GENERAL INFORMATION V1 INTRODUCTION This manual contains information relative to the physical, mechanical, and electrical Characteristics of the Bendix/King Crown Series KLX 135/135 VHF Communication Transceiver/GPS Receiver. Installation and operating procedures are also included. Information relative to the maintenance, alignment, and procurement of the replacement parts may be found in the KLX 135/135A Maintenance/Overhaul Manual, P/N 006-15500-XXXX. 1.2 EQUIPMENT DESCRIPTION The KLX 135/135A, is a 13.75 volt panel mounted, Communication Transceiver/GPS Receiver designed to provide the following functions: ‘A. TSO'd two-way VHF voice communication within the frequency range of 118.000 MHz to 196.975 MHz (760 channels) in 25 kHz selectivity. Two communication frequencies (active and standby) can be entered via concentric knobs and button on the left hand. side of the front panel and displayed in the upper left corner of the display. The active and standby frequencies may be exchanged from either the front panel or using a emote transfer, A way to transfer the communication frequencies from the database @ (QuickTune TM) is also provided. It has a 5 watt transmitter with a feature to prevent transmitter operation if the microphone is stuck. Audio amplification of the receiver output, as well as outputs from auxiliary devices is provided via the built-in audio ampliier B. A Non-TSO'd GPS based, long range airborne navigation system with a data base. The primary purpose of the GPS navigation portion of the KLX 135/135A is to provide the pilot with present position information and to display guidance information with Tespectto a flight plan defined by the pilot. Flight plan information is entered by the pilot via the concentric knobs and button on the right hand side of the front panel. The unit can use its present position information to determine crosstrack error, distance-to-waypoint, ground speed, track angle, time- to-waypoint and bearing to waypoint. Some of this data is output to external devices. The internal data base of the KLX 135/138A contains information concerning airports, VORs and NDBs. (The KLX 195A also displays information about SUA's airport runways and frequency location inforrnation, nearest FSS and ARTCC names and frequencies). Waypoints are stored in the data base by their ICAO identifiers. The ICAO identifiers are in most cases taken directly from Jeppessen Sanderson or government aeronautical charts. The information stored in the data base eventually becomes out of date. Therefore, to provide a means of updating the information, the data base is designed to be updatable ® by use of a personal computer, usually a laptop, via 3 1/2" 1.44M diskettes. IMKLX435/AJKD Rev 3 Aug/95 Page 1-1BENDIX/KING KLX 1356/1350 COMMUNICATION TRANSCEIVER/ GPS RECEIVER C. An alphanumeric liquid crystal display (LCD) is used to display frequencies and navigation information including a course deviation display. Connections to the unit are made through one 44 pin and one 30 pin Molex printed circuit board edge connector and two BNC coaxial connectors at the rear of the unit. D. The KLX 135 is available under P/N 069-01029-0201. The KLX 135A, P/N 068-01028-0703, is identical to the KLX 135 except that it has an improved alphanumeric liquid crystal display (LCD), uses a different type of data base, and has a moving map display, 1.3.

To ensure that the system has been properly and safely installed in the aircraft, the installer should make a thorough visual inspection and conduct an overall operational check of the system on the ground prior to light. CAUTION AFTER INSTALLATION OF THE CABLING AND BEFORE INSTALLATION OF THE EQUIPMENT, A CHECK SHOULD BE MADE WITH THE AIRCRAFT PRIMARY POWER SUPPLIED TO THE MOUNTING CONNECTOR TO ENSURE THAT POWER IS APPLIED ONLY TO THE PINS SPECIFIED IN THE INTERWIRING DIAGRAM, FIGURE 2-1. IMKLX135/AJKD Rev 8 Augi95BENDIX/KING KLX 135/136 COMMUNICATION TRANSCEIVER/ GPS RECEIVER The KLX 135/135A system installation will conform to standards designated by the customer, installing agency and existing conditions as to the unit Iocation and type of installation, However, the following suggestions should be considered before installing your KLX 135/136A system. 