DESCRIPTION OF EQUIPMENT

The Trimble 2000 Approach Receiver provides long-range GPS navigation via a panel-mounted unit. Each system comprises receivers and antennas to perform specified functions. The Jeppesen database cards provide up-to-date information about airports and other navigation aids around the world. The Trimble 2000 Approach GPS System contains one panel-mounted Receiver/Display Unit (RDU) containing a GPS Receiver (9-channel), one GPS Antenna/Preamp, and applicable installation hardware all contained within P/N 81446-XX (see Table 1-1 for appropriate dash number). The Jeppesen database cards are available separately within P/N 81461-00 for North American information, P/N 81461-01 for International information, or P/N 81461-02 for Worldwide information. The first card is supplied by Trimble.

1.2.1

Receiver/Display Unit

The Receiver/Display Unit (RDU) is the main component of the Trimble 2000 Approach navigation systems. The RDU consists of the GPS Receiver, the User Interface, and the System Interface. 1.2.1.1 GPS Receiver The GPS Receiver interprets the satellite transmissions to determine the current position. This information is communicated to the pilot via the User Interface and to the connected equipment via the System Interface. 1.2.1.2 User Interface The User Interface is accomplished by an LED Display, seven annunciator lights, nine illuminated push-button keys, two concentric selector knobs, a power switch, and a NavData card slot. A.

LED Display The Light Emitting Diode (LED) Display is a two-line, high intensity display with 20 characters per line. System information is shown on the display.

B.

Annunciator Lights The internal annunciator lights alert the pilot of warning and advisory messages. The annunciator lights are the Message (MSG), Hold (HLD), Parallel Track (PTK), Approach (APR), Waypoint Alert (WPT), Global Positioning System (GPS) and Random Autonomous Integrity Monitoring (RAIM).

C.

Push-Button Keys Nine illuminated push-button keys are used for mode selection and data entry. The keys are described as follows: Access Navigation Mode. Displays enroute navigation information.

Access Waypoint Mode. Allows pilot to view or select airports, SIDs, STARs, Approaches, VORs, NDBs, Intersections, and User-defined locations as waypoints in a flight plan or as a destination. Also allows pilot to create, edit, or delete User-defined waypoints. Access Flight Plan Mode. Allows pilot to create, use, edit, reverse, and delete flight plans.

Access Calculator Mode. calculations.

Access Auxiliary Mode. Provides information about system status, sensor status, system setup and installation procedures. Also contains a programmable checklist function. Shows twenty nearest airports, VORs, NDBs, and Intersections.

Allows pilot to fly directTo the indicated location or activate the indicated flight plan.

Enters information into memory and used to begin and end data entry.

Allows the pilot to view system messages.

D.

Selector Knobs Two concentric selector knobs are used to select displays within modes and for data entry.

E.

Power Switch A push-pull power switch turns the RDU on and off.

F.

NavData Card Slot The NavData card slot accepts the Jeppesen NavData card which provides the pilot information on Airports, SIDs, STARs, Approaches, VORs, NDBs, and Intersections. Either a North American or International database may be used. The slot also accepts the Trimble NavPak Memory Card used by the Trimble NavPak flight planning system.

1.2.1.3 System Interface The Trimble 2000 Approach communicates with connected equipment by the CDI outputs, Annunciators, and the Serial Inputs/Outputs. A.

CDI Outputs The RDU provides standard Course Deviation Indicator (CDI) output signals suitable for use by most CDIs.

B.

Annunciator Outputs The external annunciator lights alert the pilot of warning and advisory messages. The annunciator lights are Message (MSG), Hold (HLD), Waypoint Alert (WPT) and Approach (APR).

C.

Serial Inputs/Outputs The RDU provides two serial input ports and two serial output ports for general use. Data formats may be selected by the pilot.

1.2.2

GPS Antenna

The GPS Antenna (P/N 16248-20) receives and amplifies GPS Signals. The GPS Antenna unit is an omnidirectional flat microstrip antenna with an integral preamplifier and is rated to 600 knots IAS. Two alternate antennas (P/Ns 1624811 & 81194) can be used with the Trimble 2000 Approach.

Electrical Inspection

Each new Trimble 2000 Approach is tested and adjusted during final inspection at Trimble before shipment. Normally, unless damage is evident, it is not necessary to do a pre-installation electrical inspection.

