  • Page 11: General Description

    Garmin 400 Series/500 Series units. The GTX 330 is configured with all key controls. The layout of the front panel keys and displays segregates the transponder’s primary functions from the secondary functions. The unit can be configured so the aircraft avionics master bus can turn the unit on.

  • Page 12: Tis System Capabilities

    TIS SYSTEM CAPABILITIES The GTX 330 also provides uplink information such as Traffic Information Service (TIS). TIS is a ground-based service providing relative location of all ATCRBS Mode A and Mode C transponder equipped aircraft within a specified service volume.
  • Page 13 No further wiring or configuration programming is required for the unit. Note that BDS (3,0) is only required for transponders compatible with ACAS/TCAS II. The GTX 330 does not support BDS (3,0).

  • Page 22: Cooling Air

    The GTX 330 meets all applicable TSO requirements without forced air-cooling. The application of forced air cooling to the rear air nozzle of the GTX 330 is highly recommended to provide beneficial cooling to the unit. The GTX 330 was designed to handle a constant interrogation of 450 Pulse Repetition Frequency (PRF) per second, with short periods of 1200 PRF.

  • Page 23: Installation Procedure

    (see Figure 4-1). The card-edge connector may be used to terminate shield grounds to the GTX 330 back plate. Table 4-1 lists the electrical connections of all input and output signals. Figures in Appendix C identify the cable requirements for each signal. Required connector and associated hardware are supplied in the connector kit (P/N 011-00583-00).

    NOTES 1. Insertion/extraction tools from ITT Cannon are all plastic; others are plastic with metal tip. Non-Garmin part numbers shown are not maintained by Garmin and consequently are subject to change without notice. 3. All wires must be passed through the backshell before being assembled to connector.

    Figures C-2 and C-3 for parallel gray code and Figure C-3 for serial data altitude interconnections. Carefully check encoder input lines for correct connection after wiring is complete. NOTES The GTX 330 contains internal altitude code line isolation diodes to prevent the unit from pulling the encoder lines to ground when the transponder is turned off.

  • Page 29: Altimeter Interconnect, Dual Gtx 330 Installation

    RS-232 serial data input as shown in Figure 4-2. If transponder number 2 is a Garmin GTX 327, connect the RS-232 output from the altitude encoder to J3271 pin 19 (refer to GTX 327 Transponder Installation Manual, P/N 190-00187-02).

  • Page 30: Discrete Functions

    SELECT is grounded, ARINC 429 OUT PORT 1 remains active, while PORT 2 is inactive. When TIS CONNECT SELECT is inactive (“Standby” is displayed on the 400/500 Series units) the GTX 330 logs onto TIS service when a momentary ground is applied to P3301-46. When TIS is active, a momentary ground logs off of TIS service.

  • Page 31: Serial Data Electrical Characteristics

    ARINC 429 data concentrator. Since the Garmin 400/500 Series products have only two ARINC 429 input ports, the GTX 330 manages support for several equipment interfaces. The GTX 330 has four ARINC 429 input ports, making it capable of taking altitude, air data, heading, EFIS selected course and possible future features, and then concentrating it on the ARINC 429 OUT 2 port.

  • Page 32: Rs-232 Input/Output, Software Update Connections

    TCAD/TCAS, both systems cannot be connected to the same 400/500 Series unit to display traffic simultaneously. In a multiple traffic system/multiple 400/500 Series unit installation, connect ARINC 429 CHANNEL 1 from the GTX 330 to only one of the 400/500 Series units and ARINC 429 CHANNEL 2 to the other 400/500 Series unit.

  • Page 33: Arinc 429 Input/Output

    EXTERNAL STANDBY SELECT input is active for only one of the two GTX 330s at any given time. The GTX 330 ARINC 429 Output 1 port is active when J3301 pin 13 is grounded [EXTERNAL STANDBY SELECT (remote STANDBY)]. In installations having a transponder combination of GTX 330/GTX 327 (or GTX 330/other transponder), the GARMIN and GARMIN W/TIS formats from the ARINC 429 Output 1 port, J3301 pins 34 and 37, are available if the GTX 330 has SW 3.03 and above.

  • Page 35: Post Installation Configuration And Checkout Procedure

    POST INSTALLATION CONFIGURATION AND CHECKOUT PROCEDURE Perhaps the most important factor in the GTX 330 transponder configuration and checkout is the Mode S address entry. Refer to paragraph 5.2.12 for Mode S address entry pages. CAUTION Be sure to check all aircraft control movements before flight is attempted to insure that the wiring harness does not touch any moving part.

    DISPLAY page does not appear to the pilot. MAN (Manual) Display backlighting is controlled manually by the pilot on the GTX 330 DISPLAY page. No backlight parameters can be entered when the manual mode is selected. LVL (Level) Shows the current level of display backlighting, based on the lighting input source (lighting bus voltage, or the ambient light if the source is PHOTO) and the settings on this configuration page.

  • Page 43: Key Lighting Page

    NOTE If a lighting bus (any selection other than PHOTO) is selected, and the lighting bus control is turned to its minimum (daytime) setting, the display brightness tracks the GTX 330 photocell. SLOPE (Auto Only) Sets the sensitivity of the display brightness to changes in the input level. The higher the number, the brighter the display for a given increase in the input level.
  • Page 44 DEFAULT. Key lighting level is determined by the ambient light PHOTO (Photocell) level as measured by the photocell on the GTX 330. Backlight level tracks a 14 volt DC aircraft lighting bus. Backlight level tracks a 28 volt DC aircraft lighting bus.