232 AVIONICS COOLING REQUIREMENTS FOR PANEL MOUNTED EQUIPMENT. ‘The greatest single contributor to increased reliability of all modem day avionics is to limit the maximum operating temperature of the individual units whether panel or remote mounted. While modem day individual circuit designs consume much less electrical energy, the watts per cubic inch dissipated within avionics units remains much the same because of high density packaging techniques utiized. Consequently, the importance of providing avionics stack cooling is essential to the life span of the equipment. While each individual unit may not require forced air cooling, the combined heat load of several Units operating in a typical avionics stack will significantly degrade the reliabllty of the avionics if Provisions for stack cooling are not incorporated in the initial installation. Recommendations on stack cooling are contained in BendivKing Installation Bulletin #55. Failure to provide stack cooling will certainly lead to increased avionics maintenance costs and may void the warranty, 2.3.3 KLX 195/135A INTERWIRING AND CABLE HARNESS FABRICATION A. General ‘The KLX 135/135A Communication Transceiver/GPS Receiver receives primary Power from the aircraft power source, Power connections, voltage requirements and Circuit breaker requirements are shown on the interconnect diagram (Figure 2-1), ‘The length of the wires to parallel pins should be approximately the same length, so that the best distribution of current can be effected. AlliedSignal General Aviation Avionics recommends that all wires, including spares as shown on the interconnect diagram be included in the fabrication of the wiring hamess. However, if full wiring is not desired, the installer should ensure that the minimum wiring requirements for the features and functions to be used be incorporated, When cables are installed in the aircraft, they must be supported firmly enough to Prevent movement and should be carefully protected against chatting, Additional Protection should also be provided in any location where the cable may be subjected to abuse. |n wire bundles, the cabling should not be tied tightly together as this tends to increase the possibilty of noise pickup and similar interference. When routing cables through the aircraft the cables should cross high level rf lines at right angles. The following guidelines are recommended: (1) The installing facility will supply and fabricate all extemal cables. (See Figures 2-1 through 2-5). The required connectors are supplied as part of the installation kit (P/N 050-02217-00Xx), IMKLX135/AJKD Rev 3 Augi95,BENDIX/KING KLX 135/135A COMMUNICATION TRANSCEIVER/ GPS RECEIVER (2) The KLX 135/154 and the associated wiring hamess must be kept a minimum of three feet from the transceiver antenna coax and the termination connector of the antenna to prevent rf interference from the antenna. (3) Do not route the transceiver antenna coax near ADF sense or loop antenna cables, Primary Power and Circuit Breaker Requirements and Wiring The KLX 135/135A transceiver/receiver receives primary power from an aircraft by aircraft power circuit breakers. The KLX 135/135A is designed to operate receiving with a +14 V de supply. Power connections, and circuit breaker requirements are shown on the interconnection diagram Figure 2-1. Audio Installation Description The audio system within the KLX 135/135A provides maximum flexibility for use in a variety of audiofintercom configurations. The KLX 195/135A provides audio amplification for its VHF communication transceiver for both headphones and the cockpit speaker. In addition up to three external sources of audio may be amplified and sent to the headphones and speaker. With proper extemal switching, the KLX 195/135A can provide the microphone bias voltage and ampification necessary for the implementation of a push to talk or a hot mic intercom. The KLX 135/135A provides access to signals not commonly found on communication transceivers to allow full featured installation with audio switching panels and audio isolatior/amplifier panels. Three auxiliary audio inputs AUX #1 AUDIO IN (P4001-M), AUX #2 AUDIO IN (P4001-12) and AUX #3 AUDIO IN (P4001-11) are typically used to amplify audio from VORILOC, Marker Beacon, ADF, DME, Radio Altimeter Decision Height Alerters and other avionics audio sources. Any signal capable of driving a 500 ohm, or lower, load that is adjustable to less than 7 volts is acceptable. All three inputs share a common low, that is connected to ground inside the KLX 135/135, Should you have more than three audio sources it is sometimes possible to successfully connect more than one source to a single pin. The sources will in addition to driving the KLX 135/135A input load be driving the other source outputs as loads. Normally this does not damage the source units but can cause lower signal levels resulting in less audio from these sources sharing the input pin. in addition turning off one of the sources may stop audio from all the sources sharing that input pin, COMM AUDIOISIDETONE IN (P4001-E) and INTERCOM MIC IN (P4001-D) are inputs to the same amplifier used for the auxiliary audio inputs. The COMM AUDIO/SIDETONE IN is reserved for the COMM AUDIO/SIDETONE OUT and has 2.3, times the gain of the aux audio inputs. The INTERCOM MIC IN provides a MIC bias voltage output and should only be connected to aircraft microphones. Connection to other devices may result in damage to both the KLX 135/195A