9-4 Updating the CDU Software via SUSI
9.2 Updating the CDU Software via SUSI
WARNING
Risk of misusage
Operating the NAVIKNOT system with a constantly muted CDU (jumper
removed from respective CDU PCB) voids the alert functionality of the
system resulting in unsafe and non conformable operability.
Removing the jumper to mute the CDU is ONLY allowed to
TEMPORARILY mute the system when in software update mode.
Always make sure that the jumper is installed again, when the software
update is finalized. Never operate the NAVIKNOT system with a con-
stantly muted CDU.
CAUTION
Risk of non-compliant System State / defective Alert Handling
Software update of the NAVIKNOT EU at least to version 3.000 and of all
installed CDUs at least to version
2.000 is mandatory for correct opera-
tion and alert handling of the NAVIKNOT system.
Operating the NAVIKNOT system with legacy software versions of the
NAVIKNOT EU and the CDUs (software mismatch) negatively impairs the
alert handling and causes non-compliance of the system.
Always make sure that the NAVIKNOT EU and CDUs are correctly
updated before operating the NAVIKNOT system.
Note
In case of Software Mismatch, the NAVIKNOT system is in non-compliant
system state and the alert handling is not operable.
The NAVIKNOT EU and all installed CDUs must correctly be updated
before operating the NAVIKNOT system again.
Proceeding with operating the NAVIKNOT system in a non-compliant
system state is not allowed.
CAUTION
Risk of inoperable device state through failure during software update
Updating software through SUSI‘s Flash Update mode is a risky opera-
tion, as SUSI writes directly to the device’s flash memory. Furthermore,
SUSI cannot verify whether the file supplied is indeed intended for the
device under service.Under adverse circumstances, a failure during the
update may leave the device in an inoperable state.
Never interrupt an update in progress once started.
CAUTION
Risk of inoperable device state through cable problems
Trying to execute the CDU software update with wrong or damaged RS-
232 connection cable will leave the CDU in an inoperable state.
The CDU software update can only be carried out with a special RS-232
connection cable, to connect to the receptacle on the CDU PCB.
Always check that the correct Sperry Marine cable is available and that
the cable is undamaged before executing the CDU software update.
Never execute the software update with wrong or damaged connection
cable. Never interrupt an update in progress once started.
