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-
2400 should be grounded. l Before touching components or connecting/disconnecting cables, the installer should touch a metal object to dissipate body charge. l Make sure the power is turned off and the power cord is disconnected whenever the SDR-
2400/SM-SDR-2400 is being installed or moved. l Do not apply voltage levels that exceed the specified voltage range. Doing so may cause fire and/or electrical shock. l l Do not open the chassis when the SDR-2400/SM-SDR-2400 is running: Electric shocks can occur. If considerable amounts of dust, water, or fluids enter the SDR-2400/SM-SDR-2400, turn off the power supply immediately, unplug the power cord, and contact the distributor or sales rep-
resentative. l Do not drop the SDR-2400/SM-SDR-2400 onto a hard surface. l Do not use the SDR-2400/SM-SDR-2400 in a site where the ambient temperature exceeds the rated temperature. ESD notice To prevent malfunction or damage to this product, which may be caused by electrostatic discharge
(ESD), the radio should be properly grounded at the time of installation. In addition, the installer or main-
tainer should follow proper ESD precautions, such as touching a bare metal object to dissipate body charge prior to touching components or connecting/disconnecting cables. 6 | Before You Begin 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.

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. SDR-2400/SM-SDR-2400 User Guide Interface Panel and Ports | 13 LEDstatus light descriptions The front panel of the SM-SDR-2400 has a number of LEDindicators. The following tables explain the meaning of each light, according to which radio mode is in use. MIMO 4x4 mode Light Green, blinking @ 15 Hz (all ports) Green, scanning all ports left to right @ 4 Hz Orange, solid (all ports) Orange, blinking @ 4 Hz (all ports) MIMO 2x2, all modes (dual, 1/2, or 3/4) Description Active T/R Scan mode Initialization (1s maximum) PA disabled (test mode) Light Green, solid Description May mean either:
Initialization (all ports indicated, 1s maximum) Indicated ports (1-2, 3-4, or all) ready but no active T/R l l Green, blinking @ 15 Hz Orange, blinking @ 4 Hz Orange, scanning all ports left to right @ 4 Hz Off Active T/Ron the indicated antenna ports (1-2, 3-4, or all) PAdisabled (test mode) on the indicated antenna ports Scan mode Indicated antennas (1-2 or 3-4) not in use in selected mode Power (all MIMO 2x2 and 4x4 modes) PWR Light Green Off Description Power on No power Tip: The term initialization means a driver is programming the time slot table and related registers. The process is very short, and the user should not see LED stay at initialization state for more than a second. 14 | LEDstatus light descriptions 4 Assembly and Installation Faceplate assembly for SM-SDR-2400 Please refer to the following figures for faceplate installation.

Smart module installation To install the SM-SDR-2400 smart module, follow these steps:
If you are replacing an existing smart module, remove all connections from any ports. 1. Disconnect power from the LMS-2450-ME-100. 2. 3. Unscrew the four captive screws on the existing module or blank plate. 4. Remove the module or blank plate. 5. Slide the new module into the empty bay, as shown below. The sides of the PCB rest inside the guide rails in the bay. 6. Push the module in gently until it seats. When seated correctly, the module faceplate is flush with the chassis faceplate. 7. Tighten the four captive screws on the module. 8. Power on the LMS-2450-ME-100. 9. After the chassis startup sequence, the PWR LED on the module turns green. The module is installed and ready for use. Tip: The module fits very tightly in the bay. If the module is difficult to insert, simply straighten the module and try again. SDR-2400/SM-SDR-2400 User Guide Chassis installation | 21 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. For locomotive:
Driver uses the command reg_wr to set bit 3 of $REG_CARRIER_CFG:
SDR-2400 > reg_wr $REG_CARRIER_CFG 0x0001F0F8 3. The locomotive detects the beacon and uses it to program the time slot table, then sends asso-
ciation packets to request link-up. 4. The base station exchanges device information with the locomotive (MAC address, client ID, and so forth). Then the link-up process completes. Both SDR-2400 should be able to ping each other. 22 | Configuring the SDR-2400/SM-SDR-2400 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 reg_wr $REG_FTA_CFG0 0x0036c20f reg_wr $REG_FTA_CFG0 0x0136c20f Action Set as base station Set as locomotive MIMOmodes Setting MIMO modes involves configuring transceiver and RF components. l Set bit[5] of register $REG_AD9361_CFG1 to turn on AD9361 transceiver for antenna port 1/2. l Set bit[17] of register $REG_AD9361_CFG1 to turn on AD9361 transceiver for antenna port 3/4. l The command cfg_ad9361 pa turn on/off four power amplifiers for four RF ports.
