Introduction This manual outlines the operation of the MCC-545C Packet Data Radio through software revision 6.87. The MCC-545C Packet Data Radio is used in MCC’s FleetTrak™ network. This chapter briefly describes this network application; refer also to Appendix F for a complete discussion of MCC Network Interoperability. In addition to information and instructions for line of sight applications, this manual also contains information regarding meteor burst master and remote station installation and refers to antennas used in those installations that apply to use of the MCC-545B or other MCC models. Please refer to the tables in the MCC-545C RF Energy Exposure Guide for lists of antenna types suitable for use in vertically-polarized line of sight applications of the MCC-545C. Each MCC-545C features rugged construction and is packaged in a stainless steel, weather-resistant enclosure that measures 10.6"L x 4.0"W x 2.42"H and weighs 3.5 pounds, as shown in Figure 1.1.

The FleetTrak network is shown in Figure 1.2. Figure 2: FleetTrak™ network diagram The FleetTrak™ network is comprised of Base Stations, Repeaters, and Remote Stations. The MCC-545C can be programmed to operate as any of these three distinct station types. The FleetTrak™ network is used for position reporting in mobile applications (AVL), fixed site data collection (SCADA), and messaging. The FleetTrak™ network operates line-of-sight using groundwave and uses an LOS protocol for channel access. In an LOS network, there is always an RF connection path between adjacent stations, and stations transmit data whenever they have something to send. These transmissions use CSMA (carrier sense multiple access) to gain channel access and to prevent RF signal collisions. The range of communication by groundwave is primarily determined by diffraction around the curvature of the earth, atmospheric diffraction, and tropospheric propagation. These ranges are successfully extended by MCC from 50-100 miles through the use of robust protocols, sensitive receivers, and short packetized messages.

An internal lithium ion battery is used to maintain the internal real time clock and battery backed RAM. This battery operates the clock in a power down state for a period of approximately 6 months. This battery should be removed if the unit is stored for extended periods of time. In -03 or later versions of the units, the lithium ion battery has been replaced with a rechargeable nickel metal hydride battery. This battery is located at the rear of the unit with Velcro. (You have to open the rear lid to get access to it.) A short jumper is used to connect the battery to the processor board. This jumper should be removed if the unit is stored for long periods of time (longer than 2 months). The battery must be connected before the unit will start operating. 3.4 Transceiver The transceiver assembly contains a receiver, transmit and receive frequency synthesizers, and a modulator. The MCC-545C receiver and modulator support 9.6 kbps Gaussian Minimum Shift Keying (GMSK). GMSK Receiver • Input bandpass filter (37-50 MHz ) • RF amplifier (17 dB) • Low pass image filter (Fc=50 MHz) • Mixer • IF amplifiers and filters (10.7 MHz) • Noise blanker • Mixer, 2nd IF filter and amplifier (100 kHz), and RSSI circuit • Phase lock loop frequency discriminator • GMSK bit detector and clock generator Synthesizer (1st and 2nd local oscillator and transmit oscillator) • Reference Oscillator (12.8 MHz +/- 2.5 PPM) • Tx phase lock loop (74-100 MHz output, 20 kHz steps) (86-92 MHz, 20 kHz steps in FCC ID: BIB54505003-01) • A divide by 2 circuit (37-50 MHz output, 10 kHz steps) (43-46 MHz, 10 kHz steps in FCC ID: BIB54505003-01)

All components are surface mounted. 3.5 Pre-Amp, Final Power Amp, and Power Control This board contains two low-level amplifiers that amplify the +13 dBm (10 mW) signal from the modulator to the 2 watts required by the final power amplifier. A special power switch is used to control the rise and fall times of the RF power output. A duty cycle limiter circuit limits the duty cycle of the power amplifier to 16%. A temperature sensor is also located on this board for monitoring the internal temperature of the MCC-545C. This temperature reading may be transmitted to the Host for maintenance purposes. The 100 watt power amplifier is mounted inside an aluminum enclosure to provide RF shielding between the low level phase lock loop synthesizers and the high power output. This board contains a T/R switch for half-duplex operation, a harmonic low pass filter, and a dual directional coupler for power level control. The coupler measures forward and reverse power. If the VSWR exceeds 3.0:1 the power amplifier automatically shuts down. The power amplifier’s parameters are also transmitted to the Host for maintenance purposes. A switching regulator power supply provides 5.7 volts for the processor and transceiver boards.

Switches: SW1 System Reset, Momentary 3.7 Memory Organization The MCC-545C has three types of memory: 3.7.1 Program Memory (PM) The Program memory is non-volatile Flash (512K x 16). It contains the MBNET200 image software, bootstrap, configuration, and application software. These programs are installed at the MCC facilities at the time of shipment. The information stored in the Program memory is referred to as “factory defaults”. 3.7.2 Parameter Memory (CPM) The Parameter memory is non-volatile Flash (512K x 16). It contains the configuration data for the unit such as the customer number, the serial number and ID of the MCC-545C, and the authorized FCC frequencies it may use. This information is normally programmed into the unit prior to shipment. The Script files are also stored in Parameter memory, either at the MCC facilities or on site. 3.7.3 Data Memory (RAM) The Data memory is volatile RAM (1024K x 8) and has battery backup. Date, time, executable programs, command parameters, and program dynamic data (messages, data, position, etc.) are all stored in RAM during normal operations. As an option, the Data memory may be expanded to 2048K x 8. During normal operation, the MCC-545C software uses the data and configuration parameters stored in RAM. If the data information in RAM is lost or corrupted, for whatever reason, the configuration parameters can be retrieved from Parameter memory. This ensures uninterrupted operation.

(Remove the rear panel to locate SW 1.) • The internal backup battery fails or is disconnected. (In -02 units, remove jumper JP1 while the external power is turned off to the unit. In -03 or later units, remove connector J1.) • The watchdog timer initiates a restart. The software will detect these events and will recopy the parameters and configuration values from Parameter memory back into RAM when operation is resumed. If the contents of Parameter memory become invalid the unit will revert to the factory defaults in Program memory. 3.8 Front Panel LEDs The two LEDs on the front panel provide the operator with a quick assessment of the unit’s operational status.

Antennas suitable for use with the MCC-545C are listed in the MCC-545C RF Energy Exposure Guide. It includes details on the human to antenna separation requirements for specific fixed and mobile antennas with various gains. Always disable the transmitter when working on the antenna and/or co-ax cable. 4.2 Equipment Installation The MCC-545C operates over a temperature range from -30°C to +60°C and is housed in a stainless steel enclosure that can be used in a wide range of applications. 4.2.1 Mobile Applications Mobile applications can include vehicles, aircraft, vessels, and locomotives. Each application may require a different type of antenna. For example, a 3' base-loaded ¼-wave whip is generally a good solution for vehicles. Low profile antennas, vertically polarized, are required for locomotives. 10' ¼-wave whips are generally used for vessels; these antennas should be designed for operation in maritime environments. Refer to the MCC-545C RF Energy Exposure Guide for more antenna information and means to limit RF exposure. MCC’s engineering services department can be contacted for specific recommendations. For vehicle installations, the MCC-545C may be mounted in any convenient location (e.g., in the trunk, under the seat, or in the engine compartment). Refer to Appendix E for a list of example equipment components required for an MCC-545C used in a typical mobile application.

