M-2913 BlueJay Wireless Data Transceiver
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.

Power
The M-2913 gets its power from the host computer. When the M-2913 is plugged into the USB A-type
connector resident on the host, power is provided. The maximum current used by the M-2913 is 500 mA.
Configuration
The address will be set by the user application. The M-2913 must be run under Windows™ 98-SE version, or
later.
