NOTE
To avoid electromagnetic interference when the scanner is connected to a
CBX connection box, verify the jumper positions in the CBX as indicated in
its Installation Manual.
3.1 POWER SUPPLY
Power can be supplied to the scanner through the CBX100/500 spring clamp terminal pins
as shown in Figure 15:

The power must be between 20 and 30 Vdc only. The max. power consumption is 30 W
including startup current.
Several accessory power supplies are available to power the DS8100A(s) and reading
station components. See par. 1.8.
A security system allows the laser to activate only once the motor has reached the correct
rotational speed; consequently, the laser beam is generated after a slight delay from the
power on of the scanner.
It is recommended to connect the device CHASSIS to earth ground (Earth) by setting the
appropriate jumper in the CBX connection box. See the CBX Installation Manual for details.
3.2 MAIN SERIAL INTERFACE
The main serial interface is compatible with the following electrical standards and the relative
signals are available on the CBX spring clamp terminal blocks:
RS232
RS485 full-duplex
RS485 half-duplex
The main interface type and the relative parameters (baud rate, data bits, etc.) can be
set using the Genius™ utility program or the Genius™ based Host Mode Programming
procedure. For more details refer to the section "Main Serial Port" in the Genius™
Help On Line.
