cooling (no additional heat sink required).
 Custom housing for slide on bracket mounting.
2 Architecture
2.1 System Architecture
The Architecture of the 21-199765-01 is based on the Zebra Next Generation Engine RFID
reader. The reader contains a Transmitter section, Receiver section, Synthesizer section, a
Digital Modem, and a Host Interface section.
The Transmitter section contains a digital-to-analog converter (DAC), I-Q modulator, filtering, RF
power amplifier and the antenna multiplexer circuit. Communication with RFID tags is

trademarks are the property of their respective owners.
accomplished using a half-duplex signal consisting of a modulated reader signal followed by a
Continuous Wave (CW) signal. The modulated signal sends data to the tag. The tag decodes this
signal and then Backscatters (uplinks) its data during the CW portion of the cycle. The
Transmitter (downlink) modulation used for communication with RFID tags is Double Sideband
Amplitude Shift Keying (DSB-ASK) or Phase Reversal Amplitude Shift Keying (PR-ASK), depending
on tag type and reader operating mode. Data rates range from 40 to 160 kbps.
The Receiver section contains I-Q demodulator, filtering and an analog-to-digital (ADC)
converter. The Receiver architecture is direct conversion, and therefore it operates using the
same Local Oscillator (LO) frequency and RF channel used by the Transmitter. During the
Backscatter (uplink) portion of the tag communication cycle the Receiver down-converts the
modulation data from the tag to baseband, where it is amplified and low pass filtered before
being converted to a digital signal by the ADC converter. The receiver accommodates tag
Backscatter data rates range from 32 to 640 kbps, depending on tag type and reader operating
mode.
The Synthesizer section contains a voltage-controlled oscillator (VCO) and phase-locked loop.
The Synthesizer generates a Local Oscillator (LO) signal that is shared with the Transmitter and
Receiver sections. The VCO operating frequency is constrained under software control to the
902 to 928 MHz UHF ISM band when configured for the FCC region.
The Digital Modem includes the DSP, dual-function ADC-DAC converter, and general purpose
input/output communication interfaces. The Digital Modem has direct control over transceiver
functions, including operating frequency, TX power control, and generation and decoding of
baseband digital modulation data sent and received by the reader for RFID tag read and write
operations.
The Host interface section includes a microprocessor, its associated memory, and all of the
circuitry needed to implement the Ethernet interface. The host processor serves as the
interface between the radio and the outside world.

3 Hardware Interfaces
3.1 Ethernet Interface
The communication interface on the 21-199765-01 Module is a standard shielded RJ-45
connector that represents the 10/100BaseT interface. This connector also enables powering the
module with POE in accordance with 802.3af/at.
3.2 DC Power Interface
The DC Jack is adjacent to the RJ-45 connector and provides a auxiliary method of powering the
module using a Zebra approved DC Power Adapter (Zebra P/N PWRS-14000-260R)
3.3 RF Antenna Interface
The RF Interface on the 21-199765-01 Module is a custom 8-port MMCX connector (Molex P/N
73358-1170). This connector is used to interface to the RFID antenna system. The characteristic
impedance of the RF antenna interface connector is 50 ohms nominal.

5 Integration Guidelines
5.1 Mounting
The 21-199765-01 is to be mounted using a bracket that latches on to the latch on the back of the 21199765-01 Module. There is no requirement for screws or heat sinking once the bracket is installed
onto the final product. The module will slide on and latch into the bracket. Details of the bracket are
available upon request.

5.2.1 Ethernet Connection
Using a standard Cat5e/Cat6 UTP cable connect the 21-199765-01 module to an Ethernet switch or PC.
If the end application is using POE, a POE injector or Midspan should be connected between the 21199765-01 Ethernet connector and the Ethernet switch/PC.
5.2.2 Optional DC Power Connector
If POE is not the power source for the 21-199765-01 module, a DC Barrel Jack type power supply(Zebra
P/N PWRS-14000-260R) may be used to provide power to the module and the Ethernet connection can
now be made directly to the Ethernet switch or PC.
5.2.3 Antenna Connections
An RF Cable Harness similar to the one shown below is used to connect the 21-199765-01 to the System
Antenna(s). The Antenna Harness part number is Molex SD-73358-116. This harness can be used to
connect up to 8 50 ohm Antennas. The Antenna interface connection for this cable harness should be
MMCX Female.