These connections are used for both mobile and fixed site applications. Figure 11: MCC-545C cable connections 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, with a cable length that does not exceed 10 feet. If a longer cable is required use #14 AWG. MCC provides a standard 6-foot power cable with lugs for connecting to a 3/8" battery post. The power connector pins are shown in Figure 3.6:

OPERATIONS This chapter covers the basic operating procedures for the MCC-545C as it is used in the FleetTrak™ network. The MCC-545C is programmed through the use of Script Files that contain the specific system parameters for operating in various modes. A script file is loaded into the MCC-545C at the MCC facilities prior to shipment. Script files may also be loaded and/or modified at the customer’s site. (Refer to Section 4.2.7 and Appendix C for more information on Script Files.) The last section of this chapter provides a summary of all MCC-545C commands; printouts from frequently-used commands are included in Appendix A. It is assumed at this point that the appropriate script file has already been loaded into the unit, as part of the installation procedures outlined in Section 3.3, and that the unit is configured properly and operational within its network. This chapter describes the various commands that are available to the operator for modifying the station configuration parameters to accommodate specific applications, sending and receiving messages, and interfacing to peripheral devices for position reporting and data collection. 5.1 Getting Started 5.1.1 XTermW Terminal Emulator XTermW is a windows-based terminal emulation program supplied by MCC. It is designed for interfacing with a wide variety of MCC products. All commands, script files, etc., can be entered into the MCC-545C using XTermW. The last section in this chapter contains a list of all valid MCC-545C commands. XTermW can also be used to create log files of MCC-545C operations. Refer to the XTermW documentation supplied with the program. Whether using XTermW, another terminal emulator, or a hardware terminal, you must program the operator terminal to use the same

Refer to the last section of this chapter for a complete list of MCC-545C commands. 5.1.3 Role-Based Operations The role that the MCC-545C plays in a communications network determines how it should be configured. There are three basic roles that an MCC-545C can be used in, depending on the network type: • LOS Network consisting of Base and Repeater Stations, and Remote/Mobile units; Base Stations do not communicate with each other in this type of network. This is a typical FleetTrak™ network. • LOS Network consisting of one or more Master Stations and Remote Stations (either fixed position or mobile units); Master Stations can communicate with each other in this type of network. This is a typical DataNet network. • Meteor Burst network consisting of a single Master Station communicating with Remote Stations in fixed positions; Remote Stations do not communicate with each other in this type of network. This is a typical Meteor Burst network.

Type the command ID and press [ENTER] to display the unit ID number on the operator terminal. In some cases this number will be “locked” and cannot be changed in the field; you can type LOCK to determine if the ID is locked or not. Under some circumstances the ID may have to be changed on-site. It can only be done if the ID is not locked. In that event, this action must be coordinated with both MCC and your System Administrator. Failure to do so may 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. To change the ID, enter the following command: ID,nnnnn,mmmm{,aaaaa},INIT where:nnnnnn = unit ID mmmm = Master Station assignment aaaaa = Master select mode: PREF, AUTO, MULTI, or FIXED Obtain the proper Master Station assignment and select mode from your System Administrator. The MCC-545C will save this ID and will use it whenever the unit is powered up or reset. Mode Description PREF Unit connects to the mmmm Master Station for the NDOWN period (set with SNP command). After NDOWN period unit connects to the Master Station that it has received the most syncs from. In this mode the unit can communicate with only one Master at a time. AUTO Unit connects to the mmmm Master Station, if it is not successful it switches to another Master Station. It will stay with that Master Station as long as it can communicate with it. In this mode the unit can communicate with only one Master at a time. This is the standard mode for FleetTrak™ networks.

The Master Station then periodically broadcasts this date and time information to all Remotes for synchronizing their internal clocks. The date and time of day maintained in the MCC-520B Master Station is transmitted to all Remote Stations between the times of 00:10:00 and 00:50:00 of each day, time keeping all units in a network on the same time reference. If the time of day received at a Remote Station differs by more than two minutes from the internal Remote clock, the Remote will set its clock to the received time of day. To properly manage time, each Master Station and Remote Station must know how its own time zone relates to UTC and the system time. This relationship is established by relating its time zone to known reference points. UTC is always referenced to GMT; however, system time can be referenced to any desired time zone. The time zone offset is defined with the following command: TIME ZONE, UTC offset, local time offset Always set “UTC offset” to 0; the “local time offset” should be set to the Remote Station’s time zone offset (+/- TZ) from the Master Station time zone. 5.1.6 System Memory The MCC-545C is designed to operate unattended in a variety of environments where power may be applied continuously or intermittently. The goal is for the unit to continue to operate without loss of messages, data, or configuration, even if power is randomly turned on and off.
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A 48 © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. Therefore the software is designed to operate continuously, to save all operational information when power is off, and to resume operation from that point when power is restored. To support this design, the MCC-545C has three types of memory: 1. Program Memory (PM) 2. Random Access Memory (RAM) 3. Configuration Parameter (CPM) The PM is non-volatile flash memory that has been programmed with the MCC-545C’s operational software. This software contains the initial values of all operational parameters. The values are referred to as the “factory defaults” because they are programmed into the MCC-545C operating system software at the factory. The PM can only be modified by replacing the operating system using the flash download. (Consult XTermW manual to learn how to download a new flash into the PM.) 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 are stored 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, a small internal NiCad or Ni Metal Hydride battery (internal to the unit) 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 parameters that are stored in RAM. Unfortunately, there are always situations when the RAM data may be lost or corrupted due to total discharge of the battery, software crash or operator error. Since we do not want to lose our configuration data during these situations, we have a third type of memory. The third type of memory, CPM, is also nonvolatile flash memory and retains data even when power is removed. The MCC-545C retains a copy of all the programmed configuration parameters in CPM. The MCC-545C will write configuration parameters, that have been entered from the operator port, into CPM when the SAVE command is entered. Only values that have changed are written into CPM. Whenever the unit radio ID is changed the MCC-545C will automatically SAVE the configuration. A validation checksum

Do Not Distribute. 5.2.1 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. Parameters or operational states set by these commands are retained and will determine the way in which the MCC-545C will interact with other equipment at the site and with the communications network. Most configuration parameters can be viewed with the CONFIG, ASSIGN, SNP, and CR10X commands. You should use these commands to verify that the configuration is correct. If it is not correct, use the appropriate command(s) to correct the configuration, and then enter the SAVE command to write the configuration parameters into the Configuration Parameter Memory (CPM) for non-volatile storage. The software normally executes using the data and parameters stored in RAM. When the unit is turned off, or power is disconnected, the RAM information will be maintained by battery backup. When main power is restored the unit continues operation from RAM. When this happens, you will see the following message on the Operator Port. (See Section 3.3 for details.) POWER SHUTDOWN/FAIL OCCURRED POWER HAS BEEN RESTORED... RESUMING OPERATION The RAM contents will be lost under the following conditions: • The boot command is issued. • The Reset button (SW1) is pressed. • The internal battery backup is disconnected. • The internal battery fails or is discharged. • The software crashes and restarts. The software will detect these events and will then recopy the configuration values from CPM back into RAM when operation is resumed. The software will revert to the factory settings contained in the PM if the contents of the CPM become invalid.

For example, assume you accidentally set the protocol for the operator port to MSC. If you do not have the ability to interface using MSC protocol you will immediately lose contact with the 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 (SW1). This will reboot and restore the CPM 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 your 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 MSC protocol. The Reset button now reboots to MSC and there is no easy way back to the factory default settings. You will need an MSC capability to command a change back to ASCII. 5.2.2 Setting frequencies The MCC-545C is programmed at the factory with the authorized frequencies to be used in your network. These frequencies are stored in Parameter memory and cannot be changed. You can display TX and RX frequencies by entering the following command: FREQUENCIES This shows you the active or “primary” TX and RX frequency pair, plus up to 9 additional frequency pairs for channels that may be programmed at the factory.

The time-to-live parameter input is truncated to a 10-minute boun¬da¬ry. If you enter 60 through 69, the TTL for the next message will be 60 minutes. A resultant value of 0 (parameter range 0 – 9) means the message will never time out. TTR – Time-to-retransmit in minutes (default is 30 minutes); i.e., the message is retransmitted if it has not reached its destination within this time frame. NUP – Neighbor-up threshold (default is 2 acquisitions); the number of times a Station must hear from another Station within a one minute time interval before it becomes a neighbor. NDOWN,xx,yy – Neighbor-down threshold in “xx” minutes (default is 120 minutes), and “yy” is the number of times a Station attempts to communicate with a neighbor before attempting to talk to another Station; if there is no communication with a neighboring Station within the set time, the route to that neighbor is ignored. Setting NDOWN to 0 maintains the routing to the neighbor indefinitely. RDOWN – Remote-down threshold in minutes (default is 2 minutes); if there is no communication with a Remote Station within the set time, 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 is allowed to send to another Station without an end-to-end acknowledgment. CONNP (Master Station operation only) – Connectivity message precedence (default is 1 precedence); information on changes in the connectivity table is given highest precedence (automatic feature). ETEAP – End-to-end ACK message precedence (default is 2 precedence); the acknowledgment of a message when it reaches its final destination is given highest precedence. HTO – History file timeout in minutes (default is 5 minutes); maintains information for duplicate filtering.

