DESCRIPTION 2-5O&M of the MCC-545C PACKET DATA RADIO12/20001.0 INTRODUCTIONThe MCC-545B PACKET DATA RADIO is part of a Meteor Burst Communications System(MBCS) that allows short and long range communications between any two Stations in thesystem. The system offers continuous radio signal propagation via ground wave and meteorburst. Ground wave covers short distances, up to 100 km (60 miles). Meteor burst covers longerdistances, up to 1,600 km (1,000 miles), reflecting signals off ionized electron trails created bymeteors entering the atmosphere at a height of about 100 km (60 miles) above the earth's surface.These trails, called bursts, are random but predictable in number and last from a fewmilliseconds to several seconds. During this time, information can be exchanged between twoStations. The height of the trails (60 miles) gives the system its 1,000 mile range.1.1 PresentationThis manual is divided into five major sections:Section 2.

DESCRIPTION 2-8O&M of the MCC-545C PACKET DATA RADIO12/200022.0 DESCRIPTION2.1 General DescriptionThe MCC-545C Packet Data Radio provides versatile communications from fixed or mobilesites. 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 intermittentmeteor burst communications channel, the unit's low standby-power consumption (<1 watt)makes it ideal for remote locations or mobile operation.The 545C features rugged construction in a weather-resistant enclosure that measures 10.6 " x4.0" x 2.42" and weighs less than 3.5 pounds.A photograph of the 545C is given in Figure 2.1.The unit operates in a half-duplex mode and contains a solid state Tx/Rx switch that allows acommon antenna to be shared for both transmit and receive. It can be operated with a singlefrequency or on two separate frequencies.The unit utilizes three phase locked frequency synthesizers to set the Tx and Rx frequencies.The operator can set the frequency to any authorized frequency (10KHz steps) within a 2 MHzband. Authorized frequencies can only be set at the factory by trained technicians. A factorytechnician is required to retune the transmitter and synthesizer if operation outside a 2 MHz bandis desired. The unit can be factory tuned across the full 37 to 50 MHz band2.2 Send and Receive MessagesThe 545C provides full text message capability. With a portable operating terminal, or a PCrunning terminal emulation software, you can exchange messages with any other Remote Stationin the network.Messages may be plain text or binary data. They can be routed to single or multiple destinationsor, to a Host Computer or Data Center.2.3 Data LoggingThe 545C can be programmed to acquire, store, and transmit data from the various I/O signalsnoted below. Any analog or digital input can be used to trigger a transmission or to set a discreteoutput level. Output levels can also be set hi or low via a command received from a distant unit.

DESCRIPTION 2-18MCC-545C PACKET DATA RADIO12/20003.0 INSTALLATIONThis section provides general information on site selection and installation of the MCC-545C foroperation in both an MBCS and ELOS network.3.1 Site SelectionOne of the most important considerations for proper operation in a meteor burst network is theselection of the operating site. There are a number of factors to consider in selecting an optimumsite:1. External Noise/Interference2. Horizon angle3. DC power source4. Site dimensions5. Antenna considerationsThese factors are particularly important for meteor burst operation, however, many areapplicable for ELOS operation as well.3.1.1 External Noise/InterferenceNoise and signal interference can reduce the performance of the MCC-545C. The most commonsources of noise and interference are as follows:! Cosmic Noise! Power Line Noise! Automobile Ignition Noise! Computer-Generated Interference! External Signal InterferenceCosmic NoiseCosmic noise is the limiting noise factor in a meteor burst system. This noise is generated by starsystems in the galaxy and is frequency dependent. The noise is approximately 15 db abovethermal at 40 MHz and 13 db above thermal at 50 MHz. The noise is also diurnal in nature. It isthe highest when the antennas are pointed directly at the center of the galaxy and lowest whenthey are pointed at right angles to it. Daily variations of 3 to 4 db can be expected. An optimalmeteor burst site is one that is limited only by cosmic noise.The MCC-545C STAT command is very useful in determining the site antenna noise levels. TheSTAT reading should be between –120 and –115 dbm for an antenna line loss of about 1 to 2 db(100-200 ft of RG-214). The noise blanker is not effective for eliminating cosmic noise,therefore the noise readings will be the same whether the blanker is on or off.
