Serial (RS-232) Connection

Reading Techniques

The view finder projects an aiming beam that should be centered over the bar code. (The 4820/4820i can be positioned in any direction for a good read.)

Hold the imager over the bar code, pull the trigger, and center the aiming beam on the bar code.

Center beam over bar code

4820/4820i can read in any direction

The aiming beam is smaller when

the imager is closer to the code and larger when it is farther from the code. Hold the imager close to smaller bar codes, and farther away from large bar codes to get a proper read.

If the bar code is highly reflective (e.g., laminated), you may need to tilt the imager at an angle so the bar code can be scanned.
