2 Overview of the MCR
The MCR200 OEM Module is an easy-to-use, economical means of introducing contact-less
smart card capability into a host. Figure 1 contains a picture of the MCR200 OEM Module.
Section 3 provides an overview of the module architecture. Section 4 provides a description
of the interface connector and pins. Section 5 provides dimensional details, section 6
describes how the MCR200 is to be mounted inside the host and Section 7 describes the
final tuning procedure.
Figure 1: MCR200 OEM Module
The MCR200 OEM module is a compact contact-less reader, which enables developers to
rapidly add contact-less functionality to new or existing products.
Each MCR200 consists of a Control Board and Antenna Board; this set is tuned and tested
at the factory prior to shipment. Each set is shipped with a 100 mm interconnecting cable as
shown in Figure 1.

DPG-00144 ERG Confidential © ERG 2004 Page 7 of 17
Revision 7 / 5 July 2004
The MCR200 serves as the data communications link between customer smart cards and
the host in which the MCR200 is installed.
For MCR-to-Card communications, the Control Board receives data signals from the host. It
then transmits the data signals via RF to a smart card held within reading distance of the
MCR200’s Antenna Board. For Card-to-MCR communications, RF data signals from the
smart card are received by the Control Board via the Antenna Board where they are sent to
the host via connector 1 located on the Control Board. Figure 2 contains a block diagram
that illustrates the MCR200 mode of operation.

Revision 7 / 5 July 2004
3 Module architecture
The Control Board contains a microprocessor, non-volatile memory, and radio frequency
transmitting and receiving circuitry. This board communicates with smart cards via a RF link
provided by the Antenna Board, and to the terminal via a TIA/EIA-485 or TIA/EIA-232 serial
protocol.
The Antenna Board consists of a printed circuit board with copper traces forming the
transmit and receive antenna. The board is attached to a ferrite plate and a metal back plate
that serves as a ground plane.
The module architecture is illustrated in Figure 3.

5 Mechanical specification
5.1 Physical Dimensions
The two components that form the MCR200 (Control and Antenna boards) are organised so
that they can be physically separated by a distance of up to 100 mm, and connected via a
connecting cable. It is possible to stack the two components into a thickness of 24.5 mm.
Figure 5: Typical stacking arrangement
5.1.1 Size
The guaranteed Reader volumetric envelope is shown in Figure 6. It is acceptable to mount
the MCR in a larger volumetric envelope if space is available.
The Control Board and Antenna have the following dimensions:
Length
(mm) Width (mm) Height (mm) Tolerance (mm)
Control Board 104 67 15.5 ± 0.5
Antenna Board 104

5.1.2 Mounting Holes
All mounting holes are M3.2. The mounting holes are aligned and may be used with screws
and plastic spacers to secure the MCR200 inside the product. The 100 mm cable allows the
Control Board and Antenna Board to be separated to accommodate different mounting
scenarios. For instance, the boards could be stacked, mounted side by side or mounted on
an angle.
Spacers between the shield and control pcb, ensure the shield remains fixed to the control
pcb, and eliminates shield deformation during assembly into the final product.

6 Mounting guidelines
These guidelines are intended to assist product designers maximise the operation of the
MCR200 in products:
• Ensure that any metalwork and/or EMC coatings are at least 15 mm away from the sides
of the antenna board in a horizontal plane and more than 5 mm below the vertical plane.
Designers should use the maximum possible clearance.
• The top of the antenna PCB (non-metallic side) must face towards the card reading
surface of the terminal and be less than 5 mm from the top surface. Any increase in this
distance will impact the Reader performance, and may result in the product being unable
to meet the project’s specifications, particularly the operating distance.
• The surface of the target area, which is directly above the Antenna Board, must be a
non-metallic surface such as plastic and be free of any metallic particles.
• It should be possible to tune the reader using the tuning capacitor shown in Figure 10
while leaving the antenna PCB fixed to the product. The product should ideally be
designed to permit re-tuning once the MCR200 is fitted.
• Removal of the shield to mount the MCR200 in ways not otherwise possible will breach
the FCC regulations and void all warranty.
• Ensure that the cable interconnecting the Antenna Board to the Control Board is located
away from metal surfaces and that the cable is fixed to avoid movement. Any movement
may degrade the reader performance, as the cable is an active part of the antenna
system.
• Ideally, both the control and antenna PCBs should be kept together as a unit.

Revision 7 / 5 July 2004
7 Antenna Tuning
The MCR200 is tuned at the factory for maximum operating range. It may be necessary to
retune the MCR200 when it is mounted into a host device to compensate for the effects of
the mounting environment (such as metallic parts or metallic paint near the antenna) and to
ensure optimum performance. For this function, use an active smart card that is initialised
for use with the particular host application.
1) With the MCR200 mounted in its operational environment place the test smart card
onto the card reading surface of the terminal. Use a non-metallic spacer with the
depth of the desired operating range. For example, if the desired operating range is
50 mm, then place a 50 mm spacer. Ensure that the host and MCR200 are powered.
2) Verify operational range by running the host internal diagnostic routines. Via the
tuning hole in the shield, adjust the tuning by rotating CV1 using a plastic tuning tool to
maximise the operating distance.
