AC4490 T
The compact AC4490 900MHz transceiver can replace miles of cable in harsh industrial environments. Using field-proven
FHSS technology which needs no additional FCC licensing in the Americas, OEMs can easily make existing systems wireless
with little or no RF expertise.

The AC4490 is a member of AeroComm’s ConnexRF OEM transceiver family. 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/RS-485 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 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 AeroComm’s field-proven FHSS technology featuring optional
Data-Encryption Standards (DES).
replacement applications.
AC4490 transceivers can operate in a Point-to-Point, 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, the Client transceiver informs its Host
and an RF link is established.
