Project cables
The MF90 system is often a part of a project delivery. For such deliveries, specific
project cable drawings are established to show all the main cables, and how the various
products are connected. In such project cable drawings, the MF90 system cables
may be identified as
MF90/Cx
.
AC Power cables
Standard commercial AC mains power cables are used. Each cable is supplied
with the relevant unit. The typical length of a power cable is between 1.5 and 2.5
metres. If the power cable provided is too short you must use an extension cable (not
recommended), mount a new power outlet within range, or make your own power
cable with sufficient length.
C8 Ethernet cable
It is very important that a high-quality Ethernet cable is used. You must use Cat 5e STP
(Shielded Twisted Pair) quality or better. Using cables with lower bandwidth capacity
will reduce performance.
The maximum length of the Ethernet cable is 100 meters.
We strongly recommend that you install minimum two Ethernet cables between the
sonar room and the bridge. One cable is for operational use, while the other is spare.
C9 Video cable
This is a commercial cable. The display cable is often physically attached to the
display, and terminated in the “computer end” with a male connector. If the cable is
not attached, it is normally provided with the display. Keep the display cable as short
as possible. If the cable is too long, it may pick up electric noise, and this will reduce
the image quality. The graphic adapter on the Processor Unit provides several display
connectors. You can use one or two displays on your Processor Unit depending on
personal and/or operational preferences. With more than one display connected, use
the operating system functionality to control the presentations.
C13 Serial cable
If you wish to use RS-422 or RS-485 serial communication, use a cable with twisted
pairs. More than one serial line cable may be required to connect the computer to
external devices. To identify these cables, use postfix letters.
C27 Transducer cable
The transducer cable is part of the hull unit delivery.
C28 AC Power cable
This cable must be provided by the installation shipyard.
