FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 I-1SECTION I GENERAL INFORMATION 1.1 INTRODUCTION This document contains installation data and specifications about the FreeFlight Systems FDL-978-TX Universal Access Transmitter (UAT) Automatic Dependent Surveillance – Broadcast (ADS-B) Transmitter and associated TC-978 Controller for interfacing to the FDL-978-TX. The FDL-978-TX is a UAT equipment class B1/B1S 978MHz Transmitter that meets TSO-C154c requirements and the minimum operational performance standards in RTCA/DO-282B. 1.2 GENERAL SYSTEM DESCRIPTION The FDL-978-TX is designed to share aircraft position, velocity, and other flight data with other aircraft and ground station equipment. The FDL-978-TX satisfies the TSO-C154c requirements and the RTCA/DO-282B MOPS for UAT ADS-B class B1/B1S equipment. The FDL-978-TX collects position, velocity, and other aircraft information from an aircraft GPS, pressure altitude sensor, and pilot interface controller and transmits this data out once per second. The GPS data, pressure altitude data, and pilot control inputs are received by the FDL-978-TX through configurable RS-232/422/485 serial, ARINC 429 serial, and/or discrete interfaces. Status information about the FDL-978-TX health and state are output on the configured serial links and/or discrete signals for display to the pilot. Figure 1 shows a block diagram of a typical FDL-978-TX installation. This installation shows the TC-978 Front Panel Controller, the FDL-978-TX Transmitter, two UAT antennas, a GPS/WAAS sensor, and a GPS antenna. The GPS sensor can be an existing aircraft GPS source if it meets the interface requirements of the FDL-978-TX (ARINC 743A (ARINC 429) or FFS Navigation Interface Protocol (RS-232 or RS-422)). The TC-978 Controller contains an ETSO-C88a certified pressure altitude encoder and a RS-232 serial output to share the altitude encoder data with other devices such as a transponder. Additionally, an Air Data System or Pressure Altitude Sensor can optionally be interfaced to the FDL-978-TX to provide pressure altitude, altitude rate, and true airspeed if it meets the interface requirements of the FDL-978-TX. If an optional ADS or Altitude Sensor is configured with the FDL-978-TX, the TC-978 Controller will display the optional sensor altitude and output the optional altitude data on its RS-232 serial output. Note that the Transponder and the FDL-978-TX must share the same pressure altitude sensor data. The installation diagram also shows an optional diplexer installation so that antennas can be shared between a Transponder (1090MHz) and the FDL-978-TX Transmitter. The system can also be installed with a single UAT antenna in installations where the FAA does not require antenna diversity.

FD-978-TX Transmitter The FDL-978-TX is the main component of the FreeFlight UAT ADS-B Transmitter System. The FDL-978-TX has a DB-44 female connector, a USB micro-AB maintenance connector, and two TNC UAT antenna connectors. The FDL-978-TX contains a UAT Transmitter with top and bottom antenna outputs, four status LEDs, a controller interface, configurable GPS input interface, configurable Air Data/Altitude input interface, configurable Display output interface, Discrete inputs/outputs, Maintenance interface, and a Personality Module interface. A. UAT Transmitter The transmitter has top and bottom antenna outputs that can be configured to use the top only, bottom only, or both (diversity). B. Status LEDs Four status LEDs (UAT, GPS, UAT TX, and UAT RX(future use)) indicate the operational status of the FDL-978-TX. C. Controller Interface The FDL-978-TX has a TC-978 controller interface that provides low voltage power, system on/off discrete control, and a communication interface on serial port 3. The system can be configured through the controller interface. D. GPS Input The FDL-978-TX can connect to a FFS navigation protocol GPS (1201) through an RS-232 serial port or ARINC 743A compatible GPS (1203) through an ARINC 429 bus. E. Altitude/Air Data Input The FDL-978-TX can connect to an Altitude/Air Data Sensor through an RS-232 serial port or ARINC 429 bus and/or output encoded altitude on a serial output. F. Display Output The FDL-978-TX can provide ownship traffic data through a RS-232/RS-422 serial port. G. Discrete Inputs/Outputs The FDL-978-TX has six discrete inputs and two discrete outputs. H. Maintenance Interface The FDL-978-TX has a USB micro-AB serial port connector that can be used to update system software, check status, test the system, and configure the system. I. Personality Module Interface The FDL-978-TX has a personality module interface to retrieve configuration settings if the FDL-978-TX is replaced in the aircraft. 1.2.2 TC-978 Front Panel Controller Figure 5. TC-978 Controller
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 I-4The TC-978 Controller is the FDL-978-TX control and status interface. The controller has a DB-9 connector for electrical interface and a static pressure port. The TC-978 contains a LCD display with controls, a built in Altitude Encoder, low voltage input power interface, FDL-978-TX serial interface, remote on/off power control, and serial altitude output. A. Display and Controls The controller has an LCD status display, an Ident button, a VFR button, FN (function) button, ENT (enter) button, Mode knob, and Code entry knob. B. Altitude Encoder The controller has a built-in altitude encoder to measure pressure altitude. C. Input Power The controller receives low-voltage power from the FDL-978-TX. D. Serial Interface A two-wire data link is used to connect the TC-978 to the FDL-978-TX. E. Remote On/Off System on/off power is controlled with the mode knob. F. Altitude Output Pressure altitude data is output on an RS-232 serial port. 1.2.3 UAT Antenna Requirements The FDL-978-TX requires a TSO-C66, C74, C112, or C154 UHF antenna. Ensure that the antenna is a 50Ω antenna with a VSWR < 1.7:1 at 978 MHz. The Comant CI-101 and RA Miller AV-22 ball antennas and the Comant CI-105 blade antenna meet these requirements. In Class B1 ADS-B equipment (TSO-C154c) installations, antenna diversity (meaning a top and bottom antenna) is required. In Class B1S (single antenna) installations only one antenna (top or bottom) is used.

FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 II-1SECTION II INSTALLATION 2.1 GENERAL This section provides general information for installing the FDL-978-TX and TC-978 into an aircraft. This section contains mounting dimensions, pin outs, and interface details pertaining to installation. Adherence to these installation procedures and information will assure satisfactory system performance. 2.2 UNPACKING AND INSPECTING EQUIPMENT Exercise care when unpacking each item. Visually inspect each item for evidence of damage incurred during shipment. If a damage claim must be filed, save the shipping container to substantiate the claim. When all equipment and the installation kit have been inspected, save the packing material and container in case the unit is to be stored or reshipped. See paragraph 1.4 for equipment and optional parts supplied. 2.3 EQUIPMENT MOUNTING 2.3.1 TC-978 Mounting The TC-978 controller must be mounted rigidly in the aircraft panel. The controller can be mounted in the ultra compact mounting hole or in a conventional 57mm (2¼ inch) instrument cut-out. The following installation procedure should be followed, remembering to allow adequate space for installation of cables and connectors. • Select a position in the panel that is not too close to any high external heat source. (The TC-978 is not a significant heat source itself). • Avoid sharp bends and placing the cables too near to the aircraft control cables. If using a 57mm instrument cut-out, first clip the two mounting adapters to the controller. The controller should then be mounted using the four LONG screws provided. If using the FFS compact cutout, you do not need the mounting adapters. The controller should be mounted using the four SHORT screws provided. If alternate screws are required, please note that the mounting thread in each case is 4-40. Figure 6. TC-978-TX Dimensions 2.3.2 FDL-978-TX Mounting The FDL-978-TX Transmitter is designed to be mounted in any convenient location in the cockpit, the cabin, or an avionics bay.
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 II-2The following installation procedure should be followed, remembering to allow adequate space for installation of cables and connectors. • Select a position in the aircraft that is not too close to any high external heat source. (The FDL-978-TX is not a significant heat source itself). • Avoid sharp bends and placing the cables too near to the aircraft control cables. • Secure the FDL-978-TX on a flat surface according to the FDL-978-TX mounting requirements illustrated below in Figure 7 and in the installation drawing in Appendix D. Figure 7. FDL-978-TX Mounting Dimensions 2.4 COOLING REQUIREMENTS The FDL-978-TX and TC-978 meet all TSO requirements without forced air cooling. While each individual unit does not require forced air cooling, the combined heat load of several units operating in a typical avionics location may significantly degrade the reliability of avionics if provisions for cooling are not incorporated in the initial installation. Failure to provide adequate cooling may lead to increased avionics maintenance costs and may void the FreeFlight Systems Warranty.

