THIS DOCUMENT CONTAINS PROPRIETARY INFORMATION AND SUCH INFORMATION MAY NOT BE DISCLOSED TO OTHERS FOR ANY PURPOSES WITHOUT WRITTEN PERMISSION FROM SELEX Sistemi Integrati Inc. Copyright © 2006, SELEX Sistemi Integrati Inc. Operations and Maintenance Manual Model 2130 Marker Beacon 572130-0001 Rev A April, 2005 SELEX Sistemi Integrati Inc. 11300 West 89th Street Overland Park, KS U.S.A. 66214 THIS SHEET INTENTIONALLY BLANK SAFETY SUMMARY The following are general safety precautions that are unrelated to specific procedures and therefore do not appear elsewhere in this publication. These are recommended precautions that personnel should understand and apply during through the many phases of operation and maintenance. ELECTROSTATIC SENSITIVE DEVICES PRECAUTIONS Since most modules used in all models of equipment have Electrostatic Discharge (ESD) sensitive devices included in them, all modules should be considered sensitive to electrostatic discharge. Handling in the field shall be the same as in the factory. Each system is shipped with a wrist strap that must be worn while maintaining the equipment. The wrist strap shall be fastened to the equipment chassis either in the designated plug-in or attached to the equipment chassis with the alligator clip. The wrist strap must be used before any modules are removed from the equipment and at all times while handling the modules until they are placed in a protective environment such as an anti-static bag. Modules or boards must not be placed on any non-conducting surface such as wooden work benches, painted metal work benches, plastics, or technical manuals. Any work surface to be used must have a conducting mat placed on it and attached to earth ground. The mat and additional wrist straps can be obtained from SELEX Sistemi Integrati Inc. KEEP AWAY FROM LIVE CIRCUITS Operating personnel must at all times observe all safety regulations. Under no circumstances should any person remove any protective covers that expose lethal voltages. Do not replace components or make adjustments inside the equipment with primary power supply turned on. Under certain conditions, dangerous potentials may exist when the power is in the off position, due to charges retained by capacitors. To avoid casualties, always remove power and allow time for the capacitors to discharge before touching it. DO NOT SERVICE OR ADJUST ALONE Under no circumstances should any person reach into or enter the enclosure for the purpose of servicing or adjusting the equipment except in the presence of someone who is capable of rendering aid. RESUSCITATION Personnel working with or near high voltages should be familiar with modern methods of resuscitation. THIS SHEET INTENTIONALLY BLANK SELEX Sistemi Integrati Inc.

The following warranty is applicable in all cases, except where modified or superseded by specific contract terms. Contact SELEX Sistemi Integrati Inc. if clarification is required. A. The Manufacturer warrants to the original Purchaser, subject to the limitations and exclusions stated below, that mechanical and electrical parts of products which it manufactures, (the “Products” will be free of defects in materials and workmanship for a period of (I) one (1) year from the date of installation or (ii) 18 months from the date of shipment, whichever first occurs (the “Warranty Period”). B. If the Customer believes a Product is defective, notice thereof shall be provided to the Manufacturer’s Customer Service Department at the address provided on the cover page and (if applicable) to the selling distributor. A defect in material and workmanship covered by this warranty shall be deemed to have occurred only if, and as of the time when, the Manufacturer is notified in writing by the Customer, within the Warranty Period, that the Product has become defective, and the Manufacturer’s personnel verify that the said Product, in fact, does not comply with the warranty provided hereunder and it is determined that: (i) The Products, during the entire Warranty Period, have been operated within normal service conditions, recommended by the Manufacturer and recognized in the industry, and (ii) The Products have been installed and adjusted according to the Manufacturer’s procedures as stated in the Instruction Manual or other instructions supplied in writing by the Manufacturer. C. Failures caused by lightning or other acts of God, or power surges, are not considered to be defects in materials and workmanship and are not covered under this warranty. Routine Maintenance and calibration are also not considered to be defects in materials and workmanship and are not covered under this warranty. Any change, modification or alteration of the Manufacturer’s Products not specifically authorized by the Manufacturer will void this warranty. D. If it is determined that the conditions for warranty coverage, as described above, have been satisfied, the Manufacturer shall repair or replace the defective products or parts thereof in accordance with the following procedures: (i) Customer will contact the Manufacturer’s customer Service Department which will issue the Customer a Return Authorization (RA) number. (ii) The Component, defective part, or Product, as appropriate, shall be returned to the Manufacturer for inspection, freight prepaid by the customer. The Component, defective part, or Product MUST be packaged with an industry standard anti-static protective bag sufficient to prevent any ESD intrusion during handling and shipment, and MUST ALSO be packaged to protect from damage due to rough handling encountered during shipment. FAILURE TO COMPLY WITH THIS REQUIREMENT WILL VOID THE WARRANTY OF THE RETURNED ITEM. The RA number must be clearly displayed on the exterior of the shipping container. No shipments will be accepted without a RA number. All custom duties, fees, etc. will be paid by the Customer. (iii) If, upon inspection it is determined by Manufacturer’s personnel that the Product or component thereof is indeed defective and covered by this warranty, then Manufacturer, at its option, may either repair the Product or defective components thereof and return the same to the Customer or ship a replacement for the defective Product or part thereof, freight paid. All customs duties, fees, etc. will be paid by the Customer. The Product or component thereof will be returned to the Customer utilizing a shipping mode similar to that used by Customer to ship the same to the Manufacturer. (iv) If, upon inspection by Manufacturer, it is determined that the Product or component thereof was not defective or was not covered by this warranty, then the cost of all of Manufacturer’s inspections and the return shipping charges will be charged to Customer. E. The Manufacturer reserves the right to make modifications and alterations to Products without obligation to install such improvements on, in, or in place of theretofore manufactured products of Manufacturer.

MODEL 2130 MARKER BEACON 1. GENERAL INFORMATION AND REQUIREMENTS 1.1 Introduction This technical manual contains information required to operate and maintain the Model 2130 Marker Beacon Equipment. It incorporates the equipment description and specification data, a thorough technical description, complete operating procedures, operational standards and tolerances, procedures specifying when and how to perform routine and corrective maintenance, a comprehensive parts list, detailed installation instructions and support schematics and drawings. 1.2 Equipment Description Refer to Figure 1-1. Marker Beacons are used to provide an aircraft both an aural and visual indication of station passage. Station identification is provided by both a modulation frequency and keying code. The Marker Beacon transmits an upward-directed elliptical signal of information at a frequency of 75-MHz. Each Marker Beacon signal is amplitude modulated by an audio tone which is Morse code keyed. Both the audio tone frequency and the keying are distinctive according to the marker's location. Figure 1-1 Marker Beacon The Marker Beacon is used in two distinct operational environments: en-route or terminal facility. Terminal application Marker Beacons or, as they are more commonly called, Instrument Landing System (ILS) Marker Beacons, are located along the extended runway centerline and are used as distance-to-touchdown indicators to indicate significant points along an instrument approach path. These types are classified as the Outer, Middle, and Inner Marker Beacon systems. Fan Marker Beacons may also be associated with the ILS to serve as a localizer step down fix or Missed Approach Point (MAP) for circling approaches to secondary airports. Rev. A April, 2005 1-1 This document contains proprietary information and such information may not be disclosed to others for any purposes without written permission from SELEX Sistemi Integrati Inc. MODEL 2130 MARKER BEACON When used for en route applications, the Marker Beacon is configured as a fan marker. It can be used with other Navigational Aid equipment and its use depends upon instrument flight procedural applications. For ILS operation, an outer marker is typically located 4 nautical miles from the runway threshold; this location normally coincides with the point on the ILS approach at which the glide slope altitude equals the intercept altitude. A middle marker is typically located 3,500 feet from the runway threshold; this location normally coincides with the point on the glide path at which the Decision Height (DH) is located for Category I operations 200 feet above the touchdown zone elevation. The inner marker is only installed for Category II and III ILS approaches, and is located approximately 1000 feet from the runway approach threshold, coinciding with the nominal Category II decision height of 100 feet. The inner, middle and outer marker antennas are single five element Yagis. The Marker Beacon (Figure 1-2) is of modular design and completely solid-state. Both single equipment and dual equipment transmitters are available. Battery backup (Figure 1-6) is optional and provides power in case of primary AC power failure. Operating control of the Marker Beacon system is by a Portable Maintenance Data Terminal (PMDT) The PMDT is an IBM compatible personal computer running SELEX SISTEMI INTEGRATI INC. proprietary application software. The two antenna configurations (pole and tower) are shown in Figure 1-4. Microprocessor-controlled monitoring and built-in test equipment are an integral part of the equipment. This allows continuous monitoring of all required parameters as well as the testing, control, and display of voltages, currents, and frequencies. The Marker Beacon can be remotely monitored through: a. b. c. Dedicated telephone lines to the Model 2238 Remote Status Control Unit. Optional radio link operating at either 900 MHz or 2.4 GHz. Remote Maintenance Monitoring (RMM) - Switched telephone lines and modem integrated within the 2130 Marker Beacon allow for interface to remote monitoring points using the PMDT software. 1.2.1 Monitoring Systems A high integrity integral monitoring system incorporated in the Marker Beacon system to provide fault detection by monitoring the transmitted signals and initiating automatic station transfer to a standby transmitter or shutdown in the event of an out-of-tolerance condition. Dual, parallel monitoring channels are included for measurement of important signal parameters for the On-the-Air Transmitter and Standby Transmitter. Independently adjustable pre-alarm (maintenance alert) indications are included for all executive monitoring parameters. All executive and maintenance alarm indications are provided both locally at the station and remotely through the Remote Maintenance Monitoring (RMM) system. Integrity of the monitors is assured by certification testing using a built-in Test Generator. Failsafe design of the monitors ensures the removal of Navigation and Identification signals and the transmission of a warning signal to the remote control and monitoring points in the event of a failure in the monitoring system itself. Failsafe testing of the monitors and control circuits has been performed to verify that any single failure of a component, open or short in the monitor(s) or control circuit will either result directly in an alarm condition, or will not alter any alarm threshold level to allow an out-of-tolerance condition to occur without detection. The monitoring system includes a bypass capability to disable the automatic station control action during adjustment and maintenance. Front panel amber "bypass" and "alarm" lights are illuminated any time the integral or standby transmitter 1-2 Rev.

