- 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.

Designation
Functional Description
LMP-2
Bottom Antenna 90-Degree Port
J2 on the antenna is color-coded black. This antenna port (Note 2) is called the 90-
degree port because it produces a transmission pattern in the right-wing quadrant of
the aircraft. J2 is physically located toward the left wing of the aircraft when antenna
is properly installed. The TCAS function checks the built in dc-to-ground resistance
of this antenna port. It must detect approximately 8000 ohms or it reports antenna
test failure.
LMP-3
Bottom Antenna 180-Degree Port
J3 on the antenna is color-coded blue. Same as top antenna (Note 2) 180-degree
port (LTP-3).
LMP-4
Bottom Antenna 270-Degree Port
J4 on the antenna is color-coded red. This antenna port (Note 2) is called the 270-
degree port because it produces a transmission pattern in the left-wing quadrant of
the aircraft. J4 is physically located toward the right wing of the aircraft when
properly installed. The TCAS function checks the built in dc-to-ground resistance of
this antenna port. It must detect approximately 2000 ohms or it reports antenna test
failure.

CAS Computer Unit Left Bottom Plug (LBP)
LBP-1
115 V ac Power Input (H)
This pin along with the 115 V ac Power Input (C) line (pin LBP-7) provides the 115
V ac power requirements for the T
3
CAS computer unit.
Wiring requirement is a standard #20 AWG.
NOTE: The T
3
CAS computer unit operates with either 115 V ac, 400 Hz, or 28 V dc
input power. If 115 V ac is used, the power should be connected through a
3-A circuit breaker, and the pins for the ±28 V dc input should be left
unconnected.
