- 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.

Connector Pin
Designation
Functional Description
J1-4
BOOTSTRAP REFERENCE OUTPUT:
This output sends the bootstrap ARINC 565 ac reference voltage to the
cross-side display. The output is connected to the Secondary 26-V ac
Reference Input (pin 7) of the cross-side display.
J1-5
VERTICAL SPEED NO.2 VALID DISCRETE INPUT:
This discrete input receives bootstrap ARINC 565 vertical speed valid
data from the cross-side display. The input is connected to the Vertical
Speed Output (pin 49) of the cross-side display.
J1-7
SECONDARY 26-V ac REFERENCE INPUT:
This input receives the bootstrap ARINC 565 ac reference voltage from
the cross-side display. The input is connected to the Bootstrap
Reference Output (pin 40) of the cross-side display.
J1-8
VERTICAL SPEED +dc REFERENCE INPUT:
See pin 2.
J1-9
PRIMARY VERTICAL SPEED 26-V ac, 400-HZ REFERENCE INPUT:
See pins 10, 11.
J1-12
VERTICAL SPEED NO.1 VALID DISCRETE INPUT:
The VSI/TRA 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 ADC #1. This pin is only
used when pins ( 2, 3, 8) or (9, 10, 11) are used and on the #1 VSI/TRA
display. Also see pins 2, 10, and 11.
J1-13,14
R/C BOOTSTRAP OUTPUT: [J1-14 (HI), J1-13 (LO)]
This two-wire bus output sends ARINC 565 vertical speed data to the
cross-side display when the bootstrap mode is activated. These pins are
connected to the ARINC 565 Secondary Vertical Speed Input bus on the
cross-side display as follows:
J1-14 of the on-side display is connected to J1-6 of the cross-side
display.
J1-13 of the on-side display is connected to J1-1 of the cross-side
display.
J1-15
BOOTSTRAP COMMAND OUTPUT:
This pin is connected to the Source Select #2 (SS2) discrete input, pin
29, within the VSI/TRA. The output provides an Open/28 V dc discrete
that can be used to annunciate the bootstrap function. This output is
normally not used.
