The scanner consists of
- CCD Module section; where the 1500-pixel CCD sensor, illumination LED, light receiving lens and
illumination lens are mounted, and
- Main PCB; where the CPU (decode/communication controller which processes bar code signals are
combined), the power supply section that converts the main power to 3.3 V, the communication
interface section to output the decoded data, the indicators (buzzer / status LED)
The USB interface models are bus powered so no external power supply is needed, while the RS-
232C interface model needs a DC 4.5-5.5V power supply.
For the RS-232C model, make sure that the host device is powered off when connecting to the host
device and inserting.
