SCR331-DI OEM Integration Manual v1.2 Page 2 of 4 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.
SCR331-DI OEM Integration Manual v1.2 Page 3 of 4 LABELING If the module is integrated in such a way that the label is not visible outside, then the integrator has to display a exterior label referring to the enclosed module. The exterior label can use wording such as the following: “Contains Transmitter Module FCC ID: MBPSCR331-DI21B” or “Contains FCC ID: MBPSCR331-DI21B”. Any similar wording that expresses the same meaning may be used. TROUBLE SHOOTING 1. Unit does not power up Check to ensure that the host USB cable is plugged in at proper orientation. 2. Host displays message that device is asking for more power The device draws power from the host through the USB connector. The maximum power draw is 150mA at 5V. So the device has to be plugged into a root port or into a port on a self-powered hub. This message occurs when device is plugged into a bus-powered hub. 3. Device appears with yellow bang (!) on device manager This could happen when drivers are not found for this device or when drivers fail to load. The drivers for this device are available on Windows Update or can be downloaded from http://www.scmmicro.com. If the failure is due to driver load failure, then the reason for driver load failure can be inferred from the device manager message at the General tab. 4. Contact less cards are not detected This could happen when module is placed in proximity to something made out of metal. Ensure that there is not metal in proximity between the antenna and the card. 5. Contact card is not detected Check the connections on the two pin header. The terminals should be continuous when a card is inserted. 6. Contact card cannot be read Ensure that the cables between (both five and four pin) headers and the smart card connector are of same length and type.
SCR331-DI OEM Integration Manual v1.2 Page 4 of 4 DISCLAIMER The module has been tested and determined to be compliant with the FCC and IC rules for intentional radiators. Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