Power input resides on the following pins: Power Input PIN SIGNAL ELECTRICAL I/O DESCRIPTION J1-1 Vin 10-40 VDC Pwr Aircraft Power Input J1-16 Vin 10-40 VDC Pwr Aircraft Power Input J1-17 RTRN Ground Gnd Aircraft Power Return J1-31 RTRN Ground Gnd Aircraft Power Return 2.6.2 Personality Module Installation specific configuration information is stored in three separate non-volatile memories in a properly installed system: • The Personality Module (PM), which is connected to the aircraft connector mated with J1 of the FDL-978-TX, contains the Master configuration that is used by the FDL-978-TX to configure the system. • The TC-978 Controller contains a Back-up configuration that is used by the FDL-978-TX to configure the system only when the Personality Module is not installed. • The FDL-978-TX Transmitter contains a Local configuration copy that is used immediately after power-up to start the system and is synchronized with the PM Master configuration or the controller Back-up configuration if the PM is not installed. The Personality Module (PM) eliminates the need to set-up the installation configuration again if a new FDL-978-TX transmitter or a new TC-978 controller is installed. The Master configuration in the PM is extracted by the FDL-978-TX and used to update the TC-978 Controller Back-up configuration and FDL-978-TX Local configuration if different than the PM Master configuration. The PM should be installed in the aircraft but the system will continue to function correctly if the PM malfunctions. If the PM malfunctions, the TC-978 Back-up installation configuration will be transferred to the FDL-978-TX and the FDL-978-TX will update its Local configuration if different. If a new TC-978 controller is installed in a system with a malfunctioning PM then the configuration information must be re-configured. The PM has no lightning protection so the wire length between the PM and the Power and I/O connector must be less than 4”. The PM connection is on the following pins: Personality Module Interface PIN SIGNAL ELECTRICAL I/O DESCRIPTION J1-14 Vpm 3.0 -3.6 VDC O Personality Module Power Output J1-30 GND Ground Gnd Personality Module Power Return J1-43 CLK_PM I2C I Personality Module Clock J1-44 DATA_PM I2C I/O Personality Module Data

The following table describes the LED states that can be observed: NAME DESCRIPTION STATUS UAT System Status (RED) ON UAT failure. Troubleshoot system. OFF UAT is operating normally. GPS GPS Status (GREEN) Flashing GPS is acquiring satellites and determining position. ON GPS has acquired satellites and is operating normally. OFF GPS is not communicating or has failed. TX UAT Transmit (GREEN) Blink ON Blinks ON when ADS-B data is transmitted (once per second) OFF No UAT transmissions RX UAT Receive (GREEN) OFF No UAT receptions (UAT transmitter has no receiver so this is the normal condition) 2.6.4 Controller Interface Low voltage power (+7 Volts DC), a system ON/OFF discrete control, and serial communication (RS-485 or RS-232) on serial port 3 is provided through the J1 Power and I/O connector as the controller interface. Serial port 3 is a single communication port that can be electrically interfaced via RS-232 or RS-485. For the current FDL-978-TX this interface is intended for use with the TC-978 Controller. The TC-978 Controller uses the serial port 3 RS-485 pins (J1-20 & J1-28) and does not use serial port 3 RS-232 pins (J1-23 & J1-24). Future controllers may use the serial port 3 RS-232 pin interface rather than the RS-485 interface. The controller interface connections are as follows: Controller Interface PIN SIGNAL ELECTRICAL I/O DESCRIPTION J1-18 Vcp +7 VDC O TC-978 Controller Power Output J1-2 GND Ground Gnd TC-978 Controller Power Return J1-32 REM ON Open/Ground I Remote Power Control (Ground: ON, Open: OFF) J1-20 TRxD3+ RS-485 I/O Serial Port 3 RS-485 Data+ J1-21 TRxD3- RS-485 I/O Serial Port 3 RS-485 Data- J1-23 232 RxD3 RS-232 I Serial Port 3 RS-232 Data In (Not used with TC-978) J1-24 232 TxD3 RS-232 O Serial Port 3 RS-232 Data Out (Not used with TC-978) 2.6.5 Physical Serial Interfaces There are a total of five physical serial interfaces available on the FDL-978-TX: Three UART style Serial Port interfaces and two ARINC 429 Input interfaces. These physical serial interfaces are available for connecting to four different functional interfaces: • GPS Input o Serial Port: “GPS-FreeFlight” or
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 II-6o ARINC: “GPS” • Altitude/Air Data Input o Serial Port: “Altitude Encoder” or “ADC” o ARINC: “ADC” • Altitude Encoder Output o Serial Port: “Encoded Altitude” • Display Output o Serial Port: “TIS/FIS” or “ADS-B Pass Thru” Each of the four functional interfaces can be configured to one and only one physical serial interface. Only one of each of the functional interfaces is handled by the FDL-978-TX All physical serial interfaces are configured to functional interfaces in Configuration Mode. If two or more physical serial interfaces are configured to the same functional interface only one physical serial interface is programmed by the FDL-978-TX to use the functional interface and all other configurations of the same functional interface are ignored. The order of precedence used by the FDL-978-TX for a functional interface is as follows: • ARINC 429 physical interface takes precedence