and the other device, IMKLX135/AJKD_ Page 2-3 Rev 3 Aug/95BENDIX/KING KLX 135/135A COMMUNICATION TRANSCEIVER/ GPS RECEIVER Connecting two microphones to the COMM MIC IN or INTERCOM MIC IN at the same time may result in weak or distorted audio. Variations in microphones, even with identical manufacturers part numbers, can produce this problem when both are connected at the same time. Microphone isolation relays are recommended so that only one microphone is connected at one time. Hf intercom audio is placed on the speaker, it may cause undesirable audio feedback, To prevent this condition, it is common to interrupt the connection between AUDIO ‘SUM OUT and 4 OHM AUDIO IN HI when the intercom is keyed. When the intercom is keyed this relay also prevents audio from any source from being heard on the speaker. Al audio sources remain on the headphones when the intercom is keyed. All five inputs described above are combined and amplified and output on the 500 OHM AUDIO OUT HI (P4001-13) and AUDIO SUM OUT Hi (P4001-R). Both pins have identical signals but are at different voltage levels. The 500 OHM AUDIO OUT will drive headphones directly. The AUDIO SUM OUT is provided so that it may be input to the KLX 135/135A's internal 4 ohm speaker amplifier. No signals, other than the five inputs, are output from the amplifier. No other signals are automatically added to the output, thus allowing the installer complete flexibility. 4 OHM AUDIO IN Hi (P4001-5) is the input to the speaker amplifier. Only the signal applied to this input will be output on 4 OHM AUDIO OUT HI (P4001-P) output. The output will drive speakers of greater than 4 ohm impedance, but since higher impedance speakers may expect higher voltages they may not be as loud as 4 ohm speakers. The speaker amplifier is muted (output is disabled) when the COMM. transmitter is active (MIC KEY input is low), When a separate audio panel is used, neither the 500 ohm or 4 ohm audio amplifiers in the KLX 135/135A are connected. The KLX 135/135 audio amplifiers do not need external loads applied to either their inputs or outputs when they are not used. 2.3.4 EQUIPMENT LOCATION Care should be exercised to avoid mounting components near equipment operating with high pulse current or high power outputs such as radar and satellite communications equipment. In general, the equipment should be installed in a location convenient for operation, inspection, and Maintenance, and in an area free from excessive vibration, heat, and noise generating sources. All mechanical installation drawings, connector assembly diagrams, interwiring diagrams, and connector pin assignment tables referenced in this section are located at the end of this section of the manual. Determine the mounting location for system components following the guidelines below, Prior to installing any equipment, make a continuity check of all wires and cables associated with the system. Then apply power and check for proper voltages at system connectors, and then Temove power before completing the installation, IMKLX135/AJKD Reva Augi95SS EET a Ty UIT TT TTT eT te TS Tae ee ae ee BENDIX/KING KLX 135/1354, COMMUNICATION TRANSCEIVER’ GPS RECEIVER A. _KLX 185/135A Communication Transceiver/@PS Receiver Locations NOTE + Care must be taken in selecting the optimum location for the KLX 135/135A. + The LCD, Liquid Crystal Display, has viewing angle limitations. (See Figures 2-6 and 2-7) The installation of the KLX 196/135A must not exceed these viewing angles. The viewing angle should be checked with both the plots and the copilot's ‘seats in the full forward position. 5 + Insome potential mounting locations, glare and reflection trom the display may cause the display fo be nearly unreadable, Therefore, careful considerations of these effects should be made before choosing the final mounting location. Refer to Figures 2-6 and 2-7. ‘The panel-mounted KLX 135/135A can be installed in any convenient location on the Panel that is free from excessive heat and vibration and which provides reasonable access for inspection and maintenance. Toallow for inspection or repair of the wiring of the connector assembly itself, sufficient lead length should be left so that when the mounting hardware for the rear connectors and antenna coaxial cable is removed the assembly may be pulled forward several inches. Also, a bend should be made in the harness (at the rear connectors) to allow water droplets that might form on the hamess due to condensation, to drip off at the bend and not collect in the connection. ‘The length of cables from the KLX 135/135A connector to other system units is not critical because unit interfaces are designed with high impedance inputs, low impedance outputs, and low noise susceptibility characteristics, Forced air cooling is recommended but is not a rewjuirement. Outline drawing Figure 2:5 shows KLX 135/135 Communication Transceiver/GPS Receiver dimensions. 