1. Overview

Overview

1.1.

OverviewOverview

The AC4490 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 900 MHz ISM band.

The AC4490 is a cost-effective, high performance, 900 MHz frequency hopping spread spectrum transceiver. It provides an asynchronous TTL level serial interface for OEM Host c ommunications. 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 fre quency hopping, synchronization, and RF system data transmission/reception is performed by the transceiver.

The AC4490 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.

AC4490 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.

This document contains information about the hardware and software interface between an AeroComm AC4490 transceiver and an OEM Host. Information includes the theory of operation, specifications, interface definition, configuration information and mechanical drawing.

The OEM is responsible for e nsurin g the fin al produc t meets all F CC and/or approp riate regulat ory agency requirements listed herein before selling any product.