MODEL 2130 MARKER BEACON All monitored and internally measured system parameters are available for display via the station RS-232 communications port and the Portable Maintenance Data Terminal (PMDT). The parameters are also available remotely through the Remote Maintenance Monitoring (RMM) system. 1.2.2 Station Control System The station control system provides for manual control of the station during maintenance operations and for automatic control during unattended operation. The Local Control Unit provides the following system features: a. b. c. d. e. f. g. h. i. Local On/Off control and status indication of the transmitting equipment. Selection of which transmitter operates as Main and which operates as Standby. Monitor bypass capability with indications for the Integral and Standby Transmitter monitoring systems. Provisions for either Local or Remote control of the transmitting equipment. System reset capability. Automatic transfer capability from the Main to the Standby transmitting equipment (or shut down for single transmitter) in response to monitor alarm conditions following an adjustable preset alarm delay period. The Standby transmitter is operated in the "hot standby" mode for CAT III stations, and may be operated as either a "hot or cold" standby for CAT II or CAT I operations. When operated in the "hot standby" mode, the standby transmitter is placed on line immediately at the end of the alarm delay period. When operated in the "cold standby" mode, the standby transmitter is activated following a preset alarm delay period (20 seconds, minimum). Two automatic station restart attempts following shutdown; the first after a time delay of 50 seconds, and the second after a fixed delay of 15 minutes. If either restart attempt is successful, all delay timers are reset to their original condition. If the restart is not successful then a manual local or remote restart is required. If an alarm occurs the alarm indicator at the RCSU is activated. Automatic station transfer to and from the no-break standby battery system in the event of a primary AC power failure and subsequent restoration; and automatic turn-on following restoration of primary AC power should the standby battery system be depleted. Batteries automatically recharge on restoration of primary power. In addition to the control features above, system control and monitoring functions as well as verification and adjustment of proper transmitting and monitoring parameters are available using Windows™ based displays via an RS-232 communications port on the transmitter cabinet and a Portable Maintenance Data Terminal (PMDT). The system is password controlled such that system adjustments are possible only with entry of the proper security codes. A second RS-232 communications port is connected to a modem for system operation and monitoring via a dial-up telephone line to a remote location. 1.2.3 Remote Control and Status Equipment (Optional) An optional Remote Status and Control Unit (RCSU) and up to three Remote Status Units (RSU) are available for remote control and status monitoring of the Marker Beacon station.. Provisions are included for On/Off status monitoring of auxiliary transmitting equipment which may be installed at the Marker Beacon station. The RCSU is a computer using Windows™ type displays and is designed for installation in a control tower equipment room. The RSU/s are driven by the RCSU and are designed for installation at controller positions within the tower. Features of the RCSU system include: a. b. c. d. e. On/Off, and Transfer control for the Marker Beacon. Status indications on the RCSU and RSU(s) for the Marker Beacon facility. Interlock capability on the primary RSU for Localizer, Glideslope, Marker Beacon and DME systems located on opposite ends of the same runway. Runway-Selected indication is provided on all RSUs. Remote access to the RMM system on any of the Localizer, Glideslope or VOR stations through the RCSU computer via modem or TCP/IP network. Only a single dedicated control line is required from the RCSU to each of the connected stations. 1-4 Rev.

MODEL 2130 MARKER BEACON 2. TECHNICAL DESCRIPTION 2.1 Introduction The Marker Beacon is comprised of a Local Control Unit, RMS Processor, one Amplifier/ Monitor Assembly for single equipment or two Amplifier/Monitor Assemblies for dual equipment. In addition the power panel assembly contains the Battery Charging Power Supply (BCPS) with one power supply for single equipment and two power supplies for dual equipment. The Marker Beacon is provided with battery backup capability through the BCPS function. The Amplifier/ Monitor Assembly provides frequency synthesizer for signal generation, an RF amplifier and monitor functions. 2.2 Antenna Operation The required coverage pattern of each Marker Beacon is elliptically shaped as defined in Table 2-1, with the minor axis oriented along the course centerline. The Marker Beacon transmitter power is capable of being adjusted to provide the required signal (1700 microvolts) within the bounds of the minimum and maximum dimensions of the axes. The vertical coverage of the Marker Beacon is such that the received signal rises to 3000 microvolts/meter near the center of the ellipse.

Provides an elliptical radiation pattern with its minor axis parallel to the course line when cut by a horizontal plane with a minimum major-to-minor axis ratio of 1.5 to 1.0. Coverage is measured along the Localizer course line while descending along the commissioned glide path. With the Marker Beacon power adjusted for the desired coverage pattern, signal strength sufficient to provide an indication on the Marker Beacon receiver extends at least 3000 feet above the station. The major axis width is sufficient to provide sufficient signal strength to a standard Marker Beacon receiver at the 75 microampere edge-of-course line at the altitude established by the instrument approach procedure established for the runway. 2.3 Marker Beacon Transmitter Theory of Operation 2.3.1 Marker Beacon Amplifier/ Monitor Theory of Operation The Marker Beacon Amplifier/Monitor CCA performs the RF signal generation and monitoring for the Marker Beacon transmitter cabinet. There is one Amplifier/ Monitor for single equipment and two provided for dual equipment configuration. The Amplifier/Monitor CCA is located on the inside left wall of the Marker Beacon cabinet. For a single configuration the transmitter output cable and Integral monitor cable connect directly to the exterior interface box. For a dual transmitter configuration the transmitter output connects to the LCU CCA. Rev.

MODEL 2130 MARKER BEACON 2.3.1.1 Marker Beacon Amplifier/ Monitor Block Diagram Theory Refer to Figure 2-1. The Amplifier/Monitor includes a frequency synthesizer that can be programmed to 75 MHz. In addition the frequency can be set to 4 kHz higher or 4 kHz lower than 75 MHz. The synthesizer channel is set from the PMDT interface. The output of the synthesizer is amplified in two stages to obtain 2.5 Watts. A low pass filter in the output rejects harmonics and high frequency spurious signals. The low pass filter is followed by a directional coupler for monitoring forward and reverse power. A jumper selectable 6 dB attenuator allows for the amplifier to operate down to the lower power level of the Inner Marker Beacon. The RF amplifier is modulated class A. The directional coupler forward and reverse power signals are fed back into an IF detector and into an A/D converter for measurement. In addition the monitor return from the antenna and the standby transmitter signal from the LCU transfer logic is fed into the detector and the A/D converter for processing. The microprocessor is an Analog Devices Blackfin, BF532. This is a 16 bit processor running at 400 MHz internally. This is possible by an internal phase locked loop. Flash memory is provided to store program information A non-volatile memory that provides long term storage of setup information is used along with a real-time clock crystal in conjunction with the internal used to provide day/date/time information. Setup information is provided to the Amplifier/ Monitor through the serial communications channel to the RMS CCA. The RMS communicates to the PMDT and any setup information is passed to the Amplifier/ Monitor from the RMS. Figure 2-1 Amplifier/Monitor Block Diagram 2-2 Rev.

MODEL 2130 MARKER BEACON 2.3.1.2 Marker Beacon Amplifier/ Monitor Detailed Circuit Theory 2.3.1.2.1 Power Supply Refer to Figure 11-12 Sheet 2. The power for the Amplifier/Monitor enters on J3 pins 21, 22, and 23. The 12 volts is converted to 5 VDC by DC-DC Converter PS1. The output of PS1 enters U19, a linear voltage converter that drops the voltage to 3.3 VDC and is labeled DVCC for use as the digital supply voltage. The 12 VDC also enters U20 where it is converted by a linear converter to +5 VDC and labeled VCC. This voltage powers the TXCO, U5. The 12 VDC is converted to +5 VDC by U16. This 5 VDC is used by RF amplifiers U17 and U18 as the supply voltage for operation. Separate power supplies are used to provide noise immunity from one function of the amplifier to another. 2.3.1.2.2 Synthesizer Refer to Figure 11-12 sheet 2. Integrated circuit U13 acts as the loop controller for the synthesizer circuit. Microprocessor U8 sets the channel information into U13 by serial shifting data into the circuit. Data enters on the line marked Synth_data. The data is clocked into the circuit by Synth_clock. When programming is complete Synth_LE is toggled. The signal Synth_lock when low indicates that the synthesizer is locked on frequency. The loop filter is comprised of C54, R22, C56, R21 and C58. The output of the loop filter controls the VCO. The voltage into the tune input sets the output frequency of the VCO U15. Power for the VCO enters on J3 pin 20. This voltage originates on the LCU and is one of the duplicated methods to disable the transmitter. The VCO power is regulated to 10 volts DC by low voltage drop regulator U14. The output of U14 is filtered by caps C57, C113, and C62 and enters the VCO U15. The output of the VCO is attenuated by R29, R30 and R32 and amplified by U17. The output of U17 is split in two by R34, R37 and R35 resulting in a 6 dB power loss. The combination of R35, R36 and R28 forms another attenuator prior to entering the VCO controller U13 where the signal is divided, compared against the reference frequency and the VCO control voltage corrected. The other output of the power divider formed by R34, R35 and R37 enters U18 and amplified. Resistors R42, R43 and R46 form an attenuator prior to entering U21. U21 amplifies the signal and provides an output level of approximately 10 mW and is marked PA_DRIVE. Refer to Figure 11-12 sheet 4. The modulation for the RF amplifiers originates from U8 microprocessor. Serial data is transferred to D/A converter U37. The signal from U37 is low pass filtered by U24B and U24C. Op Amp U24A combines the detected signal from U26A and U24A with the modulation from U24C. U24A drives FETs Q4, Q5 and Q10 as a class A Modulator. Op Amp U30D takes the detected signal and amplifies to TTL level for monitoring. FET Q2 is the first amplifier stage that provides approximately 10 dB of gain. The input from the frequency synthesizer section enters at PA_DRIVE. The modulation enters through R51 and L13. The gate bias voltage enters through R52. The gate voltage is set by potentiometer R54 and R53 and derived from a precise voltage set by R55 and zener diode CR7. Capacitors C99 and C101 filter this 7.5 VDC to eliminate noise. 2-4 Rev.

