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 sys-
tem operation, increase output power and maintain data integrity.
AC4490s feature drop-in installation and a number of on-the-fly control com-
mands, 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.
AC4490 modules are socket-compatible with AeroComm’s 2.4GHz AC4424
transceivers, enabling OEMs to design once and subsequently interchange
radios to accommodate new markets, regulations and environments.
Developer tools and integration support back every transceiver line. Let
AeroComm help you find the best fit for your application.
