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, 25.0kHz and 50kHz. 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, 50kHz)

 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.

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 1.0 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, 25.0kHz and 50kHz. 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.

.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.

8. Set the radio’s basic configuration with a PC terminal through the Host system. The four essential settings for all transceivers are (See Section 3 for commands):  Frequency  Bandwidth  Modem  Power 9. In a normally operating system, you will see the CR101 POWER LED turn on at start-up. 10. Optimize the installation by checking:  Antenna aiming and RSSI check  Optimal modem rate setting 3.0 RADIO PROGRAMMING There are no manual adjustments on the radio.

.2 Regulatory Information, LN200 Module FCC Part 15 Notice This Equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment.
PAGE 6
FCC Limited Modular Approval Notice This device is offered as an FCC Licensed Limited Modular Transmitter (LMA). Applicable rule parts include Part 90, 95 and Part 80. The transmitter module is approved for use only with specific antenna, cable and output power configurations that have been tested and approved for use when installed in devices approved by third-party OEMs, or produced by the Grantee (GE MDS).