2.3

EQUIPMENT INSTALLATION 2.3.1

Cooling Considerations

The greatest single contributor to increased reliability of avionics is to limit the maximum operating temperature of the individual units, whether panel or remote mounted. While circuit designs today consume far less electrical energy, the watts per cubic inch dissipated within avionics units still remains much the same due to high density packaging techniques. Consequently, the importance of providing avionics cooling is essential to the life span of the unit. While each individual unit may or may not require forced air cooling, the combined heat load of several units operating in a typical avionics location will significantly degrade the reliability of avionics if provisions for cooling are not incorporated in the initial installation. Failure to provide cooling will certainly lead to increased avionics maintenance costs and may void the Trimble Navigation Warranty.

2.3.2

Harness and Cable Fabrication

The installation agency must supply and fabricate all external cables. The length and routing of external cables must be carefully studied and planned before proceeding with the installation of the equipment. Avoid sharp bends or routing the cable too close to aircraft control cables and power sources. When necessary to cross power cables, use shielded cable and cross at right angles. Take special precaution when transitioning pressure envelopes. Use cable to connector sealant. Figure 2-1 is the pin-out diagram and Figure 2-7 is a typical system interconnection.

2.3.3

GPS Antenna Installation

The GPS antenna installation kit is included in all of the shipping kits. The GPS Antenna installation kit contains the GPS Antenna, the GPS antenna cable, and the required connectors. Proper antenna installation is critical to both the performance of the system and the aircraft's structural integrity. 2.3.3.1 Location In order to receive transmissions from GPS satellites, the GPS antenna must be in line-of-sight with the satellite. Therefore, the most important factor in GPS antenna installation is determining which location on the fuselage affords the least amount of airframe blockage. Always mount the antenna on the top of the fuselage, never on the underside. Also, mount the antenna so that the mounting holes are perpendicular to the line of flight. Select a mounting location at least three (3) feet away from any transmitting antenna. On fixed wing aircraft, the best mounting location is usually above the cabin, near the front, and as close to the center line as possible. 2.3.3.2 Location Considerations on Rotorcraft As in fixed wing aircraft, the primary factor in rotorcraft GPS antenna site selection is to minimize airframe blockage. Two other guidelines to be considered in placing the antenna on rotorcraft are listed in order of importance below: A.

Install as far from the main rotor hub as possible. At a given RPM, the linear velocity of the blade increases as the distance from the rotor hub increases. Since the blade blocks the line-of-sight GPS satellite signal, the effect will be reduced further away from the rotor hub.

B.

If under the blade, get as far below the blade as possible to minimize signal distortions from the blade edges, which decrease as the distance from the blade increases.

2.3.3.3 Wiring A GPS cable assembly (P/N 14719-00) is supplied as part of the system. The supplied cable is 20 feet long. An alternate 50 foot long prefabricated cable is available from Trimble (P/N 14719-01). For installations longer than 50 feet, the installation agency is responsible for the fabrication of the cable (see Section 1.5.2). The included cable assembly is tested prior to shipment and should be used to ensure proper performance. Take care when routing cable to avoid kinking and sharp bends. If antenna cable is routed through bulkheads, be sure to install protective material to avoid chafing. 2.3.3.4 Installation

CAUTION Before drilling aircraft fuselage and/or mounting adapter holes to receive the GPS Antenna, make certain the hole pattern for the antenna is oriented with respect to its forward direction. After a suitable mounting location is identified, position and affix the adhesive-backed mounting template supplied with the antenna, refer to Figures 2-2, 2-3 & 2-4. Drill the holes and install the supplied (or equivalent) antenna doubler. Be sure to remove the mounting template prior to installing the antenna.

Fastening to Fuselage (for 16248-20 & -11 antennas)

CAUTION Do not tighten screws with more than 20 inch-pounds of torque. Damage to antenna will result and void warranty. Torque value = 18 ±2 inch-pounds. Install screws through antenna, gasket, and aircraft skin into captive nut plates. Tighten the screws to 18 ±2 inch-pounds of torque. Use non-corrosive RTV or similar sealant to seal around antenna base and screw holes. •

Fastening to Fuselage (for 81194 antenna)

CAUTION Do not tighten screws with more than 28 inch-pounds of torque. Damage to antenna will result and void warranty. Install screws through antenna and aircraft skin into captive nut plates. Tighten the screws to 26 ±2 inch-pounds of torque.

