    BENDIX/KING KLN 94 SECTION IV THEORY OF OPERATION GENERAL INFORMATION 4.1.1 GENERAL DESCRIPTION The KLN 94 is a panel-mounted, long range, GPS based airborne navigation system with a data- base. The KLN 94 provides VFR, IFR enroute, terminal and non-precision approach functions. The KLN 94 is certified to TSO C129a.

The power supply uses a flyback converter circuit to transform the aircraft power bus voltage (11-33 volts) into the required voltages for the KLN 94’s internal circuitry.

  • Page 20 BENDIX/KING KLN 94 DETAILED CIRCUIT THEORY 4.3.1 POWER BOARD 4.3.1.1 General Refer to Figure 4-2 and Power Board section of the Illustrated Parts List as an aid for the following discussion. The KLN 94 power supply produces the +5.0V, +9V, -12V, +13V, -15V, and +20V (V_LCD_DRIVE) DC voltages.
  • Page 21 BENDIX/KING KLN 94 4.3.1.2.4 ON/OFF Control The On/Off Control circuit monitors the signal from the front panel On/Off switch (PWR_SW_LO), the avionics power bus (AIRCRAFT_POWER_MONITOR), and the microprocessor-controlled shutdown line (POWER_SHUTDOWNn). If these inputs allow the unit to turn on, the On/Off Con- trol circuit outputs an active-low ENABLEn signal.
  • Page 22 BENDIX/KING KLN 94 Soft start and shutdown control is provided by CR6025 which serves to hold the COMP output (Pin 1) of U6002 low to delay startup or initiate shutdown. Undervoltage shutdown is generated by U6003-B pulling pin 1 (COMP) of U6002 to ground. This occurs when V_IN falls below 7.2V. If this happens, R6067 provides hysteresis to prevent restart until INT_AC_PWR has returned to at least +9.0V.
  • Page 23 BENDIX/KING KLN 94 4.3.1.3.8 Power Interrupt Switch The Power Interrupt Switch provides the control logic and power switches to turn on the Capacitor Backup circuit during power interrupt. U6003-A senses the output voltage from the Input Hash Filter and compares it to a reference voltage that is generated by U6002 pin 14 (5V_LVPS_REF). R6060 provides about 0.7V of hysteresis.
  • Page 24 BENDIX/KING KLN 94 If too much current flows, R6037 will begin to turn on Q6011 which then cuts back gate drive to Q6009-B, thereby limiting the current. When the unit is turned off, the +5V power applied to the gate of Q6010 will be so low that Q6010 will be off.
  • Page 25 BENDIX/KING KLN 94 At power down, the reset controller’s output pin, U6004-1, goes low immediately after a dip in the +5V supply is detected. When it goes low, Q6017 stops conducting which causes Q6020 to stop conducting. Resistor R6057 bleeds down the level of the LCD Bias Supply at least as quickly as the +5V supply voltage falls.
  • Page 26 BENDIX/KING KLN 94 4.3.3 GPS XPRESS RECEIVER CAUTION DO NOT ATTEMPT TO ALIGN OR REPAIR THE GPS PXPRESS RECEIVER BOARD (P/N 200–08825–0001). THIS BOARD IS NOT A FIELD SERVICEABLE ASSEMBLY The GPS Receiver Board, operating in conjunction with the KA 92 antenna provides the Host mi- croprocessor (on the Main board) with position, velocity, and time information through the RS-232 interface module.

    BENDIX/KING KLN 94 4.3.4.2.7 Graphics Microprocessor The Graphics microprocessor handles two main functions within the KLN 94. The first function is the interface to the LCD display. The majority of the data shown on the display is generated from the Host Microprocessor and passed to the Graphics microprocessor via the Dual Port SRAM (U5008).

    BENDIX/KING KLN 94 LABEL DESCRIPTION G_WDTOUT Goes high when internal watchdog times out. INT0 CF_READY Goes high when the Compact Flash card is ready for the next data transfer. INT1 CF_PRESENT Goes high when the Compact Flash card is inserted into the socket.
  • Page 31 BENDIX/KING KLN 94 During program and erasing of the flash memory devices, a VPP of +5VDC will be supplied to the VPP signal line by U5003 pin 13 when HW_PGM_EN is pulled high by the U5029 decode logic device. This is done one of two ways, either when a programming adapter is connected to the J5102 JTAG port connector or by pressing the CURSOR and ENT keys simultaneously on the front panel at the time power is applied to the unit.
  • Page 32 BENDIX/KING KLN 94 4.3.4.2.12.2.2 Generation of control signals for buffering and multiplexing of the 386EX data bus, PERIPH_BUS, and CF_BUS. This avoids PERIPH bus contention with a possible previous PERIPH read operation. 4.3.4.2.12.2.3 Generation of customized RDn and WRn signals for PERIPH_BUS and CF_BUS accesses.
  • Page 33 BENDIX/KING KLN 94 4.3.4.2.12.3 Main EPLD Functionality The Main logic is spread across three EPLDs identified as MAIN1 (U5029), MAIN2 (U5041), and MAIN3 (U5023) on the schematic. Refer to other sections of this document for discussion of spe- cific functions assigned to the MAIN EPLDs. The following paragraphs give an overview of the functions.
  • Page 34 BENDIX/KING KLN 94 The DISCRETE_CS2n signal will be asserted low when the MAIN_DISCRETE_CSn is low, the MAIN_ADDRESS_BUS1 is high, and the other two MAIN_ADDRESS_BUS signals are low. 4.3.4.2.12.5 Main 2 EPLD Controller The MAIN2 EPLD controller holds the Display Video decoding, Audio Tone/Clock Generator, and some discrete line decoding.
  • Page 35 BENDIX/KING KLN 94 Three 8 bit latches are connected to the microprocessor data bus. An independent DISCRETE_CSn signal for each latch is controlled by the WRn signal. If WRn is low and the ap- propriate DISCRETE_CSn signal is low, the data from the DATA_BUS will be latched to the ap- propriate output pin.
  • Page 36 BENDIX/KING KLN 94 CR5015 removes its negative cycle before the internal ADC of the Host microprocessor samples it. Q5021 and R5180 are used to select the bias of the input signal. The bias is currently set to 0V. 4.3.4.2.17 Dimming Pot control The DIM_POT_SENSE circuitry consist of a 5VREF signal at one input to the pot.
  • Page 37: Peripheral Chip Selects

    BENDIX/KING KLN 94 This limits the sinking current of Q5013-B to approximately 350mA. When pin 15 of U5013 is low, Q5013-B will be turned off. 4.3.4.2.23 DUART and RS-232 Interface DUART U5042 provides two asynchronous receiver-transmitters. It is used for serial communica- tion between the Host microprocessor and the GPS PXpress Card Receiver.
  • Page 38 BENDIX/KING KLN 94 U5043-C and U5043-D are connected to the external lighting bus signals LIGHTING_28V_LO and LIGHTING_14V. The inverting summing amplifier U5043-D uses R5201, R5122, and R5107 to scale the voltage. U5043-C filters and inverts the DC voltage level so the Host microprocessor can use this voltage to control the intensity of the button and nomenclature backlighting LEDs.
  • Page 39 BENDIX/KING KLN 94 Level shifter transistors Q5008 and Q5011 permit the standard 5V logic of the Host microproces- sor to connect the drive transistors to the -12V supply rail during the active low state. Resistors R5136, R5140, R5006, R5141, R5145, R5147 and R5146 supply the needed bias currents. Clamp transistor Q5005 is turned on by the GRAPHICS_RESET signal to prevent bursts of light during that period of start-up when the microprocessor is not initialized.
