1. Overview

Overview

1.1.

OverviewOverview

The AC4424 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 AC4424 is a cost-effective, High performance, 2.4 GHz frequency hopping spread spectrum transceiver. It provides an asynchronous TTL level se rial interfac e for OEM Host communi cations. 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 transceiver.

The AC4424 transceivers can be used as a direct serial cable replacement – requiring no special Host software for operation. They also feature a number of On-the-Fly Control Commands providing the OEM Host with a very versatile interface for any situation.

AC4424 transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server or Peer-to-Peer architecture. One transceiver is configured as a Server and there can be one or many Clients. To establish synchronization between transceivers, the Server emits a beacon. Upon detecting a beacon, a Client transceiver informs its Host and a RF link is established.

There are two data rates the OEM should be aware of:

• Serial Interface Data Rate – All transceivers can be configured to comm o n PC serial port baud rates from 110 bps to 288,000 bps.

• Effective Data Transmission Rate – The AC4424 is a highly efficient, low-latency transceiver.

This document contains information about the hardware and software interface between an AeroComm AC4424 transceiver and an OEM Host. Information includes the theory of operation, specifications, interface definition, configuration information and mechanical drawing.

The OEM is responsible for ensu ring t he fin al produc t mee ts all FCC and/o r appropriat e reg ulatory agency requirements listed herein before selling any product.