Do Not Distribute. 59 TEXTL (Master Station operation only) – Text message packet size in segments (default is 32 segments). FLOODP (Master Station operation only) – Partial “flooding” precedence level (default is A precedence). Messages of this precedence level and above are transmitted over all routes of minimum length; messages below this precedence are not sent over all minimum length routes, but are sent only over the routes where the shortest transmit queues exist. MBHOP – meteor burst link hop weight (default is 1 hop). Defines the number of network hops to associate with a meteor burst Master Station link when determining the minimum path to use in routing a message. MBHOP should be set high enough to prevent a meteor burst Master Station link to be chosen over a line-of-sight Remote to Remote link in a network that is predominantly line-of-sight. INF (Master Station operation only) – Infinity hop count (default is 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. RELAY (Master Station operation only) – Relay function specification (default is ON). Specifies whether the MCC-545C should act like a Remote Station in terms of relay functionality (i.e., does not share connectivity table with other Master Stations). 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 of data reports generated asynchronously by the equipment itself. Typically, it should be lower than operator entered messages and commands. Message Accountability SNP,TTL Message time-to-live SNP,TTR Message time-to-retry SNP,TEXTL Message packet size
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A 60 © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. Message accountability guarantees that text messages get delivered to their proper destinations within an allotted time. Data reports, position reports, and remote commands/responses donot get this guarantee. They get only one chance to get through the network. Networks can have units go offline for various reasons; local noise can interfere with RF links, congestion can slow throughput to a crawl, RF link bit errors can cause segments of a message to get lost, etc. The more complex a network is, the more chances there are to be problems. Messages entered at each source unit specify a time-to-live (TTL); this time is the maximum time to attempt to deliver it. If it is not delivered in this time, the operator at the source unit is informed so something can be done about it. The time-to-retry (TTR) is the number of minutes between attempts to deliver the message. Once a message is sent, it goes through the network one hop at a time and can get blocked at some point if the connectivity changes suddenly. The retry attempts are separated to allow network changes to settle out and establish alternate routes. When a message is received by a destination, an end-to-end-acknowledgement (ETE) is sent from the destination back to the source to stop any more retries and let the operator know the message was received. The maximum message size is determined by the text length (TEXTL) setting. A message packet can consist of up to 3570 characters and is further subdivided into segments. Each message is uniquely identified so it can be tracked through the network and the ETE can be sent for each individual message. The message ID consists of the originator ID (16 bits) and message serial number (8 bits). Serial numbers range from 1 to 255 and are assigned in round-robin order. Each message is then split into 14-byte segments which are in sequence from 0 to 255. The segments allow the message to be transmitted a little at a time over short meteor bursts. The segment sequence numbers are used by the RF link software to identify which ones are acknowledged and to indicate where to resume on each burst. The first segment (sequence number 0) is the message header and contains all the network overhead (originator ID, message serial number, priority, I/O port entered on, message type, number of destinations, number of segments, time to live, retry count, multi-packet message serial number,

Do Not Distribute. 61 packet sequence number, total number of packets and first destination ID code). If the message has only one destination, segment 1 is the start of the actual text. If there are multiple destinations, segment(s) 1, . . . n contain the remaining destination codes, 7 destination codes per segment. The text starts on the next segment after the last destination code. Network Connectivity Tables SNP,NUP Number of receptions for neighbor-up SNP,NDOWN Number of minutes for Master neighbor down SNP,RDOWN Number of minutes for Remote neighbor down Network connectivity tables are automatically created and updated each time a Master detects a new neighbor unit or times out an existing unit. The NUP parameter gives the number of transmissions that must be received in one minute to declare a new neighbor. The NDOWN parameter gives the number of minutes with no receptions to time out a Master neighbor. The 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). The NDOWN parameter can also be set for the number of times a Station attempts to communicate with a neighbor before attempting to talk to another Station. Congestion Control SNP,OTL Outstanding text limit The OTL parameter specifies the maximum number of messages that will be transmitted while waiting for ETEs. Limiting messages, as cars are limited to entering the freeway at rush hour, tends to reduce congestion and memory buffer usage in the network and reduce the number of retries that happen as a result. Sending messages one at a time does not take advantage of the overlap caused by the ETE needing to come back through the network and does not take advantage of an occasional large burst that can significantly improve throughput. Network Control Messages SNP,CONNP Priority for connectivity messages SNP,ETEAP Priority for end-to-end-ack messages SNP,FLOODP Priority level to initiate “flood-routing” SNP,DATAP Priority for data reports

The priority of network control messages should be set higher than the data traffic. This setting makes sense if you realize that messages can not get delivered as fast if the network connectivity is incorrect. Certain applications may have reasons for altering these values but any revision to the default priority scheme should be implemented carefully. History Timeout SNP,HTO History timeout for duplicate filtering As each message is received by a unit, the originator ID and message serial number are retained in a history table. The HTO parameter specifies how long to retain each entry. Each received message ID is compared to this table and if the message was previously received and has not timed out, it is considered a duplicate message. The ETE is sent to the originator if it is a text message type but the duplicates are not output to the I/O ports. Duplicates happen due to network connectivity changes and retries. Hop Count SNP,INF Infinity hop count The INF parameter specifies the maximum width of a network in hops + 1. If this parameter is set lower that the actual network width, units will be declared offline when they are not. If the number is set too high, extra connectivity packets are exchanged when a unit goes offline and the system looks for alternate routes. SNP,MBHOP Meteor burst link hop weight The MBHOP parameter defines the number of network hops to associate with a meteor burst Master Station link when determining the minimum path to use in routing a message. This parameter should be set high enough to prevent a meteor burst Master Station link to be picked over a line-of-sight Remote to Remote link in a generally line-of-sight network. Message Relay SNP,RELAY Enable/disable Master’s ability to relay messages for other destinations

Do Not Distribute. 63 The MCC-545C, when configured as a Master Station, reports all of its neighbor connectivity to its neighbors when SNP,RELAY is set to ON. If it is set to OFF, it does 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. Selecting the Burst Monitor The MCC-545C has a unique meteor burst monitoring capability that allows monitoring the number 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 two or three lines of printout for every burst. This could conceivably create hundreds of pages of printout a day in a network environment. The first parameter is the duration character count limit. Only meteors lasting long enough to deliver “d” characters will be monitored. The second parameter 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, to limit the printout, but still receive some maintenance benefit from the monitor, enter: MON,500,100 This will limit the printout to meteors that have a duration character count greater than 500, or a received character count greater than 100. These parameters may be adjusted as desired. The command MONOFF turns off the burst monitor. 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 statistic 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 5.3 Sending and Receiving Messages The MCC-545C is a packet data radio and therefore enables an operator to send and receive messages to all units within the FleetTrak™ network. The messages may be entered from an operator terminal that is connected to the OPERATOR PORT of the MCC-545C. There are three basic message types: 1. Free-form text messages 2. Canned messages 3. Commands The general format for all messages is shown below: MESSAGE,p,dest1,dest2,...dest n where: p = any priority level from A (highest) to Z (lowest). dest n = numerical ID of the station(s) to which the message will be routed. The message text is then 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. Figure 14 depicts the general flow of messages within the MCC-545C software and the various commands associated with each step in the process.

