Euronav products use a hardware dongle (a small electonic device
that has a unique electronic number) to meet the security requirements
of the chart data suppliers. Unlike other methods, this gives improved
reliability, and the ability to run the software on multiple computers,
such as one on the boat, one at home, by just moving the dongle
between the computers as required.
There are a number of dongle options:
As standard systems are shipped with a standard parallel
printer port dongle, when ordering you product you can request a
USB dongle as a no-cost option.
Generally the printer port dongle is more universal, but with most
computers being shipped with USB ports, this option is becoming
a more attractive one.
If you have a recent computer it may not have a printer port built
in, here you should order the USB dongle.
Similarly if you already have seaPro product, and upgrade your computer
to one that does not have a printer port, you can purchase a dongle
Other dongle options

a convienent solution as it can be permanently errantly left hidden

Note: For land based office use, charts have to be purchased for the
total number of possible concurrent users.
If you have purchased the plus product or above, you can purchase
a network dongle (printer port only) that will allow multiple copies
of the product to run across a local area network.
