![MDS LN700 Integrator’s Guide 05-6961A01, revision 2 [1] MDS LN700 Integrator’s Guide 1.0 INTRODUCTION The LN700 (Figure 1), is a fixed location (not intended for mobile use), multi-modem system operating in licensed bands between 757-758MHz and 787-788MHz (Guard Band BLOCK A), using channel bandwidths of 6.25kHz, 12.5kHz, and 25.0kHz. Available Channel Range is defined as follows: BW Min. Freq Max. Freq Low Band Range 6.25KHz 757.06875 MHz 757.93125MHz High Band Range 6.25KHz 787.06875 MHz 787.93125MHz Low Band Range 12.5KHz 757.06875 MHz 757.93125MHz High Band Range 12.5KHz 787.06875 MHz 787.93125MHz Low Band Range 25.0KHz 757.06875 MHz 757.93125MHz High Band Range 25.0KHz 787.06875 MHz 787.93125MHz Modulation choices for each bandwidth include QPSK, 16QAM, and 64QAM. Maximum power and modem speed is based on frequency, modem choice, and applicable emission mask. Transmit operation in a normal running system is governed by a Media Access Control Protocol, with distributed control functionality between AP and remotes, such that all stations act to control the emissions and operation of other stations in the system. The unit is designed for use inside data equipment to provide reliable connectivity in wireless networks. The LN700 power control circuit ensures that the RF output is linear and never exceeds +41 dBm at the antenna connector. The module is designed for OEM use only. Host systems must be professionally installed. Host systems must be factory configured by the OEM to operate at the correct frequency and output power setting. Refer to the table at the end of this guide to determine applicable antenna types and the RF output power allowed. 1.1 Transceiver Features The LN700 maximizes performance and flexibility in wireless networks, offering the following key features: Selectable frequency (757-758MHz and 787-788MHz) Selectable bandwidth (6.25kHz, 12.5kHz, 25.0kHz) Selectable modem choices (QPSK, 16QAM, 64QAM) RSSI and EVM readback indicators Store-and-Forward repeater operation Same hardware for Master, Remote, or Store-and-Forward configurations Supports RS/EIA-232(TTL), Ethernet, and USB user interfaces](https://usermanual.wiki/GE-MDS/DS-LN700/User-Guide-3084820-Page-1.png)
![MDS LN700 Integrator’s Guide 05-6961A01, revision 2 [2] Operates at 5.0 Vdc at the MiniPCIe card edge power connections and 10-60Vdc at the 3-pin power connector. Figure 1. LN700 Transceiver Module (Mini PCI-Express Card Edge for Data/Power/& I/O and J700 Antenna) NOTE: Some features may not be available on all units, based on the options purchased, or regulatory constraints in the country of operation. 2.0 INSTALLATION The transceiver is designed for installation in existing electronic equipment. The I/O and 5.0v power connections are made through the Mini PCI-Express card edge. The 10-60v power is provided through a separate 3-pin connector on the bottom of the module. The transceiver mounts to the host heatsink assembly using two #4 screws inside the RF can area. The required heatsink contact area on the bottom surface of the PCB has the solder mask removed for proper heat transfer. Only one cable connection is required to the radio for the J700 Antenna connector. The module has three optionally populated status LEDs (CR100, CR101, and CR1000) that indicate operating mode details. These LEDs provide important information that is useful during startup and optimization of the radio link. Antennas used with the radio can be either a Yagi directional type (often used at remote sites) or an omni-directional type used for short range applications or at Master stations. Contact your sales representative for information on available antennas. Follow these steps to install the transceiver module: 1. Power down the Host assembly the module is being installed in to. 2. Mate the MiniPCIe card edge of the module into the socket on the Host assembly. 3. Secure the module to the heatsink surface using two #4 screws through the mounting holes in the corners of the RF can area on the radio’s PC board. 4. Install the RF shield over the transceiver section. 5. Select and install an appropriate antenna and feedline for your system coverage requirements.](https://usermanual.wiki/GE-MDS/DS-LN700/User-Guide-3084820-Page-2.png)