The appropriate script file must be loaded into the MCC-545C that allows it to interface to the protocol used by a particular GPS. The NMEA 0183 Version 2.0 protocol is used in this section for descriptive purposes only. Please consult MCC regarding script files for other protocols.
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A 74 © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. The MCC-545C will accept either a TTL or an RS-232 input from a GPS receiver. The internal GPS uses the TTL interface and its output is internally routed to the processor board assembly. If an external GPS is used it may be connected to either the AUX port or the Data port using the RS-232 interface. 5.4.1 Position Reporting Commands The following commands are normally in a script file and are used for configuring the MCC-545C for position reporting. Command Description ASSIGN,POS,p,GPS Port selection for transmission of GPS data. p = Selects the desired port: 2 = External AUX, RS-232 3 = Internal TTL SETBAUD,POS,4800,N,8,1 Set up parameters for the selected port. For example: 4800 = Baud rate N = Parity 8 = Data Bits 1 = Stop Bit POS,nn,TEXT,NMEA nn = Transmit interval in seconds of a position report to the system host. TEXT = Binary Text NEMA = Protocol type Note: Each time a report is transmitted to the Host it may also be sent to one of the local ports. POS,LOCAL,nn nn = The time interval in seconds between reports sent to a local port. Note: This feature is used when more frequent position reports are desired on a local operator terminal than are being sent to the Host. POSRPT,ON ON = Used to display position reports from other remotes on a local operator terminal. OFF = Disable

Do Not Distribute. 75 5.4.2 Differential GPS MBNET200 (ELOS protocol) may be used to broadcast differential correction data to all Remote Stations in the network. This eliminates the need for having a differential GPS receiver at each MCC-545C mobile unit. Differential beacon receivers are installed at base or repeater stations only. The base stations then transmit the RTCM correction data at periodic intervals to all repeaters and mobiles. The ASSIGN and SETBAUD commands are used to configure the base stations to use a beacon receiver. Command Description ASSIGN,POS,p,RTCM,nn Port selection for transmission of RTCM data. P = Port number, normally AUX port (2) is used. Nn = The interval, in seconds, that the RTCM error correction data is transmitted. A value of 20 seconds provides reasonable accuracy. SETBAUD,POS,4800,N,8,1 Set up parameters for the selected port. For example: 4800 = Baud rate N = Parity 8 = Data Bits 1 = Stop Bit A remote station will automatically receive and process the RTCM correction data. No other configuration commands are required. 5.4.3 GPS Report Formats There are two position report formats used. The POS format is the basic report and has latitude, longitude, speed, heading and altitude. The POSS format includes all the information above but also has a 16-bit status word and an 8-bit code for appending canned messages. An example of each type of format is shown in Figure 4.2.

Figure 15: Position report formats The Status bit field is application dependent and is normally defined by the user. For non-maritime applications speed is converted from knots to MPH on the operator’s display. The GPS status bits define if the GPS receiver is locked and the accuracy of the data. V0 GPS not locked; position data is not valid.

V2 accuracy will normally be ±2 meters and is dependent on the RTCM broadcast rate and the distance between the mobile and the nearest base station. 5.4.4 GPS Receiver Setup The setup procedure for a GPS receiver is generally different for each manufacturer’s type. Connect a laptop or PC to the GPS receiver for entering the desired sentences and update interval. A NMEA type GPS must be configured as follows: Type of sentence Update interval Status GPRMC 1 second Required GPGGA 1 second Required GPVTG 1 second Optional The TRACE command may be used to verify correct GPS operation: TRACE,ON,GPS All characters received will be displayed on the Operator Port, including sentence types. Verification that the position report is being transmitted at the desired POS,nn interval may also be observed. To disable the display output, enter: TRACE,OFF 5.4.5 Position Reporting in Subnets The SUBNET command assigns a subnet code number from 1-255. The code number is maintained in the locked configuration parameter list along with the serial number, customer number and frequency table. The command formats are: SUBNET Display current subnet setting SUBNET,OFF Turn off the subnet number (must be unlocked) SUBNET,nnn Define a subnet number (must be unlocked)

The connection will remain open for as long as characters are being received or the connection times-out, whichever occurs first. Once the connection times-out it must be reestablished. If the connect string is unknown, the command ANY will open the connection for any string of characters. Connect Response A connect response string may be enabled so that the peripheral device initiating the message will receive confirmation that the connection has been made. If the connect response string is turned OFF then no response will be sent when the connection is made. Message Management A message may be as long as 3,500 characters. Each message is assigned a sequence number and is broken up into a number of packets. A message header is inserted into each message ahead of the first data character. $DIR,p,m,s,n where: p = the assigned port to which the message is directed. m = the message sequence number from 1-2554 s = the packet sequence number in a multi-packet message n = total number of packets in a message A message will be appended with either a terminator character or a maximum character count. The message will be terminated by either one of these characters or the “time-out” whichever occurs first. Shorter messages are normally contained in a single packet with the s,n parameters set for 1,1. Longer messages will have several packets contained within the same message number “m”. The “s” parameter for each packet will be incremented but the “n” parameter will be set to 0. The true “n” value is only transmitted with the last packet in the message. For example, for a 3 packet message the s,n and m parameters will be as follows:
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A 84 © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. $DIR, p, m, s, n Packet 1 1 1 0 Packet 2 1 2 0 Packet 3 1 3 3 Messages may be transmitted from one to four destinations. When a DIRECT message is received at the destination MCC-545C, it will be routed to the assigned port(s) (Operator, Data or AUX). There are two types of connections that may be used: point-to-point and multi-point-to-single-point. Point-to-Point In the point-to-point mode the destination MCC-545C must also be pre-programmed in the DIRECT mode. When the message is received at the destinations, the $DIR,p,m,s,n header will be removed from the message and the message will be routed to the same port that was used at the source. That is, messages that were originated on Port 1 must also be routed to Port 1 at the destination. The destination unit can respond with its own character stream back to the source. This provides a direct point-to-point, bi-directional channel between the two stations. The embedded ETE acknowledgement in the ELOS protocol may be used for ensuring message delivery. Multi-Point-to-Single-Point Many remotes can be set up to operate in the DIRECT mode, all routing their data to a common destination (base station or Host). The destination station does not have to be pre-programmed in the DIRECT mode as in the point-to-point case. The destination station will treat the message as it would for any other text message, using one of the many available port protocols. The message header, $DIR,p,m,s,n, is retained with the message so that the destination station will know how to format a return message to the source station. In this manner, the Host can send response packets to all sources by appropriately formatting the message header.

DIRECT, p, PACKET TIMEOUT, decimal-timeout-ticks Defines the timeout period in 1/16 second clock increments that marks the end of a packet. After each character of the packet is received the timer is reset. After the last character has been received and the timeout passed, the characters received will be placed in a message and queued for transmission. DIRECT, p, PACKET TERMINATOR, OFF Disables packet termination using a specified character code. DIRECT, p, PACKET TERMINATOR, decimal-char-code Enables packet termination when the given character code is received. For example, using a carriage return to terminate each packet will transmit each line of input as a separate message. The decimal code for carriage return is 13. The decimal code for linefeed is 10. DIRECT, p, MAX PACKET, length

As characters are received they are filled into a buffer and when the maximum size is reached a new message is transmitted. The longest message that can be used by the MCC-545C is 3,500 characters. DIRECT, p, ETE, ON Defines the “reliable” type of message delivery. The source unit will retain each transmitted message and periodically retry them until the destination unit receives them and sends an end-to-end-acknowledgement for each message. It is possible for messages to be delivered out of sequence when a retry has occurred causing duplicate messages. These duplicate messages will be filtered out. DIRECT, p, ETE, OFF Disables the “reliable” type of message delivery. The source unit will not retain each transmitted message for retries. Each message will be deleted as soon as transmitted. It will be the responsibility of any receiving equipment to manage the message reliability. If any message gets lost in the RF network, then all characters in that message will be lost. 5.5.4 Defining Data Relays The ambient noise conditions at a remote station site may sometimes be excessive and a poor communication path to the Master Station will result particularly if the remote station is operating in a meteor burst mode. To overcome this problem, another MCC-545C may be placed in a nearby quiet location and used as relay station between the MCC-545C at the noisy site and its master station. When used as a relay, the MCC-545C will concentrate the data reports it receives from one or more neighboring remote sites and forwards the data to the Master Station. When used in the relay mode, the MCC-545C must be defined as a Master Station. The relay will 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 sixteen GROUP reports. These reports can be in any combination; i.e., four groups from each of four Remote units, one group from each of sixteen Remote units or any

