- 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.

CONFIGURATION STRAP #3 INPUT (NO):
Pin 17 is used in conjunction with pin 35 to select the indicator operating mode as
follows:
The following applies: O = Open, G = Ground.

J1-18
SECONDARY VERT SPEED VALIDITY INPUT (+28 V dc):
The VSI-TCAS receives a +28-V dc signal from an ARINC 575 or 565 air data
computer indicating its valid operation. An “open” at this pin indicates an invalid
vertical speed signal from the ADC. This pin is only used when pins (1, 2, 3) or (4,
5, 6, and 16) are used.
J1-19, 20
VERT SPEED BOOTSTRAP ac OUT: (J1-19 [HIGH], J1-20 [LO])
This output repeats the ARINC 565 input signals (26-V 400-Hz reference and
signal) available on the primary input when this input has been selected :
-26-V 400-Hz reference
The voltage available on the output (26-V ac Bootstrap ref. output) is the same as
that available on the 26-V ac 400-Hz reference (hot) of the ARINC 565 primary
input, the common reference being the cold of the 26-V ac primary ref. input.
- Output signal (vertical speed bootstrap ac output) available on two wires (HI and
LO).
J1-22
CHASSIS GROUND INPUT:
Connected to aircraft frame. Also used to connect ARINC cable shields to the
chassis.
J1-23
115-V ac, 400-HZ POWER INPUT (COMMON):
See pin 40. Connect to aircraft ac ground.
J1-24, 25
REMOTE LIGHT SENSOR INPUT: (J1-24 LOW, J1-25 HIGH)
This input at pins 24 and 25 provides a means of controlling the VSI-TCAS back
lighting via a remote light sensor already present in some aircraft (Douglas and
Boeing). The VSI-TCAS has its own built-in sensor and therefore a remote light
sensor need not be used in all installations. Program the VSI-TCAS for a remote
light sensor, as describe under pin 34.