DESCRIPTION 2-19MCC-545C PACKET DATA RADIO12/2000Power Line NoiseOne of the main sources of external noise are high voltage power lines. Noise on these lines isgenerated by high voltage breakdown occurring on power line hardware such as transformersand insulators. This noise can be seen with an oscilloscope at the Receiver IF test point as aseries of spikes that occur every 8 ms (1/60 Hz) or every 10 ms (1/50 Hz). The level of the spikeswill be much higher than the normal background noise floor. The number of spikes can vary,depending upon the level of interference, from one or two every 8-10 ms to several dozen every8-10 ms. The impulse noise blanker can remove a large amount of this noise. However, as thenumber of spikes increase, the effectiveness of the blanker is reduced. When setting up a sitealways look at the IF test point with a scope to determine the level of the power line noiseinterference. It is mandatory that power line noise be avoided for an optimum site. Try to set upthe receiver antennas well away from power lines and do not point the antennas directly towardnearby power lines.NOTE.Power companies are required to properly maintain their power lines to reduce noise. Call yourlocal utility in case of severe noise.Automobile Ignition NoiseAutomobile ignition noise is generated by all gasoline engines and is a result of the high voltagerequired to fire the spark plugs. Auto ignition noise is similar to power line noise with theexception that it does not have the 8-10 ms period which is associated with power line noise. Ifthe MCC-545C is operated on a vehicle, care must be taken to ensure that the vehicle ignitionsystem, DC motors, or any other source of electrical noise is isolated through shielding, ferritebead, and/or bypass capacitors.Computer-Generated InterferenceAll computers and printers contain high-speed circuits that generate spurious signals throughoutthe 37-50 MHz band. Interference will result if any of these signals couple into the antenna atthe MCC-545C receive frequency. To avoid this type of interference, keep the antenna awayfrom buildings that contain computers. Separating the antennas from the computers by 100 to300 feet will generally prevent this type of interference. The noise blanker will not suppresscomputer-generated interference.Signal InterferenceThis type of interference will occur whenever another transmitter is operating on the receivercenter frequency of the MCC-545C. Antenna nulling and spatial separation can be used toreduce this type on interference.
DESCRIPTION 2-20MCC-545C PACKET DATA RADIO12/20003.1.2 Horizon AngleThe second consideration in site selection is the horizon angle in the direction of the MasterStation. To achieve optimum performance at ranges up to 1600 km (1000 miles) the horizon, orlook 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 feetfrom any element of the antenna. At shorter ranges the horizon angle must be higher.3.1.3 Power SourceThe MCC-545C requires a 12 VDC power source. An automobile battery provides an excellentpower source. Care must be taken to ensure that proper wire size is used to support the MCC-545C high in-rush current during transmission. Typical transmit current is 25 to 30 amps for atime period of about .10 second. A #14 wire (or two #16 wires) should be used for both the +12VDC and ground wires. The wire length should be shorter than 10 feet. The MCC-545C does nothave an internal fuse and special care must be taken to protect the unit from a power linereversal.3.1.4 Site DimensionsTo obtain the maximum performance from a meteor burst site, the station must be set up onlevel, flat ground. The terrain in front of the antenna must be flat and free of buildings and otherstructures for a distance of at least 30 times the height of the antenna. Operation in an area thatdoes not have a proper ground plane to provide ground reflection can reduce meteor burstperformance by a factor of two.3.1.5 Antenna ConsiderationsThe final consideration in setting up a site is selecting the antenna and the co-ax cable. Theantenna must provide a 50 ohm load and this impedance must be maintained at both the Tx andRx frequency. The information bandwidth of the system is less than 15 KHz. Therefore, in asingle frequency system, a very narrow bandwidth antenna can be used.The higher the antenna gain the better the performance will be. Yagi antennas will work betterthan dipole antennas (2 to 4 times improvement). Always maintain the same antenna polarizationat the remote station as the Master Station antenna. For example, if a whip antenna is used at theMCC-545C, the Master Station antenna must also be vertically polarized.In a Meteor Burst System, the height of the antenna should be optimized as a function of thedistance between the Master Station and the Remote Station. A plot of antenna height vs. rangeis given in Figure 3.1 below.
DESCRIPTION 2-21MCC-545C PACKET DATA RADIO12/2000In an ELOS System, the higher the antenna the better. In general, every time the antenna heightis doubled the system gain will be increased by approximately 6 db.ANTENNA HEIGHT VERSUS DISTANCE BETWEEN STATIONSFIGURE 3.1Antenna cable length must be kept as short as possible to minimize line losses. Try to maintain aline loss between the antenna and the MCC-545C to less than 1 db.

