Operating the PPT 2700
Scanning
The PPT 2700 has an integrated scanner which allows you to collect data by scanning 1 or 2
dimensional bar codes. See Appendix A, Demo Program for a sample scanning application.
To scan bar codes with the PPT 2700:
1. Aim the scan window at the bar code.
2. Press either the right, left, or center scan trigger. Make sure the red scan beam covers
the entire bar code. The green scan LED lights and a beep sounds to indicate a
successful decode.

Scanning PDF417 Bar Codes
The 2D scanning PPT 2700 terminal supports PDF417 bar code scanning. The raster pattern
has multiple scanning rows to accommodate the PDF417 symbol’s multiple rows.
1. Point the scanner at the bar code and press the trigger.
2. Center the aiming pattern (a spot or slab raster, as programmed) on the bar code.
3. As the raster pattern spreads, keep the pattern in the same horizontal plane as the
bar code.

4. The terminal indicates a successful scan by changing the LED from red to green,
beeping one or more times, and/or displaying the bar code data on the screen.
