- 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.

Table 4-5: ACSS 41-Pin VSI/TRA Interface Descriptions (cont)
Connector Pin
Designation
Functional Description
J1-5
VERTICAL SPEED 26 V ac, 400-HZ REFERENCE INPUT (HI):
See pins 4 and 16.
J1-8
VERTICAL SPEED 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 the ADC. This pin is only
used when pins (1, 2, 3) or (4, 5, 6, and 16) are used. Also see pins 1
and 4.
J1-9, 10
5-V LAMP-DIMMINGINPUT: (J1-9 LOW, J1-10 HIGH)
The VSI/TRA monitors the cockpit lamp voltage bus at pins 9 and 10.
This voltage may be either ac or dc. The back lighting in the VSI/TRA is
adjusted by and tracks this voltage from 0.5 V to 5 V. If this input falls
below 0.5 V or is absent, the VSI/TRA sets itself to a nominal level to
prevent the display from going dark due to loss or failure of the lamp-
dimming bus.
J1-11
ARINC 429 (B) TCAS TA/RA DATA BUS INPUT:
Paired with pin 26. These pins connect to a TCAS computer unit.
J1-12
ARINC 429 (B) VERTICAL SPEED NO.1 INPUT BUS:
Paired with pin 27. These pins connect to Digital ADC No.1 or PTM No
1.
J1-14
ARINC 429 (B) VERTICAL SPEED NO.2 INPUT:
Paired with pin 30. These pins connect to Digital ADC No.2 or PTM
No.2.
J1-15
CONFIGURATION STRAP COMMON INPUT:
This pin is the return line for the configuration strapping pins J1-17, J1-
32 thru 38, andJ1-41.
J1-16
VERTICAL SPEED 26 V ac, 400-HZ REFERENCE INPUT (LO):
See pins 4 and 5.
J1-17
CONFIGURATION STRAP #3 INPUT (NO):
The VSI/TRA utilizes configuration strapping so unique aspects of any
given installation may be identified and its functions supported. Each
configuration strap (CS), and its associated function, becomes active
when connected to program common, (J1-15). The inactive state of CS3
is open. This pin is monitored but unused in the -84X units. In -86X units
it is paired with pin J1-34 (CS2) to configure the Lighting Curve and in -
88X and -89X units it is paired with pin J1-41 (CS8) to select the desired
Filter Time Constant. See pins 34 and 41.