DESCRIPTION 2-22MCC-545C PACKET DATA RADIO12/20003.2 Equipment InstallationThe MCC-545C operates over a temperature range from -30°C to 60°C and is housed in astainless steel enclosure, however, it is not waterproof. A NEMA waterproof enclosure istherefore recommended for outdoor installation when an environmentally controlled shelter isnot available.To ensure proper operation, shielded cable is recommended for all connectors. Also, useadequate strain relief on all cables and a weatherproof seal at the entry point of the enclosure.3.2.1 Antenna InstallationAntenna installation is very dependent on the site conditions and proper antenna placement canmake the difference between a system that works very well or one that works marginally.Always consult with MCC’s engineering department for assistance if any questions arise withrespect to proper placement of the antennas.Assembly instructions are included with each antenna. Please refer to these for proper assemblyof all antenna elements.3.2.2 Cable ConnectionsThere are a maximum of four cable connections to be made to the MCC-545C as shown below:I/ODC GPS Antenna(Optional)VHF
DESCRIPTION 2-23MCC-545C PACKET DATA RADIO12/20003.2.2.1 DC PowerThe MCC-545C requires a power source that can deliver up to 25 amps of pulsed power (100msec) out of a +12 VDC to +14VDC power source. The 25 amp power demand will cause avoltage drop to occur at the transmitter input, resulting in reduced transmit power, unless thepower cable to the source is sized appropriately. MCC recommends using two #16 AWG wiresfor both the power and ground and a cable length that does not exceed 10 feet. If a longer cableis required use #14 AWG. MCC provides a standard 6 foot power cable with lugs for connectingto a 3/8” battery post (Part No. 14001261-03).The power connector pins are as follows:The voltage drop at pins 1 and 2 should not drop by more than 2VDC during transmission.3.2.2.2 VHF AntennaConnect the antenna cable to the BNC RF connector. RG-223 may be used for cable lengthsunder 20 feet. Use a double shielded cable (RG-214) for cable lengths up to 100 feet.3.2.2.3 GPS Antenna (Optional)An external GPS antenna is required if a GPS receiver is installed in the MCC-545C. Connectthe GPS antenna cable to the SMA connector on the front panel.3.2.2.4 I/O PortThe 44 pin I/O connector on the front panel includes three RS-232 ports as one Data I/O port.MCC provides a standard cable harness that breaks out these four ports as shown below:

DESCRIPTION 2-28MCC-545C PACKET DATA RADIO12/20003.3 Power-Up SequenceIMPORTANTBefore applying power to the MCC-545C check all connections between the MCC-545C and theexternal equipment (power, antenna, operator terminal, GPS receiver and data logger).. Refer toSection 3.2.2 for complete cabling instructions.3.3.1 Power OnCAUTIONDisconnect 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.NOTEWhen the unit transmits it will draw up to 25 amps, therefore, review section 3.2.2.1 for cablingto the power source. The voltage drop at the input connector during transmission should be lessthan 2 VDC for proper operation of the unit.The following message should appear on the operator terminal when power is applied:12/23/00 16:54:10 POWER SHUTDOWN/FAIL OCCURRED.01/02/01 12:54:44 POWER HAS BEEN RESTORED... RESUMING OPERATION.+If this message does not appear then the baud rate may not be set correctly in the operatorterminal. The default baud rate setting in the MCC-545C is 9,600 baud, 8 data bits, one stop bitand no parity. This baud rate setting may be changed in the MCC-545C using the SETBAUDand SAVE commands, as described in Chapter 4.The default baud rate settings are stored in flash memory. However, it is possible to lose thesesettings if the lithium battery has lost its charge after the MCC-545C has been sitting on the shelffor an extended time period. In that event, a message similar to that shown below will appearupon start-up. METEOR BURST RADIO SUBSYSTEM MBCT (c) Copyright 2000 Meteor Communications Corp. All Rights Reserved RF Modem S/W Part Number P1060-00-00 Version 6.25 12/19/00The desired baud rate must then be entered using the SETBAUD and SAVE commands.
DESCRIPTION 2-29MCC-545C PACKET DATA RADIO12/20003.3.2 Entering the Unit IDIt is very important that the unit ID is entered correctly before transmitting. If the unit transmitswith the wrong ID it may conflict with another unit in the system and will result in data ormessages being misrouted or lost. In addition, the network topography and statistics will receiveincorrect data that will impair network performance. Use the ID Command to set the unit ID:ID,nnnnn,mmmm{,aaaaa},INITwhere nnnnn is the unit ID, mmmm is the Master Station assignment and aaaaa is the initialMaster Station connectivity setting. Obtain these numbers from your network manager. TheMCC-545C will save the ID and reboot whenever the unit is powered up or reset.3.3.3 Set and Verify the Tx/Rx FrequenciesThe MCC-545A is programmed by a factory-trained technician to operate on a number ofauthorized frequency channels. Once programmed, these frequencies can be selected by theoperator from a keyboard.You can set or display the TX and RX frequencies using the following command:FREQUENCIES, XXXX,YYYYWhere XXXX is the desired transmit frequency and YYYY is the desired receive frequencyExample: FREQUENCIES,4550,4550This will select 45.50 MHz for both the transmit and receive frequency. Only those frequenciesthat have been previously programmed into the unit at the factory can be selected.Once the frequencies are selected, confirm that the synthesizer is “ON” and locked by enteringthe following command:SYNTHESIZER, ONThe unit will respond withSYNTHESIZER, ON Locked or UnlockedIf the synthesizer returns an unlocked response, check the frequency command to ensure that theproper frequencies have been entered.NOTEThe MCC-545C will not transmit if the synthesizer is not locked.
