- 1. Obtain a New or Blank Compact Flash (CF) card.
- 2. Copy to the New or Blank CF card the appropriate ‘Header File’
- a) Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.
- b) Header files needed to download Maintenance Data, Event Data and CRC Part Numbers can be obtained from ACSS Customer Services at +1-623-445-7070 or crc.acss@l-3com.com.
- 3. For downloading Maintenance Data, Event Data or CRC Part Numbers the aircraft does not need to be in an on-ground configuration.
- 4. Apply power to the computer unit.
- 5. Insert the CF card.
- 6. For ACSS part numbers 9005000-10000, -10101, -10202, and -10204 the DATA STATUS LED will UblinkU green once; this indicates the unit recognized that a CF card was inserted.
- 7. For ACSS part numbers 9005000-11203, -11801 and -55801 the DATA STATUS LED will UblinkU green while reading the header file and performing the action defined in the header file.
- 8. Flight Data Recording
- 1. T3CAS part numbers 9005000-10000, -10101, -10202, and -10204 only support FAT16 CF card formatting. T3CAS part numbers 9005000-11203, -11801 and -55801 support both FAT16 and FAT32 CF card formatting.
- B. Flight Data
- 1. Obtain a New or Blank CF Card.
- 2. Copy to the New or Blank CF Card the Appropriate Header File.
- 3. Header files are files copied to the New or Blank CF card that will instruct the computer unit what is desired to be downloaded.
- 4. For Flight Data Recording, the aircraft does not need to be in an on-ground configuration.

SYSTEM DESCRIPTION AND INSTALLATION MANUAL
T
3
CAS/Part No.9005000
(c) RS-422 Signals
The T
3
CAS card has an RS-422 Input bus which is multiplexed on the
same pins as an ARINC 429 Input bus. The RS-422 Input Bus meets the
electrical requirements in EIA/TIA-422-B.
The RS-422 Input Bus has an input impedance on each pin relative to
ground of ≥ 9k ohms and a differential input impedance between + and -
pins of ≥ 9k ohms.
NOTE:
This is due to the fact the input is multiplexed with an ARINC
429 Receiver.
The RS-422 Output Bus has an output impedance of 75 ±5 ohms
distributed equally between the + and - outputs.
(d) GPS Time Mark
The GPS Time Mark Input accepts RS-422 GPS Time Mark signals from
an ARINC-743A GPS.
The GPS Time Mark Output is used to provide an accurate timing
reference for GPS signals. The output has a differential RS-422 signal
format.
(4) Programmable Discrete Input/Output Pins
The Discrete signals addressed in this section are APM/ASDB
programmable input and output signals as shown in Table 4-12, Table
4-13, and Table 4-14. As new Aircraft configurations/ASDBs are defined,
the Discrete signals will be assigned to a particular input/output per
Appendix n (“n” denotes Appendix’ that are created as new Aircraft
Configurations are defined).
