Software Start-up
Each ECDIS-E panel PC is equipped with a device called a Security Block
(sometimes called a `dongle') which is attached to a USB port on the PC.
On start-up, the system compares permit codes and the product type
identifier stored in the dongle to the corresponding data in the system
configuration file. If the data does not match, the system will not be
authorized and will run in a degraded state. For further information, see
System Security.
Starting up the software takes approximately 1 minute. Soon after the
system is powered up the VisionMaster FT Start Up window appears on the
screen, this window shows the current system software version number,
copywrite information and a status bar displaying the system loading
status.
After system initialisation has completed the start up window is replaced by
the VisionMaster ECDIS-E display. By default the system opens with
ownship symbol shown in the centre of the display.
