8 Operating the PCIe M.2 Module
Once the required hardware connections are made to the PCIe M.2 Module, the unit can be operated with
simple software routines running on the OEM’s host processor. The host software issues commands to
configure the reader, set the reader’s idle mode and to start and stop various Gen2 RFID reader operations.
An example of the sequence of events starting at reader power-up is:
1. Apply 3.135V~4.4V power to the PCIe M.2 Module.
2. Establish a connection to the device via the host software.
3. Configure the reader. Critical parameters are:
a. Region of operation
When configured for a specific region, the PCIe M.2 Module can operate only according to the air
interface standards for that region. Key communication parameters are not adjustable by the user but
are inherent in the PCIe M.2 Module firmware. The FCC regional operation is the default for the device.
NOTE: The OEM is strictly forbidden to operate the PCIe M.2 Module in a regional mode other than
that in which the device is located. Applicable agency certification must be obtained by the OEM for
their product to operate in the region in which it is located. The modular certification of the PCIe M.2
Module in the U.S. may only be utilized by OEM’s that follow all guidelines set forth in this document.
b. RF output power
The PCIe M.2 Module output power must be set to a level between 10 and 27dBm. The default power
is set to the reader’s maximum allowable of 27dBm.
4. Initiate an RFID operation.
Gen2 RFID operations including Inventory, Read, Write, Lock and Kill are initiated with a command.
5. Set the PCIe M.2 Module standby mode.
When the PCIe M.2 Module is not executing an RFID operation, it assumes a low power state until another
RFID function is initiated by the host.
