Hardware Prerequisites The following section shows the hardware required for the installation.  Serial or USB host system where the NSM module will connect to.  NFC module and 30 way host FFC cable  Antenna and two U.FL coax cables – If two antennas are used then there will be two set of antenna boards and four coax cables NOTE: The Antenna and the U.FL coax cables can be supplied by Access IS or the user can design the antenna using the support provided by Access IS. U.FL cables are widely available from electronics stores like RS/Farnell.
NFC Smartcard Module Hardware Installation Manual 8 CONFIDENTIAL DOCUMENT v0.2.3 5.2. Hardware Installation Steps The following details the installation steps with diagrams. 1, Turn OFF power for the host system before starting the installation 2, Connect the host system to the NFC module using the 30 way FCC cable as shown below. Please refer to Host connector section for the connector location and its pinouts. NFC moduleHost system

Antenna #0Antenna #1NSM Module 4, After the connections are done, select/verify the correct host interface selection on HOST_IFSEL_IO pins. Please refer to Host Interface Selection for HOST_IFSEL_IO pin settings. 5, If the product using the NSM module has a host cable, then a ferrite is required to be attached to the host cable. Please refer Cable Ferrite Specification for the characteristics of the required ferrite and the location of the ferrite on the host cable. NOTE : If single antenna operation is enabled, then firmware uses only Ant #1 – Port J8 and J9. Ant #0, port J2 and J3 are disabled. NOTE : Antenna coax cables are polarised. Connect the corresponding connectors with +ve markings and ground (triangle) markings on the antenna and NSM module NOTE : The cable ferrite is required to meet the FCC emissions requirement. The user should ensure that the cable ferrite is fitted in accordance to the specifications outlined in this manual. Failure to do so might void the FCC certification.
NFC Smartcard Module Hardware Installation Manual 10 CONFIDENTIAL DOCUMENT v0.2.3 6, Power up the host system or connect the host adapter to the USB/Serial port. Now, the NFC module and the smart card module should start working. If the host interface is USB, then NSM module shall start enumerating as a HID device and a smartcard reader as shown below. 7, Application software can now communicate to NSM module through USB interface or through serial communication (See Serial Communication Settings). 5.3. Software Setup Depending on the host interface selected, please refer USB or Serial software reference manual.
NFC Smartcard Module Hardware Installation Manual 11 CONFIDENTIAL DOCUMENT v0.2.3 6. Cable Ferrite Specification Each NSM module is shipped with a cable ferrite. This ferrite is required on the host cable (if any) to get the emissions levels within the acceptable limits. The cable is passed through the ferrite without any loops. The electrical specification of the ferrite is given below. The recommended ferrite is from Wurth electronics, Part number – 74 271 111. The ferrite should be located close to the device (using the NSM module) and it should be spaced 100mm from the device. The position of the ferrite can be critical with regards to the attenuation of radiated emissions. The following diagram shows a typical installation. To HostTo Device100 mmFerrite
NFC Smartcard Module Hardware Installation Manual 12 CONFIDENTIAL DOCUMENT v0.2.3 7. Hardware Connections and Pinouts There are three connectors that provides interface to the NSM module. Each of these connectors are described in detail on the following sections. 7.1. Host connector The host connector provides interface to the NSM host. Further, it also has additional signals that are brought out of the module for host mode selection and for future expansion. The following diagram shows the location of the 30 way FFC host connector and the pin#1 location. HOST connectorPIN #1 The following table shows the pinouts for the host connector.
