GTX 335R remote-mount Mode S ADS-B Out transponder 011-03301-00

011-03301-00 is the exact Part Number for this Garmin GTX 335R remote-mount Mode S ADS-B Out transponder. The unit provides remotely controlled Mode S transponder and 1090 MHz extended-squitter ADS-B Out operation. This card is tied to the photographed configuration and complete suffix, rather than serving as a generic listing for every GTX 335R version or a visually similar member of the same family.

The source listing identifies this exact Part Number 011-03301-00 as a TSO-approved GTX 335R ADS-B Out unit in serviceable condition. The photographed manufacturer plate confirms model GTX 335R, Part Number 011-03301-00, 14/28 V DC supply and photographed serial number 3EF020047. The source inventory record references a different serial, so allocation must be reconfirmed before order. The identification information is important because voltage, lighting, software, hardware options, certification and connector configuration can differ across related versions. The complete Part Number and the approved technical record must be checked together before purchase or installation.

Operational role and system function

The GTX 335R is installed remotely rather than controlled from its own cockpit faceplate. It receives control and aircraft data from compatible installed avionics, then transmits the required Mode S and ADS-B Out information through the approved transponder antenna. The unit is not a display and depends on correct external control, altitude and configuration inputs. In service, the unit depends on the integrity of its associated sensors, antennas, transceivers, control panels, displays, data buses, wiring, power and grounding. A reported fault at the unit can therefore originate elsewhere in the connected chain, and troubleshooting should follow the approved aircraft and equipment procedures.

The practical role of GTX 335R is to perform its defined function while exchanging required signals with compatible equipment. It cannot replace missing system components and should not be evaluated as an isolated consumer device. Controls or connectors visible in photographs do not prove that every possible function is enabled in a particular aircraft installation.

Installation and connected equipment

A complete installation requires the approved mounting rack or tray, connector and wiring, transponder antenna and coaxial cable, aircraft power and ground, pressure-altitude data, aircraft identity configuration and a compatible cockpit control source. GPS position-source requirements depend on the exact approved configuration and connected avionics. A rack, backplate, connector kit, antenna, wiring, cooling hardware or other accessories are not assumed to be included unless they are expressly listed in the quotation. Similar panel dimensions or family names do not prove electrical or approval compatibility.

Before installation, technicians should compare 011-03301-00 with the removed unit, aircraft equipment list, wiring diagrams, installation manual and modification records. Panel space, mounting depth, connector keying, pin allocation, circuit protection, lighting, ventilation, data format and configuration settings all require confirmation. Any substitution must be supported by approved data.

Configuration checks for 011-03301-00

The suffix in 011-03301-00 is part of the product identity. Software level, modification status, database requirements, embedded options, voltage and certification can affect compatibility even when two units look alike. These checks are especially important in aircraft that have accumulated supplemental approvals, avionics upgrades or wiring changes over time.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking features, controls, display or indicator face, fasteners and evidence of unauthorized modification. Functional testing should use the approved bench procedure for the exact model and suffix. Installation and return to service remain the responsibility of appropriately authorized personnel.

Serviceable condition, ordering and support

This 011-03301-00 GTX 335R is offered in Serviceable condition from partner stock with a six-month warranty. Partner stock should be reconfirmed at quotation because allocation can change. The available serial number, current test status and release documentation for the specific unit are confirmed before order acceptance.

For an inquiry, specify Part Number 011-03301-00, model GTX 335R, required quantity, destination and documentation requirements. Including the aircraft type and removed-unit Part Number helps prevent configuration errors. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Products shown there are related catalog positions, not interchangeable replacements unless approved technical data explicitly says so.
