Aimed at OEMs producing equipment for the Americas, the 900 MHz AC4490 module interfaces via serial TTL level connection, providing transparent bi-directional wireless communication using AeroComm's RF232 transparent protocol. Using FHSS technology, AC4490s provide interference rejection, enable co-located system operation, increases output power, and maintains data integrity. Data rate is up to 115.2 kbps. Variable output power is from 5 mW to 500 mW. The device has an adjustable receiver sensitivity from 96 dB, depending on data throughput. The device adapts across the 40°C to +80°C industrial temperature range. The AC4490 measures 1.65 inches× 1.9 inches.