DESCRIPTION 2-30MCC-545C PACKET DATA RADIO12/20003.3.4 RF TestA very thorough RF test can be made by typing TEST[CR]. TEST causes the processor to turnthe transmitter ON and measures the forward and reverse RF power that is being transmitted. Italso measures the battery voltage under load and the antenna noise voltage.The following response will be displayed on the operator terminal: Syncs Xmits Acks pwr-fwd pwr-rev v-bat det-RFXXXX YYYY ZZZZ AAAA BBBB CCC DDDwhere: XXXX = # of sync patterns received from the master station.YYYY = # of transmissions made by the MCC-545C.ZZZZ = # of Acknowledgements received from master station.AAAA = Forward power in watts. This should be greater than 80 watts.BBBB = Reflected power in watts. This should be less than 5 watts.CCC = Battery voltage under load (while transmitting). This should be greaterthan 10.6 VDC.DDD = Received signal strength in dbm. This will normally be the noise levelat the antenna.Troubleshooting SuggestionsIf the battery voltage is normal, the forward RF power should be at least 80 watts. If it is lowerthan 80 watts check for proper cabling to the power source. (see Section 3.2.2.1).If the reverse RF power is greater than 5 watts check the antenna and coaxial cabling for properinstallation.If both the forward and reverse power are low, the transmitter may be automatically shuttingdown due to an antenna VSWR greater than 3:1. Check the antenna and coaxial cabling forproper installation.This completes the power-up sequence of the MCC-545C. The unit is now ready for operation.Refer to Chapter 4 for detailed operating instructions.

OPERATIONS 4-1MCC-545C PACKET DATA RADIO12/20004.0 OPERATIONSThis chapter covers the fundamental operating procedures of the MCC-545C and is functionallydivided into seven sections:! Getting Started! Station Operational Parameters! Sending and Receiving Messages! Data Logging! Reporting Position Location! Master Mode Functions! Examining System Statistics4.1 Getting Started4.1.1 Command Entry and EditingYou must enter carriage returns after every command. A list of all the operator commands aregiven in Table 4.2.When a command is accepted, the operator terminal will print the system time. For a descriptionof printouts, see Appendix A.Before you begin you should familiarize yourself with the special editing functions that you canuse when entering commands:[DEL] Deletes last character entered.[CTRL] Prints command line on next line down.[CTRL]-R Repeats last command line\X Removes current line from command buffer.[CR], [LF] or [ENTER] Terminates line and causes the command entered to be executed.4.1.2 Unit Name and Station IDIn command descriptions, the parameter "name" is the assigned Station name. The name is thenumeric Station ID. For more information on MCC-545C operation as either a Remote or MasterStation, refer to Section 4.2.1. Station IDs, represented by "nnnn", can be assigned as follows:1 – 245 Master Station256 – 4095 Remote
OPERATIONS 4-2MCC-545C PACKET DATA RADIO12/2000Verify the ID is set correctly with the following command:IDIf it is not correct, refer to section 3.3 for procedures to set it.4.1.3 HELP CommandInformation 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 commandlist. Typing “HELP,command” provides a summary explanation of how to use that particularcommand. For example, typing HELP,ASSIGN explains the format to use when you enter theASSIGN command, along with a brief description of the command's function.4.1.4 System Time and DateThe system calendar is maintained during power outages. If the date and/or time shown isincorrect the calendar can be initialized with the following commands:DATE,mm/dd/yyTIME,hh:mm{:ss}The time of day maintained in the MCC-545C is transmitted to all Remote Stations keeping allunits in a network on the same time reference. If the time of day received at a Remote Stationdiffers by more than two minutes from the internal Remote clock, the Remote will set its clock tothe received time of day.To properly manage time, each Master Station and Remote Station must know how its own timezone relates to UTC and the system time. This relationship is established by relating its timezone to known reference points. UTC is always referenced to GMT; however, system time canbe referenced to any desired time zone. The time zone offset is defined with the followingcommand:TIME ZONE,UTC offset,system offset4.2 Station Operational ParametersIn order for the MCC-545C to operate correctly in your network, it must be properly configured.Configuration requirements will vary from application to application, therefore refer to yoursystems manual or consult your systems manager for correct settings.Use the commands described in this section to set the configuration as required. You may use theCONFIG and ASSIGN commands to verify proper configurations have been set.
OPERATIONS 4-3MCC-545C PACKET DATA RADIO12/2000Finally, enter the SAVE command to write the configuration into the EEPROM for non-volatilestorage.4.2.1 Configuring the MCC-545CConfiguration parameters include the unit ID, the Master Station assignment, I/O port functionsand baud rates, transmit and receive parameters and network parameters. Commands whichallow you to display/modify the configuration are marked with an * in the command table.Parameters or operational states set by these commands are retained and will determine the wayin which the MCC-545C will interact with other equipment at the site and with thecommunications network.Most configuration parameters can be viewed with the "CONFIG" and the "ASSIGN"commands. You should use these commands to verify that the configuration is correct. If it is notcorrect, use the appropriate command(s) to correct the configuration, then enter the "save"command to write the configuration parameters into the EEPROM.Saving and Restoring the Configuration - The TheoryTo aid your understanding how the MCC-545C operational configuration is saved and restored itis helpful to understand the hardware and design philosophy of the MCC-545C.The MCC-545C is designed to operate unattended in a variety of environments where powermay be applied continuously or intermittently. The goal is for the unit to continue to operatewithout loss of messages, data or configuration even if power is randomly turned on and off.Therefore the software is designed to operate continuously, to save all operational informationwhen power is off and to resume operation from that point when power is restored.To support this philosophy, the MCC-545C has three types of memory: PROM, RAM andEEPROM. The PROM is non-volatile memory that has been programmed with the MCC-545C'soperational software. This software contains the initial values of all operational parameters. Thevalues are referred to as the "factory defaults" because they are programmed in the factory whenthe unit is first manufactured. The PROM can only be modified by replacing this chip with oneprogrammed with the new data.The RAM contains all the dynamic data for the MCC-545C. All data logger data, positional data,and messages entered into the MCC-545C are stored in RAM. Also, all command parameters arestored in RAM. But RAM is volatile and can only retain information while power is applied.Turning off or disconnecting power will cause all RAM information to be lost. To prevent this, asmall internal NiCad battery is used to maintain power to the RAM when external power is off.During normal operation, the MCC-545C software operates from the data and the parametersthat are stored in RAM. Unfortunately, there are always situations when the RAM data may belost or corrupted due to total discharge of the battery, software crash or operator error. Since wedo not want to lose our configuration data during these situations, we have a third type ofmemory.
