MDS LN200 Integrator’s Guide 1.0 INTRODUCTION The LN200 (Figure 1), is a fixed location (not intended for mobile use), multi-modem system operating in licensed bands between 216-222MHz, using channel bandwidths of 6.25kHz, 12.5kHz, and 25.0kHz. Modulation choices for each bandwidth include CPFSK, QPSK, 16QAM, and 64QAM. Maximum power and modem speed is based on frequency, modem choice, and applicable emission mask. The unit is designed for use inside data equipment to provide reliable connectivity in wireless networks. The LN200 power control circuit ensures that the RF output is linear and never exceeds +41.3 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 LN200 maximizes performance and flexibility in wireless networks, offering the following key features: Selectable frequency (216-222MHz) Selectable bandwidth (6.25kHz, 12.5kHz, 25.0kHz) Selectable modem choices (CPFSK, 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 Operates at 5.25 VDC at the MiniPCIe card edge power connections and 10-60Vdc at the 3-pin power connector. Figure 1. LN200 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. MDS LN200 Integrator’s Guide [1] 05‐6949A01, revision 2 2.0 INSTALLATION 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) 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. 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 Edge Pin Description 1, 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 2, 24, 39, 41, 52 3, 5, 8, 17, 22 4, 9, 15, 18, 21, 26, 27, 29, 34, 35, 37, 40, 43, 50 GPIO (Includes Ethernet & Serial) 3-Pin GE MDS (J900) connector Pin Description GND 2, 3 +10.0-60.0V *Consult Factory Documentation for specific details +5.25V NC GND Table 1.

LN200 User Commands MDS LN200 Integrator’s Guide [3] 05‐6949A01, revision 2 4.0 DC INPUT REQUIREMENTS 4.1 Power Consumption Ratings The module has the following nominal power consumption ratings when operated at the required (V_NIC) input voltage of 5.25 Vdc (-0.05/+0.05 V tolerance) and the required secondary input voltage of 10.0-60.0 Vdc on J900: Active Receive Mode: 130mA Transmit Mode (Worst Case Load): 1.3 Amperes Power Regulation must be met by OEM to satisfy LMA conditions: OEM Integrator should consult with Product Support for individual circuit implementations. The input voltage on the 3pin J900 connector accepts a wide range and routes to onboard regulator on the LN200 module, but the V_NIC input on the 52-pin connector must be carefully regulated. At minimum, OEM Integrators must regulate the DC voltage applied to +5.25 Vdc (V_NIC), with a tolerance of -0.05/+0.05 Vdc. This can be achieved using a voltage regulator similar to the Texas Instruments LMR12020, which is a precision DC regulator. The external +5.25 Vdc input is connected via pins 2, 24, 39, 41, and 52 of the 52 pin MiniPCIe card edge connector. The transmitter uses a closed-loop power detection circuit that ensures the peak RF power will never exceed +41.3dBm. The input voltage range of the LMR12020 device in this configuration is 10V to 15V. Using switched-mode power conversion technology, the LMR12020 can step down to voltages as low as 1.13V from a 10V input bus, with typically less than 1 W of power dissipation. The output voltage must be set to a voltage of 5.25V, using an external trim resistor. Operating features of the TI device include cycle-by-cycle current limiting, under-voltage lockout (UVLO), on/off inhibit, output overcurrent protection, and over-temperature protection. For example purposes, a circuit employing this method of regulation is shown below in schematic form. 5.0 REGULATORY AND RF OUTPUT POWER REQUIREMENTS 5.1 Technical Assistance Factory technical assistance is available by contacting GE MDS during business hours (8:30 AM to 6:00 PM Eastern Time).