Substitution tables must be established in both the relay unit and also at the Master Station to manage the relay function. When a designated GROUP report is received at the relay, it will substitute its own ID and group number in the report as defined in its substitution table and forward the data to a MCC-520B Master Station using the MCC-550C RF format rather than the standard MCC-545C message format. When the relayed data is received at the MCC-520B it reconstructs the original data report 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_group where: relay_id = relay unit’s ID relay_group = data group report number at the relay remote_id = originating Remote unit’s ID remote_group = data group report number at the originating Remote unit 5.5.5 I/O Port PASSTHRU The PASSTHRU command allows a bi-directional connection to be made between the different I/O ports of the MCC-545C. This will allow the operator to configure one port to be connected to another port in a direct ASCII mode where any characters coming in on one port will go out on the other port, and vise-versa. For example: the command PASSTHRU,1,2 allows characters entered on port 1 to go out port 2, and characters received on port 2 will go out port 1. There can be from 0 to 2 different pass-through connections defined at any time. All ports given in a pass-through connection must be assigned to some protocol and baud rate before entering the PASSTHRU command. An error will be displayed if they are not.
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. 89 Data coming in from a passed-through port will not be passed to the assigned protocol driver and will be sent out the “other” port of the connection. The connection can be turned off by entering PASSTHRU,OFF,n where “n” is either port in the connection. In addition either port in a pass-through connection can output the string PASSTHRU,OFF to close its own connection. The first method can be used from the operator port to close a connection of other ports. The second method is used by the operator port if it is one of the ports in the pass-through connection. If port 1 is assigned to a CR10X driver, and port 0 is the operator port, then the command PASSTHRU,0,1 allows the operator port to be connected directly to the CR10X. One can then use XTermW or PC208 to talk to the CR10X via the operator port without re-connecting cables. 5.5.6 Internal Sensor Values The new MCC-545C -03 and later radios have the capability to read a number of internal sensor values. These include: • Internal temperature of the MCC-545C unit • Internal rechargeable battery level • External battery levels (loaded and unloaded) These sensor values can be read using the EVENT command – refer to Section 4.6.8 for details on how to program the MCC-545C to read these values. 5.5.7 Generic Data Logger The MCC-545 family of RF Modems includes a set of device drivers for its serial ports. These have been customized for various external devices, depending on the device requirements. The SDATA command allows a simple text-based interface to send data groups to the MCC-545C for transmission to the master. Any customer who can configure their data report to meet this format can interface their data logger with no change in the MCC-545C software. From 1 to 16 groups can be input, and there can be from 1 to 16 sensors per group. Each sensor data value is formatted into
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A 90 © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. a 16-bit binary value for transmission, then converted to engineering units by the Data Center or Host software. Some date loggers have a complex and non-configurable interface protocol, and cannot meet any of the currently implemented protocols, but they can output data reports on a serial port as if it were connected to a line printer. The GENERIC data logger driver has been created for this type of interface. Some things can be setup by user commands to configure the report parsing, within a limited set of constraints, and allow the MCC-545C to create SDATA type messages from the ASCII text reports. The following sections describe what can be done to adapt the MCC-545C to a variety of report formats. Typical Report Formats A typical report printed by a data logger has one line, or a set of lines for each report. There are usually two types, single-line reports, and multiple-line reports. An example of each type would be as shown below: Single line report examples: 123.4 19.8 33 99 -1089.45 ...<cr><lf> or 10/14/02 09:15:00 +123.4 +19.8 +33 +99 -1089.45 ...<cr><lf> Note that the report ends with carriage return and linefeed characters, and may or may not display a date and/or time. The data fields are usually separated by blanks, and the data values may or may not contain a sign or decimal point. The line is usually output by the data logger as the report is placed into the devices' memory in real-time. There is no provision for error checking, but if the serial port cable is wired correctly with shielding, etc., it may be reliable enough. Multiple line report examples: No Time Tag With Time Tag With Sensor Labels 123.4<cr><lf> 10/14/02 09:15:00<cr><lf> Date/Time: 10/14/02 09:15:00<cr><lf> 19.8<cr><lf> +123.4<cr><lf> AC Voltage +123.4<cr><lf>

This can happen if the data logger “echoes” the polling command. The generic device driver will “see” the echoed command as part of the data report response. Setup and Configuration The MCC-545C generic data logger driver can configure the following: • Report type (single-line, multi-line) • Group ID Number (Auto generated, Location in report, Fixed) • Date (Auto generated, Location in report, Format of date characters) • Time (Auto generated, Location in report, format of time characters) • Sensor Values (Auto free-format, Location in report) • Poll command definition • Start-of-report definition • Remote Commands Each operator command begins with the command name and port number as shown in the following command. Example: GENERIC,1,TYPE,AUTO. Selecting the Generic Protocol for a Port The ASSIGN command is used to define the device driver to use on a port. As an example, the command ASSIGN,DTA,1,GENERIC,5 will assign the DTA function to use port 1 (the DATA port), and run the GENERIC data logger device driver with a 5 second timeout. Use the SETBAUD,DTA,9600 command to specify a baud rate for the port. Any port (0-3) can be used, and multiple ports can select the generic device driver at the same time. Port 0 is usually reserved for a operator terminal, and port 3 is an internal GPS port. That means ports 1 and 2 are open for external devices.

Viewing the generic device driver setup Enter the GENERIC command with no parameters to display the current setup for all active ports. The following example response shows a typical setup with only port 2 set up for generic operation. +generic 12/11/01 10:54:32 Rpt Group................... Date......... Time......... Sensor.......

The Group section has 5 fields: Type, Number, Line number, Start column, End column, and Scale factor. This line shows the group is fixed at group number 2. The Date, Time and Sensor sections each have 4 fields: Type, Line number, Start column, End column. The date is on line 1 between columns 10 and 16. The time is on line 1 between columns 18 and 25. The first sensor value is on line 2 between columns 22 and 23, and the remaining lines of the report will each contain 1 sensor value between columns 22 and 23. The sensor values can be scaled by the multiplying factor shown in the Scale column. (The default scale is “1”.) The line following the port 2 line shows additional options for that port. Shown here are the start-of-report string, the date format, and the time format. Only options selected will be shown on this line. All of the settings in this generic driver table are saved in the non-volatile memory of the MCC-545C. Report Type: GENERIC,P,TYPE,{AUTO,LINE,OFF} This command selects whether the report is in a single-line format or multiple-line format. AUTO specifies single-line with free format, and LINE specifies the multiple-line format. The OFF option is provided to turn off a previously set-up port. Reports are parsed from sets (bursts) of characters read into a 1024 byte buffer. The end of the data set will be signaled by a timeout period with no more characters being received. The timeout is taken from the ASSIGN

When each set is finished being processed, the input buffer is cleared to wait for the next set of characters. AUTO Format For the simplest AUTO report type, with no group number, date or time stamp, each line will be parsed from left to right using blanks and commas as delimiters between data values. The carriage return and line feed characters are also ignored. The first group report will take up to 16 data values, then the next 16 go into group 2, the next 16 into group 3, and so on until the last character has been reached. For example, consider the following set of characters: 1 2 3 4 5 6 7 8 9 10<cr><lf> 11 12 13 14 15 16 17 18 19 20<cr><lf> 21 22 23 24 25 26 27 28<cr><lf>...timeout This character set will create two groups where the values 1-16 will go into group 1, and the values 17-28 will go into group 2. Each report will be time and date stamped using the current time of the MCC-545C. Up to 256 data values can be parsed into 16 groups using this format as long as the total number of characters in each set does not exceed the buffer size (including all delimiters). An Example of an AUTO format with a date and time stamp is: 10/15/01 12:00:00<cr><lf> 1 2 3 4 5 6 7 8 9 10<cr><lf> 11 12 13 14 15 16 17 18 19 20<cr><lf> 21 22 23 24 25 26 27 28<cr><lf>...timeout

