Mindray DC-70T Service Manual

4-2 Product Principle
 As the independent sub-module, 4D driving function and physiological signals are
subordinate to the engine board.
 As an option, CW receiving function can be realized through an independent single board
and is subordinate to TRA board signal.
 Back-end unit: more functions are achieved on back-end unit. It basically resembles with PC. It
is equipped with main functions of the main unit, calculation capacity of image post-process,
operator-system interface to human-computer interaction, etc. PC module takes charge of
back-end unit. The elements are shown above.
 Power supply unit: it supplies the power to the front-end unit, back-end unit and peripherals.
Other elements are shown above.
 PHV module is subordinate to DC-DC module.
 DC-DC module includes DC-DC board and battery assembly.
 AC module includes AC-DC, AC interface, etc.

Front-end unit mainly consists of:
 Engine board
 TR board
 Probe board
 CW mini board
 4D board
The engine board takes charge of the front-end unit and controls each module of the front-end
control.
