WARNING

This equipment has been tested and found to comply with the limit requirements, pursuant to Part 15.247 of
the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when
the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate
radio frequency energy, and, if not installed and used in accordance with the instruction manual, may cause
harmful interference to radio communications. Operation of this equipment in a residential area is likely to
cause harmful interference in which case the user will be required to correct the interference at his own
expense.

Only the antenna provided is authorized for use with the M-2913. If the antenna is lost or damaged, please
contact Beckwith Electric Co., Inc. to secure a replacement antenna.

This product generates, uses, and can radiate radio frequency (RF). If it is not installed and used in
accordance with the operating instructions, it can cause harmful interference to communications. If this
equipment causes harmful interference to radio or television reception, the user should try and correct the
interference by:

• Reorienting or relocating the receiving/transmitting antenna

• Increasing the separation between the equipment and the M-2913

• Connecting the equipment into an outlet on a different circuit from the M-2913.

If these do not correct the interference, consult an experienced radio/television technician for assistance.
Correcting such interference is the responsibility of the user, not the manufacturer.

Changes or modifications not expressly approved by Beckwith Electric Co., Inc. may void the user's
authority to operate the equipment.

FCC Radiation Exposure Statement

This equipment complies with FCC radiation exposure limits set forth for uncontrolled equipment. This
equipment should be installed and operated with a minimum distance of at least 20 cm between the radiator
and person's body (excluding extremities) and must not be located or operated with any other antenna or
transmitter.

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.