Another example: 10/15/01 12:00:00 1 2 3 4 5 6 7<cr><lf> 8 9 10 11 12 13 14 15 16 17<cr><lf> 18 19 20 21 22 23 24 25 26 27<cr><lf> 28<cr><lf>...timeout For these two formats with date and time above, the port should be setup for an AUTO report type, then select a date and time option that locates the date and time fields on line 1. Use the sensor setup command to indicate that t he 1st sensor is located either on line 2 as in the 1st example or on line 1 as in the second example. The AUTO formatting will use the first two “fields” found as the date and time, then use the remaining fields as the sensor data. MULTI-LINE Format For the LINE (multi-line) report type, the first “line” includes all the bytes from the beginning of the buffer to the first carriage return. Any line feed characters are ignored. The second line is all the bytes from one past the carriage return to the next carriage return and so forth to the end of the set of characters. The report ends with the last character received prior to the timeout period with no more bytes being received. This example shows that each line holds only one sensor value. Reports with both labels and data that have multiple values per line are not yet supported by the generic driver, but it is possible to report multiple sensors per line when there are no line labels present on each line. One example of a multi-line report from the AANDERAA 3660 data logger is shown below: Date/Time: 1.12.11 18:57:50 00 Battery Voltage 12.7 Volt 01 Reference 699 02 Wind speed 79.4 m/s 03 Wind gust 79.4 m/s 04 Wind direction 359.6 Deg.M 05 Air temperature 48.8 Deg.C 06 Relative humidity 101.6 % RH 07 Air pressure (QNH) 1089.6 hPa 08 Visibility 3002.9 m 09 Sunshine duration 1023.0 min

The time is also on line 1 in columns 21-28. Sensor data then starts on line 2 and repeats on subsequent lines in columns 25-30. The label fields are ignored. Group Number: GENERIC, P, GROUP, AUTO GENERIC, P, GROUP, LINE, line number, start, end GENERIC, P, GROUP, FIXED, line number The AUTO group numbering will start at group number 1 and increment by 1 for each 16 sensor values. The LINE option allows the group number to be within the data at the given line number and between the given start and end column numbers. The FIXED option will use the “line number” parameter as the first group number then increment by 1 for each 16 sensor values. Date: GENERIC, P, DATE, AUTO GENERIC, P, DATE, LINE, line number, start, end,{FORMAT} The AUTO date option will use the MCC-545C internal Date. The LINE option allows the date to be within the data at the given line number and between the given start and end column numbers. The FORMAT is optional, and shows a “template” of the date format. It can be “mm/dd/yy”, “yy/mm/dd”, “mmddyy”, “yymmdd”. If the format is not given it will default to the “mm/dd/yy” format. Time: GENERIC, P, TIME, AUTO GENERIC, P, TIME, LINE, line number, start, end,{FORMAT} The AUTO time option will use the MCC-545C internal time. The LINE option allows the time to be within the data at the given line number and between the given start and end column numbers. The FORMAT is optional, and shows a “template” of the time format. It can be “hh:mm:ss”, “hh:mm”, “hhmmss”, “hhmm”. If the format is not given it will default to the “hh:mm:ss” format. The MCC-545C SDATA reports are only time-tagged with month-day-hour-minute. Year and seconds are not transmitted.

Sensor Values: GENERIC, P, SENSOR, AUTO GENERIC, P, SENSOR, AUTO, line number, start GENERIC, P, SENSOR, LINE, line number, start, end In AUTO mode, sensor values are delimited by blanks or commas and there may be several per line. If the line number parameter is not given (example 1 above) then data is assumed to start on the first line of the report. If the line number is given, data can start on other than the first line. In addition, if the “start” parameter is given, data can begin in a column other than the first column. For example you may have a report such as the following: 10/14/02 09:15:00 +123.4 +19.8 +33 +99 -1089.45...<cr><lf> Notice it has a date, time, then data values on the same line. In this case you would use a GROUP,P,SENSOR,AUTO,1,18 command to locate the start of the sensor data, and use the AUTO method of locating the rest of the data. In LINE mode, sensor values will start on the given line number and start-end columns, then will repeat, either in free format, or one value per line, depending on the report type. Polling: GENERIC, P, POLL, poll string, interval The polling feature can be used for data loggers that do not print a data report unsolicited, but require some command string to be sent to request the next report. The poll string can be any printable ASCII characters up to 20 bytes in length. The “interval” parameter is given in decimal and is the number of seconds between outputting the poll string. If a poll is output, the response string from the data logger will be parsed in the same manner as when there is no poll string required. If the data logger echoes the poll string, this will look like part of the report and must be accounted for in the setup. To handle data loggers that need to wake up from a low-power mode, the poll string will be preceded by a carriage return and line feed, and the poll string will be followed by another carriage return and line feed. Polling using binary (non-printable-ASCII) characters is not yet supported. Start of Report: GENERIC, P, REPORT, Report String
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. 97 The report string allows the definition a fixed string of printable ASCII characters that is at the beginning of each new set of report characters. This is useful for ignoring bursts of non-report text. Each report is started with the report string and ends with the timeout parameter. If the cable between the data logger and MCC-545C is connected part way through the output of one report, and the report string text is “missed”, then a partial report will not be created. Remote Commands: GENERIC, P, COMMAND, command string Some support for remotely commanding and configuring a generic data logger is provided using this command format. If the data logger can accept commands as a single line of text (no embedded <cr><lf>) without having to be locally present at the data logger to type keys into a menu, then this capability may be just the ticket. When a remote command is received by the MCC-545C, it will output the Command String bytes to the data logger preceded and followed by a carriage return and line feed. The response text, up to 1024 bytes, will be captured and returned to the originating modem as a remote command response message.

Discrete and analog inputs can be monitored by the event program to detect “events” which then perform a defined “action.” Actions may include the controlling of discrete output signals, incrementing counters, setting timers, transmission of canned messages, and issuance of various reports. This means that customers are somewhat independent of factory reprogramming from MCC and that MCC-545C behavior can be readily modified in the field. It also means that operators now have limited power to make the MCC-545C react to various field-programmable conditions. The operator sets up the event program when installing the MCC-545C or during maintenance and operation. Because the event program is implemented via operator commands, it can be entered not only at a local maintenance console, but also via the remote command capability. The event programs are stored within a non-volatile table in the MCC-545C battery-backed-up RAM. They are not lost due to external power failure. When the external power is restored, they will be enabled to respond to events again. Refer to Figure 16 for a block diagram of event programming inputs and outputs. Programming is usually done by creating a “script file” of the required event commands, and loading these into the MCC-545C using XTermW or any other terminal emulator software. Several input/output lines are available directly from the processor card of the MCC-545C modems. These differ between the A, B, and C variations of the MCC-545. In addition, an optional I/O expander card (XIO) uses 3 lines to implement a high-speed serial link for accessing the signals of the expander card.

Do Not Distribute. 99 Figure 16: Event programming block diagram 5.6.1 Event Programming Overview Event programs are composed of signal test and action commands stored in a non-volatile event table. The MCC-545A stores the event table in battery-backed-up-RAM. The MCC-545B and MCC-545C store the event table in FLASH memory. The operator enters these event commands into the MCC-545C. The MCC-545C scans the event table at power-up/reset, and then at every 1/16 second clock interval. It looks for the occurrence of defined events. When a defined event occurs, the MCC-545C invokes the corresponding action commands. The capability includes: • Testing discrete input lines • Setting or clearing a discrete output line • Testing Analog input values • Transmitting brief text messages • Execute a local command of up to 40 characters • Transmitting vehicle position reports • Transmitting marker drop reports MCC-545 Rf Modem EVENT SCRIPTFILE TEXT EDITORXIO$HTTEXTMESSAGES REMOTECOMMANDSDISCRETEINPUTSDISCRETEOUTPUTSANALOGINPUTSDISCRETEINPUTSDISCRETEOUTPUTSANALOGINPUTSRF LINKSERIALPORTMCLKMDIRMSETPOS TEXTMSGSDATA

