–3–M-2911 BlueJay Universal Data TransceiverThe M-2911 Blue Jay™ Universal Data Transceiver is a self-contained short-range wireless communicationdevice (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-2911 is based on anIntersil direct sequence spread spectrum chip set that operates in the 2.4 GHz ISM band. The M-2911 designmeets the category for low power devices (LPDs) standard requirement for license-free operation.InterfaceThe M-2911 is equipped with two serial data connectors, one is a DE-9 connector for use with an RS-232serial data port and the other is a 6-pin bare wire Phoenix–type connector for use with an RS-422/RS-485(twisted shielded pair) serial data ports. Only one port can be used at a time. Each port is capable of serialdata speeds of up to 115 kbps.Data Transmission:• Error Detection – 16 bit CRC (10-5 BER at –70dBm)• Maximum throughput – 1 Mbps RF, 2400 to 115.2 Kbps interface baud rateCommunicationThe M-2911 conditions the data and transmits it over a half-duplex direct sequence spread spectrum radiooperating 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 GHzReceive:• Sensitivity – -93 dBm• Selectivity – 25 MHz■NOTE: For maximum range, all antennae must be oriented in the same plane.PowerThe M-2911 includes a self-contained switching power supply that supplies the data and RF circuitry withregulated dc power as required. The power supply has an external 3.5 mm outside diameter, 2.1 mm insidepin, center positive power input jack designed to accept the output of a UL listed wall transformer powersupply included with each unit that delivers between 7 and 60 V dc at a maximum power output of 2.5 Watts.Power Requirements:• Operating Voltage – +7 to +60 V dc• Transmit Current – 2 W (300 mA @ 7 V)• Receive Current – 2 W (300 mA @ 7 V)• Inlet Current – 1 W (150 mA @ 7 V)• Sleep Current – 0.2 W (30 mA @ 7 V)

To put the unit in AT-CommandMode:1. Connect the unit (using an RS-232 cable) to a PC or laptop computer running a terminal emulatorprogram (such as Microsoft HyperTerminal) set to 9600 bps, No Parity, One Stop Bit.2. Apply power to the unit.3. After 1–2 seconds, type "+++", and pause for 1 second or more. The M-2911 will enterAT-Command Mode and respond with "OK". The user can then enter any of the AT Commandslisted below.■NOTE: After each command, the unit will return "OK" if the command was valid, or "???" if invalid or out-of-range.AT CommandsUnit (Transmit/Receive) Address Configuration: ATS=nnn<ENTER>, where nnn is 1 to 250Destination (Transmit) Address Configuration: ATD=nnn<ENTER>, where nnn is 1 to 255Multicast (Receive) Address Configuration: ATM=nnn<ENTER>, where nnn is 251 to 254Baud Rate Select: ATB=nnnnnn<ENTER>, where nnnnnn is 2400, 4800, 9600, 19200, 38400, 76800, or115200Parity Select: ATP=x, where x is E for Even Parity, O for Odd Parity, or N for No ParityTransmit Retries Configuration: ATR=n<ENTER>, where nn is 0 to 9Interface Selection: RS-232, RS-422, or RS-485ATI=RS232<ENTER>ATI=RS422<ENTER>ATI=RS485<ENTER>RS-232 RST Configuration:ATI=RTSx<ENTER>, where x is 0 for Low, 1 for High, F for Flow-ThruATI=CTSx<ENTER>, where x is 0 for Ignore, 1 for Obey, F for Flow-Thru
