The M-2913 BlueJay

™

Wireless Data Transceiver is a self-contained short-range wireless communication

device (SRD) that is used for transferring data between a host computer and Intelligent Electrical Device

using the Universal Serial Bus (USB). The M-2913 is based on an Intersil direct sequence spread spectrum

chip set that operates in the 2.4 GHz ISM band. The M-2913 design meets the category for low power

devices (LPDs) standard requirement for license-free operation.

Interface

The M-2913 uses the standard USB B-connector to connect to the host computer. The transmission rate of

the USB using the interrupt endpoint is TBD Mbps.

Data Transmission:

• Error Detection – 16 bit CRC

• Maximum throughput – 500 Kbps

Communication

The M-2913 conditions the data and transmits it over a half-duplex direct sequence spread spectrum radio

operating in the 2.4 GHz ISM band. The over-the-air data rate is TBD Mbps.

Transmit:

• 1 Mbps

Receive:

• 1 Mbps

The M-2913 BlueJay Wireless Data Transceiver is used with a laptop or desktop computer, and if it is to be

used within a metal-enclosed structure, a cable extension must be used and the antenna mounted externally.

Antennas must be oriented in the same plane and located in view of the corresponding transceiver. Beckwith

Electric cable extensions are available in 18", 6' and 13' lengths (See Accessories).

■ NOTE: For maximum range, all antennas must be oriented in the same plane.
