![MDSLW700Integrator’sGuide 05‐6948A01,revision3[1]MDSLW700Integrator’sGuide1.0INTRODUCTION The LW700 (Figure 1), is a fixed location (not intended for mobile use), multi-modem system operating in licensed bands between 757-758MHz and 787-788MHz, using channel bandwidths of 195kHz, 315kHz, and 570kHz. OFDM modulation choices for each bandwidth include QPSK and 16QAM variants. Maximum power and modem speed is based on frequency, modem choice, and the 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 LW700 power control circuit ensures that the RF output is linear and never exceeds +30 dBm (+/- 0.2dBm) channel power 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. 1.1TransceiverFeaturesThe LW700 maximizes performance and flexibility in wireless networks, offering the following key features: Selectable frequency (757-758MHz and 787-788MHz), see Table 5 for Center Frequency Channel Limits Selectable bandwidth (Option 4 = 195kHz, Option 3 = 315kHz, Option 2 = 570kHz) Selectable modem choices: QPSK rate ½ with 2x frequency repetition, QPSK rate ½, QPSK rate ¾, 16QAM rate ½, 16QAM rate 3/4 RSSI readback indicator 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 Operates at 5.25 Vdc at the MiniPCIe card edge power connections and 10-60Vdc at the 3-pin power connector.

![MDSLW700Integrator’sGuide 05‐6948A01,revision3[2]2.0INSTALLATION The transceiver is designed for installation in existing electronic equipment. The I/O and 5.25v 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), an omni-directional Monopole type used for short range applications or at Master stations, or a Sectorized panel type common for Master stations. See section 5.4 for Antenna Offerings and contact your sales representative for any further information. 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. 6. Connect the antenna coaxial lead to J700 on the module. It accepts a Type-TNC male coaxial connector. 7. Host Power Supply Requirements: a. Input power applied on the 52-pin connector (J1100) must be a regulated 5.25 Vdc (-/+0.05 V). b. Input power applied on 3-pin connector (J900) must not exceed the range 10.0-60.0Vdc i. Nominal Input power on J900 is in the range 12-52Vdc - FCC CFR 47 2.1055(d)(1) See Table 1 for power supply interface connections. 52-Pin GE MDS NIC Card EdgePin Description1, 6, 7, 10, 11, 13, 12, 14, 16, 19, 20, 23, 25, 28, 30, 31, 32, 33, 36, 38, 42, 44, 45, 46, 47, 48, 49, 51 GPIO (Includes Ethernet & Serial) *Consult Factory Documentation for specific details 2, 24, 39, 41, 52 +5.0V3, 5, 8, 17, 22 NC4, 9, 15, 18, 21, 26, 27, 29, 34, 35, 37, 40, 43, 50 GND Table 1.
