5.2.13.1 US TAIL and Hex ADDRESS Entry Pages
For first time turn-on, proceed to step 5. Otherwise begin at step 1, with the unit turned off:
1. To enter the configuration pages, press and hold the FUNC key while powering on the unit.
2. Power the unit on by pressing the ON, ALT, or STBY key or turn on with the avionics master
switch (while holding the FUNC key). The unit performs a self-test routine and displays a "Jump
to Diagnostics" page.
3. Navigate to the address entry page by repeatedly
pressing the FUNC Key.
a. The page that appears is either ADDRESS US TAIL#
N _ _ _ _ _ .
b. Or ADDRESS HEX _ _ _ _ _ _ .
NOTE
It is not necessary for the installer to convert a US aircraft registration number
(N-number) to a Hex address. The GTX 330 converts the US registration number to
hexadecimal automatically.
4. To select between Hex or Tail number, press the CRSR key, then 8 or 9 key to move to the correct
selection.
5. For entering either the address hex code or the US registration number, press the CRSR key 1 time.
(This highlights the address field).
6. Enter the aircraft address using the number keys. Press a key repeatedly to scroll through the digit/
alpha characters for that key.
7. Press the CRSR key to select the next numeric entry field. Enter the next character as stated in the
previous step, then move onto the next one, repeating the process until the complete number is
entered.
8. When finished, press the CRSR key to accept the number entry.
9. Using the FUNC and/or START/STOP keys, toggle through the pages to get off of, then back onto
the aircraft address page. Verify that the address is correct.
The unit now contains a Mode S address and may be turned off. To power the unit on in the normal mode,
press only the ON, ALT, or STBY key (without holding the FUNC key) or turn on with the avionics
master switch.