OPERATIONS 4-4MCC-545C PACKET DATA RADIO12/2000The third type of memory is EEPROM. It is nonvolatile and retains data even when power isremoved. 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-545Conly writes to EEPROM using two special commands - "ID" and "SAVE". Only values thathave changed are written into EEPROM. A validation checksum is saved in the MCC-545C toverify its data is correct.When the MCC-545C ships from the factory it programmed with the following defaultconfiguration: the Operator Port (port 0) is set for 9600 baud, 8 data bits, 1 stop bit, no parity,ASCII protocol and no flow control. This provides a known starting point for communicating tothe unit from a terminal or computer. From this starting point, the user can program the unit IDand other operational parameters and then use the "Save" command to write them to EEPROM.As soon as the parameters are entered they take effect.CAUTIONOnce the software is rebooted or restart due to a crash or failure of the battery backup RAM, allchanges will be lost unless they were previously saved in EEPROM.Saving and Restoring the Configuration - The Operation1. The software normally executes using the data and parameters stored in RAM. When theunit is turned off, or power is disconnected, the RAM information will be maintained bybattery backup. When main power is restored the unit continues operation from RAM.2. The RAM contents will be lost under the following conditions:(1) if the Reboot command is issued(2) the white Reset button (S1) is pressed(3) the internal battery backup is disconnected (by removing jumper JP1 while externalpower is off)(4) the NiCad battery fails or(5) the software crashes and restarts.The software will detect these events and will then recopy the configuration values fromEEPROM back into RAM when operation is resumed.3. The software will revert to the factory settings contained in the PROM if the contents ofthe EEPROM become invalid.The user should beware that it is possible to "get in trouble" using the configuration process. Forexample, assume you accidentally set the protocol for the operator port to MSC. If you do nothave the ability to interface using MSC protocol you will immediately lose contact with the
OPERATIONS 4-5MCC-545C PACKET DATA RADIO12/2000MCC-545C. You will no longer be able to issue commands. Power cycling will not help eitherbecause your change will be retained in RAM, even through power cycling. However, you canalways recover by removing the lid on the MCC-545C and pressing the Reset button (S1). Thiswill reboot and restore the EEPROM settings.Alternatively, assume you want to change the operator port to MSC. You connect in ASCIIprotocol, command the change to MSC protocol, then switch you PC to also use MSC protocol.Operation resumes and all is well. But do not forget to do a SAVE. If the software ever reboots,it will revert back to ASCII. And remember, once you do the SAVE you are committed to MSCprotocol. The Reset button now reboots to MSC and there is no easy way back to the factorydefault settings. You will need an MSC capability to command a change back to ASCII.4.2.2 Selecting MCC-545C Remote/Master OperationThe MCC-545C can operate as either a Remote Station or as a Master Station. Use the DEVICEcommand to select the mode you require.For normal MCC-545C Remote Station operation, enter:DEVICE,REMOTEFor MCC-545C operation as a Master Station, enter:DEVICE,MASTERNOTEAdditional MCC-545C commands are available when DEVICE,MASTER is selected. There isno help for this command.4.2.3 Selecting Network ParametersMCC recommends using the given default network parameters (values that are set on power-upor after reset). If you choose to change these parameters, first review the discussion in thisSection and in Section 4.8.5, then use the following commands to change to the desired settings:SNP{,pname,value}where "pname" is the network parameter and "value" is a limit dependent on "pname". The"pname" parameters are as follows:TTL – Time-to-live in minutes (default is 120 minutes); this is the time limit for amessage to reach its destination before it is deleted from the queue.The time-to-live parameter input is truncated to a 10-minute boundary. If youenter 60 through 69, the TTL for the next message will be 60 minutes. A resultantvalue of 0 (parameter range 0 – 9) means the message will never time out.
