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 supply voltage.

The transceiver design consists of a Semtech SX1280 low-power, integrated UHF transceiver and an

antenna switch for selecting between the on-board chip antenna and an optional external antenna.

The hardware is designed for maximum range and optimum battery life.

5.0 APPLICATION DEVELOPMENT Demonstration source code written in the C programming language is available for free download upon purchase of the DLP-RFS1280 or DLP-RFS1280ACT demonstration platform. The code was developed using Keil uVision for the STMicrocontroller Nucleo microcontroller development module. Additional information on the operation of the Semtech SX1280 transceiver IC is available in the datasheet for the SX1280. 6.

6.1.2 Press and hold button 1. While holding button 1 press and release RESET. Continue to hold button 1 until you hear the beep. Release button 1 and the system will be transmitting at 2.4GHz on the internal chip antenna with no modulation. **** Be sure to turn the volume up (blue knob next to speaker) if you cannot hear the beep. **** You can change to the external antenna by pressing button 2 - ANT-SEL. The display will show C for chip antenna and W for whip antenna.

packets to transceiver 2 which will beep with each received packet. Be sure to turn the volume up (blue knob next to speaker) if you cannot hear the beep. 7.0 REGULATORY AGENCY CONSIDERATIONS 7.1 AGENCY IDENTIFICATION NUMBERS This device complies with Part 15 of the FCC Rules. 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.

exempts de licence. L'exploitation est autorisée aux deux conditions suivantes : (1) l'appareil ne doit pas produire de brouillage, et (2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le brouillage est susceptible d'en compromettre le fonctionnement. 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event that these conditions cannot be met (i.e. co-location with another transmitter), then the FCC authorization is no longer valid, and the corresponding FCC ID may not be used on the final product.
