INSTALLATION 3-1 3.0 INSTALLATION This section provides general information on site selection and installation of the 545B, as well as 545B power-up procedures. 3.1 Site Selection One of the most important considerations in the proper operation of the MBCS is the selection of the 545B-operating site. There are a number of factors, which influence selection: 1. 2. 3. 4. 5. External Noise/Interference Horizon angle DC power source Site dimensions Antenna considerations 3.1.
INSTALLATION 3-2 Power Line Noise One of the main sources of external noise are the high voltage power lines common throughout the country. Noise on these lines is generated by high voltage breakdown occurring on power line hardware such as transformers, insulators, etc. This noise shows up at the Receiver IF test point (using a scope) 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.
INSTALLATION 3-3 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 of up to 1600 km (1000 miles), the horizon or look angle must be free from obstructions, buildings, bridges, etc., and must be within 2 or 3 degrees of horizontal. Trees and other shrubbery do not present a problem if they are not within 6.1 m (20 ft) of any element of the antenna.
INSTALLATION 3-4 In a LOS or ELOS System, the higher the antenna the better. In general every time the height is double the system gain is increased by approximately 6 dB. Best Antenna Height 30 Antenna Height (ft) 25 20 40 Mhz 45 Mhz 15 50 Mhz 10 5 500 450 400 350 300 250 200 150 100 0 RANGE (mi) REMOTE STATION ANTENNA HEIGHT FOR METEOR BURST FIGURE 3.1-1 Antenna coax cable length must be kept as short as possible, to minimize line loss.
INSTALLATION 3-5 3.2 Equipment Installation Although the 545B is housed in a metal enclosure, it is not waterproof. If your application requires using the 545B outside of an environmentally controlled shelter or vehicle, you must install the 545B inside a waterproof enclosure. A NEMA enclosure is generally used in outdoor installations. The unit operates over a temperature range of -30°C to +60°C. 3.2.1 Antenna Installation MCC buys all antennas from an antenna vendor.
INSTALLATION 3-6 CONNECTOR Power Antenna Operator Port FUNCTION Input power connector, attaches to battery. BNC antenna connector. RS-232 port for connection of local operator terminal. D Connector 9S from 14001252 adapter cable. RS-232 port for connection of data logger, GPS or other serial device. D connector 9S from 14001252 adapter cable. RS-232 port for connection of GPS unit (or other serial device). Also supports MCC test equipment (pins 6, 8, 9). D Connector 9S from 14001252 adapter cable.

INSTALLATION 3-8 3.2.2.1 DC Power Connect +12 to +14VDC to the power plug that mates with the power connector on the 545B front panel. Refer to Table 3.1 for location and proper connections. Use large gauge wire (#16), since the unit can draw up to 30 Amps during transmission. The power connector can only accept #16 wires maximum. Use 2 #16 wires for positive and 2 #16 wires for negative.
INSTALLATION 3-9 IMPORTANT The AUX port connector has three extra pins (pins 6, 8, and 9) whose signals do not conform to the RS-232 standard. These are for MCC test purposes and are not used at this time. These pins will NOT interfere with a normal 3-wire RS-232 connector (pins 2, 3, and 5). 3.3 Power-Up Sequence IMPORTANT Before you apply power to the 545B, check all connections between the 545B and external equipment (power, antenna, operator terminal, GPS receiver, data logger(s), etc.).

INSTALLATION 3-11 3.3.3 Set Unit ID It is very important that the unit ID be set correctly before operation on an antenna. If the unit transmits with the wrong ID, it may conflict with another unit in the system and result in data or messages being misrouted or lost and network topography and statistics being confused.
INSTALLATION 3-12 3.3.5 Perform RF Test A simple, but very thorough RF test can be accomplished by typing TEST[CR]. TEST forces the processor to key the transmitter and check for the amount of forward and reverse RF power that is transmitted. It also checks the battery voltage under load and the antenna noise voltage.
OPERATIONS 4-1 4.0 OPERATIONS This chapter covers the fundamental operating procedures 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 Systems Statistics 4.1 Getting Started 4.1.1 Command Entry and Editing You must enter carriage returns after every command. A list of operator commands follows the operating instructions (Table 4.2).
OPERATIONS 4-2 4.1.2 Unit Name and Station ID In command descriptions, the parameter "name" is the assigned Station name. The name is the numeric Station ID. For more information on 545B operation as either a Remote or Master, refer to Section 4.2.1. Station IDs, represented by "nnnn", can be assigned as follows: 1 – 245 256 – 4095 Master Station Remote Verify the ID is set correctly: ID If it is not correct, refer to section 3.3 for procedures to set it. 4.1.
