SCOPE

The scope of this document is to explain the fine points of integrating the SCM
SCR331-DI Rev 2.1b dual interface reader modules into other devices.

MOUNTING

It is recommended that the module is mounted so that the antenna is parallel to the card
placement position on the enclosure. The antenna area of the board has mounting holes.
It is recommended to use nylon (non-metallic) screws in these mounting holes. It is also
recommended that there is no metal in proximity of the antenna to ensure that signal
strength is not degraded.

CABLES & CONNECTORS

The board has four external connectors: one host USB header and three connectors for
the optional smart card reader. The USB host connector can be found under the shield.
The five pin header connects pins #1 thru #4 of the smart card connector while the four
pin header connects pins #5 thru #8 of the smart card connector. The two pin header is
connected to the card detect switch of the smart card connector. It is recommended that
none of the cables pass over the antenna region.
