Problem
Diagnostic Tips
USB is not working
Unless you use USB plus power, you
need a separate power connection
to the
unit
like the external
power
supply.
Restart the
unit
by temporarily
disconnecting the power. This may
help the POS system to detect the
unit
. The very first time the PC
might
install some general drivers,
possibly
from your computer setup
CD.
In case of KB emulation you can
select various ‘keyboard languages’
or the universal ‘Alt-input-method’.
In a windows environment verify with
the device manager that a HID
(Human Interface Device) is installed
for the
unit
.
Ensure that both the
unit
and
POS-
system/Computer expect the
same
USB protocol (KB emulation,
RS-232
emulation or IBM POS
protocol).
See Configuration Manual for setup
codes and reset (re-power) the
unit
after making any changes.
