1.0 INTRODUCTION
Note: The retail boxed version of this product includes the DLP-RFID-UHF1B reader, a
retractable USB cable, a small loop antenna, 3-foot coax and two UHF RFID tags.
The DLP-RFID-UHF1B is a low-cost, USB-powered module for reading from and writing to ISO
18000-6a, -6b and -6c intelligent RFID transponder tags. It has the ability to both read and write
data in addition to reading the unique identifier (UID). All of the DLP-RFID-UHF1B’s electronics
reside within the compact unit, and all operational power is taken from the host PC via the USB
interface.
2.0 RFID BASICS
RFID stands for Radio Frequency IDentification. It is an electronic technology whereby digital
data encoded in an RFID tag (or transponder) is retrieved utilizing a reader. In contrast to bar
code technology, RFID systems do not require line-of-sight access to the tag in order to retrieve
the tag’s data, and they are well suited to harsh environments.
An RFID tag consists of an integrated circuit attached to an antenna. In the case of the tags
used with the DLP-RFID-UHF1B, the antenna is in the form of conductive ink “printed” onto a
material that allows for connection to the integrated circuit. This type of passive (battery-free)
tag is commonly referred to as an “inlay”.
The RFID reader (or “interrogator”) is typically a microcontroller-based radio transceiver that
powers the tag with a time-varying electromagnetic radio frequency (RF) field. When the RF
field passes through the tag’s antenna, AC voltage is generated in the antenna and rectified to
supply power to the tag. Once powered, the tag can receive commands from the reader. The
information stored in the tag can then be read by the reader and sent back to the host PC for
processing.
The data in the tag consists of a hard-coded, permanent serial number (or UID) and user
memory that can be written to, read from and locked if desired. Once locked, user data can still
be read but not changed.

4.0 PERMANENT READER SERIAL NUMBER
Each DLP-RFID-UHF1B contains a unique, 32-bit, hard-coded serial number that cannot be
altered by any means. The serial number can be read via the USB interface and used to
identify the reader via the host software.
5.0 APPLICATION DEVELOPMENT
A software library is available for free download upon purchase of the DLP-RFID-UHF1B that
demonstrates reading the serial number (UID) from transponder tags, writing to the tags,
accessing the reader’s permanent serial number and controlling the integrated pass/fail beeper.
Additionally, a low-power Mode Enable command is provided to reduce current consumption to
approximately 45mA when communication with a tag is not required.

6.0 REGULATORY AGENCY CONSIDERATIONS
6.1 AGENCY IDENTIFICATION NUMBERS
Compliance with the appropriate regulatory agencies is essential in the deployment of all
transceiver devices. DLP Design will obtain modular approval for this RF product such that an
OEM need only meet a few basic requirements in order to utilize their end product under this
approval. Corresponding agency identification numbers will be listed below:
Part Number US / FCC CANADA / IC
DLP-RFID-
UHF1B SX9UHF1B 5675A-UHF1B
6.2 EXTERNAL ANTENNAS
The DLP-RFID-UHF1B will be approved for use with selected external antennas. Connection is
made via reverse-polarity SMA connectors.
A magnetic loop antenna is provided with each DLP-RFID-UHF1B reader purchased from DLP
Design as shown below:
This antenna is well suited for reading the near-field loop incorporated into many Gen-2 tags.
This antenna requires a coax cable with a reverse-polarity SMA connector at one end for
connection to the DLP-RFID-UHF1B reader. A 3-foot coax cable is provided with each DLP-
RFID-UHF1B reader purchased from DLP Design.
6.3 FCC/IC REQUIREMENTS FOR MODULAR APPROVAL
Any changes or modifications to the DLP-RFID-UHF1B’s printed circuit board or magnetic loop
antenna could void the user’s authority to operate the equipment.
6.4 WARNINGS
Rev 1.1 (April 2009) 5 © DLP Design, Inc.
Operation is subject to the following two conditions: (1) This device may not cause harmful
interference, and (2) this device must accept any interference received, including interference
that may cause undesirable operation.
This device is intended for use under the following conditions:
1. The transmitter module may not be co-located with any other transmitter or antenna; and,
2. The module will be approved using the FCC’s “unlicensed modular transmitter approval”
method. Only loop antennas which do not exhibit a directional gain greater than that of the
antenna approved with the device may be used.
As long as these two conditions are met, further transmitter testing will not be required.
However, the OEM integrator is still responsible for testing their end product for any additional
compliance measures necessitated by the installation of this module (i.e. digital device
emissions, PC peripheral requirements, etc.).
Note: In the event that these conditions cannot be met (i.e. co-location with another
transmitter), then the FCC authorization is no longer valid, and the corresponding FCC ID may
not be used on the final product. Under these circumstances, the OEM integrator will be
responsible for re-evaluating the end product (including the transmitter) and obtaining a
separate FCC authorization.
6.5 OEM PRODUCT LABELING
The final end product must be labeled in a visible area with the following text:
“Contains TX FCC ID: SX9UHF1B”
6.6 RF EXPOSURE
In order to comply with FCC RF exposure requirements, the antenna used for this transmitter
must not be co-located or operating in conjunction with any other antenna or transmitter.
6.7 ADDITIONAL INFORMATION FOR OEM INTEGRATORS
The end user should NOT be provided with any instructions on how to remove or install the
DLP-RFID-UHF1B. This device will be pre-certified to operate with the antenna models listed
below:
