SYSTEM DESCRIPTION, INSTALLATION, AND MAINTENANCE MANUAL
ASPIRE-400
(2) During application mode and if ORT directed, the ACD holds the Non- Safety Channel
Card in reset.
(3) The ACD sends an IP address to the Channel Card Side B with the following
characteristics valid IP address is selected at random from private IP address range
10.0.0.0 to 10.255.255.255
(4) When ORT configured, the ACD processor sends the following configuration information
to the Non-Safety Channel Card HDR Mode.
D. CFDS to SDU - Fixed Format Labels
(1) The ACD receives the following fixed format ARINC-429 Broadcast Data labels that are
ORTenabled, on the "Data from CFDS" bus for logging purposes and any additional
purposes as indicated, with a period of 900 ms to 1.1 s for each label:
(a) Label 125 UTC (BCD)
(b) Label 150 UTC (Binary)
(c) Label 260 Date
(d) Label 126 Flight Phase (for Air/Ground determination) with ORT determined
content
(e) Labels 233-237 Flight Number
(f) Labels 301-304 A/C identification (tail number).
NOTES:
1 Absence of these labels does not prevent SDU operation.
2 Only some aircraft CFDS use Label 237 as part of the Flight Number
communication.
3 Only some aircraft CFDS use Label 304 as part of the A/C IDENT
communication.
E. Configuration Reporting via Transmitting Protocol Encapsulating Labels
(1) Protocol Encapsulating labels are used to exchange data between the SDU and the
CFDS where the labels' content contains different content for the same label number.
(2) In order to accommodate the transmission of a record of data to the CFDS, multiple
Protocol Encapsulating labels may be sent.
(3) One or more records may be sent in a block.
NOTES:
1 Where messages are to be displayed on the CFDS screen a record equates to a
line and a block equates to a page and only displayable ISO 5 characters are
sent.
2 Some CFDS expect records to contain all binary.
(4) When ORT selected to CFDS Type 1, the ACD transmits SATCOM LRU Configuration
Display Data to the CFDS in blocks of Label 356 Configuration Block on the "Data to
CFDS" interface using the following words:
(a) STX
(b) SYN
(c) Data
