Connecting Optional Power Supply
Some terminal interfaces require an external power
supply. One end connects to a standard AC
receptacle supplying the appropriate voltage level.
The other end plugs into a receptacle located on the
housing connector of the wedge interface cable.
CAUTION:
!
The Catalog No. 2755-PW1 Power Supply
has the following polarity:
+5 V
If using another power supply, the polarity
must be the same.
To install the power supply:
1. Power to the terminal must be turned off.
CAUTION:
Do not connect power supply until the
!
terminal is turned off. Failure to follow
this caution could result in damage to the
scanner or terminal.
2. Plug the circular connector of the power supply
into the receptacle on the housing connector of
the wedge interface cable.
3. Plug the power supply into a standard AC
power source.
Terminal Power Up Sequence
Turn on the power to the terminal to which the
scanner is connected. The unit will issue a series of
beeps which are intentional and indicate that the
terminal/keyboard power-on reset routines have
been completed.
