C8
EK60/C08 Computer to ground
When applicable, this cable must be provided by the installation shipyard. It is
a standard commercial ground cable.

C9
EK60/C09 Ethernet to ship local area network (LAN)
If the computer is equipped with two Ethernet connectors, it may also be
connected to the local area network (LAN). A standard "straight" Ethernet cable
is required, and the cable must be provided by the installation shipyard.
Note that screened Ethernet (CAT5 or better) cables must be used.

C10
EK60/C10 Ethernet to General Purpose Transceiver (GPT)
It is strongly recommended to equip the computer with two network adapters.
One will be used to communicate with the General Purpose Transceiver(s),
while the other is used to connect the ES70 system to the local area network.
Failure to use separate network adapters will cause a heavy traffic load on the
common network. This will inhibit normal traffic on this network, and degrade
the operational capabilities of the echo sounder system.
With one transceiver, use a "crossover" Ethernet cable between the computer
and the transceiver.
With more than one transceivers, add an Ethernet switch to the system, and use
"straight" Ethernet cables.
It is very important that high quality (CAT5 or better) Ethernet cables are used.
Cables with lower bandwidth capacity will reduce the system performance.

C11
EK60/C11 Serial interface line
The number of serial lines available depends on the chosen computer make and
model. The Simrad MC71 computer provided with the EK60 provides five serial
lines, four of these are optically isolated. Additional serial lines may be added if
required. A multiple interface circuit board is used, and the connector requires
a special adapter.
One serial line can be used to provide external synchronisation with other
hydroacoustic systems (sonars, echo sounders). If this option is used, the
synchronisation cable to the General Purpose Transceiver (GPT) is not used.
