DESCRIPTION 2-8 2 2.0 DESCRIPTION 2.1 General Description The MCC-545C Packet Data Radio provides versatile communications from fixed or mobile sites. The 545C can be used for sending and receiving messages, position reporting, data logging, or other specific applications. Designed to operate over a fading groundwave and an intermittent meteor burst communications channel, the unit's low standby-power consumption (<1 watt) makes it ideal for remote locations or mobile operation.

DESCRIPTION 2-17 MCC-545C PACKET DATA RADIO 12/2000
DESCRIPTION 2-18 3.0 INSTALLATION This section provides general information on site selection and installation of the MCC-545C for operation in both an MBCS and ELOS network. 3.1 Site Selection One of the most important considerations for proper operation in a meteor burst network is the selection of the operating site. There are a number of factors to consider in selecting an optimum site: 1. 2. 3. 4. 5.
DESCRIPTION 2-19 Power Line Noise One of the main sources of external noise are high voltage power lines. Noise on these lines is generated by high voltage breakdown occurring on power line hardware such as transformers and insulators. This noise can be seen with an oscilloscope at the Receiver IF test point as a series of spikes that occur every 8 ms (1/60 Hz) or every 10 ms (1/50 Hz). The level of the spikes will be much higher than the normal background noise floor.
DESCRIPTION 2-20 3.1.2 Horizon Angle The second consideration in site selection is the horizon angle in the direction of the Master Station. To achieve optimum performance at ranges up to 1600 km (1000 miles) the horizon, or look angle, must be within 2 or 3 degrees of horizontal and must be free from obstructions, buildings, bridges, etc. Trees and shrubbery do not present a problem if they are at least 20 feet from any element of the antenna. At shorter ranges the horizon angle must be higher. 3.1.
DESCRIPTION 2-21 In an ELOS System, the higher the antenna the better. In general, every time the antenna height is doubled the system gain will be increased by approximately 6 db. Best Antenna Height 30 20 40 Mhz 45 Mhz 50 Mhz 15 10 5 500 450 400 350 300 250 200 150 0 100 Antenna Height (ft) 25 RANGE (mi) ANTENNA HEIGHT VERSUS DISTANCE BETWEEN STATIONS FIGURE 3.1 Antenna cable length must be kept as short as possible to minimize line losses.
DESCRIPTION 2-22 3.2 Equipment Installation The MCC-545C operates over a temperature range from -30°C to 60°C and is housed in a stainless steel enclosure, however, it is not waterproof. A NEMA waterproof enclosure is therefore recommended for outdoor installation when an environmentally controlled shelter is not available. To ensure proper operation, shielded cable is recommended for all connectors.
DESCRIPTION 2-23 3.2.2.1 DC Power The MCC-545C requires a power source that can deliver up to 25 amps of pulsed power (100 msec) out of a +12 VDC to +14VDC power source. The 25 amp power demand will cause a voltage drop to occur at the transmitter input, resulting in reduced transmit power, unless the power cable to the source is sized appropriately. MCC recommends using two #16 AWG wires for both the power and ground and a cable length that does not exceed 10 feet.
DESCRIPTION 2-24 Operator Port (9 Pin) I/O Port (44 Pin) Data Port (9 Pin) Aux Port (9 Pin) Data I/O Port (25 Pin) MCC PART NO. 14001352-01 3.2.2.4.1 Operator Port The Operator Port is normally connected to a local operator terminal. Use a standard RS-232 cable with a 9-pin male D connector.
DESCRIPTION 2-25 3.2.2.4.2 Data Port The Data Port is normally connected to a data logger, GPS receiver or other serial input device. Use a standard RS-232 cable with a 9-pin male D connector. Refer to Appendix B and C for more information on interfacing to data loggers or other serial input devices.