MODEL 2130 MARKER BEACON The RF output of Q2 enters the gate of Q3 where it is amplified approximately 13 dB. The modulation enters from R50, L14, L15 and L16. The gate bias voltage enters through R57. The gate voltage is set by potentiometer R56 and R58.Resistors R50 and R51 are used to set measure the current to Q2 and Q3 in order to set the bias voltage with R54 and R56. The output of Q3 enters the low pass filter formed by L17, C109, L19, C111, L20, C113, L21, and C114. This low pass filter is used to reject all higher harmonics of the fundamental frequency (75 MHz). The output of the low pass filter enters the directional coupler DC1. The forward power port is pin 3 and the reverse power port is pin 6. The output of the directional coupler enters position 2 of TB1. TB1 and TB2 select whether the output passes straight through to the output connector or through a 6 dB attenuator. With both TB1 and TB2 set to connect position 1 to position 2 there is no attenuation in the output. With TB1 and TB2 set from position 2 to 3, 6 dB of attenuation is added prior to the output connector. Either the Standby Transmitter, Integral Monitor return, Forward Power or Reverse Power may be selected by the microprocessor U8 to enter integrated circuit U31 where the RF signal is converted to a detected signal and then enters analog to digital converter U32. Integrated circuit U32 is an 8 channel A/D converter that is connected to the data bus of the microprocessor U8. The A/D converter allows for conversion of various analog inputs for integral monitor, standby monitor, forward power, reverse power and fault isolation inputs. 2.3.1.2.3 Microprocessor Digital Section Refer to Figure 11-12 sheet 1. Integrated circuit U8 is the Analog Devices Blackfin, BF532 microprocessor. This is a 16 bit processor running at 400 MHz internally. This is possible by an internal phase locked loop. Integrated circuit U7 is the voltage monitor circuit that provides a reset into U8 if the voltage becomes low. Oscillator U5 provides a precise 10 MHz frequency source to U8 through U6D. Inverters U6B and U6F buffer the clock signal for use in the serial device (UART) and the synthesizer. Flash memory (U1 and U2) is provided to store program information. A non-volatile memory (U3) provides long term storage of setup information is used along with a real-time clock crystal in conjunction with the U8 internal circuitry to provide day/date/time information. External static random access memory (U4) is also provided for additional temporary data storage. The FET circuit Q1 along with L1, CR3 and C37 provides a 1.2 voltage from the 3.3 VDC source for the internal power to the microprocessor U8. Integrated circuit U9 is a dual universal asynchronous receiver and transmitter (UART). This integrated circuit provides the serial communications interface to the RMS CCA and a spare serial channel. Integrated circuit U11 converts the logic level of 3.3 VDC to RS232C levels. The U11 circuit also contains a power supply to generate +/- 8 Volts DC for the RS232 outputs. The RMS port, the spare channel and the software debug port inputs and outputs are level translated by U11. Integrated circuit U10 provides for address decoding so that microprocessor U8 can select between the NVRAM, UARTA and UARTB and the Analog to Digital converter channels. 2.3.2 Marker Beacon RMS Theory of Operation The Remote Monitoring Subsystem (RMS) gathers data from various sensors and internal monitoring points within the Marker Beacon station and controls various functions of the Marker Beacon station. In order to accomplish this, the RMS communicates with up to two station monitors through serial interfaces. It also gathers analog and status data directly from the various sensors. The station status and various data is reported to the Local Status/Control Unit (LCU) and to the Remote Control and Status Unit (RCSU) through a modem. 2.3.2.1 RMS CCA (012147) (1A4) Block Diagram Theory Rev. A April, 2005 2-5 This document contains proprietary information and such information may not be disclosed to others for any purposes without written permission from SELEX Sistemi Integrati Inc. MODEL 2130 MARKER BEACON Refer to Figure 2-2. The Remote Monitoring System (RMS) CCA distributes power, performs communications, provides system interconnections via nine serial ports plus a parallel port, and facilitates monitoring/control in a single or dual Marker Beacon system. The RMS CCA receives battery-backed DC power from the BCPS CCA at DB37 connector J1 and directly routes it to Marker Beacon1 and Maker Beacon2 on DB25 connectors J3 and J4. These battery-backed DC power supplies are also diode-OR’D and regulated into +3.3V, +5V, +/-12Analog, and +/-12Digital supplies for use by the RMS CCA to power the microcontroller and all of its associated circuitry. The U8 microcontroller utilizes external flash ROM, non-volatile RAM (NVRAM), synchronous dynamic RAM (SDRAM), a voltage supervisor/reset circuit, and an oscillator to form the core microcomputer. The U8 microcontroller also includes internal watchdog/reset circuitry, a direct memory access (DMA) controller, serial ports, and general purpose input/output (I/O). Microcomputer peripherals include a real-time clock (RTC), a digital-analog (D-A) converter, an analog-digital (A-D) converter, universal asynchronous receiver/transmitters (UARTs), a parallel port interface (PPI), and more general purpose I/O. The U8 microcontroller’s flash ROM is factory programmed using the J9 SPI boot header while factory debug is accomplished using the J8 emulator header, the JP6 debug header, and the JP4 PMDT RS232 header. Test header J10 also facilitates factory testing. None of the aforementioned connectors and headers will be used by the customer in the field. RMS communication to the LCU CCA occurs via the parallel port J2 PPI connector. The LCU also returns system control signals through J2 such as *TEST (lamp test) and *MRESET (master reset). Configuration switches on the RMS define the system set-up to both the RMS and the LCU through the J2 connector. The U8 microcontroller communicates serially through one internal and eight external UARTS. Depending on the configuration switch set-up and header straps, the serial communications are converted to modem tip/ring, RS232, or universal serial bus (USB) levels. Assuming the PMDT and RSCU channels are configured as tip/ring modems, their signals are routed to the GP I/O TB2 connector and can be heard at the on-board speaker along with Ident signals from Marker Beacon1, Marker Beacon2, Far Field Monitor1 (FFM1), and Far Field Monitor2 (FFM2). The Ident audio signals are selected or deselected through a multiplexer. If the PMDT is not configured as a dial-up tip/ring modem, three other options are possible. The PMDT may be connected to USB connector J7 with header JP5 strapped for USB operation. The PMDT may also be connected to the DB9 EXT_RMM (external remote maintenance monitor) connector J6. The third option (in factory only) has the PMDT connected to RS232 header JP4 and header JP5 strapped for RS232 operation. If the RCSU is not configured as a direct-connect tip/ring modem, the other option is a cell phone or radio modem attached at DB9 connector J5. The RMS CCA provides spare digital outputs, spare digital inputs, spare analog inputs, an external temperature sensor input, a smoke detector input, and an intrusion sensor input on GP I/O connectors TB1 and TB2. The spare analog inputs along with the power supplies are multiplexed to the A-D converter for monitoring. The D-A converter is used to generate filtered test signals routed to Marker Beacon1 connector J3 and Marker Beacon2 connector J4 for operational limit testing. These test signals are also routed to the multiplexed A-D converter for RMS self-monitoring. 2-6 Rev.

Battery-backed DC power in the range of +10.4VDC to +15VDC enters the RMS CCA on J1-19 and J1-17 and is diode-OR’D by CR3 and CR4 to create RADIO_V+. RADIO_V+ is directly regulated to +3.3VDC by DC-DC converter PS1 and can be measured on test point TP7. The voltage level of RADIO_V+ is lowered by CR8, CR9, and CR10 before regulation by DC-DC converter PS3, creating +15V and -15V which can be measured on TP15 and TP16. The -15V output of PS3 is filtered by C44, L5, and C53 before regulation to -12ANA by U10 and is measurable at TP4. The -15V is also directly regulated to -12DIG by U13 and is measurable at TP5. The +15V output of PS3 is filtered by C54, L6, and C56 before regulation to +12ANA by U11 and is measurable at TP6. The +15V is also directly regulated to +12DIG by U14 and is measurable at TP8. The +12DIG is further regulated to +5DIG measurable at TP9. The last power supply for the RMS is 1.2V and can be measured at TP3. The U8 microcontroller generates a pulse-widthmodulated (PWM) signal at U8-4 and U8-5 which drives transistor Q1. Diode CR2, inductor L1, and capacitor C37 complete the DC-DC converter which creates the +1.2VDC used for powering the core of the U8 microcontroller. The U8 microcontroller accesses its program from U1 and U2 flash ROM. System variables are stored in U3 NVRAM. Further storage and execution area is available in the U4 SDRAM. Clock Oscillator Y2 generates the heartbeat for the U8 microcontroller as well as the U25 and U20 UARTs. Voltage/reset supervisor U7 monitors +3.3V and resets U8 if +3.3V drops too low or if an external reset from the LCU enters via J2-31. Rev.