OPERATIONS 4-6MCC-545C PACKET DATA RADIO12/2000TTR – Time-to-retransmit in minutes (default is 20 minutes); i.e., the message isretransmitted if it has not reached its destination within this time frame.NUP – Neighbor-up threshold (default is 20 acquisitions); the number of times a Stationmust hear from another Station within a one minute time interval before itbecomes a neighbor.NDOWN – Neighbor-down threshold in minutes (default is 20 minutes); if there is nocommunication with a neighboring Station within the set time, the route to thatneighbor is ignored. Setting NDOWN to 0 maintains the routing to the neighborindefinitely.RDOWN – MASTER OPERATION ONLY - Remote-down threshold in minutes (default is1,440 minutes); if there is no communication with a Remote Station within the settime, the Remote is declared down and is removed from the Remote table.Setting RDOWN to 0 keeps a Remote defined indefinitely. OTL – Outstanding text limit (default is 20 texts); the number of messages a Station isallowed to send to another Station without an end-to-end acknowledgment.CONNP – MASTER OPERATION ONLY - Connectivity message precedence (default is 1precedence); information on changes in the connectivity table is given highestprecedence (automatic feature).ETEAP – End-to-end ACK message precedence (default is 0 [zero] precedence); theacknowledgment of a message when it reaches its final destination is givenhighest precedence.HTO – History file timeout in minutes (default is 10 minutes); maintains information forduplicate filtering.TEXTL – MASTER OPERATION ONLY - Text size in segments (default is 32 segments).FLOODP – MASTER OPERATION ONLY - Partial "flooding" precedence level (default isA precedence). Messages of this precedence level and above are transmitted overall routes of minimum length; messages below this precedence are not sent overall minimum length routes, but are sent only over the routes where the shortesttransmit queues exist.MBHOP – meteor burst link hop weight (default is 1 hop). Defines the number of networkhops to associate with a meteor burst Master Station link when determining theminimum path to use in routing a message. MBHOP should be set high enough toprevent a meteor burst Master Station link to be chosen over a line-of-sightRemote to Remote link in a network that is predominantly line-of-sight.INF – MASTER OPERATION ONLY - Infinity hop quantity (default is 8 hops).Defines the width of the network in hops plus one to determine when connectivity
OPERATIONS 4-7MCC-545C PACKET DATA RADIO12/2000to a node is broken. Should be as low as possible to minimize auto-connectivitytraffic in the network, but large enough to not erroneously flag nodes as beingoffline.RELAY – MASTER OPERATION ONLY - Relay function specification (default is ON).Specifies whether the MCC-545C should act like a Remote in terms of relayfunctionality (i.e., does not share connectivity table with other Masters.DATAP – priority of data reports initiated at the MCC-545C (default is Y precedence).When used in any data collection network, this setting defines the precedence ofdata reports generated asynchronously by the equipment itself. Typically, itshould be lower than operator entered messages and commands.4.2.4 Selecting the Burst MonitorThe MCC-545C has a unique meteor burst monitoring capability that allows monitoring thenumber of characters received, the RF signal level and other parameters on each reception.To turn on the burst monitor and to record statistics on a meteor burst link, type:MON{,d{,r}}The two optional parameters are designed to limit the printout. The burst monitor generates twoor three lines of printout for every burst. This could conceivably create hundreds of pages ofprintout a day in a network environment. The first parameter is the duration character countlimit. Only meteors lasting long enough to deliver "d" characters will be monitored. The secondparameter is the received character count limit; if at least "r" characters are received on the burst,a monitor line will be generated. The default values are 100 for "d" and 1 for "r". For example, tolimit the printout, but still receive some maintenance benefit from the monitor, enter:MON,500,100This will limit the printout to meteors that have a duration character count greater than 500, or areceived character count greater than 100. These parameters may be adjusted as desired.The command MONOFF turns off the burst monitor.4.2.5 Controlling the Hourly Statistics ReportBy default, an hourly statistics report is generated on the maintenance terminal port on the hour.This report consists of the same statistic reports generated by the BINS, MEM, and STATcommands.The hourly report can be disabled by entering the command:HOURLIES,OFF
OPERATIONS 4-8MCC-545C PACKET DATA RADIO12/2000The hourly report can be re-enabled by entering the command:HOURLIES,ON4.2.6 Scheduling MCC-545C EventsThe SCHED command allows you to schedule automated command "events". An "event" simplyconsists of giving one or more commands a trigger time. When the MCC-545C's real-time clockreaches the trigger time, the scheduler invokes the command as though you had entered it fromthe MCC-545C's operator terminal.Two different types of time trigger options are provided for command scheduling: INTERVALand TIME. The INTERVAL trigger allows you to schedule a command to be invoked at periodicintervals within a 24-hour time period; the TIME trigger allows you to schedule a command tobe invoked only once at a specified point within a 24 hour time period. The command schedulelist is restarted each time the real-time clock reaches midnight.To display the current schedule list, enter:SCHEDTo add a new command to the schedule list, enter:SCHED,type,time{OFFSET,time},commandwhere: type = INTERVAL or TIMEtime = hours:minutes:secondsOFFSET,hh:mm:ss = time offset from specified timeframe (optional)command = any MCC-545C command (with parameters)NOTEThe scheduler ignores certain commands due to their interactive nature. The MESSAGEcommand is currently the only one ignoredTo remove command event(s) from the schedule list, enter:SCHED,DEL,xxxwhere: xxx = ALL (erases entire schedule)or = schedule list number (removes single scheduled event from the schedule list)
