Do not apply voltage levels that exceed the specified voltage range. Doing so may cause fire and/or electrical shock. 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.
Be aware that any changes or modifications to this equipment not expressly approved by the party responsible for compliance (in the respective country of use) could void the user’s authority to operate the equipment. SDR-2400/SM-SDR-2400 User Guide FCC/IC approval notice, Part 15 notice | 7...
Introduction The LILEE Systems SDR-2400/SM-SDR-2400 is a MIMO 4x4 software-defined radio module for LMS- 2450-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 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: 0.25 dB Transmitter stability into VSWR: 3:1 RF ports impedance: 50 Ohms...
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 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. MIMO 4x4 mode Light Description Green, blinking @ 15 Hz (all ports) Active T/R ...
Assembly and Installation Faceplate assembly for SM-SDR-2400 Please refer to the following figures for faceplate installation. Front panel assembly SDR-2400/SM-SDR-2400 User Guide Assembly and Installation | 15...
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. Disconnect power from the LMS-2450-ME-100. 2. If you are replacing an existing smart module, remove all connections from any ports.
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...