2.3.4

Receiver/Display Unit Installation

2.3.4.1 Location Select a mounting location that will allow easy viewing of the unit's display during normal instrument panel scan and allow easy access to the front panel controls. After the desired mounting location is identified, refer to Figures 2-5 and 2-6 for unit outline and mounting dimensions for the unit and the mounting tray. Relocate existing equipment as necessary. 2.3.4.2 Mounting Tray Installation Fabricate harness and assemble the tray. Directions for assembly are shown on Figure 2-6. 2.3.4.3 Placard Use Placard use is dictated by the particular installation. The installation agency is required to fabricate a placard to label the annunciators, transfer switches, and circuit breakers. 2.3.4.4 Wiring The external wire supplied by the installing agency should be 22 gauge with the exception of the serial communication connections (pins 3, 4, 5, 15, 16, and 17). Serial communication connections require 22 or 24 gauge twisted shielded pairs. Refer to pin-out diagram Figure 2-1. For CDI/HSI interconnections, refer to Figure 2-8. For Serial Port Interconnections, refer to Figure 2-9. These considerations should be followed to ensure proper interface. A.

Audio output (pin 20) impedance is 600 Ω. The CDI common (pins 18 and 22) may be used for Audio Common.

B.

The Message annunciator (MSG), pin 23, Hold annunciator (HLD), pin 12, Waypoint Alert annunciator (WPT), pin 24, and Approach annunciator (APR), pin 11 duplicate the annunciators on the front panel. These pins are connected to open-collector transistors which may sink a maximum of 200 mA. Should they be connected to a relay for higher current capability, the relay must have a protection diode placed across the coil. The pins will be sinking current when the annunciator condition is true.

C.

Jumper the Safeguard Enable (pin 21) to the CDI Common (pin 22) at the rack connector to ensure operation of the theft protection circuit.

D.

Serial Port 1 (pins 3, 4, 15, and 16) is designed for signals adhering to the RS-422 standard. If singleended RS-232 signals are used, an adapter (Trimble P/N 12480-00) should be used to maximize noise immunity. The signals will work with most RS-232 devices without an adapter, but at some loss of noise immunity.


Page 2-3




2.3.5

E.

Serial Port 2 (pins 5 and 17) is a single-ended TTL output which meets the logic polarity requirements of RS-232. The port 2 output does not meet all of the requirements of the RS-232 standard, so in some installations an adapter (Trimble P/N 12480-00) may be required. If RS-422 differential signals are required, an adapter (Trimble P/N 12480-00) must be used.

F.

Only a single device may be connected to each serial input port (RXD1 and RXD2). Up to 5 devices may be connected in parallel to each serial output port (TXD1 and TXD2), provided that all devices in parallel use the same message format and data rate (e.g., K0 at 9600 baud).

G.

Pin 19 will be supplied from the factory as a 14 Vdc or 28 Vdc Superflag driver. A jumper may be moved inside the unit to change pin 19 to provide One Pulse-Per Second (PPS) output. The One PPS output is a TTL pulse, 1 ms wide, occurring once per second (referenced to CDI common pin 18 or 22). When GPS time is available, the leading edge of One PPS is synchronized to GPS time within 1 ms. CAUTION: Do not connect pin 19 directly to GND.

Outside Air Temperature Probe (OAT) "K" Factor

If an Outside Air Temperature Probe is installed, a Temperature Recovery Coefficient, known as the "K" factor, should be set to correct True Airspeed for temperature rise at the probe. The OAT "K" factor is set to 1.0 at the factory. Contact the OAT probe manufacturer for infomation on selecting this value. Refer to the Pilot Guide for instructions on how to set the OAT "K" factor.

GENERAL

This section contains installation checkout, system configuration, and basic operating procedures. More detailed operating procedures are contained in the Pilot Guide.

3.2

SYSTEM CHECKOUT 3.2.1

Preliminary test

Before the unit is installed and tested, verify the accuracy of the installation. With the unit removed, turn on the power and verify the following: 1.

Verify that Aircraft dc bus voltage is present on pins 1 and 2. Also, if external annunciators are installed, verify that voltage is present on pins 11, 12, 23, and 24.

2.

Verify that ground is present on pins 13 and 14.

3.

Verify the continuity between pins 21 and 22.

4.

Make sure the mounting tray is securely fastened and properly braced.

5.

Verify that the GPS antenna connector is not shorted and demonstrates some play.

When the above conditions are verified, turn off the master power. Slide the unit into the mounting tray and tighten the locking device. Turn on the unit. During initialization, the unit performs a comprehensive diagnostics routine. A failure of any system component is annunciated by a flashing "Fail" message adjacent to the relevant category. This failure will cause the Message (MSG) annunciator to light and remain lit. Consult the Pilot Guide for more information concerning FAIL messages.

