- 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.
- 4. For Flight Data Recording, the aircraft does not need to be in an on-ground configuration.

Connector
Pin
Designation
Functional Description
NOTE 1: Ground = Voltage of 0.0 V dc to +3.5 V dc or Resistance of less than 10 ohms applied
to input.
Open = Voltage of +18.5 to +36 V dc or Resistance greater than 100k ohms applied
to input.
NOTE 2: The Antenna Coax shall be RG225 or equivalent coaxial cable that provides a loss of
2.5 dB ±0.5 dB or less between the T
3
CAS computer and each TCAS Antenna port.
For Directional Antenna Coaxes, each coax cable must be within 0.5 dB of the other
coaxes (e.g., if one port has a 2-dB loss, the other 3 ports cannot exceed 2.5 dB loss).
NOTE 3: Ground = Port capable of sinking at least 20 mA of current.
Open = Voltage of +18.5 to +36 V dc or Resistance greater than 100k ohms applied
to output.
NOTE 4: Refer to the applicable Interface Control Documents (ICD) for corresponding labels
associated with each bus and label bit definition.
NOTE 5: The Mode S address bits are set to 1 if the address bit pins are connected to RTP-15E,
and set to 0 if the address bit pin is left open.
NOTE 6: The pins RTP-8C/8D define the SDI Pin Programming for the position of the internal
transponder. These pins are for encoding the location of the Mark 4 transponder in the
aircraft, (i.e., “system number”) per Section 2.1.4. of ARINC Specification 429. Refer to
Table 4-37.
NOTE 7: Landing Gear Override applies to Part No.-11801 and -55801. For other Part No.RTP-
10J is defined as Steep Approach.
