OVERVIEW
LX2400S FEATURES
• Simple 5V TTL level serial interface for fast integration
• Integrated Antenna saves space and reduces cost
• Frequency Hopping Spread Spectrum for security and interference
rejection
• Cost Efficient for high volume applications
• Low power consumption for battery powered implementations
• Small size for portable and enclosed applications
1. Overview
The LX2400S is a member of AeroComm’s ConnexRF OEM transceiver family. It is designed for
integration into OEM systems operating under FCC part 15.247 regulations for the 2.4 GHz ISM band.
The LX2400S is a cost-effective, high performance 2.4 GHz frequency hopping spread spectrum
transceiver. It provides an asynchronous TTL level serial interface for OEM Host communications.
Communications include both system and configuration data. The Host supplies system data for
transmission to other Host(s). Configuration data is stored in an on-board EEPROM. All frequency
hopping, synchronization, and RF system data transmission/reception is performed by the LX2400S. An
on-board antenna is integrated into the transceiver in the LX2400S-3. This antenna has coverage and gain
similar to a dipole antenna.
LX2400S operate in a Point-to-Point or Point-to-Multipoint, Client/Server architecture. One
transceiver is configured as a Server; there can be one or m any Clients. To establish synchronization
between radios, the Server emits a beacon, upon detecting the beacon, the Client transceiver informs the
Client Host and an RF link is established.
There are several data rates the OEM should be aware of:
• Serial Interface Data Rate – The LX2400S, when interfaced to an AeroComm RS232 interface board
in the SDK (or one provided by the OEM) can be configured at popular PC serial port baud rates
up to 19,200bps on the LX2400S-3 and 57,600bps on the LX2400S-10 and 115,200bps ont the
LX2400S-150.
• RF Data Rate – The LX2400S transmits data over the air at a gross rate of 144,000bps.
• Effective Data Transmission Rate – The LX2400S is a highly efficient, low-latency transceiver. See
Section 3.2.7 for more information.
This document contains information about the hardware and software interface between an
AeroComm LX2400S transceiver and an OEM Host. Information includes the theory of operation,
specifications, interface definition, and mechanical drawing.
The OEM must provide the Host hardware and software to control the radio. Certain timing
considerations must be followed. The OEM is responsible for ensuring the final product meets all FCC
and/or appropriate regulatory agency requirements before selling any product.
