Compact AC4490 900MHz transceivers can replace miles of cable in harsh industrial environments. Using field-proven FHSS technology that needs no additional site licensing*, AC4490s reject interference, enable co-located system operation, increase output power and maintain data integrity. AC4490s feature drop-in installation and a number of on-the-fly control commands, providing OEMs with a versatile interface for any application. They can be used as direct wire replacements, requiring no special host software for communication. All frequency hopping, synchronization and RF system data transmission/reception is performed by the transceiver. • Lowest cost one-watt module available. AC4490 modules are socket-compatible with AeroComm’s 2.4GHz AC4424 • “Long range” mode enables 40 miles. transceivers, enabling OEMs to design once and subsequently interchange • High 900MHz data rate: 115.2 Kbps. radios to accommodate new markets, regulations and environments. • Small form factor: 1.65 x 1.9 inches. Developer tools and integration support back every transceiver line. Let • Operates in –40ºC to +80ºC temperatures.

Flexible RF Protocol AeroComm’s embedded transparent protocol simplifies the OEM’s integration process by allowing for drop-in installation. AC4490, Actual Size As each transceiver receives raw data, it manages over-theair protocol to assure successful communication. Headers, data packet length, and CRCs are not needed. RF232 supports simple cable-replacement to complex peerto-peer configurations. Broadcast communication to all transceivers or address packets to a specific destination using unique MAC addresses embedded in each transceiver.