OPERATIONS 4-3 4.2 Station Operational Parameters Configure the 545B for operation in your network. Configuration requirements vary from application to application. Refer to your systems manual or consult your systems manager for correct settings. Use the CONFIG and ASSIGN commands to verify proper configurations. Use the commands described in this section to set the configuration as required. Finally, enter the SAVE command to write the configuration into the EEPROM for non-volatile storage. 4.2.
OPERATIONS 4-4 factory when the unit is first manufactured. The ROM can only be changed by replacing the chip with one programmed with the new data. Second, the RAM contains all dynamic data for the 545B. Any data logger data, positional data, messages, etc. entered into the 545B are stored in RAM. Also, any command parameters - such as configuration changes are stored in RAM. But RAM is volatile. It can only retain information while power is applied.
OPERATIONS 4-5 3. If the contents of the EEPROM is invalid - possibly because of EEPROM failure, software version in PROM is changed or and image has never been written to EEPROM, then the software will revert to the factory settings contained in the PROM. The user should beware that it is possible to "get in trouble" with this configuration process. For example, assume you accidentally set the protocol for the operator port to MSC.
OPERATIONS 4-6 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 120 minutes); i.e., the time limit for a message to reach its destination before it is deleted from the queue. The time-to-live parameter input is truncated to a 10-minute boundary for utilization by the 545B (e.g., if you enter 66 or 64, the TTL for the next message starts at 60).
OPERATIONS 4-7 are sent only over the route where the shortest transmit queues exist. (MASTER OPERATION ONLY) INF – infinity hop quantity (default 8 hops). Defines the width of the network in hops plus one to determine when connectivity 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. (MASTER OPERATION ONLY) RELAY – relay function specification (default ON).
OPERATIONS 4-8 The command MONOFF turns off the burst monitor. 4.2.5 Controlling the Hourly Statistics Report By default, an hourly statistics report is generated on the maintenance terminal port on the hour. This report consists of the same statistics reports generated by the BINS, MEM, and STAT commands. The hourly report can be disabled by entering the command: HOURLIES,OFF The hourly report can be re-enabled by entering the command: HOURLIES,ON 4.2.
OPERATIONS 4-9 NOTE The scheduler ignores certain 545B commands due to their interactive nature. The MESSAGE command is currently the only ignored command To remove command event(s) from the schedule list: SCHED,DEL,xxx where: xxx = ALL (erases entire schedule) or = schedule list number (removes single scheduled event from schedule list) IMPORTANT The 545B currently supports up to 50 scheduled command events.
OPERATIONS 4-10 SYNTH,ON You 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) IMPORTANT Componentry in the MCC-545B limits the usable frequency range to a 2 MHz bandwidth. If frequencies are to be changed outside this bandwidth, hardware modifications must also be made to the MCC-545B.
OPERATIONS 4-11 SUBST,relay_id,relay_group,remote_id,remote_group where: relay_id relay_group remote_id remote_group is the relay unit's ID is the data group report number at the relay is the originating Remote unit's ID is the data group report number at the originating Remote unit 4.2.10 Scaling A/D Readings The 545B appropriately scales readings from its A/D converter for operator use. The readings that require scaling are battery level, detected RF and transmit power.
OPERATIONS 4-12 4.3 Sending and Receiving Messages 4.3.1 Entering and Deleting Messages Entering Messages There are two ways to enter messages: 1. If you want to send a message to your 545B's default destination (set with the DESTINATION command), enter the MESSAGE command with no parameters by following these steps: a. Type MESSAGE. The computer enters the edit mode. If you decide to exit the edit mode before transmitting a message, type [CTRL]A. b.
OPERATIONS 4-13 where "p" is any letter from A to Z (A is top priority, and Z is the lowest priority). When you enter the message destinations as command parameters ("dest1", "dest2", etc.), the message is automatically routed to those Stations when you enter the message and press [ESC]. Destination is the Station numerical ID. . NOTE If you also want to send a copy of the message to your default destination, you must enter its Station numerical ID as one of the command parameters ("dest1", "dest2", etc.
OPERATIONS 4-14 where: id - numerical Station ID sss - message serial number The maintenance terminal prints the date and time, followed by MESSAGE DELETED. Other commands that you can enter to delete messages are described in Section 4.3.6. See Appendix A for a description of the printouts. 4.3.2 Sending Commands to Remote Stations Commands may be sent to any Remote Station, in the form of text messages. The commands may be any valid command for that type of Remote, except for message entry.
