3.1.10.4

24-Bit Address Installation Test (mandatory for Installations
reprogramming by Ameri-King’s authorized dealer):


Verify the 24 Bit Address by using the ELT Computer Test Set TS-451. The 15 digit
hex code shall be extracted by using the Computer Test Set or equivalent. Realize that
the AK-451 transmits a 406 MHz test message, which is encoded such that it will be
ignored by the SAR satellite system. This 15-digit number is used to register the ELT
with the appropriate 406 MHz ELT registration authority. In the US, the National
Oceanic and Atmospheric Administration (NOAA) maintains the database of
registered ELT's.

Note: Although a typical 15 digit hex code can contain position data, the 15-digit
ID used for registration purposes shall contain the "default' value of no position
data instead (this is indicated by the last 5 digits of the 15 digit hex code being
"FFBFF").

3.1.10.5

GPS Position Test, (if equipped)
(for using TS-451 Computer Test Set only) :


This test must be conducted inside a RF shielded room or an ELT RF shielded box.
Connect the AK-451 with ELT Computer Test Set TS-451.

Turn the switch of the ELT to “ON” position.
Verify the following setting (See Figure 20.) From the Hyper Terminal window (or
the equivalent RS-232 window), Click File -> Properties -> Settings tab. Click OK to
go back to Hyper Terminal window.

Waiting for 50s, verify the 36 Hex digits (ignore first 6 digits). The last 30 Hex digits
will be used for Cospas-Sarsat Decode program, in order to see the Latitude,
Longitude Position.

Note:
When used with ELT's that are programmed for Standard Location 24 bit protocol,
the ELT to be program itself to the aircraft's 24 bit address. This feature will allow
the ELT to be transferred between aircraft. Re-register the ELT with the Search and
Rescue authority is required. This makes maintenance of the ELT a simple matter of
replacing the ELT. Note: There is no electronic connection between TCAS or Mode S
systems and the ELT, only the ID number is common.
