GTX 330DES Mode S diversity transponder — 011-00455-70

011-00455-70 identifies this Garmin GTX 330DES Mode S diversity transponder. The unit provides Mode S surveillance replies, altitude reporting and Extended Squitter capability in an approved dual-antenna installation. This card is based on the exact partner inventory record and the complete designation shown above; it is not a generic listing for every visually similar version in the same equipment family.

The partner source describes the item as: Mode S digital transponder with Level 2 datalink with Antenna Diversity Extended Squitter “ES” versions available for ADS-B Out capability Altitude monitor Dedicated VFR button allows for quick and easy 1200/VFR squawking TSO’d. The source condition is Serviceable. Technical statements in this listing are limited to the exact functions and characteristics documented for this position. Unknown dimensions, current consumption, pin assignments or aircraft applicability are not inferred from a related model.

Operational role and system function

GTX 330DES is a panel-mounted transponder with antenna diversity. It uses top and bottom antenna paths as required by the approved installation and can support ADS-B Out when the aircraft configuration, approved position source and software meet the applicable requirements. In normal service, correct operation also depends on the associated antennas, sensors, control heads, displays, power, grounding and wiring that belong to the approved aircraft installation. A fault indication at one component does not by itself prove that the component is the source of the system fault.

The equipment must be evaluated as part of its complete signal chain. Controls, connectors or labels visible in a photograph confirm physical features of the photographed configuration, but they do not prove that optional functions, software features or approvals are enabled in a particular aircraft. Approved technical data remains the controlling reference.

Installation and connected equipment

Installation requires approved transponder antennas and coaxial cables, an altitude source, aircraft power, suppression and data wiring, and an approved GPS position source where ADS-B Out is configured. A rack, backplate, connector kit, antenna, coupler, wiring harness or other installation hardware is not assumed to be included unless it is explicitly named in the quotation or Delivery Set.

Before installation, technicians should compare 011-00455-70 with the removed unit, aircraft equipment list, wiring diagram, modification status and applicable manufacturer manual. Panel dimensions, mounting depth, connector keying, pin allocation, circuit protection, lighting, cooling, data format and configuration settings all require confirmation. Similar appearance is not evidence of interchangeability.

Configuration checks for 011-00455-70

The complete designation and suffix are part of the product identity. Hardware revision, modification status, voltage, lighting, software, database, certification and connector configuration can differ between closely related variants. These details should be confirmed against the aircraft records and the specific serial number allocated for supply.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking features, controls, display or indicator face, fasteners and evidence of unauthorized modification. The inspection should also confirm that shipping protection and supplied accessories agree with the quotation. Functional testing should follow the approved bench procedure for the exact model. Installation and return to service remain the responsibility of appropriately authorized personnel.

Serviceable condition, ordering and support

This 011-00455-70 GTX 330DES is offered in Serviceable condition from Partner Stock with a six-month warranty. Partner availability can change, so allocation, the available serial number, current test status and release documentation are reconfirmed before order acceptance. Image processing does not alter or upgrade the declared commercial condition.

For an inquiry, specify 011-00455-70, model GTX 330DES, quantity, destination and documentation requirements. Adding the aircraft type, removed-unit Part Number and installation details helps prevent configuration errors. Buyers may also request current photographs of the allocated serial number and clarification of the quoted delivery set before confirming the order. Packaging and transport arrangements are selected for the destination and the physical characteristics of the unit.
