DESCRIPTION AND OPERATION
1. Description
A. Functional Overview
1) The Dongle is connected to an ELT to allow the operator to easily program aircraft 24-bit address
(Standard Location Protocol) into a compatible ELT.
2) When power is applied, the Dongle verifies the 24-bit address set locally on its DIP switches matches the
24-bit address stored in the memory of the ELT when power is applied. If the Dongle address matches
the ELT address, the Dongle will shut down. If the ELT address does not match, the Dongle will
program the ELT with its locally set address, and then shut down.
B. Components
1) The Dongle is designed to mount to a protective top cover on the ELT with four screws. See Figure 2
DGL-1 (Dongle) Programming Adapter Assembly.
Figure 2 DGL-1 (Dongle) Programming Adapter Assembly
2) The Dongle can be mounted directly to the airframe within the proximity of the ELT to utilize the
prefabricated cable assembly (P/N 611-4010).
C. 24-Bit Address Reprogramming Functionality
CAUTION: THE PROGRAMMING AND LABELING OF THE ELT MUST MATCH THE
AIRCRAFT IN WHICH IT IS INSTALLED. RE-MARK THE ELT PRODUCT LABEL
AS NECESSARY TO REFLECT NEW PROGRAMMING AND/OR COUNTRY OR
REGISTRY. CONTACT THE LOCAL REGULATORY AUTHORITIES
RESPONSIBLE FOR ELT REGISTRATION AND REFER TO THE APPLICABLE
ELT DESCRIPTION, OPERATION, INSTALLATION AND MAINTENANCE
MANUAL FOR ELT REGISTRATION REQUIREMENTS.

INSTALLATION
1. Regulatory Requirements and Guidelines
A. Applicability
1) The regulatory requirements and guidelines for ELT installations discussed in the following subtasks are
applicable to installation of the DGL-1 Dongle Programming Adapter and must be applied to the DGL-1
Dongle Programming Adapter. Where the word “ELT” is used in the following subtasks, read “DGL-1
Dongle Programming Adapter”.
B. TSO C126, Paragraph D
1) TSO approval of the ELT does not constitute installation approval. All installations are subject to field
approval for a given airframe by either an approved FAA DER or FAA FSDO. For installations outside the
US, contact your local civil aviation regulatory agency for details.
C. FAA
1) This manual constitutes supporting data, as described in AC43.9-1, Paragraph 6.h.(2) and AC 43-210,
Chapter 2, Paragraph 201(a)(6), and as such may be used as support for FAA field approval of the
ELT/NAV Interface installation.
2) In addition to the procedures outlined herein and in accordance with FAR Part 43, the installer must
adhere to the aircraft manufacturer’s instructions and recommendations and the guidelines provided by
FAA Advisory Circular AC 43.13-2 “Acceptable Methods, Techniques, and Practices - Aircraft
Alterations”, specifically Chapters 1 through 3, 11, and 13.
3) By signing the aircraft logbook, and FAA Form 337, the installer is stating the installation has been
performed in accordance with current FAR requirements and the procedures outlined herein. The
completed Form 337 is provided to the FAA and also becomes a permanent part of the aircraft
maintenance records in accordance with AC43-9, Paragraph 17.
D. Canada
1) All installations must be performed in accordance with Canadian Aviation Regulations (CAR) Part V,
Subparts 37, 51, and 71.
E. Other Countries
1) Installations in aircraft outside of the United States and Canada must be performed in accordance with

F. RTCA
1) DO-204, § 3.1.8 guidelines for mounting a ELT:
a) The ELT shall be mounted to primary aircraft load carrying structures, such as trusses, bulkheads,
longerons, spars, or floor beams.
b) The mounts shall have a maximum static local deflection no greater than 0.1 inches (2.5 mm) when
a force of 100 lbs (450 newtons) is applied to the mount in the most flexible direction. Deflection
measurements shall be made with reference to another part of the aircraft not less than 1 foot (0.3
meters) nor more than 3 feet (1.0 meters) from the mounting location.
2) DO-182, § 6.2.2.b recommends that:
a) To maximize the probability of the ELT transmitting a detectable signal after a crash, all ELT system
components, which must survive a crash intact, e.g., transmitter and external antenna, should be
attached to the airframe in such a manner that the attachment system can support a 100 g load,
(ELT weight x 100, ELT antenna weight x 100, etc.) applied through the center of gravity of the
component (ELT, antenna, etc.) in the plus and minus directions of the three principal axes of the
aircraft.
b) Post-crash critical components of the ELT system, e.g., transmitter and external antenna, should be
mounted as close to each other as possible.
2. Mechanical
A. Dongle Location
CAUTION: AVOID INSTALLING THE DONGLE WHERE IT MAY BE SUBJECTED TO
UNPROTECTED EXPOSURE TO HARSH CHEMICAL FLUIDS, SUCH AS
DEICING COMPOUNDS. THESE TYPES OF CHEMICALS MAY CAUSE DAMAGE
TO FASTENERS AND ELECTRICAL COMPONENTS, AS WELL AS ELECTRICAL
CONNECTOR CORROSION.
1) Mount the Dongle within 2 feet (610 mm) of the ELT, such that the interface harness does not exceed
3 feet (914 mm) including strain relief.
2) The Dongle chassis and ELT are mounted to the same support structure in most installations.
B. Dongle Installation
1) Coordinate the Dongle installation with the ELT installation whenever possible. If the Dongle is an
add-on to an existing ELT installation, extend/modify the existing ELT support structure to
accommodate the Dongle.
2) See Figure 4 Dongle Outline and Dimensions.
Figure 4 Dongle Outline and Dimensions
3) Mount the Dongle on the protective top cover on the ELT with four screws (P/N 201-6324-01)
4) Test the ELT installation in accordance with Test and Fault Isolation on page 14.
