5. Return to Service Test
Any time a TCAS LRU is removed and replaced following repair or maintenance, a return to
service test is required. The System Self−Test procedures referenced in paragraph 4.A. are
sufficient to check all system parameters.
6. Operational Software Loading Using an ARINC Portable Data Loader
When updating the TCAS 3000 Computer Unit with an ARINC portable data loader PDL,
verify the current TCAS 3000 Computer Unit software part number prior to continuing for
cockpit system only.
A. Current Software Verification
NOTE: Software verification using cockpit systems ONLY.
Verify the current software part number according to the extended maintenance
capabilities on status page code 0000 in the FAULT ISOLATION section of this manual or
the individual aircraft maintenance manual (refer to the onboard maintenance system
program).
B. Operational Software Loading (While Installed on Aircraft)
(1) Verify that the system inputs for AIR/GROUND (RMP−5K) and GEAR UP/DOWN
(RMP−13F) are grounded.
(2) Obtain an ARINC PDL and the appropriate interface cable for connecting the data
loader to the J1 (front) connector of the TCAS 3000 Computer Unit.
The following PDLs have been tested and found to be satisfactory for performing this
task:
• DEMO Systems − Part No. 30100 (Revision A and later versions)
• Teledyne − Part No. 2230915−01−D
• SFIM − Part No. YV68A110.
Other part numbers from these suppliers and ARINC 615 data loaders from other
manufacturers may perform the task successfully. However, ACSS can not verify
their usability.
(3) Shut off the PDL and remove power from the TCAS 3000 Computer Unit. Connect
the cable between the PDL and the J1 front connector on the TCAS 3000 Computer
Unit.
(4) Apply power to the TCAS 3000 Computer Unit.
(5) Turn on the PDL.
(6) Obtain the operational software. Insert disk No. 1 of the operational software into the
PDL for program uploading (or follow the applicable instructions for the PDL).
