Colour display
A commercial colour display is used with the Simrad ME70 system.
Note that the colour display is not a standard part of the ME70 delivery.
Processor Unit
The ME70 Processor Unit is a high performance
marine table top computer. The computer is based on
a commercial design, but the software and hardware
has been specified and assembled by Simrad to suit
the ME70 requirements.
The computer is supplied with Microsoft ® Windows ® 7 operating system. It provides
multiple interfaces for communication with relevant pheripheral devices.
The Processor Unit communicates with the Ethernet switch in the Transceiver Unit by
means of two high speed Ethernet cables.
Transceiver Unit
The Simrad ME70 Transceiver Unit is housed in a 19” instrument rack. In order to
reduce the loss in the transducer cables, the transceiver is physically located as close as
possible to the transducer. The transceiver computes and generates the electric signals
sent to the transducer to form a transmission - a ‘ping’. Following the transmission, the
transceiver receives the echoes. These are filtered and amplified, and then converted to
digital format.
The main components in the transceiver are:
• Three transceiver subracks with a total of 25 transceiver circuit boards
• One Ethernet switch
• One cabinet fan unit
