Page 8: Introduction
This manual describes the physical, mechanical, and electrical characteristics and the installation requirements for the GPS 155XL/GNC 300XL Aviation Kit. After installation of the GPS 155XL/GNC 300XL system, FAA Form 337 must be completed by an appropriately certified agency to return the aircraft to service. -
Page 9: Interfaces
1.2.3 Interfaces The GPS 155XL/GNC 300XL provides an interface to various general aviation instruments. Table 3-2 defines the function of each pin on the 37-pin DSUB connector located at the back of the rack. Table 3-3 lists the function of each pin in the 26-pin HD-DSUB connector (J102) located above the 37-pin connector at the back of the rack. -
Page 10: J102 Connector Pin Functions
Remote Enter Input, when ground, functions the same as the enter key (Pin 26) on the GPS 155XL/GNC 300XL front panel. Sequence Hold Low Input, when grounded, activates HOLD mode. See GPS (Pin 13) 155XL Pilot’s Guide (GPN 190-00067-20) or the GNC 300XL Pilot's Guide (GPN 190-00067-30) for more information. -
Page 11: License Requirements
Unauthorized repairs or modifications could void your warranty and your authority to operate this device under Part 15 Regulations. The FCC requires GARMIN to inform users that these units meet the more stringent requirements "For Home or Office Use". -
Page 12: Limited Warranty
GARMIN Corporation warrants this product to be free from defects in materials and manufacture for one year from the date of purchase. GARMIN will, at its sole option, repair or replace any components that fail in normal use. Such repairs or replacement will be made at no charge to the customer for parts or labor. The customer is, however, responsible for any transportation costs. -

GPS Antenna Location The GPS 155XL/GNC 300XL GA 56 Antenna must be mounted on top of the aircraft. For best performance, select a location with an unobstructed view of the sky above the aircraft when in level flight. Figure 2-1 illustrates a typical GPS antenna installation. -

However, placement of the GNC 300XL GPS antenna relative to a COMM and COMM antenna, including its own, is critical. Figure 2-1. GPS Antenna Installation Considerations Use the following guidelines, in addition to others in this document, when locating the GPS 155XL/GNC 300XL and its antenna(s). •... -
Page 15: Rack Considerations
Check that there is ample space for the cabling and mating connectors. Avoid sharp bends in cabling, particularly the GNC 300XL COMM antenna cable, and routing near aircraft control cables. Cabling for the GPS 155XL/GNC 300XL should not be routed near components or cabling which are sources of electrical noise. Do not route the GNC 300XL COMM antenna cable near any ADF antenna cables. -
Page 16: Minimum Installation Requirements
The installer is advised to ensure that the switches and annunciators are the functional equivalent to and perform at least as well as the GARMIN devices used in the initial STC. The GARMIN switches and annunciators are sunlight readable and in the primary view of the pilot. Figure 2-2 shows what the GARMIN switch/annunciators look like. -
Page 17: External Altitude Input
Pressure altitude input from an external source may be derived from a RS-232 compatible serial altitude input or Parallel Gray Code/Gillham Altitude as described in Section 4 of this manual. Gillham Altitude is not required when serial altitude is used. Figure 2-2. Switch/Annunciator Layout GPS 155XL/GNC 300XL Installation Manual P/N 190-00067-22 Rev E Page 2-5... -
