COMPONENT MAINTENANCE MANUAL
PART NUMBER 964-0452
DATE
INCORPORATED
Mar 30/01 The HFDR Software Mod 6 version contains cus-
tomer requested Red label changes to be used for
flight testing. HFDL SW Mod 6.
Mar 30/01 Converts the Transceivers to the production ver-
sion of PN 964-0452-012, which are HFDL Soft-
ware Mod 8.
Mar 30/01 Converts HF Transceivers with Honeywell propri-
etary HF Data Link (HFDL) protocol (PN
964-0452-022) to HF Transceivers, using the in-
dustry standard ARINC 635 HFDL protocol (PN
964-0452-012). HFDL SW Mod 8.
Mar 30/01 Changes the default date mode of operation of the
-0X2 Transceivers when both TP7G and MP2D
are grounded to Internal HFDL Data Mode instead
of defaulting to External Data Mode. This change
does not affect the voice mode of operation of any
of the radios. HW Mods 21 and 22.
Mar 30/01 Changes the Airborne Datalink Processor (ADP)
software to add the capability to display the ADP
and High Frequency Modem (HFM) software part
numbers on the ACARS/MCDU system and to fix
minor problems identified during testing of HFDL
Software Mod 8. HFDL SW Mod 9.
Mar 30/01 Reverts back to Software Version 1.70. Software
Version 1.80 introduced problems with sidetone
suppression during transmit operation. SW Ver.
1.70; HW Mod 22.
Mar 30/01 Incorporates changes to the Airborne Datalink Pro-
cessor (ADP) software requested by ARINC to
prevent the HFDL System from logging on to a
ground station when the ICAO address input from
the MODE-S transponder is missing, and readjusts
the data rate thresholds. HFDL SW Mod 10.
Mar 30/01 Allows the HF Transceivers and Control Panel to
be powered up in any sequence. Currently, the
"HFDR INSTALLED" discrete output of the HF Da-
ta Radio (or DOUT0 Spare Discrete OUT of A2
ADP board) is grounded on power up under soft-
ware control. The "HFDR INSTALLED" discrete
needs to be grounded on the A2 ADP board even
when power is OFF. HW Mod 23.
Mar 30/01 Incorporates changes to the Airborne Datalink Pro-
cessor (ADP) software to reduce/eliminate nui-
sance HFDR Faults (Fault Code 39) caused by in-
put power transients. HFDL SW Mod 5.
Mar 30/01 Incorporates minor changes to the Airborne
Datalink Processor (ADP) software requested by
ARINC to ensure that the Maximum Uplink Data
Rate recommended by the avionics to the HFDL
ground stations is a minimum of 300bps. HFDL
SW Mod 11.
