- 7. Downloading Information from the TP3PCAS Using a CF Card
- 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.

CONFIGURATION STRAP #8 INPUT (NO):
For -84X and -86X units, CS8 is not used and pin J1-22 must remain
Open.
For -88X and -89X units, CS8 is paired with CS3 (pin 35) to program the
Filter Time

REMOTE LIGHT SENSOR INPUT: (J1-23 HIGH, J1-24 LOW )
This input at pins 23 and 24 provides a means of controlling the
VSI/TRA back lighting via a remote light sensor already present in some
aircraft (Douglas and Boeing). The VSI/TRA has its own built-in sensor
and therefore a remote light sensor need not be used in all installations.
Program the VSI/TRA for a remote light sensor, as described under pin
34 and 35.
J1-25, 44
ARINC 429 TCAS BUS INPUT: [J1-25 (A), J1-44 (B)]
This differential pair input is a high-speed ARINC 429 bus (100k
bit/second nominal) that receives Traffic and Resolution Advisory data
supplied by the TCAS computer unit.
J1-26, 45
ARINC 429 VERTICAL SPEED NO.2 BUS INPUT: [J1-26 (A), J1-45
(B)]
This differential pair input is a low-speed bus (12.5k bits/second
nominal) that receives ARINC 429 vertical speed data from the
secondary (#2) digital ADC or the #2 PTM.
J1-27, 46
ARINC 429 INERTIAL REFERENCE SYSTEM BUS INPUT: [J1-27 (A),
J1-46 (B)]
This differential pair input is a low-speed ARINC 429 bus (12.5k
bits/second nominal) that receives vertical speed data from an Inertial
Reference System.
J1-28
RA VALID DISCRETE OUTPUT:
This output discrete indicates the ability of the VSI/TRA to perform as a
resolution advisory and/or a traffic advisory display. If the VSI/TRA fails,
this discrete presents an open. Normal operation causes a ground. This
discrete is monitored by the TCAS computer unit.
