- 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.

Functional Description
RTP-15F
APM Clock
This is the APM Clock Output which is used to synchronize serial output to the
APM. The Clock output frequency is 2.0 MHz + 1% when the APM is being
accessed and is set to a logic 0 (not toggling) when the APM is not being accessed.
Connect to APM J1-2.
RTP-15G
APM Serial Data Output
This is the Serial Data Output from T
3
CAS to the APM Serial Data Input. APM
Enable (RTP-15J) and APM Write Enable (RTP-15K) must be enabled before data
can be written to the APM. Connect to APM J1-1.
RTP-15H
APM Serial Data Input
This is the Serial Data Input to T
3
CAS from the APM Serial Data Output. APM
Enable (RTP-15J) must be enabled before data can be read from the APM. Connect
to APM J1-9.
RTP-15J
APM Enable No.1
This pin is used to Enable Read/Write access to the APM. An APM Enable Output
logic of 1 disables Read/Write access to the APM and a logic 0 enables APM
Read/Write access. Connect to APM J1-3. This pin is used in conjunction with pins
RTP-15G (APM serial output) and RTP-15H (APM serial input).
RTP-15K
APM Write Enable No.1
This pin is used to Enable Write access to the APM. An APM Write Enable Output
logic of 1 disables Write access to the APM and a logic 0 enables APM Write
access. Connect to APM J1-4. This pin is used in conjunction with pin RTP-15G
(APM serial output).

This output is a ground/open-type discrete used by the weather radar display to
place the radar in standby mode. A ground on this pin enables the weather radar
display.
