NAVIKNOT 600 SD 056353/J
Updating the CDU Software via SUSI 9-5
In case of bugfix releases or software improvements which require a
software update of existing CDUs, Sperry Marine will provide the
required Sperry Universal Service Instrument (SUSI) application
together with the update files in one zipfile.
The zipfile „SUSI.zip file including updates“ is available via download
for authorized field service personnel from the Sperry Marine Extranet.
The software update of the CDU can only be carried out via an RS-232
connection. A special cable is required to connect to the receptacle on
the CDU PCB (J5 = CDU 5001; J2 = CDU 5002). The ready made cable is
available from Sperry Marine under Stock No. 022939.
For the update of the CDU software, it is mandatory to have the SUSI
application installed on a PC or laptop.
The required update files from Sperry Marine must be downloaded and
stored at a convenient location on the same PC or laptop where the
SUSI application is installed.

If you have not yet installed SUSI, refer first to the SUSI Installation
Guide, Sperry document no. 056358, before proceeding with the
update procedure below.
Update Procedure
Note For software update of the NAVIKNOT system components, the correct
sequence of update procedures is mandatory:
- In case the installed CDUs DO NOT have the MOST CURRENT SW ver-
sion, the Software of the CDUs must ALWAYS be updated before the EU
software.
- In case the installed CDUs already DO have the MOST CURRENT SW
version, only the Software of the EU must be updated.
CAUTION
Risk of loss of parameter settings through software update
It cannot be guaranteed that parameters settings in the User and Setup
menus and the currently active manual settings are left intact during the
software download.
Before exchanging the flashboard or performing a software update via
SUSI, record all settings to be able to re-enter them manually, if required.
Note For recording all parameter settings see “Setup and Configuration
Tables” in the appendix of this manual.
1. Make sure that you have installed the SUSI application on a PC or
laptop, downloaded and stored the required update files on the PC/
laptop and that you have obtained the required special RS-232 con-
nection cable from Sperry Marine, before proceeding with the proce-
dure.
2. Power down the NAVIKNOT 600 SD system.
3. Get access to the CDU and remove the back cover.