DESCRIPTION 2-28 3.3 Power-Up Sequence IMPORTANT Before applying power to the MCC-545C check all connections between the MCC-545C and the external equipment (power, antenna, operator terminal, GPS receiver and data logger).. Refer to Section 3.2.2 for complete cabling instructions. 3.3.1 Power On CAUTION Disconnect the antenna cable until the unit ID has been set (see paragraph 3.3.2). To power up the MCC-545C, apply +12VDC to the power connector.
DESCRIPTION 2-29 3.3.2 Entering the Unit ID It is very important that the unit ID is entered correctly before transmitting. If the unit transmits with the wrong ID it may conflict with another unit in the system and will result in data or messages being misrouted or lost. In addition, the network topography and statistics will receive incorrect data that will impair network performance.
DESCRIPTION 2-30 3.3.4 RF Test A very thorough RF test can be made by typing TEST[CR]. 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.
DESCRIPTION 2-31 MCC-545C PACKET DATA RADIO 12/2000
OPERATIONS 4-1 4.0 OPERATIONS This chapter covers the fundamental operating procedures of the MCC-545C and is functionally divided into seven sections: ! ! ! ! ! ! ! Getting Started Station Operational Parameters Sending and Receiving Messages Data Logging Reporting Position Location Master Mode Functions Examining System Statistics 4.1 Getting Started 4.1.1 Command Entry and Editing You must enter carriage returns after every command. A list of all the operator commands are given in Table 4.2.
OPERATIONS 4-2 Verify the ID is set correctly with the following command: ID If it is not correct, refer to section 3.3 for procedures to set it. 4.1.3 HELP Command Information about many of the MCC-545C commands can be obtained via the HELP command. Typing HELP with no parenthesis produces a single page display of the alphabetized command list. Typing “HELP,command” provides a summary explanation of how to use that particular command.
OPERATIONS 4-3 Finally, enter the SAVE command to write the configuration into the EEPROM for non-volatile storage. 4.2.1 Configuring the MCC-545C Configuration parameters include the unit ID, the Master Station assignment, I/O port functions and baud rates, transmit and receive parameters and network parameters. Commands which allow you to display/modify the configuration are marked with an * in the command table.
OPERATIONS 4-4 The third type of memory is EEPROM. It is nonvolatile and retains data even when power is removed. Special access is required to program the EEPROM therefore it is not easily corrupted. The MCC-545C can retain a copy of all the programmed configuration parameters in EEPROM. However, EEPROM is limited to 10,000 write cycles per memory location so the MCC-545C only writes to EEPROM using two special commands - "ID" and "SAVE". Only values that have changed are written into EEPROM.
OPERATIONS 4-5 MCC-545C. You will no longer be able to issue commands. Power cycling will not help either because your change will be retained in RAM, even through power cycling. However, you can always recover by removing the lid on the MCC-545C and pressing the Reset button (S1). This will reboot and restore the EEPROM settings. Alternatively, assume you want to change the operator port to MSC. You connect in ASCII protocol, command the change to MSC protocol, then switch you PC to also use MSC protocol.
OPERATIONS 4-6 TTR – Time-to-retransmit in minutes (default is 20 minutes); i.e., the message is retransmitted if it has not reached its destination within this time frame. NUP – Neighbor-up threshold (default is 20 acquisitions); the number of times a Station must hear from another Station within a one minute time interval before it becomes a neighbor.
OPERATIONS 4-7 to a node is broken. Should be as low as possible to minimize auto-connectivity traffic in the network, but large enough to not erroneously flag nodes as being offline. RELAY – MASTER OPERATION ONLY - Relay function specification (default is ON). Specifies whether the MCC-545C should act like a Remote in terms of relay functionality (i.e., does not share connectivity table with other Masters. DATAP – priority of data reports initiated at the MCC-545C (default is Y precedence).
OPERATIONS 4-8 The hourly report can be re-enabled by entering the command: HOURLIES,ON 4.2.6 Scheduling MCC-545C Events The SCHED command allows you to schedule automated command "events". An "event" simply consists of giving one or more commands a trigger time. When the MCC-545C's real-time clock reaches the trigger time, the scheduler invokes the command as though you had entered it from the MCC-545C's operator terminal.
