC to both devices.

Applying Power
The ViVOpay OEM S500 does not have a switch to turn on/off power. After
connecting the cable from the Reader to the host apply power to the host and/or
power supply. The Reader will perform a power‐up sequence as follows:
•
•
•
All LEDs will illuminate an internal self‐test is being performed.
The default RS‐232 parameters (19,200 bps, 8 data, 1 stop, no parity) will be set.
If self‐test and initialization is successful the beeper will emit two short beeps
and the leftmost LED will remain illuminated indicating the Reader is ready.
With the power‐up sequence successfully completed, the unit will read a valid card
or tag if presented and send the data to the host.

Reader Operation
This section describes how to present cards and tags to the Reader and obtain the data read
from the card.
Presenting Cards/Tags
Presenting a card or tag to the Reader so it can be read is simple. Simply bring the
card/tag within a few centimeters of the antenna. It is also OK to gently touch the
card on the antenna. Present a card/tag so that its maximum surface area is parallel
to the antenna to obtain the best read range.
If a card/tag is read successfully the beeper will emit a single beep and, if connected,
all LEDs on the Antenna PCA will illuminate (the leftmost LED remains on to
indicate power, the others illuminate briefly). If a card is not read successfully no
beep will occur nor will the LEDs flash.
Note that only one card/tag can be in the antenna’s field at a give time. Once a
card/tag has been read it must be removed from the antenna’s field (about 6 in. or 15
cm.) for at least 1 second and then presented again to be read again. However,
different cards/tags can be read at less than 0.5 second intervals.
After a card/tag has been read successfully the Reader will store its data in the buffer
and send it to the host through the RS‐232 interface, the Magnetic Card Reader
interface, and through the Strip Drive interface.
RS‐232 Operation
RS‐232 communications use the J2 signals RX and TX to send and transmit serial data
to/from the host. No flow control is used with 8 bits of data, 1 stop bit, and no parity.
Baud rates are 9600, 19200 (default), 38,400, and 57,600.
The default serial mode is “Burst” which automatically (without a host command)
transmits the data to the host when a valid card/tag is read. Refer to the ViVOPay
Serial Port Interface document for details on serial packet formatting and other serial
interface commands.

Magnetic Stripe Card Reader Emulation
The Reader emulates a Magnetic Stripe Card Reader by sending the data read from a
card/tag out as Track 1 and Track 2 data using the –IT1D, –IT1CLK, –IT2D, –IT2CLK,
and –ICP signals located at J2 on the Control PCA. The output signals are TTL (+5V)
levels.
Data read from a card/tag is sent to the host only if valid Track 1 and/or Track 2 data
is present on the card. Track 1 data is sent using the –IT1D, –IT1CLK signals; Track 2
data is sent using the –IT2D and –IT2CLK signals. Data is valid for both Track 1 and
Track 2 when the –ICP signal is active.
The timing diagram below illustrates the timing used with Magnetic Card emulation.
The timing represents an average card swiping speed of 20 cm/s.

Magnetic Strip Card Emulation
The Reader can also output Track 1 and Track 2 magnetic stripe F2F encoded data
which can be injected into the heads of a magnetic strip card reader and read by it.
Low power Track 1 and Track 2 analog data is output on the J2 Strip Drive signals
TRACK1 and TRACK2. High Power Strip Drive 9V differential signals are output on
TRACK2+ and TRACK2‐. Note that operation of the High Power Strip Drive signals
requires an additional 9VDC, 500ma. power input on J2 pin 4.
