- 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.

Table 4-6: ACSS 55-Pin VSI/TRA Interface Descriptions (cont)
Connector Pin
Designation
Functional Description
J1-36
CONFIGURATION STRAP #4 INPUT (NO):
For -84X units, CS4 is paired with CS3 to program the Range Format.
See pin 35.
For -86X, -88X, and -89X units, CS4 is paired with CS5 to program the
Display Format. See pin 17.
J1-37
CONFIGURATION STRAP COMMON INPUT:
This pin is the return line for the configuration strapping pins J1-17, 18,
19, 22, and J1-32 thru 36. The VSI/TRA uses 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 (J1-37).
J1-38
115-V ac, 400-HZ POWER INPUT (COMMON):
See pin 40. Connect to aircraft ac ground.
J1-40
115-V ac, 400-HZ POWER INPUT (HIGH):
This pin, along with its return line (pin 38) supplies power to the
VSI/TRA. Connect power through a 1-A circuit breaker.
J1-42, 43
5-V LAMP-DIMMINGINPUT: (J1-42 LOW, J1-43 HIGH)
The VSI/TRA monitors the cockpit lamp voltage bus at pins 42 and 43.
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.
J1-47, 48
ARINC 429 VERTICAL SPEED NO.1 BUS INPUT: [J1-47 (A), J1-48
(B)]
This differential pair input is a low-speed bus (12.5k bits/second
nominal) that receives ARINC 429 vertical speed data from the primary
(#1) digital ADC or the #1 PTM.
J1-49
VERTICAL SPEED VALID DISCRETE OUTPUT:
This discrete output sends bootstrap ARINC 565 vertical speed valid
data to the cross-side display. The output is connected to the Vertical
Speed Valid Input (pin J1-5) of the cross-side display.
J1-50
PRESSURE TRANSDUCER MODULE -15-V dc POWER OUTPUT:
An optional ACSS PTM may be used in an installation to supply vertical
speed information to the VSI/TRA. Pins 50, 51, and 52 supply input
power to the PTM. Pin J1-50 is the -15-V dc output pin and is connected
to PTM pin 11.
J1-51
PRESSURE TRANSDUCER MODULE POWER OUTPUT (COMMON):
Connects to PTM pin 8. See pin 50.