MODEL 2130 MARKER BEACON All address and data lines are buffered through drivers U57, U58, U59, U60, and U61 before connecting to any memorymapped device except those to the U4 SDRAM, which are directly connected to U8. The drivers reduce the address and data line capacitance seen by the U8 microcontroller so that the U4 SDRAM may operate at very high speeds. The CR5 STATUS light emitting diode (LED) provides visual indication of proper operation of the U8 microcontroller and that RADIO_V+ power is present. Three grounds are utilized on the RMS CCA. Earth (EGND) ground is the drain path for all transient voltage suppression (TVS) devices. The E1 lug and several mounting holes provide the route for EGND to leave the board. EGND is referenced to digital ground (DGND) through inductor L2. DGND is the common point for all high-speed, high current signals and is referenced to analog ground (AGND) through resistor R35. AGND is the quiet common point for signals that must be measured accurately or maintain stable levels. The U15 real-time clock (RTC) keeps time, day, week, and year information and is clocked by oscillator U9. Both U15 and U9 are battery-backed by battery B1. Battery B1 can be disconnected at header JP3, usually only done for storage or shipment of the RMS CCA or replacement of B1. The U15 RTC communicates serially to the U8 microcontroller at U15-6 and U15-5. The U8 microcontroller and U1/U2 flash ROMs can be programmed and debugged in the factory using the J8 emulator and J9 SPI Boot headers. The DB37 J1 BCPS connector’s primary function is routing analog signals between the BCPS and RMS/MKR1/MKR2/LCU CCAs. The Marker1 J3 and Marker2 J4 connectors are both DB25 types while the J2 LCU is a 60 pin shrouded header. Input buffer U45 is used to read the states of REMOTE/*LOCAL (J2-19), BATT1_FAULT (J1-37), BATT2_FAULT (J136), ON_BATT1 (J1-35), ON_BATT2 (J1-34), and *TEST (J2-44); all of which are pulled up by resistor network RN9. *TEST when low will cause the lighting of all LEDs on the LCU and BCPS CCAs but does not affect the RMS, FFMX, or Marker BeaconX LEDs. Input buffer U44 is used to read the states of SPARE_DIN1 (TB2-2), SPARE_DIN2 (TB2-3), SPARE_DIN3 (TB2-4), SPARE_DIN4 (TB2-5), DED/*RADIO, DIALUP/*EXT, SMOKE_DETECTOR (TB1-10), and INTRUSION_SENSOR (TB111); all of which are pulled up by resistor network RN8 and resistors R106 and R107. DED/*RADIO and DIALUP/*EXT are strapped at header JP1 to determine tip/ring versus RS232 modem operation. Latches U38 and U32, input buffer U42, and RS422 driver U34 comprise the bidirectional parallel port interface PPI between the RMS and the LCU CCAs. Data transfers occur on the PDATA0 (J2-3) through PDATA7 (J2-10) bus. This PDATA bus is pulled down through resistors on the LCU CCA. The RMS is considered the master and the LCU is considered the slave. Analog multiplexor U52 switches Ident signals FFM1_IDENT (J1-3), FFM2_IDENT (J1-22) MKR1_IDENT (J3-5), and MKR2_IDENT (J4-5) through to R86, R85, and C134 under control of latch U53. Resistor R86 and R85 divide the Ident tone to audio input levels before feeding audio amplifier U27 through coupling capacitor C134. Each Ident tone can be individually switched through the U52 multiplexor as well as DGND; which will not have an audio tone (Ident mute). FFM TX Disable header JP2 will normally not connect the FFM1 or FFM2 TX to J1-1 or J1-20 to prevent interference with a direct-connected Far Field Monitor. This option header may be used differently in future designs. 2-8 Rev.

MODEL 2130 MARKER BEACON Quad UART U25 provides four serial ports of the RMS CCA; the local PMDT, the Marker Beacon1, the Marker Beacon2, and the FFM1 ports. The local PMDT has two possible connection means; either through USB connector J7 or RS232 header JP4. PMDT local select header JP5 must be strapped properly for either of them to operate. If the RS232 option is selected (normally only at the factory), U36 performs the RS232-TTL level conversions. If the USB option is selected, U63 performs the USB-TTL translations. U63 is clocked by crystal Y3 and serial EEPROM U5 may be used for USB ID storage. U63 also toggles LEDs CR11 and CR12 to indicate transmission and reception of USB data. RS232-TTL converter U36 also translates Marker Beacon1 and Debug header JP6 signals. Debug header JP6 is normally only used at the factory. The debug signals route to the microcontroller at U8-81 and U8-82. RS232-TTL converter U37 translates the Marker Beacon2 and FFM1 signals before routing to/from quad UART U25. General purpose I/O from TB1 and TB2 are transient protected by CR27 through CR31 and CR36 through CR44. Resistors R127 through R130 pull down SPARE_ANA1 (TB1-6) through SPARE_ANA4 (TB1-9) before they route to TEST header J10 (normally used only at the factory) and multiplexor U33. Test header J10 has most of the general purpose I/O as well as the PMDT and RCSU tip/ring signals. Exterior temperature is sensed as EXT_TEMP_TVS- (TB1-2), transient protected by CR25, scaled by R102 and R103, and buffered by U55:A. The formulae needed to convert the output voltage measured at TP26 to temperature are shown near U55:A. Interior temperature is sensed by U39, scaled by R104 and R105, and buffered by U55:B. The same formulae apply for interior temperature as exterior temperature. Quad UART U20 provides four serial ports of the RMS CCA; the remote PMDT, the RCSU, the FFM2, and the spare Marker BeaconX ports. The remote PMDT has two possible connection means; either through tip/ring modem U24 via TB2-10 and TB2-11 (Dialup) or RS232 DB9 connector J6 (*External RMM). Modem select header JP1-4 must be strapped properly for either of them to operate. If the RS232 option is selected (*External RMM, JP1-4 strapped to JP1-6), U41 performs the RS232-TTL level conversions. If the tip/ring modem option is selected (Dialup, JP1-4 strapped to JP1-2), the U24 socketmodem performs the tip/ring to TTL translations. Socketmodem U24 also toggles LEDs CR13, CR14, CR15, CR16, and CR17 to indicate ring, transmission, reception, and handshake status of the dial-up modem. Two options also exist for the RCSU modem; either through tip/ring modem U26 via TB2-12 and TB2-13 (Dedicated) or RS232 DB9 connector J5 (*Radio). Modem select header JP1-3 must be strapped properly for either of them to operate. If the RS232 option is selected (*Radio, JP1-3 strapped to JP1-5), U40 performs the RS232-TTL level conversions. If the tip/ring modem option is selected (Dedicated, JP1-3 strapped to JP1-1), the U26 socketmodem performs the tip/ring to TTL translations. Socketmodem U26 also toggles LEDs CR18, CR19, CR32, and CR33 to indicate transmission, reception, and handshake status of the dedicated modem. In summary, the strapping of modem select header JP1-4 and JP1-3 selects which sets of TTL level signals are directed to/from quad UART U20 by buffers U22 and U28. The tip/ring modem signals of the U24 dial-up socketmodem are filtered and transient protected by FL1, FL2, and CR20 before routing to TB2-10 and TB2-11. The tip/ring modem signals of the U26 dedicated socketmodem are isolated from common-mode noise by transformer T1, then filtered and transient protected by FL3, FL4, and CR34 before routing to TB2-12 and TB2-13. U41 performs the RS232-TTL level conversions for the FFM2 port and U40 performs the RS232-TTL level conversions for the spare Marker BeaconX port. Either spare Marker Beacon1 or spare Marker Beacon2 port is selected depending on the strapping of Marker Spares header JP8. Both the dial-up U24 and dedicated U26 socketmodems have audio outputs routed to Audio header JP7. If enabled, the audios of the socketmodems, as well as Ident audio mentioned previously, are amplified by U27 and presented at speaker SPK1. Audio header JP7-5 and JP7-6 must be strapped together to enable the amplifier. Rev.

MODEL 2130 MARKER BEACON U33 and U16 comprise a 32 to 1 channel analog multiplexor controlled by latch U54 and inverter U17:D. All power supplies with potentials greater than ±12V are scaled down by resistor networks RN12 and RN13 before presentation to U33. Voltage reference U30 serves both as a reference check for the U31 A-D converter as well as the base reference for D-A converter U56. Buffer amplifier U29 presents the selected analog channel to A-D converter U31. Converter operation is controlled by the latch U54 A_D_R/*C signal, with a TTL low initiating a conversion. Conversion status and data bus output of the converter are read through buffers U46 and U47. Resistor networks RN11 and RN10 pull up the converter data bus during tri-state conversion periods. Buffer inputs U46-3 and U46-4 are reserved to denote any major hardware revisions to the RMS CCA that might occur in the future. Operational amplifiers U35:C and U35:D and associated components form a full-wave rectifier/amplifier circuit for the system AC current sensed on the BCPS CCA and routed on-board from J1-9. Potentiometer R93 will scale the output of this circuitry to fit the ratios shown near TP23 and R93. Operational amplifier U35:B buffers the System1 AC voltage sensed on the BCPS CCA and routed on-board from J1-29 after it is scaled by potentiometer R99 and transient protected by CR22. The scaled voltage can be measured at TP24 and will behave according to the formula shown near this test point and resistor R98. Operational amplifier U35:A and associated circuitry perform the same function for System2 AC voltage from J1-28 as U35:B discussed previously. Instrumentation amplifier U48 amplifies the differential signals Batt1_Curr+ and Curr- sensed on the BCPS CCA and routed on-board from J1-7 and J1-8. These signals are transient protected by CR45 and CR46. Resistor R108 sets the gain of the amplifier to that of the ratio shown near U48-6 and the scaled output can be measured at TP19. Instrumentation amplifiers U49, U50, and U51 and associated circuitry perform the same function for Batt2_Curr+, Raw1_Curr+, and Raw2_Curr+ from J1-6, J1-5, and J1-4 as U48 discussed previously. Raw1_Curr+ and Raw2_Curr+ represent the DC current sensed for the System1 and System2 power supplies. Batt1_Curr+ and Batt2_Curr+ represent the charging or discharging currents of the System1 or System2 batteries. D-A converter U56 creates test waveforms which are sent to both Marker Beacon1 (J3-18, J3-19) and Marker Beacon2 (J418, J4-19) for test purposes. The test waveform from the U56 D-A converter is low-pass filtered by op-amps U6:A and U6:B. Op-amps U6:C and U6:D, along with resistor network RN14, transform the ground-referenced test waveform to differential levels before exiting to the Marker Beacons. The ground-referenced test waveform is also fed back to the A-D converter (U16-10) and can be measured at TP29. Address decoding is accomplished by decoders U23, U21, and U18. The devices decoded include the U4 SDRAM, the U1 and U2 flash ROMs, the U3 NVRAM, the U25 and U20 UARTS, the U45 and U42 parallel port data (read), the U32 parallel port data (write), the U38 parallel port control, the U54 and U53 A-D/multiplexor control, the U43 and U44 configuration switches/digital inputs, and the U46 and U47 A-D converter data bus. The U8 microcontroller does not have an A0 address line so all external accesses are accomplished in a 16-bit wide (word) format. The address map for the RMS CCA can be found near decoder U23. 2-10 Rev.