GPS Receiver Tests

Prior to performing the GPS receiver test, make s ure the aircraft is outside and away from any tall buildings or objects which will obstruct the line-of-sight communication between the unit's antenna and the satellites. 3.2.3.1 Satellite Signal Reception To conduct the GPS receiver tests on units, press the selected. The display below is shown.

Rotate the large, outer selector knob until a display similar to the one below is shown.

        

This display indicates the number of satellites being tracked (6) as well as identifying each satellite tracked (by number). A flashing satellite number indicates a satellite which is being tracked but not being used in the position solution. The GPS annunciator on the Trimble 2000 Approach front panel indicates that sufficient satellites are being used to provide position updates. 3.2.3.2 Comm Test Harmonic interference from VHF transmissions on the following frequencies may affect GPS signal reception: Frequency in MHz 121.150 121.175 121.200 131.250 131.275 131.300 Installations intended for IFR approvals should be tested to ensure no interference is generated by VHF transmissions. For each interfering frequency, perform the following test: 1.

Tune the VHF radio to the frequency under test.

2.

While observing the GPS satellites tracked display and internal GPS annunciator, key the VHF transmitter for 20 seconds.

3.

If the number of satellites in use drops to the point that GPS navigation is no longer possible (GPS annunciator illuminates), then too much interference exists between VHF radio and the Trimble 2000 Approach. Two common sources of interference are from the VHF radio front panel to the GPS antenna and from the VHF antenna to the GPS antenna. To minimize front panel to antenna interference, ensure that all cabin doors and windows are closed when performing the test. This type of interference is also minimized by being away from the ground and ground structures. If required, the test may be performed in flight. Finally, the location of the GPS antenna may affect levels of VHF front panel to GPS antenna interference.

APPENDIX B - Serial Interface Specification B.1

INTRODUCTION

Serial communication capabilities for the Trimble 2000 Approach are provided by two bi-directional serial communication ports compatible with EIA RS-232 and RS-422 protocols. Different formats may be selected on each port providing the user flexibility in interfacing various systems with the Trimble 2000 Approach. All information contained in this section is subject to change without notice.

B.2

BASIC COMMUNICATION PROTOCOL DESCRIPTIONS B.2.1

RS-422

The RS-422 protocol uses differential signals with a m agnitude in the range of 2-6 volts and a polarity as follows: Logic 1: The non-inverting (+) signal is negative with respect to the inverting (-) signal (Signal Condition = MARK). Logic 0: The non-inverting (+) signal is positive with respect to the inverting (-) signal (Signal Condition = SPACE). RS-422 has the capability of driving up to ten receive devices in parallel from a single transmitter. It can drive long cable lengths and has superior noise immunity.

B.2.2

RS-232

The RS-232 protocol specifies a bipolar, unbalanced signal referenced to a common ground (serial common). For example, for RS-232D, the polarity is as follows: Logic 1: The transmitter voltage is between -5V and -15V (Signal Condition = MARK). Logic 0: The transmitter voltage is between +5V and +15V (Signal Condition = SPACE).

B.2.3

RS-423

The RS-423 protocol specifies a bipolar, unbalanced signal referenced only to the transmitter's ground and is received differentially. The polarity is as follows: Logic 1: The transmitter voltage is -4V to -6V (Signal Condition = MARK). Logic 0: The transmitter voltage is +4V to +6V (Signal Condition = SPACE).

Transmit Ports 1 and 2 (TXD1 and TXD2) provide interface capability with a variety of peripheral devices such as moving maps and fuel flow computers, computers, as well as providing data to users for custom applications. Adapters are available for each port to provide RS-422 and/or RS-232 signals. signals. No hand-shaking lines are provided. Six data formats are available for use and may be s elected in the INSTALL submode of the AUX mode (See Section B.4). These formats are RNAV 0 and 1 (R0 and R1), King 0 and 1 (K0 and K1), and Extended King 0 and 1 (X0 and X1). Formats R0 and R1 may be set to any baud rate (from 1200 baud to 38.4 kbaud, excepting 19.2 kbaud) while formats K0, K1, X0, and X1 may only be set to 9600 baud or 38.4 kbaud. The update rate may be set from 1 to 999 seconds for any of the formats. The only exception is if the baud rate is 1200. For this case, the maximum update rate is 2 seconds. The data stream is a string of ten-bit serial ASCII characters consisting of one start bit, eight data bits, and one stop bit. No parity is generated. Data messages begin with an ASCII Start of Text (STX) character and end with an End of Text (ETX) character. A single alphabetic character precedes each data element.