OPERATIONS 4-9 IMPORTANT The MCC-545C currently supports up to 50 scheduled command events. The schedule list will be erased if the system software re-boots (not to be confused with power failure recovery, which will preserve the schedule list). You can schedule several command events to trigger at the same time, however, you cannot force one command to execute before or after another.
OPERATIONS 4-10 IMPORTANT The MCC-545C limits the usable frequency range to a 2 MHz bandwidth. If frequencies are to be changed outside this bandwidth then hardware modifications must also be made to the MCC545C. If the synthesizer is unable to establish phase-lock when the SYNTH,ON command is entered, the MCC-545C will respond UNLOCKED to the request and turn off the TX key. It will try once a minute thereafter to establish phase-lock.
OPERATIONS 4-11 4.2.10 Scaling A/D Readings The MCC-545C automatically scales the readings from its A/D converter for operator use. The readings that require scaling are battery level, detected RF and transmit power. The scaling factors that are required for these readings will depend on the type of hardware used at the MCC545C site and are set by operator command using the SCALE command. The SCALE commands are summarized in Table 4.1.
OPERATIONS 4-12 Messages are first entered and edited in the TEXT EDIT BUFFER. They are then transferred to one or more TX QUEUE buffers for transmission to the designated destinations. The diagram below depicts the general flow of messages within the MCC-545C software and the various commands associated with each step in the process.
OPERATIONS 4-13 There is a default destination programmed into the MCC-545C during the installation and initialization of the unit when it is first brought on-line in the network. If a message is not given a specific destination it will be sent to the default destination only. To enter a message: 1. Type MESSAGE. The operator terminal will respond with ENTER TEXT. The MCC545C will now be in the compose and edit mode. 2.
OPERATIONS 4-14 2. To Revise A Previously Entered Message To revise a previously entered message press [CTRL]T after the ENTER TEXT prompt to revise a previously entered message or to recover from an aborted session. The previous message will be displayed with the cursor placed at the end of the message. You may now resume editing the message. 3.
OPERATIONS 4-15 hh:mm:ss Message No: name:ss,nnnn chars, nnn segments hh:mm:ss ROUTING name :sss TXT sss/nn TO: name Messages are transmitted in packets and are routed to their destination in a store and forward manner, using the most efficient routing within the packet switched network. The originating station will receive an acknowledgement (ACK) if the message has been received successfully by the first routing station.
OPERATIONS 4-16 4.3.5 Sending Canned Messages The MCC-545C may be placed into a canned message mode for automatic transmission of a repetitive message to an assigned neighboring station. In the canned message mode no more than 25 messages may be placed into the Tx Queue at one time. You may either send an edited text message or a message that is randomly generated from the alphabet. To enter a canned message generated from the alphabet, enter: CANMSG,id,msg length{,min.
OPERATIONS 4-17 hh:mm:ss TXTMSG ACK name:sss, nnnn CHARS FROM name When the destination MCC-545C receives a complete message, it displays the following message: hh:mm:ss MSG RECEIVED name:sss, xxxx CHARS text……………………………… **end-of-message** where “name:sss” is the message serial number. Messages are deleted as they are displayed or printed unless they are being forwarded to further destinations. 4.3.7 Examining MESSAGE STATUS The status of all messages may be examined while they are still in the Tx Queue.
OPERATIONS 4-18 You can only examine the receive and transmit queues for neighbor stations in the network. To delete the contents of the transmit and receive queues, you must specify the exact queue by entering a station name: FLUSH TXQ,id or FLUSH RXQ,id For each message deleted, the terminal prints: Id:sss unlinked {and deleted} The “and deleted” text appears only if the message is not present in another queue.
OPERATIONS 4-19 4.9 Command Reference List MCC-545C COMMANDS All implemented MCC-545C commands are listed in Table 4.2 alphabetically for ease of reference. However, many commands are used in conjunction with others. These functional groups are given below. You may also type HELP or HELP,COMMAND to receive an explanation of any listed command.