MODEL 2130 MARKER BEACON 2.3.3 Local Control Unit (1A1) Simplified Theory of Operation Refer to Figure 2-3. The Local Control Unit (LCU) controls the normal operation of the Marker Beacon. All operational functions are performed by the LCU and are controlled by either front panel keyboard when in the local mode or by the Remote Maintenance Subsystem (RMS) through the parallel interface. The LCU is controlled by the Portable Maintenance Data Terminal (PMDT), Remote Control Status Unit (RCSU) or Remote Status Unit (RSU) through the RMS for all remote operator intervention or by the RMS for automatic restart. The LCU receives the alarm outputs from the installed Amplifier/ Monitor circuit card(s) and depending on the configuration of the system, uses the results of these signals to determine alarm status. If an alarm is detected, the LCU shuts down the system currently radiating and transfers to the standby system in accordance with the system configuration. The LCU also provides the ability to disable monitors and bypass alarms as required by the operator. The LCU provides +12V to the two possible synthesizer VCO circuits, the +12V to activate the transfer switch, and the transmit enable clock to the installed Amplifier/ Monitors. Status is reported by LED's visible to operator standing in front of the Marker, or through the RMS to the PMDT/RCSU/RSU. An alarm shutdown is reported to the RMS as well as indicated by an audible alarm. Figure 2-3 LCU Simplified Block Diagram 2.3.3.1 Local Control Unit (1A1) Block Diagram Theory Refer to Figure 2-3. 2.3.3.1.1 DC to DC Converter The LCU receives +12V from the two independent system power supplies and diode OR's the two sources to provide input power to a DC to DC converter which supplies all required voltages for the LCU. 2.3.3.1.2 Power Fail Detectors Each of the two independent +12V sources is monitored by a voltage comparator to monitor the health and availability of power from each of the sources. These signals are used to determine voting logic for the alarm registers and are reported back to the RMS via the parallel interface. Rev.

MODEL 2130 MARKER BEACON 2.3.3.1.3 Key Switch Registers Front panel switches are de-bounced and held in the Key Switch Registers pending processing by the LCU transfer state machines. Commands received from the RMS via the parallel interface also control the contents of the Key Switch Registers. The registers will hold the last command received until the LCU transfer state machine processes the command. 2.3.3.1.4 Parallel Interface The interface to the RMS is via a parallel data bus consisting of eight (8) data bits, an Address Command line, a Write Command line, and a Read Command line. The sequence to access internal registers within the LCU consist of the address being placed on the data bus followed by the strobing of the Address Command line to latch the address into the internal address register. This is followed by the Read Command line driven true to facilitate a read from the latched address. For a write command, the address is followed by the data to be written to the LCU followed by strobing the Write Command line. Alarm Configuration, Bypass Commands, Key Commands, and basic LCU configuration are some of the bits controlled by the RMS via the parallel interface. State machine Status, Power-fail Status, System Configuration bits (SCON), and Local/Remote status are some of the status bits that are readable by the RMS via the parallel interface. 2.3.3.1.5 1.8432MHz Oscillator/Divider Chains Refer to Figure 2-4. The LCU employs a 1.8432MHz crystal oscillator to produce all frequencies required by the design. The frequency is divided by 512 to produce 3600Hz used to produce the audible alarm tone and the Transmit On clocks driven back to the monitors. The signal is further divided by 8 to produce 450Hz used as the system clock within the design. This signal is divided by 45 to produce 10Hz used in the 20 second delay counter and the Key De-bounce circuits. Figure 2-4 1.8432 MHz Oscillator/Divider Chains 2-12 Rev.

MODEL 2130 MARKER BEACON 2.3.3.1.6 Positive Alarm Register This register receives the positive (high True) alarms from the two potential monitors within a system. Depending on the configuration of the alarm voting and bypass logic, the Alarm Register will report an alarm to the transfer state machines if reported by the enabled monitors. 2.3.3.1.7 Negative Alarm Register This register receives the negative (low True) alarms from the two potential monitors within a system. Depending on the configuration of the alarm voting and bypass logic, the Alarm Register will report an alarm to the transfer state machines if reported by the enabled monitors. 2.3.3.1.8 20 Second Delay Counter The 20 second delay counter is activated whenever the system initially powers up or a transmitter has been shut down without transferring to a standby system to ensure that the system will not radiate any signal for a period of 20 seconds following the shutdown. 2.3.3.1.9 LCU Transfer Control State Machine #1 and #2 and Discrete Controls The heart of the LCU is the two redundant transfer control state machines. These are configured by the RMS; receive key commands from the front panel or from the RMS, and process alarms reported by the monitors after being filtered by the Positive and Negative Alarm Registers. Once configured for on air, the state machines will drive out the required signals to enable the transmit on clocks (1_TX_ON_CLK, 2_TX_ON_CLK), enable the +12V power to the synthesizer VCO's (1_12VCO, 2_12VCO), and select the required system to be placed on the antenna (1_+12ANT_SW, 2_+12ANT_SW). With the redundant state machines, detection of an error assures that the system generating the error will be removed from the air. The LCU transfers to the standby system if configured to do so either immediately for a Hot Standby system or after a 20 second delay for a Cold Standby system. If further alarms are detected, the LCU transfer state machines will shut the standby transmitter down and block any further transmission for a minimum of 20 seconds. Restarts are under the control of the RMS. The LCU transfer control state machines report status back to the RMS indicating the state of the state machines, and any shutdowns that have occurred. The front panel LED's reflect the current state of the state machines. 2.3.3.1.10 LED Control Status is fed back to a local operator via the LED's on the front panel of the LCU. These reflect the state of the transmitters and the various alarms as reported by the monitors. 2.3.3.1.11 Audible Alarm If an alarm as reported by the monitors is detected that is not bypassed, the audible alarm is generated. The audible alarm can be reset by pressing the Alarm Silence button on the front panel. In local mode, the audible alarm is disabled. 2.3.3.2 Local Control Unit CCA (1A1A1) Detailed Theory of Operation Refer to Figure 11-14. The LCU controls the sequencing of the main and standby Marker Beacon transmitters according to alarm signals from the monitors. It displays the status of the station and accepts control input from a local operator. The LCU also provides status to and accepts control information from the PMDT or RCSU through the RMS parallel interface. The LCU circuit card consists primarily of two Field Programmable Gate Arrays (FPGA's), discrete control logic and digital interface circuitry. It also contains light emitting diodes (LEDs). 2.3.3.2.1 Power Supply The power for the LCU CCA comes from two separate sources of +12 VDC through Schottky rectifiers CR29 and CR30. The rectifiers isolate the two +12 VDC sources from each other and allow either to supply power to the board. The +12 VDC is converted to +3.3 VDC by a DC to DC converter, PS1. The +3.3 VDC supplies power for all the circuitry in the LCU. Rev. A April, 2005 2-13 This document contains proprietary information and such information may not be disclosed to others for any purposes without written permission from SELEX Sistemi Integrati Inc. MODEL 2130 MARKER BEACON Each of the two +12 VDC sources used to power the board are monitored by comparator U10. The two comparator circuits are identical, so the following discussion will explain the monitoring of the 1_+12 VDC supply. The +12 VDC supply voltage is reduced to approximately +2.7 VDC by a voltage divider network consisting of R33 and R37. This voltage is connected to the positive input of comparator U10A. The +3.3 VDC VCC supply is reduced to 2.18 VDC by another voltage divider network, R30 and R31. This voltage is connected to the negative input of U10A. When the +12 VDC supply is at a normal voltage, the positive input to U10A is higher than the negative input so the output of the comparator will be at a high logic level. Since the output of the comparator is an open collector, R32 is necessary to pull it high. When the voltage of the +12 VDC supply falls below approximately +9.60 VDC, the voltage at the positive input of U10A will fall below +2.18V and cause the output of U12A to go to a low logic level. 2.3.3.2.2 Pushbutton Switches and LED Display The LCU accepts control input from the operator through momentary contact pushbutton switches and presents status information for the Marker Beacon station through a series of light emitting diodes (LEDs). The pushbutton switch circuitry is implemented by using a pull up resistor to +3.3V to produce a high logic level and using a pushbutton switch to momentarily ground it to produce a low logic level. Switches that provide a toggling or sequencing function (where a multiple push would give a different result from a single push) are de-bounced by logic within the EPLDs (U1 and U3). For other switches, a repetitive contact or bounce will not have a noticeable affect. The board uses three different colors of LEDs: red, yellow, and green. Each of the three colors has a slightly different forward bias voltage and efficiency. Because of this, two different values of series resistor are used in order to create the same degree of perceived brightness. A lamp test pushbutton is implemented in the LCU in order to turn on all the LEDs to confirm their functionality. When the lamp test switch, S3, is pushed, logic within U1 and U3 causes all outputs to LEDs to be driven low, lighting the LEDs. 2.3.3.2.3 Parallel Interface The RMS communicates with the LCU and the Cabinet Interface Unit (CI) through an eight bit parallel bus interface. In order to keep the design of the peripheral (LCU or CI) simple, the RMS controls all the communication on the interface. The RMS reads and writes to the peripheral circuitry with no handshaking. The interface consists of an eight bit bidirectional address/data bus, an address strobe, a write strobe, and a read enable. In order to achieve sufficient noise immunity, the address strobe and the data write strobe are driven differentially through an RS-422 interface IC, U4. The remainder of the interface is driven to 3.3V CMOS logic levels. The parallel interface uses the following signals: Address/Data Bus The eight bit bi-directional address/data buss with multiplexed address. Address Strobe A differentially driven pulse from the RMS to latch address information into the peripheral. Data Write Strobe A differentially driven pulse from the RMS to write data to the peripheral. Data Read Enable A pulse from the RMS to enable data from the peripheral to be placed on the data bus. The RMS has the ability to read the status and control the operation of the Marker Beacon station through a parallel interface. Data transfer is accomplished by first placing an address on the bus and cycling the address strobe (asserting and then de-asserting the address strobe signal). The LCU latches and decodes the address within the EPLD's U1 and U3. For a read operation, the read enable is then asserted which tells the LCU circuitry to place the appropriate data on the data bus. For a write operation, the RMS places data on the data bus, then cycles the Data Write Strobe (asserting and de-asserting the write strobe signal.) The address decoding circuitry within the EPLD's decodes eight addresses, starting at (hexadecimal) 80. To buffer the EPLD's, a bus transceiver U21 is used on the data bus to provide CMOS logic thresholds to/from the parallel interface. 2-14 Rev.

