1.0 INTRODUCTION
The DLP-RFID-LP8C is a low-cost, USB-powered module for reading from and writing to ISO15693,
ISO14443A and ISO14443B intelligent RFID transponder tags via up to eight external antennas. It has
the ability to both read and write tag user data in addition to reading the unique identifier (UID). All of the
DLP-RFID-LP8C’s electronics reside on a single, compact PCB; and all operational power is taken from
the host Windows/Windows CE/Linux PC via the USB interface. Up to eight external antennas can be
connected via reverse-polarity SMA connectors.

2.0 HARDWARE SETUP
The four jumpers provided on the DLP-RFID-LP8C module are used to select between the USB and
Rs232 interfaces. For RS232 interface operation, move the three jumpers to the RS and RS232
positions and remove JP3. For USB operation, move the three jumpers to the USB position and add
jumper JP3.
If using the RS232 interface, connect the J3 wiring terminals to ±8V to ±12V serial signals typically found
in the DB9, RS232 port connectors on a host PC. An external, regulated 5 volt power source must also
be connected to J2.
If using USB, simply connect the DLP-RFID-LP8C to a host PC using the 5-pin mini-B USB connector
CN1 and a compatible USB cable. All power and data are provided via the USB cable.
3.0 APPLICATION DEVELOPMENT
The serial interface for the DLP-RFID-LP8C operates at 115,200 baud, no parity, 8 data bits and
1 stop bit.
A demonstration GUI is provided with the purchase of a DLP-RFID-LP8C module that demonstrates the
communications protocols. Using the Virtual COM Port USB drivers, the DLP-RFID-LP8C appears to the
host PC (Windows, Linux, Mac) as an RS232 port. The GUI presents the actual control packets sent,
and the reply data coming back from the DLP-RFID-LP8C as an aid to the software developer.
3.1 DEMONSTRATION GUI
The demonstration GUI is available as a free download from the DLP Design website. The URL for the
download page is printed on the outer packaging of the DLP-RFID-LP8C.

3.2 LP8C SPECIFIC COMMANDS
To select one of the 8 external antennas on the DLP-RFID-LP8C you must send the correct command
packet (Ex: 010900030422F00000). To send this packet using the TI GUI, first make the connection to
the DLP-RFID-LP8C, and then click on the Test tab. Enter a command packet as shown below and click
on Send Raw. The LED associated with the antenna channel selected will light and successive tag reads
will use that channel.
LP8C Specific commands:

5.0 REGULATORY AGENCY CONSIDERATIONS
5.1 AGENCY IDENTIFICATION NUMBERS
Compliance with the appropriate regulatory agencies is essential in the deployment of all intentional
radiators. DLP Design has obtained 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 are listed below:
PART NUMBER
US/FCC
CAN/IC
DLP-RFID-LP8C
SX90LP8C
5675A-0LP8C
5.2 EXTERNAL ANTENNAS
The DLP-RFID1-LP8C is approved for use with external 50 Ohm loop/ferrite antennas that are resonant
at 13.56MHz. Connection is made via reverse-polarity SMA connectors.
Two different antennas are available from DLP Design: the DLP-FANT and the DLP-RFID-ANT.
DLP-FANT
DLP-RFID-ANT
The DLP-FANT ferrite-based antenna provides a compact footprint for space-constrained applications
and provides up to a 1.25-inch read range.
The DLP-FANT requires a coax cable with a reverse-polarity SMA connector at one end for connection
to the DLP-RFID-LP8C reader. This coax cable is available in a 3-foot length from DLP Design under
part number DLP-COAX1.
The DLP-RFID-ANT ships with an attached 15-foot coax cable with a reverse-polarity SMA connector
and provides up to 4 inches of read range with larger (credit card size) tags.

5.3 FCC/IC REQUIREMENTS FOR MODULAR APPROVAL
Any changes or modifications to the DLP-RFID-LP8C’s printed circuit board could void the user’s
authority to operate the equipment. Operation of an unapproved antenna could void the user’s authority
to operate the equipment.
5.4 WARNINGS
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.
To reduce potential radio interference with other users, the antenna type and its gain should be so
chosen that the equivalent isotropically-radiated power (e.i.r.p.) is not more than that permitted for
successful communication.
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 is approved using the FCC “unlicensed modular transmitter approval” method.
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.
5.5 OEM PRODUCT LABELING
The final end product must be labeled in a visible area with the following text:
“Contains TX FCC ID: SX90LP8C”
5.6 RF EXPOSURE
In order to comply with FCC RF exposure-compliance requirements, the antenna used for this transmitter
must not be co-located or operating in conjunction with any other antenna or transmitter.

5.7 ADDITIONAL INFORMATION FOR OEM INTEGRATORS
The end user should NOT be provided with any instructions on how to remove or install the DLP-RFIDLP8C. This device has been pre-certified to operate with the antenna models listed below, or any other
50 Ohm, magnetic loop antenna that resonates at 13.56MHz.