OPERATIONS 4-9MCC-545C PACKET DATA RADIO12/2000IMPORTANTThe MCC-545C currently supports up to 50 scheduled command events. The schedule list willbe erased if the system software re-boots (not to be confused with power failure recovery, whichwill preserve the schedule list).You can schedule several command events to trigger at the same time, however, you cannotforce one command to execute before or after another. After assigning command events to theschedule, the order of commands displayed in the schedule list is the order in which the eventswill trigger for any given trigger time (i.e., an event with a low schedule number occurs beforean event with a higher schedule number).4.2.7 Setting Timeout DurationThere is one programmable time limit for the I/O port input on the MCC-545C. MCCrecommends using the pre-programmed default timeout parameter. If you choose to change thetimeout the time limits may be set by entering the number of seconds, from 0 to 32767. Enter a 0to turn off the time limit.Command DescriptionSTT,secs The Set Teleprinter Timeout command sets the time limit for characters at themaintenance terminal. Default is 60 seconds (1 minute).4.2.8 Setting FrequenciesThe FREQUENCIES command is used in systems using synthesized frequencies only (seeSection 2.7.4). To enable setting frequencies, you must first enter the following command toidentify the system as a frequency synthesized system:SYNTH,ONYou can then display/set the TX and RX frequencies using the following command:FREQ{UENCIES{,aaaa,bbbb}}where: aaaa = Tx Frequency (e.g., 4053 for 40.53 MHz)bbbb = Rx Frequency (e.g., 4153 for 41.53 MHz)
OPERATIONS 4-10MCC-545C PACKET DATA RADIO12/2000IMPORTANTThe MCC-545C limits the usable frequency range to a 2 MHz bandwidth. If frequencies are tobe changed outside this bandwidth then hardware modifications must also be made to the MCC-545C.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 tryonce a minute thereafter to establish phase-lock. If it fails, the message Synthesizer unlockedwill be displayed; if it succeeds, the MCC-545C will respond LOCKED and turn on the TX key.4.2.9 Defining Data RelaysThe ambient noise conditions at a remote station site may sometimes be excessive and a poorcommunication path to the Master Station will result particularly if the remote station isoperating in a meteor burst mode. To overcome this problem, another MCC-545C may beplaced in a nearby quiet location and used as relay station between the MCC-545C at the noisysite and its master station. When used as a relay, the MCC-545C will concentrate the datareports it receives from one or more neighboring remote sites and forwards the data to the MasterStation.When used in the relay mode,, the MCC-545C must be defined as a Master Station. The relaywill then receive MCC-550C sensor data GROUP reports (see MCC-550C Operations Manual),repackage them and forward them to the Master Station. A relay can handle a total of sixteenGROUP reports. These reports can be in any combination; i.e., four groups from each of fourRemote units, one group from each of sixteen Remote units or any combination in between.Substitution tables must be established in both the relay unit and also at the Master Station tomanage the relay function.When a designated GROUP report is received at the relay, it will substitute its own ID and groupnumber in the report as defined in its substitution table and forward the data to a MCC-520BMaster Station using the MCC-550C RF format rather than the standard MCC-545C messageformat. When the relayed data is received at the MCC-520B it reconstructs the original datareport based on its own substitution table and route the report as required.The following command is used to define the entries in the substitution table for a relay unit:SUBST,relay_id,relay_group,remote_id,remote_groupwhere: relay_id is the relay unit's IDrelay_group is the data group report number at the relayremote_id is the originating Remote unit's IDremote_group is the data group report number at the originating Remote unit
OPERATIONS 4-11MCC-545C PACKET DATA RADIO12/20004.2.10 Scaling A/D ReadingsThe MCC-545C automatically scales the readings from its A/D converter for operator use. Thereadings that require scaling are battery level, detected RF and transmit power. The scalingfactors that are required for these readings will depend on the type of hardware used at the MCC-545C site and are set by operator command using the SCALE command. The SCALEcommands are summarized in Table 4.1.There are four values that need to be scaled depending on the equipment configuration at the site:! Battery Voltage (used by the STAT/TEST commands)! Detected RF in db (used by the MM command, meteor monitor and BINS command)! Detected RF in microvolts (used by the STAT/TEST commands)! Transmit power level (used by the STAT/TEST commands)The required scaling factors are determined by the power supply used in the packet data radio.The RXTYPE command translates the receiver calibration curves from detected RF (in db) tomicrovolts. These are nonlinear and significantly different for the MCC-527 and MCC-543receivers..To apply the scaling factors, the TXPWR A/D value must first be squared and then multiplied bythe scaling factor in the table. For the other values, use the A/D reading directly and multiply bythe appropriate scaling factor.MCC-545C SCALING FACTORSPARAMETER 12V 36V 28VBAT 0.0623 0.05 0.1749DETRF 0.0188 0.1074 0.0188TXPWR 0.000353 0.00116 0.000353RXTYPE 527 543 527TABLE 4.14.3 Sending and Receiving MessagesThe MCC-545C is a packet data radio and therefore enables an operator to send and receivemessages to all nodes within the network.The messages may be entered from an operator terminal that is connected to the OPERATORPORT of the MCC-545C. There are three basic message types: (1) free-form text messages, (2)canned messages and (3) commands. The general format for all messages is shown below:MESSAGE, R , dest 1, dest 2, …dest nwhere: R = Message priority; A is highest, Z is lowest.dest = ID of the station(s) to which the message will be sent.
