1 Before You Begin This chapter includes safety information and legally required disclosures. Warning: Please adhere to the following safety precautions at all times. Failure to do so may result in harm to persons or property. Safety considerations l Follow electrostatic precautions whenever the SDR-2400/SM-SDR-2400 is installed. To prevent malfunction or damage which may be caused by electrostatic discharge, the SDR-2400/SM-SDR- l 2400 should be grounded.
FCC/IC approval notice, Part 15 notice Federal Communications Commission interference statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation.
RF exposure warning This equipment must be installed and operated in accordance with provided instructions and the antenna(s) used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter. End-users and installers must be provided with antenna installation instructions and transmitter operating conditions for satisfying RF exposure compliance.
2 Introduction The LILEE Systems SDR-2400/SM-SDR-2400 is a MIMO 4x4 software-defined radio module for LMS2450-ME-100 or other compatible chassis. It can be configured in either base station mode or client mode. It operates in the 2.4G Hz ISM band, with typical bandwidth of 20 MHz and data rate up to 200 Mbps.
Specifications Radio interfaces l l l l l l l l l l l l l Frequency band: 2.4000-2.4835 GHz ISM Band Channel bandwidth: 20 MHz Mode of operation: TDD/TDMA MIMO: 4x4, dual 2x2 diversity Data rate: up to 200Mbps Modulation: OFDM with BPSK, QPSK, 16 QAM, 64 QAM FEC: Convolutional code with coding rate 1/2, 2/3, 3/4, and 5/6 Power increments: 0.

3 Interface Panel and Ports This chapter presents illustrations of all connectors and ports on the SM-SDR-2400, as well as their descriptions. SM-SDR-2400 front panel view Antenna ports There are 4 TNC-female antenna connectors on the front panel. For best performance, you should use four identical antennas with same cable type and cable length. LED indicators There are five LED indicators.
LED status light descriptions The front panel of the SM-SDR-2400 has a number of LED indicators. The following tables explain the meaning of each light, according to which radio mode is in use.
4 Assembly and Installation Faceplate assembly for SM-SDR-2400 Please refer to the following figures for faceplate installation.

Complete assembly The unit should look like this when assembly is complete.
Chassis installation Please refer to LMS-2450-ME-100 Hardware Installation Guide for chassis installation. Smart module installation To install the SM-SDR-2400 smart module, follow these steps: 1. 2. 3. 4. 5. Disconnect power from the LMS-2450-ME-100. If you are replacing an existing smart module, remove all connections from any ports. Unscrew the four captive screws on the existing module or blank plate. Remove the module or blank plate. Slide the new module into the empty bay, as shown below.
Configuring the SDR-2400/SM-SDR-2400 Linking up two units To initialize and link-up two SDR-2400/SM-SDR-2400 units, follow these steps: 1. After booting up, log in and initialize RF components. 2. Configure SDR-2400/SM-SDR-2400 into base station or locomotive mode. For base station: Driver uses the command: SDR-2400 > cfg_ad9361 Then it broadcasts time slot table information via beacon packets.
Base station and client modes This is done by driver after bootup. Bit [24] of register $REG_FTA_CFG0 determines the role of a device. 0 = base station, 1 = locomotive. Command Action reg_wr $REG_FTA_CFG0 0x0036c20f Set as base station reg_wr $REG_FTA_CFG0 0x0136c20f Set as locomotive MIMO modes Setting MIMO modes involves configuring transceiver and RF components. l l l Set bit[5] of register $REG_AD9361_CFG1 to turn on AD9361 transceiver for antenna port 1/2.
