Power
The scanner requires a minimum of 2.5W at 5 VDC power.
The interface cable that comes with the scanner supports
both direct power (where the scanner takes power from the
host machine) and external power (that’s what the supplied
power adapter is for). A sufficiently robust POS system
can support a scanner successfully without external power;
a POS system with a barely adequate power supply may
produce erratic performance (either of the POS system
itself, or of the scanner, or both) when a scanner is attached.
Unless you are sure your POS system can candle such
loading, it is recommended that you use the supplied power
adapter. When an external adapter is connected, the
scanner does not take power from the host.
The scanner turns on when power is supplied, and turns off
when power is removed. There is no on/off switch on the
scanner itself.
Use only an AC/DC power adapter approved for the
scanner. Use of other power supplies may cause damage
to the scanner, and void the factory warranty.
