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-2910. 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-2910
• Connecting the equipment into an outlet on a different circuit from the M-2910.
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-2910 BlueJay Universal Data Transceiver
The M-2910 BlueJay™Wireless Data Transceiver is a self-contained short-range wireless communication
device (SRD) that is used for transferring serial communication data between Intelligent Electrical Device's
(IED’s) and computers hosting control software in an industrial environment. The M-2910 is based on an
Intersil direct sequence spread spectrum chip set that operates in the 2.4 GHz ISM band. The M-2910 design
meets the category for low power devices (LPDs) standard requirement for license-free operation.
Interface
The M-2910 is equipped with a dual-row, ten-pin (2 x 5) header connector utilizing a Serial Peripheral Interface
(SPI) link capable of up to 500 Kbps communication speed.
Data Transmission:
• Error Detection – 16 bit CRC (10-5 BER at –70dBm)
• Maximum throughput – 1 Mbps RF, 2400 to 115.2 Kbps interface baud rate
Communication
The M-2910 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 1 Mbps.
Transmit:
• Frequency Range – 2400 MHz to 2483.5 MHz
• Output Power – 30 mW
• Modulation – DBPSK
• Occupied Bandwidth – 20 MHz
• Spurious Emissions – 50 mV/meter
• Harmonic Emissions – 500 uV/meter
• Spreading Method – Direct Sequence 11 bit code
• Center Band – Carrier 2.450 GHz
Receive:
• Sensitivity – -93 dBm
• Selectivity – 25 MHz
The M-2910 BlueJay Wireless Data Transceiver must be used with a cable extension when the M-2910 is
mounted inside a metal enclosure. Antennas must be oriented in the same plane and located in view of the
corresponding BlueJay transceiver. Beckwith Electric cable extensions are available in 18", 6' and 13'
lengths (See Accessories).
■NOTE: For maximum range, all antennae must be oriented in the same plane.

Power
The M-2910 is powered by 5 V dc, supplied by the SPI interface connector. Maximum power draw is 1.75 W
(350 mA).
Power Requirements:
• Operating Voltage – +5 V dc &10%
• Transmit Current – 350 mA (1.75 W)
• Receive Current – 350 mA (1.75 W)
• Idle Current – 200 mA (1.00 W)
• Sleep Current – 30 mA (0.15 W)
Configuration
The M-2910 is configurable using parameters set into the M-2600A/M-2667A, using SlimCom®: The following
parameters can be set:
• Wireless Source (unit) Address (1–250)
• Wireless Destination (Transmit) Address (1–255)
• Wireless Multicast (Receive) Address (251–254)
• Peer-to-Peer Unit Addresses (1–250)
Configuring the M-2910
To configure the M-2910, the unit must be installed on an M-2600A/M-2667A control, and the control
connected to a PC running SlimCom, using a RS-232 cable. The unit may be configured through the
SlimCom menus
