5.1 Concerns for Pin Connection
Connect the connection cables, and then install the main board in the ultrasound system. If you
install the main board before connecting the cables, it is impossible to connect USB cable to
the VBF board, connect ECG cable to the VHV board, main board fan to the power supply and
connect two power cordes to the VHV board.
SATA cable is used to connect hard disk and drive, and interfaces of SATA, hard disk and CD-
ROM are fragile and easily damaged. Handle them with care.
Ensure the startup switch is connected correctly to the main board. Otherwise, the ultrasound
system cannot be started up.
The connection of IO board cables are complex, take attentions when connecting them.
Otherwise, the ultrasound system may result in malfunction.