over UART physical interface • Lowest port/channel number takes precedence over higher port/channel number For example, if Serial Port 2 Input is configured to “GPS-FreeFlight” and ARINC 429 Input Channel 1 is configured to “GPS” then the FDL-978-TX uses ARINC 429 Input Channel 1 as the GPS Input functional interface and the Serial Port 2 Input configuration is ignored. As another example, if ARINC 429 Input Channel 2 and ARINC 429 Input Channel 1 are both configured to “GPS” then the FDL-978-TX uses ARINC 429 Input Channel 1 for the GPS Input functional interface and the ARINC 429 Input Channel 2 configuration is ignored. Additionally, only one functional interface type can be configured for each of the two UART style Serial Port (2 & 6) physical serial interfaces that have bi-directional capability. If both the input and the output of Serial Port 2 or 6 are configured then the order of precedence is as follows: • GPS Input • Altitude/Air Data Input • Altitude Encoder Output • Display Output For example, if Serial Port 2 Input is configured to ”GPS-FreeFlight” and Serial Port 2 Output is configured to “TIS/FIS” then the FDL-978-TX uses Serial Port 2 as the GPS Input functional interface and the Serial Port 2 Output configuration is ignored. 2.6.5.1 Serial Ports - RS-232 / RS-422 / RS-485 Three UART style (Serial Port) physical serial interfaces are available on the FDL-978-TX. The three Serial Ports available are described below: • Serial Port 2 – Bi-directional (transmit and receive) capability and can interface via either RS-232 or RS-485. Typically configured as the GPS Input functional interface but can also be configured as a Display Output, Altitude/Air Data Input, Altitude Encoder Output • Serial Port 4 – RS-232 receive-only capability. Typically configured as the Altitude/Air Data Input functional interface but can also be configured as a GPS Input. • Serial Port 6 – RS-422 bi-directional (transmit and receive) capability. Typically configured as the Display Output functional interface but can also be configured as a GPS Input, Altitude/Air Data Input, or Altitude Encoder Output.

The ARINC 429 Input channels are 429 IN 1 and 429 IN 2. The FDL-978-TX has one ARINC 429 Output that is reserved for future use and is not currently configurable. Both ARINC channels can be configured as either high-speed or low-speed. The ARINC output channel is reserved for future use. The ARINC 429 Input channels can be configured as either of the following: • Air Data Computer Input – accepts the following ARINC labels: LABEL DESCRIPTION 203 Pressure Altitude 210 Airspeed 212 Altitude Rate • GPS Input – accepts the following ARINC 743A labels: LABEL DESCRIPTION 110 Latitude Coarse 120 Latitude Fine 111 Longitude Coarse 121 Longitude Fine 370 Altitude (HAE) 166 North/South Velocity 174 East/West Velocity 112 Groundspeed 103 True Track Angle 165 Vertical Speed 260 Date 150 UTC 130 Horizontal Integrity Limit (HIL) 133 Vertical integrity Limit (VIL) 247 Horizontal Figure of Merit (HFOM) 136 Vertical Figure of Merit (VFOM) 273 Sensor Status

All six discrete inputs are intended to be connected to open/ground type switches if used. All discrete inputs default to the open condition if not connected. The discrete input pin connections are as follows: Discrete Inputs PIN SIGNAL ELECTRICAL I/O DESCRIPTION J1-12 TRAF STDBY Open/Ground I Traffic Standby J1-13 ANON MODE Open/Ground I Anonymous Mode J1-15 TRAF TEST Open/Ground I Traffic Test J1-22 GND Ground Gnd Ground Reference J1-26 TCAS RA ACT Open/Ground I TCAS Resolution Advisory Active In (Active low) J1-27 AIR/GRND Open/Ground I Air/Ground In (Squat Switch - configurable) J1-42 CDTI OPER Open/Ground I CDTI Operational 2.6.6.1 Air/Ground Input The Air/Ground discrete input can be connected to an open/ground squat switch or other Air/Ground discrete indication. The Air/Ground discrete is configurable to be either Not Connected, High when Airborne, or Low (ground) when Airborne. The FDL-978-TX automatically determines air/ground state based on several factors: Emitter Category type, Airspeed (if available), groundspeed, and Air/Ground discrete input. 2.6.6.2 Anonymous Mode Input The anonymous mode discrete input determines if the FDL-978-TX is in anonymous address mode. If the anonymous mode input is tied to ground the FDL-78-TX will be in anonymous mode and transmit a randomly generated anonymous address in the ADS-B message in place of the ICAO address. Even if anonymous mode is set, the FDL-978-TX will transmit the configured Mode S (ICAO) address under the following conditions: • During the first two minutes after initial power-up • When the squawk code is set to anything other than 1200 2.6.6.3 CDTI Operational Input The CDTI Operational Input is reserved for future use to indicate the operational status of an on-board TCAS. A ground will indicate the TCAS is installed and operational, while an open will indicate the TCAS is not installed or operational. This discrete should be left open. 2.6.6.4 TCAS Resolution Advisory Active Input The TCAS Resolution Advisory Active Input is reserved for future use to indicate the status of any resolution advisories from an on-board TCAS. A ground will indicate a TCAS resolution advisory is active, while an open will indicate no TCAS resolution advisories are active. This discrete should be left open.

