1.0 INTRODUCTION
The DLP-RFS1231 is a low-cost module for transmitting and receiving digital
data via radio frequency. All of the DLP-RFS1231’s electronics (including an antenna)
reside on a single PCB, and all operational power is derived from a single 3.3 volt
supply.
The transceiver design is made up of a Renesas RL78 low-power microcontroller
(R5F100EEANA), a Semtech SX1231 low power, integrated UHF transceiver and an
antenna switch for selecting between the on-board antenna and an optional external
antenna. The hardware is designed for maximum range and optimum battery life.

3.0 SERIAL NUMBER
Each DLP-RFS1231 contains a unique, 48-bit, hard-coded serial number that cannot be altered
by any means. The serial number can be read via the microcontroller and used to identify the
transceiver in the transmitted packets.
4.0 APPLICATION DEVELOPMENT
A software library is available for free download upon purchase of the DLP-RFS1231 that
demonstrates reading the serial number, transmitting and receiving data packets and setting up
simple point-to-point and star networks.

5.0 REGULATORY AGENCY CONSIDERATIONS
5.1 AGENCY IDENTIFICATION NUMBERS
Compliance with the appropriate regulatory agencies is essential in the deployment of all
transceiver devices. DLP Design has obtained modular approval for this RF product. As such,
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-RFS1231 SX9RFS1 5675A-RFS1
5.2 EXTERNAL ANTENNAS
The DLP-RFS1231 is pre-approved for use with both its on-board chip antenna and an external
antenna part number 0600-00048 made by Laird Technologies. Connection to the external
antenna is made via a u.fl connector.
5.3 FCC/IC REQUIREMENTS FOR MODULAR APPROVAL
Any changes or modifications to the DLP-RFS1231’s printed circuit board, on-board antenna, or
pre-approved external 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.
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.
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
Rev 1.1 (April 2009) 4 © DLP Design, Inc.
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: SX9RFS1”
5.6 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.
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-RFS1231. This device will be pre-certified to operate with the antenna models listed
below:
• On-board Chip Antenna
• Laird Technologies P/N 0600-00048
