maintenance, etc., without losing a significant amount of time reprogramming ELTs.
3) If the ELT is not programmed with a 24-bit address location protocol, the Dongle will not reprogram the
ELT.
2. Operation
A. Operational Overview
1) Operation of the Dongle is automatic and requires no operator interface other than activating the +28
VDC power source and verifying no failure mode is present. See Fault Isolation on page 16.
2) The following conditions must be true for the Dongle to function:
a) +28 VDC aircraft power must be applied to the unit (i.e., the power source must be switched on).
b) The Artex ELT must be programmed with a 24-bit address long message (Standard Location
Protocol).
NOTE: The Dongle is designed for use only with Artex ELTs. No other use of the Dongle is
certified or approved by ACR Electronics.
c) The ELT software version must be at least V133M, V134B, or V135C (displayed on the ELT product
label).
3) Once the Dongle verifies or updates the ELT address, it shuts down.