8, COMM Antenna The antenna should be well removed from any projections, the engine(s), and propelier(s). It should also be well removed from landing gear doors, access doors, or other openings which will break the ground plane for the antenna. The ground plane surface directly beneath the COMM antenna should be a flat plane over as large an area (18 inches square, minimum) as possible, IMKLX135/AJKD Rev 3 Aug/95 Page 2-5Page 2-6 BENDIX/KING KLX 135/135A COMMUNICATION TRANSCEIVER/ GPS RECEIVER ‘A Conventional 50 Q vertically polarized COMM antenna is required with the KLX 135/135. Vertically bent whip communication antennas are not recommended. Wideband COMM antennas provide efficient operation over the COMM band, ‘Antennas should be installed according to the manufacturer's recommendations. ‘back-up plate should be used for added strength on thin-skinned aircraft. To prevent rf interference, the antenna must be physically mounted a minimum distance of three feet from the KLX 135/135A and the wiring hamess. The antenna should be mounted a minimum of six feet away from the OME antenna and four feet from the ADF sense antenna. Where practical, plan the antenna location to keep cable lengths as shor as possible and avoid sharp bends in the cable to minimize the VSWR. Avoid running other cables or wires near the antenna cable. On pressurized aircraft, the antenna should be sealed using ATV No. 3145 {PN 018-01082-0000) or equivalent around the connector and mounting hardware, All antenna mounts should be sealed around the base from the outside for moisture protection using RTV or equivalent. Mount the antenna in as clean an environment as possible, away from exhaust gases and oils. The antenna should be kept clean. If eft dirty (oil covered), the range of the transceiver/receiver may be affected. ‘The antenna connectors on the KLX 136/135A are identified on the rear die casting, GPS Antenna 1) The KA 91 and KA 92 GPS active antennas, P/N 071-01545-0200 and 071-01653-0200 respectively, are the designated antennas for the KLX 135/135. 2) The antenna should be mounted on top of the fuselage near the cockpit. Avoid Mounting the antenna near any projections, the propeller, and the T-tail of the aircraft, where shadows could occur. It is recommended that there be a Separation of at least 3 ft between the GPS antenna and any VHF Comm antenna ‘On the aircraft. Antenna baseplate must be level within + 5° in both axes when the aircrafts in level light. If the antenna is tilted more than 4:5° or is mounted close to other objects that shadow it, loss of some of the satellites will occur and system performance may be degraded. Antenna cable and connector information, including vendor information, is listed below. Refer to figure 2-14 (TNC) and figure 2-15 (BMA) for cable/connector assembly instructions for the 0 to 40 feet category using RG 400/U or RG 1428/U, Reter to figure 2-16 (for both TNC and BMA) for the 0 to 80 feet and 0 to 100 feet categories.

(2) Tinthe exposed conductor. (8) Using needle nosed pliers, fold over each conductor tab, in tum, onto the exposed conductor. when both tabs have been folded, firmly press the tabs against the conductor, Solderless Contact Terminal Assembly using Molex Crimper (Figure 2-3) (1) Strip each wire 5/82" for contact terminal (KPN 030-01107-00XX). (The last two digits of the contact terminal part number indicates the number of terminals required). Open the Molex hand crimper HTR-6115 with the engraved side toward the operator. Place the conductor tab section of a contact terminal on Anvil B with the contact portion facing away from the operator. Close the crimper slightly until the contact tabs touch the female jaw. (3) _ Insert the stripped conductor until the insulation is even with the side of the crrimper facing the operator. Crimp the conductor tabs by squeezing the handles together until the jaws are fully closed or a sufficient crimp is obtained. (4) Move the lead to Anvil A. Place the insulating tab section on Anvil A. Crimp again Until the jaws are fully closed or a sufficient crimp is obtained. Contact Insertion into Molex Connector Housing (1) After the contact terminals have been installed on the wiring hamess, the contact terminals can be inserted into the proper location in the connector housing (PIN 030-01094-00XX). The terminal cannot be inserted upside down. Be sure to push the terminal all the way in, until a click can be felt or heard. (2) The self locking feature can be tested by gently pulling on the wire. Extraction of Contact from Molex Connector (1) Slip the flatnarrow blade of a Molex contact ejector tool, HT-1884 (BENDIX/KING PIN 047-05099-0001), under the contact on the mating side of the connector. By turning the connector upside down one can see the blade slide to the stop.