OPERATIONS 4-12MCC-545C PACKET DATA RADIO12/2000Messages are first entered and edited in the TEXT EDIT BUFFER. They are then transferred toone or more TX QUEUE buffers for transmission to the designated destinations.

OPERATIONS 4-13MCC-545C PACKET DATA RADIO12/2000There is a default destination programmed into the MCC-545C during the installation andinitialization of the unit when it is first brought on-line in the network. If a message is not givena 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 MCC-545C will now be in the compose and edit mode.2. Enter a message up to 3,570 characters in length, pressing [CR] at the end of each 80character line.3. Press the [ESC] key. The message will now be transferred to a Tx queue and will beautomatically transmitted to the default destination at a priority level R.The following message will be displayed, or printed, on the operator terminal:hh:mm:ss Message No: name:ss,nnnn chars, nnn segmentshh:mm:ss ROUTING name :sss TXT sss/nn TO: nameIf you wish to send a message to multiple destinations, and at a different priority level,typeMESSAGE, R, dest1, dest2, …dest nwhere: “R” is any priority level from A to Z. A is the highest and Z is the lowest.“Dest” is the numerical ID of the stations to which the message will be routed.NOTEIf you also want to send the message to your default destination you must enter its stationnumerical ID as one of the destination parameters (“dest1”, “dest2”, etc.) as specified above.NOTEIf you want to use source routing enter 0 for the destination ID. When the master stationreceives this message it will send the message to the appropriate destination based on it’s linktable showing which destination(s) are linked with your station. Refer to the master stationmanual for more information on source routing.There are three other special editing functions that may be used:1. To Retransmit A Previously Entered MessageTo retransmit a previously entered message simply depress the [ESC] key after theoperator terminal prints ENTER TEXT and before any other key is depressed. Theprevious message entered into the TEXT EDIT BUFFER will then be sent to thedestinations that are now designated in the MESSAGE command.

OPERATIONS 4-16MCC-545C PACKET DATA RADIO12/20004.3.5 Sending Canned MessagesThe MCC-545C may be placed into a canned message mode for automatic transmission of arepetitive message to an assigned neighboring station. In the canned message mode no morethan 25 messages may be placed into the Tx Queue at one time. You may either send an editedtext 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.queue depth}where “id” is the neighboring station ID, the message length is from 1 to 3000 characters and thequeue depth is from 1 to 25. The default queue depth is 5. Additional canned messages will beinjected if the number of canned messages in the queue falls below the minimum queue depth.To enter an edited canned message, enter:CANMSG,idwhere “id” is the neighboring station’s ID. After composing your message press the [ESC] key.The MCC-545C will automatically route up to 25 copies of the canned message to thedestination station.Each canned message will be acknowledged by the selected neighboring station. No end-to-endacknowledgement will be received.To terminate the mode, enter:CANMSG OFF,idCanned messages are normally not printed at destination station. To print canned messages asthey are received, enter:CANMSG MODE,PRINTTo turn off the print mode, enter:CANMSG MODE,NO PRINT4.3.6 Receiving MessagesWhen a new message is received it is announced by the following display:hh:mm:ss RECEIVING name:sss TXT sss/nn FROM name ROUTED TO: nameThe MCC-545C then generates an ACK of the message packet and transmits the ACK to theneighbor from whom the message was received:

(Note: oncean ETE is received for a message it is deleted from the queue).To examine a message, enter:SMS {,ID}4.3.8 Examining and Revising Message QueuesThere are two types of queues for transmitting and receiving messages:QUEUE NAME DESCRIPTIONTXQ(Transmit Queue)This queue is used for transmitting all messages. There isa separate transmit queue for each neighboring station inthe network. For example, if you enter a message forDEST1 That message is placed in DEST1’s transmitqueue.RXQ(Receive Queue)This queue is used for all received messages. There is aseparate receive queue for each neighboring station in thenetwork. For example, to examine message statistics fromNODE5, examine the receive queue from NODE5.To examine the contents of either queue, type:SHOW TXQ,ID or SHOW RXQ,IDYou must specify the queue by entering the station ID. For example, SHOW TXQ,006 printsstatistics for all messages being transmitted to station 006.
OPERATIONS 4-18MCC-545C PACKET DATA RADIO12/2000You 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 byentering a station name:FLUSH TXQ,id or FLUSH RXQ,idFor 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. When allmessages have been deleted, the terminal prints:queue flushedTo delete a specific message, enter:DEL MSG,id:sssThe terminal prints:Message deletedTo delete all messages from all queues, enter:FLUSH MSGFor each message deleted, the terminal prints:Id:sss deletedEntering the FLUSH MSG command deletes all messages in all queues for every node of thenetwork, including connectivity and end-to-end acknowledgment messages.