In addition other status bits can be set or cleared individually. Up to 16 data report groups can be defined for SDATA formatted data report generation. The MCC-545C event monitor reads discrete and analog inputs and evaluates them with respect to event definitions in the event table. It can look for discrete input signals going persistently high or low, and for analog signals persistently exceeding or under running thresholds. 5.6.2 Event Definition An “event” occurs when some input signal or timer changes its state. You can think of a state as being “on” or “off”, “1” or “0”, “true” or “false”. When the state changes, an “action” can then be taken. Once the signal has changed state and the action performed, it will not take further action until the state changes again to prevent a continuous string of actions. For example, if a switch is turned “on”, the lights come on and stay on. They don’t continually go on,on,on… Once the switch is turned off, the lights can go off, and then they are ready to be turned on again, etc. There are three classes of events: Reset, Immediate and Scanned. Scanned events subdivide into discrete I/O events and analog input events. These are defined in the following paragraphs.
545C Operations Manual 02/10/2012 Prerelease DCN 00001789-A © 2012 Meteorcomm LLC. All Rights Reserved. Proprietary and Confidential. Do Not Distribute. 101 Reset Event A reset event occurs only once when the MCC-545C powered up or reset, when the event monitor task is started for the first time, or is stopped - then restarted. It is a well-defined event that does not need to scan anything in order to determine whether or not a reset has occurred. It occurs once on each power up or monitor-start. There is also no corresponding end to this event. The logical end of this event would be power failure or shutdown, but either such event makes the MCC-545C unable to respond to anything. An action taken on a reset event command will remain as defined in the command until the MCC-545C is reset again or powered off, or until some other event changes the action. Stopping the event monitor will not clear the reset event definitions. Command Event An immediate action can be triggered by entering a local event command from any port, or by remote command sent over the RF link. This type of action does not get stored in the event table and will not be re-issued on power-up or restart. In this way, the operator has the ability to manually override or control conditions in the field. The event state is considered to be “true” as soon as the command is entered or received. Once the action is completed, the event state is set to “false” again. Scanned Event Scanned events are tested on a periodic basis by the monitor task. An input signal that would trigger a scanned event must be repeatedly tested to see if the signal persists at a trigger level before an event is started. A scanned event is started when a signal remains at (or above or below) the trigger level for a defined settling duration. When an event is detected by its input condition persisting at its high state for a settling duration, that event's associated action is triggered and the monitor task begins looking for the end of the event. The end of an event occurs when the event remains at a low state for a defined hold-off duration. After the hold-off duration with the input condition at its low state, the event is enabled to scan for the next event. For example, if an event is testing the battery voltage to be above 5.0 volts, the action will be triggered when the voltage is first detected to be at or above 5.0 volts for the entire settling period. When the voltage goes below 5.0 volts for the hold-off period, it will re-arm the event to trigger the next time the voltage goes to or above 5.0 volts. The event action is

Do Not Distribute. not triggered when the voltage crosses the 5.0 level in the downward direction, only the upward direction. If one wants to detect both voltage crossings, there should be two events defined, one to detect the positive change (ADCHI), and one to detect the negative change (ADCLOW). The settling and hold-off durations are programmable for each scanned event. They are specified in clock-tick counts where each tick is 62.5 milliseconds, or 1/16 second. Because these durations are programmable, scanned event hysteresis is fully controllable. Given the 62.5 millisecond sampling rate, events are limited to those that persist longer than 62.5 milliseconds but shorter than about an hour duration. Similarly, hold-off times between events must also persist longer than 62.5 milliseconds. Attempting to program events that are briefer than 62.5 milliseconds will prove unreliable. It is important to remember that a scanned event must change slow enough that the event monitor can sample the input line reliably. The external I/O expander (XIO) has its own processor to scan its event definition table. Its internal “clock-tick” will be set to one millisecond per increment. The MCC-545C will configure the XIO when event commands are processed from the script file. The XIO will monitor its own events and send changes to the MCC-545C using a serial interface. Discrete Event A discrete event is determined by whether or not a discrete input signal remains either high or low for the given settling duration. “high” or “low” is a part of the event definition set by the operator. The end of a discrete event occurs when the signal has persistently returned to its previous low or high state for the hold-off duration. For RS-232 signals, “high” is considered the ON state and “low” the OFF state. “high” is also known as SET; “low” as CLR. The high/low convention follows the voltage level of the input signal. For TTL signals, “high” is a +5 volt level, and “low” is zero volts. For the RS-232 modem-control signals, “high” is +10 volts and “low” in -10 volts. For the GPS input, a “high” is when the GPS is at “V1” or “V2” status, and “low” is when there is no GPS characters being received at the RS-232 port or when the GPS is at the “V0” status. The NET input is “high” when the RF modem is online to a Base or Repeater that is connected to a host system.

Do Not Distribute. 103 The NET “low” input indicates the RF modem is offline to a Base or Repeater. Analog Event An analog event is determined by whether or not an analog input signal remains above or below a threshold for the given settling duration. “Above” or “below” and the threshold level are also given in the event definition. The end of an analog event occurs when the signal has persistently returned to the non-event side of the threshold for the hold-off duration. 5.6.3 Action Definition An “action” can be assigned to each event defined in the event table. When the event condition is detected, the action is initiated. Available actions are defined in the following sections. Multiple actions are supported by defining multiple events that test the same input, but take different action, or multiple actions can be defined using a special “continue” event. The “continue” event does not test the input condition again, but will trigger the action when the event it is connected to detects the event. Any action can be forced on a timed basis by several methods. One method is to use the MCC-545C scheduler (SCHED command) to trigger the desired immediate action. For example, the UPDT action can be specified by the insertion of the EVENT,UPDT, group-number command into the MCC-545C scheduler to produce reports on a timed basis. See the SCHED command for this capability. Another example would be to pulse an output line by placing two commands in the scheduled event list that would first SET then CLR the signal. The duration of the pulse would be controlled by the offset value in the SCHED command. Yet another method is to use an event timer (counter) to facilitate scheduling of actions. Special timer registers are provided for this purpose, and will automatically count down from a non-zero value to zero at a rate of 1/16 seconds per count. An event command can monitor the timer register, and when it reaches zero, the action can be taken, and the timer reset to the next desired time count.

Do Not Distribute. 5.6.4 Programming in Real-Time Events are programmed via operator commands, one event per command line. It is a multi-step process. Because of this, each event being entered will be a fragment until all event definitions are complete. If the event monitor is allowed to execute a fragment of an event, strange and possibly adverse actions will occur. Therefore, the operator should stop the event monitor when adding events and actions to the event table. The event monitor task can be stopped and started by operator command. The best way to do this is to use a script file containing the stop ;l,m command, a command to delete all prior definitions, the desired event definitions, and a start command. Some examples are given below, following these, a detailed description of each event command and action is given. Example 1: A Scanned Event - Vehicle Tip-Over Detection Suppose the MCC-545C is wired to detect a vehicle tip-over using the CTS and DTR signals and a gravity switch that closes if it does not remain mostly upright. The CTS output is used to enable tip-over detection. The DTR input is the signal on which tip-over event is detected. Normally open, the switch prevents DTR from receiving the CTS signal. If CTS is enabled and the vehicle tips over such that the switch closes, the CTS signal is presented to DTR. MCC-545 RF Modem CTS DTR Gravity Switch CTS is set to 5V on power-up, DTR is low if switch is open DTR will go high when the switch is closed To make the tip-over detection mechanism function, the CTS signal must be enabled so that it can be detected at DTR should the switch close. A good time to enable CTS – set CTS to high – may be when the MCC-545C is powered up. The command EVENT,RESET,SET,CTS will do this. The event is RESET. The action is SET,CTS. The “ignition” bit should also be set in the status word. The bits of the status register are numbered from low order to

The COLLISION bit is the same as BIT0, and the action “COLLISION” is used instead of “SET,BIT0” for clarity. The command EVENT,DIOHI,DTR,16,160,COLLISION defines an event that creates a vehicle collision report if the DTR signal is high for 1 second (16 sixteenths of a second). Collision is defined as the vehicle being tipped over. The event will clear and be ready for another event if the signal is low for 10 seconds (160 sixteenths of a second). DIOHI means “discrete I/O high” and DTR specifies the DTR discrete input. The parameters DIOHI,DTR,16,160 define the event. The parameter COLLISION defines the action. The User will create the event table with the following commands: Example 2: A Scanned Event - Marker-Drop Suppose the MCC-545C is wired to detect a marker-drop pushbutton using the CTS and DTR signals wired to a pushbutton switch mounted somewhere in a vehicle or aircraft. The CTS output is used to enable switch detection. The DTR input is the input signal on which marker-drop is detected. Normally open, the switch prevents DTR from receiving the CTS signal. If CTS is enabled and the marker-drop button pressed such that the switch closes, the CTS signal is presented to DTR. MCC-545 RF Modem CTS DTR Marker-Drop Switch CTS is set on reset in order to have a signal to detect on DTR DTR is scanned every 1/16 second for the high condition EVENT,STOP EVENT,DEL,ALL EVENT,RESET,SET,CTS EVENT,RESET,SET,BIT2 EVENT,DIOHI,DTR,16,160,COLLISION EVENT,START SAVE

