EK60/C15 Universal Serial Bus (USB) interface
Most computers support one or more USB connectors for peripheral devices. In a
typical echo sounder configuration, the USB connectors are not used. However,
a USB interface may be used to accept serial line information (providing a
converter is used). You can also use the USB interfaces to connect a mouse,
keyboard, printer or memory devices. The number of USB sockets available
depends on your computer make and model.

EK60/C18 FireWire interface
Most current computers have a FireWire interface. This interface is however not
required by the echo sounder system.

EK60/C20 Remote control of GPT power
The General Purpose Transceiver (GPT) allows you to design a simple box
with a separate on/off switch for the transceiver. An on/off switch will prevent
the transceiver from being powered up constantly. Some commercial displays
provide this functionality by means of a "Remote" connector on the rear side. The
GPT unit is switched off when pin 23 on the "Auxiliary" connector is grounded to
pin 22. If more than one GPT is used in a system, a single switch can be used to
switch all the transceivers on and off simultaneously. To achieve this, pin 23 on
all the "Auxiliary" connectors are connected to one of the switch terminals, while
pin 22 on all the connectors are connected to the other terminal. This method will
however not allow you to reset a single transceiver. You must also ensure that this
wiring does not create a ground loop.
Both this cable and the box must be supplied by the installation shipyard.
Do not use the spare wires in the Ethernet cable to provide the remote control
facility!

C21
EK60/C21 GPT interface to external synchronisation
This cable is used to connect the General Purpose Transceiver (GPT) to an
external system in order to provide transmission control (synchronisation). This
is a very useful feature if you have other hydroacoustic systems on board. If
more than one General Purpose Transceiver (GPT) is used by the ES70, the
