- 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
RBP-7E
Ground Display Mode Program Pin (NO)
The T
3
CAS computer unit monitors this programming pin to select the TCAS
ground display mode while the aircraft is on the ground. If the aircraft is on the
ground and this pin is connected to program common (RBP-7K), TCAS goes into
standby mode. If this pin is left open and the aircraft is on the ground, TCAS
displays traffic only. Aural and voice annunciations are inhibited while the aircraft is
on the ground.
NOTE: TCAS does not display any traffic that it locates on the ground. TCAS
aircraft has WOW and intruder aircraft reports the same altitude or a lower
altitude.
RBP-7F
Display All Traffic Program Pin (NO)
The T
3
CAS computer unit monitors this program pin to select either the all traffic
display mode or the TA/RA only mode. If this pin is open, all traffic is displayed. If
this pin is connected to program common (RBP-7K), the TCAS displays only
TA/RA type intruders.
RBP-7G
Cable Delay Signal Program Pin (NO)
The cable delay program pins (RBP-7G, RBP-7H, and RBP-7J) convey to the
T
3
CAS computer unit the amount of delay differential between the top and bottom
antenna cables. Pin RBP-7G determines whether a time delay is added to the top
or bottom. If this pin is open, the time delay is added to the top. If this pin is ground
(connected to program pin RBP-7K), the time delay is added to the bottom. The
cable delay logic is given below. Program common for the cable delay program
pins is RBP-7K.