MODEL 2130 MARKER BEACON Addr = 89 Bit 5 Bit 6 Bit 7 Write Reserved Reserved LOCPRN, LOCCLRN Read Reserved Reserved Reserved 2.3.3.2.4 Monitor Alarm Interface Circuitry In order to insure that a monitor alarm signal is communicated to the control logic, redundancy is incorporated into the monitor alarm signals. Each alarm signal is sent as two signals, one active high and the other active low. In the LCU, resistors are used to pull each of their signals to their active (alarm) state. This insures that an alarm condition will be sensed if there is an open in either alarm line. If an alarm line is shorted to its inactive (non-alarm) state, the other line will communicate an alarm condition. If the 1_INT_ALARM+ signal is disconnected, a resistor in RN3 will pull the input high resulting in an alarm condition being sent to the control logic in the EPLD U3. If the 1_INT_ALARM- signal is disconnected, a resistor in RN15 will pull the input to a low logic level. The output of buffer U17 will send a low level which will result in an alarm condition being sent to U22. HC logic devices are used to provide CMOS (mid rail) thresholds for the alarm inputs. 2.3.3.2.5 Station Control Logic The station control logic is duplicated in both U1 and U3. The logic responds to local operator control through the pushbutton switch inputs as well as remote control through the parallel interface. The local operator can perform the following functions: a. b. c. d. e. f. g. Specify which Marker transmitter is to be designated as main. Turn either transmitter ON and connect it to the antenna. Turn either transmitter ON and connect it to the load. Turn either transmitter OFF. Toggle the bypass state of either of the monitored signal sources (Integral, Standby). Silence the aural alarm (until the next event causes it to sound). Toggle the state of local control. When local control is set, input from the keypad is enabled. The following functions can be performed by the RMS through the parallel interface: a. b. c. d. e. Functions a-g listed above. Enable or disable the alarm signals from either one of the monitors. When a monitor's alarm signals are disabled, it is functionally equivalent to the monitor producing constant alarms. Set the "AND/OR" state of the alarm logic when it combines the alarm signals from Monitor 1 with the alarm signals from Monitor 2. When set to "AND", both monitors must provide an alarm from the same source to cause the station to transfer. When set to "OR", Monitor 1 signaling an alarm or Monitor 2 signaling an alarm will cause the station to transfer. Set the "Maintenance Alert" state. This lights the corresponding LED on the panel and sounds the aural alarm. Set the "Remote Control Fault" state. This lights the corresponding LED on the panel and sounds the aural alarm. In the alarm logic circuitry, the alarms from Monitor 1 alarm status are displayed on the panel. Similarly, the alarms from Monitor 2 alarm status are displayed on the panel. If a given monitor’s alarm signals are disabled by the RMS, it is equivalent to all of that monitor's alarm signals being asserted. The state of the AND/OR setting determines whether both or either of the Monitor 1 or Monitor 2 signals are required to produce a transfer condition. If one of the two +12V power fail logic signals from U10 goes active, the alarm logic will force an alarm condition for the monitor pair that is powered from the corresponding +12V supply. In order to avoid shutting the Marker Beacon station down, the alarm logic is forced to the AND state. This allows the other monitor to monitor the system. Rev. A April, 2005 2-17 This document contains proprietary information and such information may not be disclosed to others for any purposes without written permission from SELEX Sistemi Integrati Inc. MODEL 2130 MARKER BEACON The alarm signals from the monitors have already been given the appropriate transfer delay times within the monitors. This results in an immediate transfer when the combinatorial requirements of the alarm signals are met. When a transfer condition occurs, the present transmitter that is connected to the antenna system is taken off the air. The other transmitter is connected to the antenna system, and turned on (if it is not already on). If the transmitter, not designated as main connected to the antenna system when the transfer condition occurs, the control logic will enter the shutdown state and both transmitters are turned off. Once the control logic enters the shutdown state, no further transfer operations will take place until a local operator or the RMS turns one of the transmitters on and specifies that it is connected to the antenna system. The Station Control Logic controls which transmitter is connected to the antenna system by the status of the +12V ANT outputs. In order to insure the state of the antenna transfer relay, a status signal is returned from it. This signal is monitored by the RMS through the parallel interface at Bits 0 and 1 of address 83 (hex). 2.3.3.2.6 Aural Alarm An aural alarm is turned on when the system control logic senses an alarm condition as reported by the monitors. The frequency for the alarm is obtained from U3. It is the 1.832 MHZ divided by 512 which is 3600 Hz. The signal is also inverted by U3. The inverted and non-inverted 3600 Hz signals are both gated by U3. The two outputs of U3 provide a differential signal to drive piezoelectric alarm element LS1. The system control logic turns the alarm on by asserting the active low ~ALARM signal. When the ~ALARM signal is at an inactive or high logic level, the outputs of both U3 will be high which will result in no differential signal to drive the alarm. The level of the signal is adjusted by R43. R44 prevents the adjustment of R43 to result in a level which is too low. 2.3.3.2.7 System Configuration Inputs In order to reduce the amount of effort required to program various modules within the Marker for the proper configuration, there are eight logic signals that are sent from the RMS to each module to specify the system configuration. The configuration signals are readable by the RMS via hex address 86. The logic signals are produced by switches on the RMS. Isolation is provided in the event power is lost to the LCU. The resistors in RN9 pull the inputs to U1 to a high logic level if the configuration inputs are high. 2.3.3.2.8 Clock Oscillator and Divider Clock signals are necessary for the operation of the sequential circuitry within the two EPLDs U1 and U3. The output of a 1.8432 MHZ oscillator Y1 is sent to U3. U3 divides the oscillator frequency by 16384 to produce a 450 Hz clock signal. Within U3, the 450 Hz clock is divided by 45 to produce another 10 Hz clock. The 450 Hz clock and the 10 Hz clock are both used by U1 and U3. The divide by 512 output of U3 is used to provide 3600 Hz for the aural alarm for the LCU. 2.3.3.2.9 Reset and Watchdog Circuitry A reset circuit U9 is used to provide a reset signal to the LCU logic circuitry when it is powered up or in the event that the 3.3V power supply voltage falls below a threshold. The LCU control logic uses the reset to set the system control logic to a safe operational state. The alarm bypasses are turned off, the main transmitter is set to #1 and other settings within the logic are set to a default state. As long as the reset is asserted the transmitter off signals are asserted. When the reset returns to its non-asserted state, the LCU waits to be configured before any transmitter is turned on and is connected to the antenna. Immediately after reset, the RMS must update the control settings within the LCU since the default settings such as monitor enables, Hot Standby and the And/Or selection may not be desired. A pushbutton switch S14 allows the operator to manually reset the system through the LCU. R34 pulls the MR (pin 1) input to its inactive high state. When S14 is pushed, the Master Reset signal is asserted low causing U9 to generate a reset within the LCU at the same time the rest of the system is driven into a reset condition. A watchdog circuit within U9 monitors the internal 10 Hz clock and de-asserts the transmitter enable signals in the event that the clock oscillator or the clock dividing circuitry fails. The 10 Hz clock signal is connected to the WDI input of U9. If the clock fails to toggle for 1.6 seconds, the ~WDO output will go active. Logic within EPLD's U1 and U3 will then assert the ~OFF1 and ~OFF2 signals to the monitor which will then turn off both Marker Beacon transmitters. 2-18 Rev.

