11.4 Other SHORE connection controller functions
11.4.1 Ship-to-ship
A SHORE connection controller can be used to supply power to another ship using the ship-to-ship function. This may be useful
where quay space is limited.
The ship-to-ship function can be active in several SHORE connection controllers in the section at the same time. These ship-to-ship
functions operate independently.
Input
Assign the input under
Configure > Input/output
. Select the hardware module, then select the input to configure.
