Receiver Unit description

The EM 712 Receiver Unit has all receive electronics, like control processor, amplifiers,
Analog-to-Digital Converters, power supply and Ethernet interface.
The Receiver Unit is a small wall-mounted steel
cabinet with integrated shock and vibration absorbers,
designed for bulkhead mounting. The number of circuit
boards in the Receiver Unit will depend on the chosen
transducer configuration. Twisted pair Ethernet is used
for data communication with the Processing Unit.
The Receiver Unit is normally located in a "sonar
room" close to the transducer arrays.
For a 0.5° transducer array, two Receiver Units are
used.
With EM 712B it is possible to upgrade EM 710 to
EM 712 without replacing the transducer modules. To
achieve this we have made a separate Receiver Unit
scientifically tailored for use with the EM 710 receive
transducers. The EM 712B Receiver Unit has the same
measurements and weight as the regular Receiver Unit.
