Simrad EK80 Installation Manual
For "slave" operation, a remote system (for example K-Sync) must be available to
provide trigger pulses. For "master" operation, a remote hydroacoustic system (sonar,
echo sounder) is connected. This remote system must be set up in "slave" mode.
You must be equipped with a standard set of tools. This tool set must comprise the
normal tools for electronic and electromechanical tasks. This includes different
screwdriver types, pliers, spanners, a cable stripper, a soldering iron, etc. Each tool
must be provided in various sizes. We recommend that all tools are demagnetized to
protect your equipment.
Context
Whenever more than one hydroacoustic system is installed on a vessel, interference may
occur. To avoid interference, you have these options:
• The systems are all connected to a common synchronization system.
• One of the acoustic systems is set up as "master", and controls the transmissions on
the other systems.
The EK80 offers functionality for remote transmit synchronization. It can be set up to
operate in either Master or Slave mode.
Tip
The Wide Band Transceiver (WBT) offers an
synchronisation purposes. This synchronization method may be more stable that the
traditional CTS/RTS connection to a serial port.

Procedure
1 Connect the synchronization cable from the remote system to an available
communication port on your Processor Unit.
This is described in the Cable layout and interconnections chapter. Observe the
applicable requirements related to cabling. Make sure that the total length of the
serial line cable does not exceed approximately 50 meters. If a longer cable is
required, you may need to use buffer amplifiers.
If the Processor Unit is not fitted with a suitable serial line connector, use a
USB-to-serial converter. Several types are commercially available. Note that most
USB-to-serial converters will introduce some latency. They may also introduce
be jitter in the communication. The amount of jitter depends on the quality of
the converter.