OPERATIONS 4-15 [DEL] Deletes the last character entered. [CTRL]R Prints the current line of text on the next line down. [CTRL]I Performs a fixed tab function. \ Removes the current line from the edit buffer. [CR] Performs a carriage return and line feed. [LF] Performs a carriage return and line feed. [CTRL]X Removes the current line from the edit buffer and places the cursor at the end of the previous line. [CTRL]T Prints the contents of the edit buffer.
OPERATIONS 4-16 If the end-to-end ACK is not received within the time-to-live limit, the 545B purges the message from the queue and print the following message: hh:mm:ss MESSAGE TIME-TO-LIVE EXPIRED, MSG.NO: sss,DESTN: name You must then reenter the message. If this printout recurs often, you should examine the performance of the equipment. Continued failure to transmit a message indicates that something is wrong with the equipment, or the link (such as too much noise interference). 4.3.
OPERATIONS 4-17 RXQ (Receive Queue) Receive queue for all messages being received. There is a separate receive queue for each neighbor Station in the network. For example, to examine message statistics from NODE5, examine the receive queue from NODE5. To examine the contents of any of the queues, type: SHOW TXQ,id or SHOW RXQ,id For the receive and transmit queues, you must specify the queue by centering either the Station ID or a wild card (-) as a parameter.
OPERATIONS 4-18 Entering the FLUSH MSG command deletes all messages in all queues for every node of the network, including connectivity and end-to-end acknowledgment messages. 4.3.7 Examining Message Status The software allows the user to examine message status. These commands display data only for your Station. Since the message queues are dynamic, this information constantly changes. After messages have been transmitted to their destinations (i.e.
OPERATIONS 4-19 Canned messages are ACKed as each message finishes transmitting to the selected neighbor. No ETE is generated. To terminate the mode, enter: CANMSG OFF,id Where "id" is the ID the messages were generating for. 4.3.9 Printing Canned Messages In the default state, canned messages do not print. To print canned messages as they are received, enter: CANMSG MODE,PRINT To turn off the print mode, enter: CANMSG MODE,NO PRINT 4.
OPERATIONS 4-20 The 545B interfaces with a number of different GPS or LORAN units and supports various GPS protocols. You can select the GPS unit and protocol you are using by entering the given parameter as part of the ASSIGN and POS commands. Refer to Appendix C for specifics on selecting and using each individual type of GPS unit with the 545B. MCC is constantly updating its list of GPS units supported by the 545B. Consult the factory for the latest list of supported devices. 4.
OPERATIONS 4-21 4. The 545B must transmit in half-duplex mode, due to its built-in T/R switch. Set transmit mode to half-duplex by typing: HALFDUPLEX IMPORTANT The 545B cannot communicate using full-duplex mode. If you place the 545B in full-duplex mode (in order to simulate a full-duplex Master), the 545B's receiver is disabled by the built-in T/R switch. The 545B can use two different "roles" when generating probe signals (see also the explanation of the P command following step 6).
OPERATIONS 4-22 Now you can generate probes using the 545B. If you are using the 545B in a pulse probe mode, you need to use the P command to generate probe signals. The P command has the following uses: P Transmit a single probe. P,? Display current pulse probe mode settings (whether or not periodic pulses are enabled, and if so, what the period is). P,x Send a single periodic probe once every "x" seconds (if you set "x" to 60, the 545B generates a single probe once a minute).
OPERATIONS 4-23 To display 545B meteor burst statistics, type: BINS To examine memory utilization, type: MEM To make the 545B send a test transmission, type: TEST These are the most common statistics commands. For information on message statistics, see Section 4.3.7. For information on meteor burst statistics, see Section 4.2.3 and Appendix A. For additional commands that are useful for maintenance purposes see the command table list at the end of this chapter. 4.
OPERATIONS 4-24 METEOR TRAIL typenet.dwg IONOSPHERE EARTHS SURFACE MASTER STATION PROBE REMOTE STATION TRANSPOND Meteor Burst MASTER STATION EARTHS SURFACE REMOTE STATION Line of Sight The Meteor Burst (MB) network is used to cover large areas. Each Master Station can cover an area up to 1,200 miles in diameter depending on many physical and data rate requirements. Each Master Station can support up to 3,840 Remote Stations.
OPERATIONS 4-25 Set up the synthesizer mode: SYNTH,ON or SYNTH,OFF 4.8.1.1.1 Full Duplex Network The Master Station(s) can be set up to communicate between themselves in a full duplex, two frequency mode. This provides a high efficiency data transfer between Masters that is about four times faster than the data rate between Remotes and Masters. Remote Stations always communicate to their Master Station in a half duplex mode.
