Comments
Some of the cables used by the echo sounder system require additional explanations and
recommendations.
Cable numbers
Cable numbers that are not used are spares for optional equipment and/or future
expansions.
Project cables
The echo sounder 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 echo
sounder system cables may be identified as
echo sounder/Cx
.
AC Power cables
Standard commercial AC mains cables are used. Each cable is supplied with the
relevant unit. The typical cable length is between 1,5 and 2 meters. If this 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.
C2
: This cable is only required if the Processor Unit operates from AC power.
C5 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.
C6 DC Power cable
This cable is only required if the Processor Unit operates from DC power.
C8 Ethernet cable
It is very important that high-quality Ethernet cables are used. You must use
Cat 5e STP (Shielded Twisted Pair) quality or better. Using cables with lower
bandwidth capacity will reduce performance. Do not make the connection using
the existing local area network (LAN). 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.
C10 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
