  • Utility Management THE FASTEST WAY TO WIRELESS Laird Technologies’ tiny AC4490-1x1 radio modules put the power of wireless into the smallest, most cost-sensitive applications. Despite their small size, the modules can replace a mile of cable even in harsh industrial conditions. Using field-proven FHSS 900MHz technology that utilizes an unlicensed frequency band*, AC4490-1x1s reject interference, enable co-located system operation, and ensure data integrity. With the help of a unique transparent protocol (RF232™), AC4490-1x1 integration is easy. OEMs simply solder the radio modules and antennas into place, then power-on. All frequency hopping, synchronization, and RF system data transmission/reception is performed by the radio module. The AC4490-1x1’s standard TTL interface provides bi-directional communication in point-to-point and point-to-multipoint networks. A number of on-the-fly control commands accommodate varying wireless applications.

Laird Technologies’ embedded transparent protocol simplifies the OEM’s integration process by providing drop-in design. As each radio module receives raw data, it manages the over-the-air protocol to assure successful communication. Headers, data packet length, and CRCs are not required. The RF232 supports simple cable-replacement to complex peer-to-peer configurations, broadcast communication to all radio modules or address packets to a specific destination using unique MAC addresses embedded in each radio module. RF PROTOCOL MODES a) Communication Unicast (one-to-one addressing) Broadcast (one-to-multiple addressing) b) Acknowledgement mode (ACK) API with hardware and/or software ACK indication c) One-beacon mode d) Dynamic radio data table: Retains data from up to 12 radio modules INTERFACE PROTOCOL a) On-the-fly radio module configuration: Destination address RF transmit power Co-located servers RF channel Broadcast/addressed b) Raw data or transmit/receive API c) 9-bit serial interface mode d) Long range mode, enables sensitivity control e) A/D, D/A generic I/Os f) Variable baud rate g) RF packet size, timeout control h) Onboard temperature sensor i) Handshaking, CTS/RTS, full modem-mode available j) In-range indicator k) Error detection Onboard CRC Duplicate packet filtering l) Data encryption standard (DES) SPECIFICATIONS Parameter AC4490–1x1 Interface SMT Frequency band 902-928 MHz (North America) (software selectable) Modulation FHSS FSK Serial interface options 3V TTL Serial interface data rate Up to 115.2 Kbps Output power 0mW-10mW variable (w/ 3dBi antenna) Current consumption 80mA / 28mA (transmit/receive)† Channels Up to 48 (North America) Security One-byte system ID Voltage 3.3V Sensitivity -99 dB @ full RF data rate Range (line-of-sight Up to 1 mile (1.6 km) w/ 3dBi antenna) Temperature -40º to +80ºC Humidity (non-condensing) 10% to 90% Dimensions 1.0 x 1.0 x 0.2” (2.6 x 2.6 x 0.6 cm) Weight < 0.5 oz (< 15 g) Antenna External via SMT pad *The 900MHz band is approved in the Americas and Australia as an unlicensed spectrum subject to approval by device. **For products and specifications suited to non-U.S. countries (e.g. Australia and Europe), please contact Laird Technologies directly. †Current consumption assumes 50% transmitter on-time.