OPERATIONS 4-26 4.8.1.1.2 Half Duplex Network Some situations require a dense connectivity between Masters and Remotes where any Remote can communicate to any Master, and any Master can communicate with any other Master. This topology requires a single Tx and Rx frequency and therefore can not operate in a full duplex mode. The Masters are set up to operate in half duplex and some contention can result between Masters that is solved by one of the following methods.
OPERATIONS 4-27 The Masters can communicate between themselves at any time since they are in complementary roles; they can communicate with their Remotes when it is their time slot to transmit idle probes. Example: ROLE, ACTIVE ROLE, PASSIVE, N Set to active role. (Master with lowest ID) Set to passive role and wait N minutes for time probe from ACTIVE Master before starting to transmit idle probes (Master with highest ID) 4.8.1.
OPERATIONS 4-28 Connectivity between Masters can be limited to prevent accidental connections that do not work well if so desired. The multi-Master network looks like: REMOTE REMOTE MASTER REMOTE MASTER REMOTE MASTER REMOTE REMOTE MASTER REMOTE CLIENT REMOTE REMOTE CLIENT CLIENT USER-A USER-B USER-C Remotes can be any combination of type with fixed or mobile connectivity. Each message must be routed to a specific destination ID.
OPERATIONS 4-29 REMOTE REPEATER REMOTE REMOTE BASE REMOTE BASE REMOTE REMOTE BASE WAN DATA CENTER HOST SERVER WAN CLIENT CLIENT CLIENT USER-A USER-B USER-C All routing from Remote to Repeater to Base is handled by the PACKET DATA RADIO software. Routing between Base Stations is handled by the WAN Data Center computer. Client applications access the central host server databases to access data and send/receive messages, email, etc.
OPERATIONS 4-30 HOSTMODE, CONTINUE Continue transmitting if Host connection lost, but use idle probes to indicate the Host connection is lost so Remotes can pick a different Master who has a host connection. Commands used are: DEVICE, MASTER ID, MM, INIT BASE, L,H REPEATER, B CONNECT, N,N,N CONNECT, OFF HOSTMODE, AAAA DESTINATION, 1 Identify unit type Define the ID (MM) of a Master ALL units must know low and high ID range for Bases. Any Repeater must know the Base to which it repeats.
OPERATIONS 4-31 idle probes from each one it receives and then selecting the one it hears the most during a specific period of time. The MCC-545B and the MCC-545 OEM Transceiver both have this capability. The MCC550B/C DAU does not, but it can operate with up to four Masters at a time. It will transmit data reports and text messages to any Master in its ID list.
OPERATIONS 4-32 4.8.2.3 Automatic Master Selection The MCC-545B has the ability to automatically select its Master based on an algorithm more suited for LOS mobile networks. When a Remote has no online Master, it monitors all the other units (Masters and Remotes) it can hear for a one minute period. All transmissions made by those units are counted and the average detected RF level for the last two transmissions for each unit is calculated.
OPERATIONS 4-33 default destination assignment for their routing destination(s). This destination is specified using the DESTINATION command: DESTINATION,OFF DESTINATION,0 DESTINATION,1 DESTINATION,D1,D2,D3,D4 Causes error in text message entry, data reports print locally and are not transmitted. Specifies source routing (see paragraph 4.8.3.1) Special Base to Host routing (see paragraph 4.8.3.
OPERATIONS 4-34 Group routing is provided in the 520B/C Master to facilitate the construction of the source routing tables. A list of source IDs can by defined by a group name, then the group name can be used in the LINK command, for example: GROUP,G1,1200,1201,1203 GROUP,G2,1300,1301,1302 LINK,1000,G1 LINK,1001,G2 LINK,2,G1,G2 The equivalent functionality is provided in a 545B Master using the SOURCE RELAY command, for example: SOURCE RELAY,2 4.8.5.
OPERATIONS 4-35 This paragraph explains how message accountability is used to guarantee that text messages get delivered to their proper destinations within an allotted time. Data reports, position reports, and remote commands/responses will not get this guarantee. They get only one chance to get through the network.
OPERATIONS 4-36 RDOWN parameter gives the number of minutes to time out a Remote neighbor. Setting NDOWN or RDOWN to “0” disables the feature (i.e., never declare neighbors down). SNP,OTL Congestion control outstanding text limit The OTL parameter specifies the maximum number of messages that will be transmitted while waiting for ETEs.
OPERATIONS 4-37 SNP,RELAY Enable/disable Master’s ability to relay messages for other destinations The 545B, when configured as a Master Station, will report all its neighbor connectivity to its neighbors with SNP,RELAY set ON. If it is set OFF, it will not report any neighbor connectivity. The OFF setting keeps neighbor units from finding alternate network paths through that node. This option should be left ON unless there is a very good reason to have it OFF for some specific customer requirement. 4.