This discrete should be left open. 2.6.6.6 Traffic Test Input The Traffic Test Input is reserved for future use to indicate the traffic test status of a 429 traffic display. This discrete should be left open. 2.6.7 Discrete Output Two discrete outputs are available to provide UAT status and operational information to other equipment. The two discrete output connection pins are as follows: Discrete Outputs PIN SIGNAL ELECTRICAL I/O DESCRIPTION J1-28 TX SUPPRESS Vin -1.5V O L-Band Suppression Bus J1-41 UAT STATUS Open/Ground O ADS-B Status 2.6.7.1 UAT Status Output The UAT Status output is an active low, open collector output capable of sinking a maximum of 100 mA. The UAT status output indicates a UAT system failure when grounded. Note that UAT system failure includes the loss of valid GPS data from the external GPS. 2.6.8 TX Suppression Output The TX Suppress output is for suppressing other L-band equipment during UAT transmissions. TX Suppress outputs a high (Vin – 1.5 V) only during UAT ADS-B message transmissions and is low otherwise. The TX Suppress output is typically connected to the transponder suppression bus. 2.6.9 Time Mark Input (PPS) The Time Mark Input is an RS-422 differential pair for the one pulse-per-second (PPS) input from a GPS like the FFS 1201 or FFS 1203/1203C. The Time Mark input from a GPS provides the timing synchronization for sending ADS-B messages.

Do NOT connect to aircraft input power. 2.8.2 Remote ON The Remote ON output controls the ON/OFF power to the FDL-978-TX. This output is connected directly to the Power/Mode switch on the TC-978 and should be connected to the REM ON input (J1-32) of the FDL-978-TX. 2.8.3 TMAP Bus TMAP is a proprietary bus using RS-485 serial communication. TMAP is a bi-directional interface between the TC-978 and the FDL-978-TX. The TMAP differential lines (TMAPA & TMAPB) on the TC-978 must be connected to the corresponding differential lines (TRxD3+ and TRxD3-) on the FDL-978-TX. 2.8.4 Altitude Out The TC-978 outputs pressure altitude data on this RS-232 serial output pin (ALT_OUT) at 9600 baud using the commonly called “Icarus” format. The pressure altitude data that is output depends on the Altitude input configuration. If an Altitude/Air Data functional interface is configured on a FDL-978-TX physical interface, then the pressure altitude data output will be from the configured interface. If no Altitude/Air Data functional interface is configured, then the pressure output defaults to the TC-978 built-in altitude encoder. This output should feed the transponder so they share the same altitude source unless the altitude sensor has multiple outputs to feed both the FDL-978-TX and the transponder. 2.9 PERSONALITY MODULE INSTALLATION The Personality Module is intended to be installed inside the DB-44 connector backshell of the cable harness in the aircraft. The Personality Module allows the FDL-978-TX and the TC-978 to be removed and replaced without having to re-configure the system. The following install kit parts from the FDL-978-TX install kit (p/n 85935-00) are used to install the personality module in the backshell: Item Qty Description

Insert crimped pins into the DB-44 connector housing according to the table above. 4. Adhere one side of the double-sided tape pad to the Personality Module as shown in Figure 8 and the other side should be adhered to one side of the connector backshell as the connector and backshell are assembled together.

FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 II-13 2.10 WIRING CONSIDERATIONS The connection from the FDL-978-TX transmitter to the TC-978 controller uses a minimum of six (6) signal lines; the TMAP pair, the Power and Ground pair, and the Remote On discrete line plus associated ground line. In a certified installation, MIL-W-16878E/4 or equivalent wire should be used. Wire gauge should be 24 AWG for all wires. Shielded, twisted wiring is recommended for the TMAP pair (and all serial data communication pairs) to improved electromagnetic emissions and susceptibility – one twist per 1 to 2 inches is adequate. Other pairs in the bundle can also be twisted but are not required. The distance between the FDL-978-TX transmitter and the TC-978 controller is limited by the impedance of the wire between them. The TC-978 is powered from the FDL-978-TX, not from aircraft power, and therefore the acceptable voltage drop in the power line limits the wire length. The TC-978 needs an impedance of less than 1.0 ohm in the power line for satisfactory operation. The following table gives guidelines for typical aircraft hook-up wire. Note that different brands may vary – check your supplier for details. GAUGE MILIOHM/FT LENGTH FOR 0.5 OHM 24 AWG 30.2 33.2 ft An alternative to a harness built from individual wires, particularly for a long cable run, is to use a multi-core cable. Aviation grade cable with 6 or more cores is often more expensive than the individual wires. Note that not all data cable is suitable for this application. Cables with solid cores should not be used, and cables should be selected based on the wear characteristics of their insulation material, including temperature rating, resistance to solvents and oils, and flammability. Most inexpensive commercial data cables have poor flammability properties. 2.11 UAT ANTENNA INSTALLATION The antenna should be installed according to the manufacturer’s instructions. Selecting appropriate UAT antenna locations is critical to the proper performance of the FDL-978-TX. The following considerations should be taken into account when selecting the Antenna location. • The antennas should be well removed from any projections, the engine(s) and propeller(s). It should also be well removed from landing gear doors, access doors or others openings which will break the ground plane for the antenna. • The antenna should be mounted on the bottom and or top surface of the aircraft and in a vertical position when the aircraft is in level flight. • Avoid mounting the antenna within 3 feet of the ADF sense antenna or any COMM antenna and 6 feet from the transponder and DME antennas. • Where practical, plan the antenna location to keep the cable lengths as short as possible and avoid sharp bends in the cable to minimize the VSWR. Electrical connection to the antenna should be protected to avoid loss of efficiency as a result of the presence of liquids or moisture. All antenna feeders shall be installed in such a way that a minimum of RF energy is radiated inside the aircraft. 2.11.1 UAT Antenna Ground Plane When a conventional aircraft monopole antenna is used it relies on a ground plane for correct operation. For ideal performance the ground plane should be very large compared to the wavelength of the transmission, which is ~12in. In a metal skinned aircraft this is usually easy to accomplish, but is more difficult in a composite or fabric skinned aircraft. In these cases a metallic ground plane should be fabricated and fitted under the antenna.
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 II-14As the ground plane is made smaller, the actual dimensions of the ground plane become more critical, and small multiples of the wavelength should be avoided, as should circles. Rectangles or squares are much less likely to create a critical dimension that resonates with the transmissions. The smallest practical ground plane is a square around 5.25 in per side; as the size increases the performance may actually get worse, but will be better by the time the ground plane is 30.5 in on each side. Anything much larger than that size is unlikely to show significant further improvement. The thickness of the material used to construct the ground plane is not critical, providing it is sufficiently conductive. A variety of proprietary mesh and grid solutions are available. 2.11.2 UAT Antenna Cable The FDL-978-TX is designed to meet Class B1/B1S requirements with an allowance of 2.5 – 6.5 dB for loss in the connectors and cable used to connect it to the antenna. Excessive loss degrades transmitter output power so it is recommended that the installation cable loss be limited to the loss minimum of 2.5dB. Allowing 0.25dB loss for the connector at each end of the antenna cable assembly leaves an allowance of 2.0 – 6.0 dB loss for the cable itself. An acceptable cable then has: • A minimum of 2.0dB loss for the run length but no greater than 6.0dB loss • A characteristic impedance of 50 Ohms • Double braid screens or has a foil and braid screen Once the cable run length is determined, a cable type with the proper attenuation (loss) per foot that meets the above requirements can be chosen. Longer runs require lower loss cable. Consider moving the FDL-978-TX closer to the antenna to minimize the losses in the antenna cable subject to the limits identified above. The following table is a guide to the minimum and maximum usable lengths of some common cable types. Actual cable loss varies between manufacturers and the table is based on typical data. Use the table as a guide only and refer to the manufacturer’s data sheet for the specific cable chosen to calculate the minimum and maximum lengths. CABLE ATTENUATION (dB/100 ft @ 1 GHz)MIN LENGTH (ft) MAX LENGTH (ft) RG-174 27.1 7.4 22.1 RG-316 25.8 7.75 23.25 RG-400 14.5 13.8 41.3 RG-142 12.8 15.6 46.9 RG-393 7.5 26.7 80 When routing the cable, ensure the following: • Route the cable away from sources of heat. • Route the cable away from potential interference sources such as ignition wiring, 400Hz generators, fluorescent lighting, and electric motors. • Allow a minimum separation of 12 inches (300mm) from an ADF antenna cable. • Keep the cable run as short as possible. • Avoid routing the cable around tight bends. • Avoid kinking the cable even temporarily during installation. • Secure the cable so that it cannot interfere with other systems.