The Battery Charge Power Supply (BCPS) CCA distributes power, performs battery charging, and facilitates power monitoring in a single or dual Far Field Monitor (FFM) or Marker Beacon system. The BCPS CCA receives AC line power at terminal block TB1 and immediately routes it to a fused AC outlet via the same terminal block. AC current up for to two FFM / Marker Beacon pairs is measured via a single transformer while AC Voltage for up to two FFM / Marker Beacon pairs is measured by two separate transformers. The secondary of each AC Voltage sensing transformer shall light an AC_On indicator if AC is detected. The AC voltage secondary and the AC current secondary are routed to the J1 connector for measuring by the Remote Monitoring System (RMS). The FFM / Marker Beacon pairs are designated as System1 and System2 and are identical in operation. System1 consists of FFM1 and Marker Beacon1 while System2 is the FFM2 /Marker Beacon2 pair. Only System1 shall be discussed further. System1 AC power is fused, switched, and routed via terminal block TB1 to an external AC-DC power supply. The power supply furnishes +15 VDC back to the BCPS CCA via terminal block TB2. The +15VDC is current monitored, fused, and routed to Battery1 Charger / Changeover circuitry. A +12 VDC battery for System1 joins the Charger / Changeover circuitry via terminal block TB2. The Charger / Changeover circuitry monitors the battery voltage/current and switches to battery back-up power if AC power is no longer present. The Charger / Changeover circuitry also shuts off battery backup if the battery is near depletion to prevent permanent damage to the battery. A Battery1 disconnect switch is used for system power-down as well as battery fault testing. Battery1 indicators include both Batt1_Fault (the battery is not connected or an open cell condition) and On_Batt1 (AC power is no longer present). The output of the Battery1 Charger / Changeover circuitry is routed to two switches, one each for FFM1 and Marker Beacon1. An indicator for each DC output is lit if the corresponding switch is activated and DC power for each is routed to terminal block TB2. Figure 2-5 FFM / Marker Beacon BCPS Block Diagram Rev.

MODEL 2130 MARKER BEACON 2.3.4.3 Marker Beacon BCPS CCA Detailed Circuit Theory Refer to Figure 11-13. AC line, neutral, and earth enter via TB1-1, 2, and 3. The AC line is fused by F5 and routed to the external AC outlet on TB1-4. The AC neutral for the outlet is routed directly to TB1-5. AC earth for the outlet and both external power supplies PS1 and PS2 are connected directly to TB1-6, 10, and 13. Transformer T1 scales AC current detected for both System1 and System2 to its secondary where it is loaded by burden resistor R3 and transient protected by CR15 before routing to DB25 connector J1. The FFM / Marker Beacon pairs are designated as System1 and System2 and are identical in operation. System1 consists of FFM1 and Marker Beacon1 while System2 is the FFM2 /Marker Beacon2 pair. Only System1 shall be discussed further. The AC line after the transformer T1 primary is fused by F1 and switched by one side of DPDT switch S1. The output of S1 connects to the primary of voltage-sensing transformer T2, whose secondary scales the voltage before full-wave rectification by diodes CR3-6. This rectified voltage is transient protected by diode CR1 and filtered by capacitors C1 / C3 before routing to both connector J1 and diode CR54. Diode CR54 performs a diode-OR with the TESTAC1 voltage (more information later) before entering current-limiter U1. Current-limiter U1 and resistor R1 insure consistent brightness of LED CR13 regardless of AC voltage or TESTAC1 voltage levels. The AC neutral, after transformer T2 primary, is switched by the remaining side of the DPDT switch S1 before routing to TB1-9. An external AC-DC power supply connects to TB1-8, 9, and 10. The external AC-DC power supply converts AC voltage to +15VDC and connects back to TB2-9 and 6. The positive side of this DC supply (TB2-9 and labeled +15VIN1) is fused by F3 and routed to the Battery1 Charger / Changeover circuitry (more information later). The negative side of this DC supply (TB2-6) is routed through current-monitoring resistor R6. The Kelvin-type output connections of resistor R6 are transient-protected by CR19 before routing to connector J1. Battery1 connects to TB2-1 and 4 where it is reverse-voltage protected by diode CR12. The positive side of this +12 VDC battery (TB2-1 and labeled BATT1+) is switched by Batt1 Disconnect switch S3 before routing to the Battery1 Charger / Changeover circuitry (more information later). The negative side (TB2-4) flows through current-sensing resistor R4. The Kelvin-type output connections of resistor R4 are transient-protected by CR17 before routing to connector J1. Oscillator circuitry U8:A, C14, and R24 establish an 8192 Hz heartbeat for the battery fault testing of both Battery1 and Battery2. Inverters U8:C and U8:B buffer and invert the clock signals so that counter U7 and flip/flop U6:A change on the same edge. Counter U7 sets an overall time period of two seconds while AND gate U9 / U8:D presents a logic high to the U6:A-5 input for 32 milliseconds of the 2 second time period. The logic high is clocked through U6:A to both the gate of transistor Q4, shutting down charger U3, and to the gate of transistor Q11, placing a load of R30 and R31 on Battery1. If a battery is not connected, the load will cause a logic low to be clocked through R81 / U6:B-9, turning on transistor Q5 and Batt1_Fault indicator CR27. In summary, once every 2 seconds for 32 milliseconds, a load is placed on the battery to check for its presence. Charger U3 is a constant voltage / constant current integrated circuit whose final battery voltage is set by resistors R10, R11, R12, and R13. Charger U3 switches the +15VIN1 through transistors Q1:A, Q2, Q3, diode CR11, inductor L2, and resistor R8 to Battery1 in a switch-mode manner. Inductor L2 and resistor R8 establish the charger current through feedback resistors R16 and R17. The switch-mode frequency of charger U3 is set by resistor R18 and capacitor C11. More information on the charger U3 integrated circuit is available at the manufacturer’s web site. Charger U3 also routes +15VIN1 through transistors Q1:A and Q1:B to VSUM1 while +15VIN1 is present. If +15VIN1 is no longer present, Battery1 is switched though transistors Q10:A and Q10:B to this same point labeled VSUM1. VSUM1 is filtered by capacitors C32, C34, C42, and inductor L4 before routing to switches S5 and S6. If switches S5 and S6 are closed, VSUM1 is routed to connector J1-11 and 13 and lights MRKR1_DC and FFM1_DC indicators CR21 and CR22. +15VIN1 also routes to voltage divider R44 and R45 which sets the “on battery” trip point of comparator U5:B, U5:C, and 2-20 Rev. A April, 2005 This document contains proprietary information and such information may not be disclosed to others for any purposes without written permission from SELEX Sistemi Integrati Inc. MODEL 2130 MARKER BEACON U5:D. As long as the +15VIN1 level is above the trip point set by the voltage divider and the +3.3VREF from regulator U4, the OR’d output of U5:B, U5:C, and U5:D will be pulled high through R83. This high output will simultaneously keep On_Batt1 indicator CR29 off and transistor Q13 on. Transistor Q13 being on pulls the output of comparator U5:A low through diode CR80, which in turn keeps battery switch transistors Q12, Q10:A, and Q10:B off. In summary, if +15VIN1 remains above the “on battery” trip point, the On_Batt1 indicator and battery switch transistors Q10:A and Q10:B are all off. If +15VIN1 drops below the “on battery” trip point, the On_Batt1 indicator CR29 is lighted with current regulated by resistor R47 and zener diode CR85. Transistors Q10:A and Q10:B will then be turned on (switching Batt1 into VSUM1) until the Batt1 voltage drops below the “battery too low” trip point established by voltage divider R28 / R27 and +3.3VREF on the inputs of comparator U5:A. Once Batt1 voltage falls below the “battery too low” trip point, the output of comparator U5:A will go low and shut off transistors Q10:A and Q10:B; thus removing all power to the FFM1 and Marker Beacon1. This is done to prevent complete discharge of a battery, which might cause permanent damage. Regulator IC U4 creates +5VREF from the diode OR’d supply VALWAYS which is a combination of +15VIN1, +15VIN2, Batt1, and Batt2 through diodes CR56, CR57, CR67, and CR68. As long as power is supplied in some way to the board, VALWAYS and +5VREF exist. Another diode OR’d supply named VSUM1N2 is created by diodes CR25 and CR26 to power the oscillator and reset circuitry of U6, U7, U8, and U10. As long as VSUM1 or VSUM2 are active, the battery fault testing will continue. Charging of Battery1 can be manually disabled by connecting jumper strap JP1A between JP1-1 and JP1-2. Disabling BCPS1 in this manner shuts off charger U3 and prevents the lighting of on-board Batt1_Fault indicator CR27 and On_Batt1 indicator CR29 through diodes CR44 and CR45 as well as off-board indicators On_Batt1 J1-1 and Batt1_Fault J1-3 through diodes CR81 and CR46. Disabling BCPS1 will not allow lighting of On_Batt1 indicator CR29 and Batt1_Fault indicator CR27 even during a lamp test (TEST* active low). The TEST* signal from connector J1-14 is the means by which an external controller may light all indicators and stop battery fault testing. TEST* is filtered by FL3 and transient protected by diode CR42. TEST* connects to the cathode side of diodes CR51, CR52, CR53, and CR23. When TEST* is low, the On_Batt1 indicator CR29 is lit through CR51 assuming the BCPS1 disable jumper at JP1 is not in place. Also, reset inverter U8:F is pulled low through diode CR52 causing U6:B to turn on transistor Q5 and Batt1_Fault indicator CR27 (again assuming the BCPS1 disable jumper at JP1 is not in place). While Test* is low, transistor Q21 will be turned on; lighting FFM2_DC indicator CR33 through diode CR62, lighting MKR2_DC indicator CR32 through diode CR63, lighting FFM1_DC indicator CR22 through diode CR64, lighting MKR1_DC indicator CR21 through diode CR65, lighting SYS1_AC indicator CR13 through diode CR66, and lighting SYS2_AC indicator CR14 through diode CR24. Finally, current through diode CR90 will light Batt1_Fault indicator CR27 and On_Batt1 indicator CR29 in the event BCPS1 is not powered (again assuming the BCPS1 disable jumper at JP1 is not in place). Signal SHDN1* is the means by which an external controller may stop charging of the battery. SHDN1* enters via connector J1-5, is filtered by inductor FL1 / capacitor C40, transient protected by diode CR41, and connects to charger U3. A low level on the SHDN1* signal disables charger U3.

