1.GENERAL DESCRIPTION

1.1INTRODUCTION

This manual provides the installation and operating instructions for the GARMIN GTX 327 Digital Display Transponder system. Information pertaining to the maintenance, alignment, and procurement of replacement parts is found in the GTX 327 Maintenance Manual, P/N 190-00187-05.

1.2EQUIPMENT DESCRIPTION

The GARMIN GTX 327 is a panel-mounted transponder with the addition of timing functions. The transponder is a radio transmitter and receiver that operates on radar frequencies, receiving ground radar interrogations at 1030 MHz and transmitting a coded response of pulses to ground-based radar on a frequency of 1090 MHz.

As with other Mode A/Mode C transponders, the GTX 327 replies with any one of 4,096 codes, which differ in the position and number of pulses transmitted. By replying to ground transmissions, the GTX 327 enables ATC to display aircraft identification, altitude and groundspeed on ATC radar screens. The GTX 327 is equipped with IDENT capability that activates the Special Position Identification (SPI) pulse for 18 seconds.

The GTX 327 is configured with all key controls. The layout of the front panel keys and displays segregates the transponder’s primary functions from the secondary timing functions. The unit can be configured so the aircraft avionics master bus can turn the unit on.

1.3INTERFACE SUMMARY

The GTX 327 provides the following interface connections via the rear connector:

∙Ten (10) encoding altimeter inputs.

∙External IDENT input.

∙External STBY input.

∙External suppression pulse input.

∙Switched power output of up to 1.5 amps (for digital altitude encoder power).

∙Aircraft power input (11 to 33 volts).

∙Aircraft dimming buss input voltage.

∙Aircraft master switch turn-on option.

∙Serial altitude input.

∙Serial altitude output.
