(3) Software Verification Using a Software Verification Fixture ONLY
NOTE: Software versions prior to Change 7 can not be displayed on the Software
Verification Fixture.
(a) Obtain Software Verification Fixture (Part No. T326948901) with associated
adapter cable (Part No. 200F00084).
(b) Remove power to the TCAS 3000 Computer Unit.
(c) Connect the adapter cable (Part No. 200F00084) to the TCAS 3000 Computer
Unit and the software verification fixture.
(d) Apply power to the TCAS 3000 Computer Unit.
(e) Enable the software verification fixture and verify the appropriate software part
number is displayed in the 15digit display.
(f) Perform a TCAS system selftest and verify that TCAS TEST PASS is
annunciated.
NOTE: The TCAS TEST FAIL message may be annunciated if an LRU that
supplies input to the TCAS 3000 Computer Unit is not powered on.
(g) If the software part number is not displayed, repeat step (a) thru step (f).
(4) Software Verification Using a Remote Connected VSI/TRA ONLY
On some aircraft configurations, software verification may be performed using a
remote connected VSI/TRA (Part No. 4067241861, 862, or 863) display attached
through adapter cable (Part No. 200F00083) to the J1 front connector of the TCAS
3000 Computer Unit during the extended test mode.
Verify the particular aircraft configuration can support a cockpit initiated selftest and
be recognized at the 8second time period after activation.
NOTE: CMC/CFDS activated selftest will not be recognized at the 8second time
period, only an approved TCAS control panel.
