- 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 4-5: ACSS 41-Pin VSI/TRA Interface Descriptions (cont)
Connector Pin
Designation
Functional Description
J1-18
PRESSURE TRANSDUCER MODULE POWER OUTPUT (COMMON):
An optional ACSS PTM may be used in an installation to supply ARINC
429 vertical speed information to the VSI/TRA. Pins 18, 19, and 20
supply input power to the PTM. Pin J1-18 is the power return pin and is
connected to PTM pin 8.
J1-19
PRESSURE TRANSDUCER MODULE -15-V dc POWER OUTPUT:
See pin 18. Connects to PTM pin 11.
J1-20
PRESSURE TRANSDUCER MODULE +15-V dc POWER OUTPUT:
See pin 18. Connects to PTM pin 5.
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/TRA back lighting via a remote light sensor already present in some
aircraft (Douglas and Boeing). The VSI/TRA has its own built-in sensor
and therefore a remote light sensor need not be used in all installations.
Program the VSI/TRA for a remote light sensor, as described under pin
34.
J1-26
ARINC 429 (A) TCAS TA/RA DATA INPUT:
Traffic and Resolution Advisory data is supplied to the VSI/TRA from the
TCAS computer unit via this high-speed ARINC 429 data bus. Paired
with pin 11.
J1-27
ARINC 429 (A) VERTICAL SPEED NO.1 INPUT:
This is the primary ARINC 429 input bus to the VSI/TRA. This pin
accepts high- or low-speed ARINC 429 vertical speed data (Label 212).
Its use is determined by the source select discrete and configuration
straps CS0 and CS1 (pins 31, 32, and 33 respectively).
Paired with pin 12.
J1-29
TA/RA VALID DISCRETE OUTPUT (NO):
This output discrete indicates the ability of the VSI/TRA to perform as a
resolution advisory and/or a traffic advisory display. If the VSI/TRA fails,
this discrete presents an open. Normal operation causes a ground. This
discrete is monitored by the TCAS computer unit.
