PRELIMINARY FCC ID: BIB61201001 INTRODUCTION 1-1 1.0 INTRODUCTION The MCC-6120 SDR PACKET DATA RADIO is used in MCC’s Network. This is an Extended Line-of-Sight (ELOS), packet switched, digital data network that operates on a single frequency in the low VHF band (40-50 MHz), a high VHF band (151-162 MHz), or a UHF band (896-901/935-940 MHz). A network has a cellular structure that uses the programmable MCC6120 SDR as a base station, a repeater and as a remote station.
PRELIMINARY FCC ID: BIB61201001 INTRODUCTION 1-2 802.11(b) access points in the infrastructure mode, or to other 802.11(b) devices in an add-hoc mode. As a remote station it can operate as a mobile unit roaming throughout the entire network, automatically linking with the nearest base station or repeater. When a remote station is installed at a fixed site it also links itself automatically to the nearest base station or repeater. The MCC-6120 SDR operates line-of-sight using groundwave.
PRELIMINARY FCC ID: BIB61201001 INTRODUCTION 1-3 functional test procedures are described that should be performed prior to placing the MCC-6120 SDR on-line within the network. 1.2 Related Documents Additional documents and application notes that may be helpful in the operation of the MCC6120 SDR Packet Radio in an ELOS Network are given below. They can be obtained from MCC or downloaded from MCC’s web site, www.meteorcomm.com. 1.2.1 MBNET 200 A Complete List of all Commands and Printouts 1.2.
PRELIMINARY FCC ID: BIB61201001 DESCRIPTION 2-4 2.0 DESCRIPTION 2.1 General The MCC-6120 SDR Packet Data Radio provides packet switched communications from fixed or mobile sites to a central Host. It can be used for sending and receiving messages, position reporting, data logging, or other custom applications. The unit is packaged in a stainless steel, weather-resistant enclosure that measures 9.5”L X 4.0”W X 4.3” H and weighs 6.0 pounds. A photograph of the MCC-6120 SDR is given in Figure 2.1-1.
PRELIMINARY DESCRIPTION 2-5 FCC ID: BIB61201001 2.2 Functionality Overview Introduction The MCC-6120 SDR is the next step in the evolution of the MCC family of Packet Data Radios. The necessity for providing customers with simple, yet powerful, fixed and mobile communications capabilities has led to the development of a Software Defined Radio (SDR) coupled to a Communications Management Unit (CMU).
PRELIMINARY FCC ID: BIB61201001 DESCRIPTION 2-6 Customer and system requirements. New device drivers have been developed to provide this same flexibility to the Ethernet and WIFI ports. For example, a laptop, tablet or palm computer can be set up to run Xtermw.exe connected through one of the Ethernet ports or WIFI (in ad-hoc mode) to operate as the maintenance terminal.
PRELIMINARY FCC ID: BIB61201001 DESCRIPTION 2-7 assigned one of the port numbers out of the given port number set when they send IP packets to the public Network. Address translation happens using the public IP address and newly assigned port number. ASCII (TELNET) The ASCII protocol is basically a dumb serial protocol transported over a TCP connection. This is useful for connections to maintenance terminals that use XTERMW.EXE as a terminal emulator.
PRELIMINARY WPA FCC ID: BIB61201001 DESCRIPTION 2-8 WIFI Protected Access – This mode also uses encryption as well as authentication. There are three WPA variations supported: PSK Pre Shared Key – A passphrase of 8-63 ASCII characters is required. The passphrase is used to generate an encryption key. This is sometimes called “WPA-Personal” (and should not be confused with different PSK modulation schemes used by the various SDR transceivers).
PRELIMINARY FCC ID: BIB61201001 DESCRIPTION 2-9 2.3 SDR Modules The MCC-6120 SDR contains four printed circuit board assemblies as shown in Figure 2.3-1. • A 32-bit Communications Management Unit (CMU) microprocessor controller performs the radio control, link and network protocol functions. This assembly also contains a digital signal processor (DSP) and a digital-to-analog converter (DAC) for generating the GMSK RF signal. The DSP also receives and demodulates the receive GMSK signals on all bands.

Data Memory The Data Memory is volatile 64 MByte RAM (16 Meg x 32). Date, time, executable programs, command parameters and program dynamic data (messages, data, position, etc) are all stored in RAM during normal operations. During normal operation, the MCC-6120 SDR software uses the data and configuration parameters stored in RAM.
PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-1 3.0 INSTALLATION Site selection and general installation guidelines are provided in this section, including instructions for cabling, antenna and power source connections. Power up procedures, initialization and preliminary functional test procedures are described that should be performed prior to placing the MCC-6120 SDR on-line within the network.
PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-2 8-10 ms to several dozen every 8-10 ms. As the number of spikes increase, the level of interference also increases. When setting up a site, always use the MM command to determine the level of the power line noise interference. It is mandatory that power line noise be avoided for an optimum site. Try to place the receiver antenna well away from power lines. NOTE Power companies are required to properly maintain their power lines to reduce noise.
PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-3 The power cable between the battery and the MCC-6120 SDR should be kept shorter than 10 feet and rated at #14 AWG or lower. (See Section 3.2.2.1 for more details.) 3.1.3 Antenna Selection Vertical polarization is used in a network to provide omni-directional coverage to all adjacent nodes in the LOS network. A good choice for a base station antenna is dual stacked dipoles mounted on two sides of a triangular tower.

PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-14 At this time all configuration data is loaded from Program Memory into RAM. This data will remain in RAM until power cycled. This is the type of message that should be displayed when you first apply power to the unit during a field installation, and for each subsequent power cycle of the radio. After power is applied to the radio all parameters that were entered and saved during the previous session will be reloaded from Flash2 memory.
PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-15 Always check with your System Administrator to determine which device type your unit should be configured as. For example, if the device should be a Remote Station and it is not currently configured properly, you can change the device type, as follows: DEVICE,REMOTE [ENTER] SAVE [ENTER] CAUTION Do not change the device type unless told to do so by your System Administrator.

PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-17 The procedure for loading the Script File is described below: 1. Install the MCC-6120 SDR MeteorComm CD (or diskette), with the Script File on it into your operator terminal, and load the Script File into your XTERMW\XTS subdirectory. 2. Start XTERMW and open a connection at the correct baud rate and COM port (typically COM1, 9600 baud). All other parameters are defaults. 3. From the Scripts drop-down menu in XTERM, choose Execute Script. 4.
PRELIMINARY FCC ID: BIB61201001 INTALLATION 3-18 3.4 Operational Test Procedure 3.4.1 RF Test A very thorough RF test can be made by entering the command TEST [ENTER]. TEST causes the processor to turn the transmitter ON and measures the forward and reverse RF power that is being transmitted. It also measures the battery voltage under load and the antenna noise voltage.