To make the marker-drop mechanism function, the CTS signal must be enabled so that it can be detected at DTR should the switch close. A good time to enable CTS – set CTS to high – may be when the MCC-545C is powered up. The command EVENT,RESET,SET,CTS will do this. The event is RESET. The action is SET,CTS. The “ignition” bit should also be set in the status word, the command EVENT,RESET,SET,BIT2 will set the ignition bit. The bits of the status register are numbered from low order to high order, BIT0 through BIT15. The MARK bit is the same as BIT3, and the action MARK is used instead of SET,BIT3 for clarity. The command EVENT,DIOHI,DTR,16,160,MARK defines an event that creates a vehicle collision report if the DTR signal is high for 1 second (16 sixteenths of a second). The event will clear and be ready for another event if the signal is low for 10 seconds (160 sixteenths of a second). DIOHI means “discrete I/O high” and DTR specifies the DTR discrete input. The parameters DIOHI,DTR,16,160 define the event. The parameter “MARK” defines the action. The User will create the event table with the following commands: 5.6.5 Event Programming Command Summary There can be from 1 to 400 events defined in the event table including reset and scanned events. The following list shows all the command formats. Commands tagged “Yes” in the “Event” column each consume one entry in the event table. Some of the commands, tagged with “No”, are used to free up event table entries or control the operation of the event monitor. There is also a group table, and a text table. The group table is an array of 16 groups by 16 sensors. Each entry in the group table consists of a sensor type – discrete or analog – and a discrete bit identification or analog channel number.

Displays the current event and group table when no additional parameters are attached. All the event commands begin with “event,” followed by parameters. Command: EVENT, DEL, ALL Delete all events in the event table. Event table commands should be edited in script files and output to the MCC-545C using XTermW in order to reload the event table. This command does not delete the text messages or group definitions. Command: EVENT, DEL, number Delete only the numbered event from the event table. The events will be renumbered when one is deleted. Event table commands should be edited in script files and output to the MCC-545C using XTermW in order to reload the event table. Command: EVENT, START Start the event scanner. Scanned events will not be detected unless scanning is started. This command causes the event scanner to review the event table every 62.5 milliseconds for the occurrence of scanned events and the end of scanned events. This command also performs RESET events. On MCC-545C reset, the event scanner is started. Command: EVENT, STOP Stop the event scanner. Scanned events will not be detected while scanning is stopped. This command should be issued prior to clearing the event table (EVENT,DEL,ALL) and reprogramming it with events. This command does not affect the detection of the reset event. On MCC-545C reset, the event scanner is started again if the SAVE command was not issued while in the EVENT,STOP state. Command: EVENT, action A direct command for immediate action can be issued. This event command will not be added to the event table, but will cause the action to occur when the command is entered. This can be used to take action using

Command: EVENT, STATUS, {bit-name, or chan-name} This form of the command lets the operator display an immediate value for any discrete input bit or any ADC channel. For example: to display the status on the DTR input line, EVENT,STATUS,DTR<cr>. To display forward power, enter EVENT,STATUS,FPWR<cr>. Command: EVENT, RESET, action Define an action to be taken at power-up/reset. This is useful for setting control outputs at a known state or sending a message to a host system that the MCC-545C has been reset. These RESET actions will also occur if the event monitor is stopped, then restarted. This allows entering new RESET events into an existing table. Command: EVENT, DIOHI, bit-name, settle, holdoff, action Define an event that looks for a discrete input line to go to a high level. Parameter Description DIOHI Scan discrete input signal for high condition. bit-name Name of discrete input signal to be scanned for high level. (single or multiple inputs) settle Number of clock ticks for the input signal to settle at the high level before declaring an event holdoff Number of clock ticks for the analog input signal to settle at the low level to be armed for detecting the next event. action MCC-545C action to be taken when event is declared. See actions below. Logical combining of multiple discrete inputs is allowed. This is done by expanding the bit-name parameter of the command into a list on inputs separated by logic operator characters. For example, to test both the RTS and DTR inputs in one event, use the string “,DTR & RTS,” in the bit-name parameter. Up to 5 inputs can be used in a single event line. Any of the inputs can be “inverted” before the combination. For example, if the DTR input must be high and the RTS input low to trigger an event, use the string “,DTR & !RTS,” in the bit-name parameter.

The evaluation is done from left to right. There is no use of “(“ and “)” to form more complex ordering. The “0” and “1” values are used for “low’ and “high”. If the result of the combination of signals is “1”, then the DIOHI condition is satisfied. If the result of the combination is “0”, then the DIOLOW condition is satisfied. Both the DIOHI and DIOLOW event types can use the logical signal support. Table of Logical Operators: Operator Definition & AND | OR ! NOT Logical signal inversion Command: EVENT, DIOLOW, bit-name, settle, holdoff, action Define an event that looks for a discrete input line to go to a low level. Parameter Description DIOLOW Scan discrete input signal for low condition. bit-name Name of discrete input signal to be scanned for low level. (single or multiple inputs) settle Number of clock ticks for the input signal to settle at the low level before declaring an event. holdoff Number of clock ticks for the analog input signal to settle at the high level to be armed for detecting the next event. action MCC-545C action to be taken when event is declared.

Action MCC-545C action to be taken when event is declared. See actions below. Command: EVENT, CONT, action The CONT (Continue) event is used to define multiple actions to an event. An event definition command can be followed by any number of CONT commands and are considered to be an extension of the previous event command. For example: EVENT,DIOHI,DTR,1,1,SET,BIT0 ;Defines an event with one action EVENT,CONT,TXT,1 ;Add another action EVENT,CONT,UPDT,1 ;Add another action EVENT,CONT,CLR,T1 ;Add another action EVENT,DIOLOW,DTR,1,1,CLR,BIT0 ;End previous event definition, Start next one Command: EVENT, DO, action The DO event is provided for cases where an unconditional action is required. This type of event is not connected to other event lines as the CONT is. It is independent and will be initiated every time the event monitor executes the script item. For example: EVENT,DO,INC,C1 Command: EVENT, ADCHI, chan-name, hi-level, settle, holdoff, action

COMMAND DESCRIPTION PARAMETERS RANGE DIRECT, p, ETE, ON Defines the “reliable” type of message delivery. The source unit will retain each transmitted message and periodically retry them until the destination unit receives them and sends an end-to-end-acknowledgement for each message. It is possible for messages to be delivered out the destination units I/O port out of sequence when a retry has occurred. Duplicate messages will be filtered out. This method may be slower than when ETE's are turned off because there are more messages being sent through the network. DIRECT, p, ETE, OFF Disables the “reliable” type of message delivery. The source unit will not retain each transmitted message for retries. Each message will be deleted as soon as transmitted. It will be the responsibility of any receiving equipment to manage the message reliability. If any message gets lost in the RF network, then all characters in that message will be lost.

COMMAND DESCRIPTION PARAMETERS RANGE FEC,{HISTORY,n} The FEC,HISTORY,n command defined the number of transmissions that will be used by the algorithm to compute the number of errors correction parity bytes for each subsequent transmission. “n” can be set from 1-19. The size of the history queue determines how many points are averaged, and can effect the responsiveness to changes in the RF environment much like a low-pass filter. The longer the queue, the slower the response, and the shorter the queue, the quicker the response. The default value is 5. FREQUENCIES Shows the Active Transmitter and Receiver frequency and the frequency table where up to 10 frequency channels can be defined. To change/set the frequency of the radio is a two step process: Select the TX and RX Frequency, along with the channel number to be assigned to that frequency in the frequency table. Assign that channel to the frequency synthesizer from the frequency table.
