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 26.
(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 Cobham Artex ELT must be programmed with a 24-bit address long message
(Standard Location Protocol).
NOTE: The Dongle is designed for use only with Cobham Artex ELTs. No other use of
the Dongle is certified or approved by Cobham.
(c) The ELT software version must be V133M, V134B, or V135C (displayed on the ELT
product label).
(3) Once the Dongle verifies or updates the ELT address, it shuts down.
