Power
The Handyscope HS5 is powered through the USB. If the USB cannot supply enough
power, it is possible to power the instrument externally. The Handyscope HS5
has two external power inputs located at the rear of the instrument: the dedi-
cated power connector and a pin of the 9 pin D-sub extension connector. The
specifications of the dedicated power connector are:
To power the instrument through the extension connector, the power has to be
applied to pin 7 of the extension connector. Pin 6 can be used as ground. The
following minimum and maximum voltages apply to the power inputs:
Note that the externally applied voltage should be higher than the USB voltage to
relieve the USB port.
