Power Options

SM7201
(5VDC USB Only)

The
SM7201
is powered from the host via the USB host cable and is ready to scan when connected. USB power is via Standard USB (5VDC) or USB BC1.2. It does not have an on/off switch.

SM7208
(Multi-Interface)

The
SM7208
is powered from the host via the host cable and is ready to scan when connected.  USB power is via Standard USB (5VDC), USB BC1.2 or USB Power Plus.   
Use of auxiliary scanner and/or color camera options supported on the
SM7208
require more than 500mA. This can be achieved via an external 12VDC power supply, 12VDC PowerPlus USB cable, or a high-power USB port such as USB BC1.2 compatible.  Depending on the host, some BC1.2 compatible high-power USB ports still may not provide enough power.  In this case an external 12VDC power supply is needed.