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 II-152.12 STATIC PRESSURE CONNECTION The TC-978 controller includes an altitude encoder which must be connected to the same source of static pressure as the primary altimeter on the aircraft. The TC-978 static pressure port provides a mounting spigot intended for nominal 5mm or 3/16 inch inside diameter tubing. A length of 5mm EPDM rubber tubing is included in the installation kit to facilitate connection to the aircraft static system. Choose a point in the existing static pressure line that is as close as practical to the TC-978. Cut the static pressure line, and use the supplied T fitting to connect the altitude encoder. Take care not to contaminate the inside of the static line when cutting or inserting the connectors. The following diagram shows the general arrangement, although other combinations may be used: For aircraft with ¼ inch static lines, two adapters are provided which can convert from ¼ inch inside diameter hoses to the 5 mm hose in the install kit. In all cases, the static line should include drainage provisions and should be routed in accordance with CS 23.1325 or other applicable airworthiness provisions for the aircraft. 2.13 EQUIPMENT LIMITATIONS For a compliant installation in accordance with the Technical Standard Order (TSO) and the Federal Aviation Regulations (FAR), the FDL-978-TX installation must meet the following requirements:  “The conditions and tests required for TSO approval of this article are minimum performance standards. It is the responsibility of those desiring to install this article, either on or within a specific type or class of aircraft, to determine that the article, when installed, performs in accordance with the design specifications that meet this TSO. The article may be installed only if further evaluation by the applicant documents an acceptable installation and is approved by the Administrator.”  The antenna installation must comply with the specifications in Section 2.11.
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 III-1SECTION III CONFIGURATION AND CHECKOUT 3.1 GENERAL This section contains installation configuration, checkout, and basic operating procedures. More detailed operating procedures are contained in the Pilot Guide. 3.1.1 Continued Airworthiness Requirements The FreeFlight FDL-978-TX and TC-978 requires no periodic maintenance or calibration. Maintenance is performed on an on-condition basis only. The FreeFlight FDL-978-TX does a power on self test (POST) and is continually tested periodically using a Built-In Test (PBIT) when the system is in operation. This method of testing will notify the operator of a failure. System software updates are accomplished using the Maintenance Interface. 3.1.2 Normal Controller Operation The FDL-978-TX interfaces to a TC-978 Front Panel Controller used in-flight by the pilot to control output of ADS-B messages. The TC-978 receives its power from the FDL-978-TX and communicates to the FDL-978-TX through a RS-485 serial port. The TC-978 has a monochrome LCD display flanked by a rotary mode selector knob (OFF, SBY, GND, ON, and ALT) and a continuously rotating knob used for code and data entry. 3.1.2.1 Display The display shows the operating mode of the FDL-978-TX, the reported pressure altitude, and the current squawk code and Flight ID. The reply indicator is active when the FDL-978-TX transmits ADS-B messages. The pressure altitude is displayed as a Flight Level, which is the pressure altitude in hundreds of feet. When non-standard atmospheric conditions apply this may not match the altimeter indicated altitude but will be correctly reported in the ADS-B message. 3.1.2.2 Mode Selector Knob The left hand Mode knob controls the power to the FDL-978-TX and the operating mode.
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 III-2 The knob rotates between the different operating modes as defined in the table below: POS DESCRIPTION OFF Power is removed from the FDL-978-TX. SBY The FDL-978-TX is on but will not transmit any ADS-B messages. GND The FDL-978-TX is in normal transmission Mode and reports pressure altitude in ADS-B message if available.

FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 III-183.6.2 Calibrate Altitude Encoder The TC-978 includes a built-in altitude encoder. The front panel reports pressure altitude on pin 4 of the DB-9 male connector on the back of the TC-978 as RS-232 serial data, at 9600 bps, using the format commonly called “Icarus” format. The installation manual provides further details of interfacing the altitude encoder with the primary static pressure of the aircraft altimeter. The calibrate altitude encoder setup allows the recalibration of the altitude encoder. This ensures that the altitude seen on the pilot’s primary altimeter is the same as what is transmitted out of the FDL-978-TX. The maximum allowed difference between the primary altimeter and the altitude encoder is 125 feet in ETSO C88a and TSO C88b. The altitude encoder in the Front Panel Controller is accurately calibrated in the factory to be within 50 feet of the applied pressure altitude at all altitudes, whereas the allowed error in the primary altimeter increases with altitude, and above 18,000 feet the altimeter error alone may exceed 125 feet. It is therefore possible that the combination of the allowed errors in the encoder and the primary altimeter may exceed 125 feet, in which case the altitude encoder must be adjusted to correspond to the primary altimeter. Note: The purpose of calibrating the encoder is to make the output correspond to the primary altimeter. The encoder calibration procedure must therefore only be undertaken after the primary altimeter has been tested and found to comply with the relevant standards. 3.6.2.1 Calibration Equipment To calibrate the encoder the TC-978 must be powered up and you will need a pitot-static test set with the appropriate adapters to connect to the static port on the aircraft. The pitot-static test set should be able to drive the altitude down to sea level, and above the service ceiling of the aircraft. No test set is required – the calibration procedure displays all the information you need on the screen of the Front Panel Controller 3.6.2.2 Calibration Procedure There are two adjustment points on the altitude encoder, a low altitude adjustment point, and a high altitude adjustment point. The low altitude point adjusts the correspondence at sea level, and the high altitude point adjusts the correspondence at the altitude limit of the encoder. Since the altitude limit of the encoder is likely to be higher than the service ceiling of the aircraft, it is sufficient to set the upper adjustment at the service ceiling of the aircraft. Note: DO NOT EXCEED THE ALTITUDE OR RATE OF CLIMB LIMITS OF THE PITOT-STATIC INSTRUMENTS OF THE AIRCRAFT. The TC-978 altitude encoder is a solid state device and will not be affected by excess altitude or rate of climb and descent, but the mechanical instruments in the aircraft can easily be damaged by being driven beyond their intended range.
FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 III-191. Set the primary altimeter subscale setting to 1013.2 hPa, 29.92 in hg. 2.

Read the primary altimeter value; rotate the code knob either clockwise or anticlockwise until the altitude displayed on the front panel matches the aircraft primary altimeter. Press and the display will move to the test altitude screen which is the next configuration item in the setup mode. 11. To complete the testing you should leave the front controller screen displaying the encoder altitude, and exercise the altitude on the static test set across the altitude range of the aircraft. The display will be as shown above for pressure reported. Use at least 10 test points, and verify that in each case the altitude displayed on the primary altimeter and the altitude displayed on the front panel correspond within the 125 foot tolerance. Lightly tap the altimeter at each test point to eliminate friction effects. When the correspondence test is complete, press again on the front panel, and power off the system. 3.6.3 Pressure Altitude Reported Pressure altitude is displayed after the altitude calibration setup has been completed.

FDL-978-TX ADS-B Transmitter Installation Manual 86960, Revision A September 1, 2011 VI-1SECTION VI SERIAL INTERFACE SPECIFICATIONS Two data formats may be selected to accept input from external Altitude sensors: • Encoder Altitude – gray-code to serial altitude converters, etc. • Air Data Computer – To select a data format, refer to section B.4. The baud rate of each of these formats is automatically set; ENCODER is 9600 baud and RMI is 1200 baud. 6.1 ALTITUDE ENCODER FORMAT The Altitude Encoder data format accepts messages with the following parameters: Baud: 9600 Parity: None Start Bit: 1 Data Bits: 8 Stop Bit: 1 Update Rate: 1 msg/sec Compatible devices include Rosetta Encoders and Serializers (ARS 50 and ARS 100). The compatible format for altitude information is the following 10 byte ASCII message: BYTE 0 1 2 3 4 5 6 7 8 9 CONTENTS A L T 1 2 3 4 5 c/r Some examples include: 'ALT 00000' 0 feet 'ALT -1200' -1200 feet 'ALT 62505' 62,505 feet 'ALT 05604' 5,604 feet 6.2 AIR DATA COMPUTER FORMAT The Air Data computer format accepts messages withthe following parameters: Baud: 9600 Parity: None Start Bit: 1 Data Bits: 8 Stop Bit: 1 Update Rate: 1 msg/sec Air Data messages are accepted when the serial port is set to "ENCODER". A packet consists of a set of ASCII message strings. The first character of each packet is an ASCII Start-of-Text (STX = 02H). The last character of each packet will be an ASCII End-of-Text (ETX = 03H). Each message string begins with one ASCII character to identify it as an Air Data message ("Z"). The second character identifies which message it is. The rest of the string consists of one or more alphanumeric ASCII fields. Each message field ends with a carriage return, line feed (CR = 0D0AH). All numeric fields are ASCII decimal, right justified and zero filled. If the Air Data Computer cannot supply data in a particular field, the field is filled with dashes ("-" = 2DH). The table below lists the message items used by the FDL-978-TX. Additional items may be in the message but they are not used by the FDL-978-TX.
