Introduction

The AC4490 is a cost effective, high performance, frequency hopping spread spectrum transceiver designed for integration into OEM systems operating under FCC part 15.247 regulations for the 900 MHz ISM band. AC4490 transceivers provide an asynchronous TTL level serial interface for OEM Host communications, which include both system and configuration data. The Host supplies system data for transmission to other Host(s). Configuration data is stored in the on - board EEPROM. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the transceiver. To boost data integrity and security, the AC4490 uses our field - proven FHSS technology featuring optional Data - Encryption Standards (DES). Fully transparent, these transceivers operate seamlessly in serial cable replacement applications. AC4490 transceivers can operate in Point - to - Point, Point - to - Multipoint, Client - Server, or Peer - to - Peer architecture. One transceiver is configured as a server with one or many client - configured transceivers synchronized to it. To establish synchronization between transceivers, the server emits a beacon; upon detecting a beacon an RF link is established and a GPIO is toggled to signify to the host that the link is active.
