7.3 USB hardware keys
The USB hardware key contains the USERPERMIT for the charts. If no hardware key is inserted, it
is not possible to view imported charts. The hardware key can be used in two configuration types.
Stand-alone configuration and Cluster configuration
7.3.1 Stand-alone configuration
Stand-alone configuration is used if only one ECDIS is installed. In this configuration the USB
hardware key exclusively controls the USERPERMIT in the ECDIS. If the hardware key is replaced
with another hardware key, the ECDIS adopts the USERPERMIT from the new hardware key. This
will render the installed charts and permits useless, and new chart permits must be installed.
7.3.2 Cluster configuration
Cluster configuration is used when more than one ECDIS is installed. In this configuration one of
the USB hardware keys is selected as the primary key. The remaining ECDIS will adopt
USERPERMIT from the primary hardware key. It is possible later on to change which hardware
key is the primary key. This is probably undesirable as it will render the installed charts and permits
useless, and new chart permits must be installed.
If the primary USB hardware key is removed or becomes faulty, the remaining ECDIS in the cluster
continues to work and uses the primary key‘s USERPERMIT for a period of 3 months. A faulty
primary USB hardware key must be replaced as soon as possible to ensure continued operation of
the ECDIS.
7.4 Install software update
The software for the ECDIS may need to be updated.
Section 7.5 “Software Version”
describes
how to verify if a newer software version is available.
IMPORTANT: Only install updates when in Port. Installation of software updates while at
sea may compromise the operational safety of the vessel.
To install a software update open the management menu and select “Software Update”
Select the installation packet (.mbp). The packet can be loaded from an USB stick.