MODEL 2130 MARKER BEACON 5.4 Special Maintenance Procedures 5.4.1 Equipment Cleaning and Inspection a. b. c. d. e. f. g. Antenna system, including antennas and towers. Check all insulators. Inspect and repair all connectors. Inspect the antenna mounting hardware for loose or broken supporting hardware such as nuts, bolts rivets and welds. Inspect the monitor probe for visual damage or deterioration. Clean any rusted areas, and apply rust inhibiting paint as required. Buildings. Inspect buildings for deterioration, both inside and out. Check condition of building paint and for signs of leaking. Grounds. Check vegetation control, cable marker signs, fences and gates. Air Filters. Inspect and replace as required all building and equipment air filters. Motors. Inspect all motors to determine that they are not overheating. Lubricate as required. Battery systems. Inspect for proper ventilation. Clean any battery corrosion. Safety signs. Inspect the site and install signs as required. 5.4.2 Backup Battery Power Check. NOTE Notify Air Traffic Control of the intended check. This procedure takes about one hour to complete, and a possibility exists that an equipment shutdown or transfer to standby could occur. Since the system specialist is most familiar with the facility, it is left up to the specialist to decide whether to issue a NOTAM. a. b. c. d. With the PMDT note that equipment parameters are normal. Locate the AC power circuit breaker for the Marker Beacon. Using a wrist watch or clock, note the current time and switch the equipment AC circuit breaker to the OFF position. For a period of one hour; observe that all equipment monitored parameters remain within normal limits and that no alarms occur (except for a possible maintenance alert for loss of commercial power). 5.4.3 RF Cable Inspection a. b. The following test is performed with the facility operating normally except when inspecting around the antenna, which will require a shutdown. From the Marker Beacon transmitter and monitor to the antenna, visually inspect the RF transmission cable for cracks, loose or failed tie wraps, deteriorated weather proofing tape (if used) and sealant.. Inspect for sun or wind damage to RF cables mounted outside. Also for RF connectors not waterproofed and sealed, hand check the cable and connectors for tightness. 5.4.4 Measure RF Cable Insulation Resistance 5.4.4.1 Test Equipment Required An appropriate insulation tester, such as a 500 volt megger. 5-8 Rev. A April, 2005 This document contains proprietary information and such information may not be disclosed to others for any purposes without written permission from SELEX Sistemi Integrati Inc. MODEL 2130 MARKER BEACON 5.4.4.2 Procedure a. b. A facility shutdown is required. Issue a NOTAM. Disconnect the transmission line under test at both ends. CAUTION Megging transmission lines connected to antennas or other components may cause damage to equipment. c. d. e. Connect the insulation tester between the center conductor and the shield. Operate the tester in accordance with its instructions. Measure and compare the insulation resistance against Table 3-1. If the measured insulation resistance is less than the applicable tolerance, corrective action must be taken. If significant change is found from the previous readings, corrective action should be initiated to prevent further deterioration of the cable. NOTE If any cable measures less than infinite insulation resistance, especially new lines or those that previously measured infinity, consider corrective action even though the measurement is within prescribed tolerances. f. Restore the Marker to Normal condition. 5.4.5 Measure RF Cable DC Resistance. NOTE High DC resistance in RF lines with connectors attached usually indicates a faulted connector damage to the shield and/or center conductor. Also moisture within a cable and/or RF connector may result in corrosion, with a resulting high dc resistance path. 5.4.5.1 Test Equipment required An appropriate DVM with the capability to measure low DC resistance in the order of 1 to 5 ohms. 5.4.5.2 Procedure a. b. c. d. e. A facility shutdown is required. Issue a NOTAM. Disconnect the transmission line under test at both ends. Connect the insulation tester between the center conductors at both ends of the cable. Measure the dc path resistance and compare against Table 3-1. Connect the insulation tester between the shields at both ends of the cable. Measure the dc path resistance and compare against Table 3-1. Restore the Marker Beacon facility to normal. NOTE The measured values and Table 3-1 tolerances are to be used as a guide. This is a point at which maintenance action should be initiated to prevent further deterioration of the RF cable or quality of service. Exceeding this tolerance does not indicate that a facility should be removed from service. Rev.

Required test equipment is defined and packing instructions are included in this section. 6.2 Test Equipment Required Table 1-3 lists the test equipment and associated characteristics required to maintain the Marker Beacon system. 6.3 Onsite Corrective Maintenance The following paragraph provides general troubleshooting information. 6.3.1 General Troubleshooting Information a. b. c. Identify the symptom. List the symptoms that you find or a field technician describes. If someone else describes the symptoms to you, check the symptoms yourself or have that person demonstrate the symptoms to make sure the problem is not an operator error. Do a careful visual inspection of the suspected assembly, including the following suggestions. 1. 2. 3. 4. d. Check for signs of excessive heat. Check that all integrated circuits (ICs) are firmly seated in their sockets and that the ICs have no bent pins. Check that printed circuit board edge connectors are clean and seated fully. Check the ribbon-cable connectors. Check the power supplies. Power supplies are a very common source of problems. Low voltage or excessive ripple may make it appear that an IC is bad. Rev.

INSTALLATION, INTEGRATION AND CHECKOUT 8.1 Introduction This section contains the information required to install the equipment, inspect the installation, perform startup and preliminary testing procedures, and perform an installation verification test. 8.2 Site Information The Marker Beacons are located along the extended runway centerline to provide a rough indication of an aircraft's distance from the runway threshold, and to indicate significant points along an instrument approach path. An Outer Marker is typically located 4 nautical miles from the runway threshold; this location normally coincides with the point on the Marker Beacon approach at which the glide slope altitude equals the intercept altitude. A Middle Marker is typically located 3500 feet from the runway threshold; this location normally coincides with the point on the glide path at which the decision height (DH) is located for Category I operations--200 feet above the touchdown zone elevation. A typical Marker Beacon site plan is illustrated in Figure 8-1. This illustration shows the shelter and tower foundation locations, trenching details, and site preparation requirements. The terrain around the Marker Beacon site is to be graded to the specifications of FAA Order 6750.16B, Siting Criteria for Instrument Landing Systems, or as determined by the siting engineer. 8.3 Unpacking and Repacking Packing cases are to be handled and opened with care to avoid damage to electronics components. Be certain all fasteners, supports, and tie-downs have been removed before attempting to remove the units. Inspect all items for shipping damage and check against the packing slip to ensure complete shipment. Check the packing slip against Table 1-2. 8.4 Input Requirement Summary Refer to Table 1-1 for input power requirements. 8.5 Installation Procedures 8.5.1 Installation Test Equipment Refer to Table 1-3 for a list of test equipment required for installation.

MODEL 2130 MARKER BEACON 8.8 USB-Serial Driver Installation The PMDT interface on the 2130 MB RMS CCA is implemented using USB-Serial converter circuitry, based on the FTDI FT232BM IC. When the navaid is powered up, and the USB cable is connected to the PMDT computer, Windows should automatically detect the new USB device and install the appropriate driver, activating the new COM port. In the event that the driver isn’t automatically installed, the following procedure should be used. a. Locate the FTDI USB Driver. The driver is typically copied to the same directory that the PMDT.EXE file is located (ie. C:\Program Files\SELEX SI\PMDT\FTDI USB Driver\*.*. Alternatively, the driver can be downloaded from FTDI’s website: www.FTDIChip.com. Note that only the VCP type of driver for the FT232BM device should be used. b. When Windows detects the new USB device and prompts for the proper driver, select “Install from a list or specific location” option and press Next. c. Select only the “Include this location in the search” option and browse to locate the folder containing the driver (See step #1 above). Then press Next to install the driver. 8-12 Rev.

MODEL 2130 MARKER BEACON d. The driver will be installed, assigning the USB port to an available COM port. Press Finish to close the Hardware Installation Wizard. e. To use this serial port for the PMDT, start the PMDT application. f. Select System>>PMDT Setup and select the USB Serial Port as the Navaid Direct COM Port. 8.8.1 USB-Serial COM Port Notes The user should be familiar with the following operational notes related to using the USB-Serial COM Port. a. The USB-Serial Port is only active in the PMDT PC while the USB cable is connected between the PMDT and the navaid, and the navaids is powered up. Powering down the system, or removing the cable will remove the USB COM Port. If this is done while logged into the navaid, the user must Logout/Disconnect in the PMDT, and wait for the disconnect to be finalized. When the USB-Serial Port is re-activated (by either powering up the navaid, or reconnecting the cable) then the user can once again login to the navaid with the System>>Connect>>Navaid>>Direct menu option. b. Changing to another USB port on the PC could cause the USB driver to be assigned to another COM port. The currently active USB-Serial COM Port can always be determined and selected with the Navaid Direct COM Port setting in the PMDT’s System>>PMDT Setup screen. To simplify this connection, always use the same USB port on the PMDT computer for the PMDT-navaid link. Rev.
