Bar Code Specifications
The HP-75D and the bar code software is designed for use with the HP 92267A and HP 92267B Digital
Bar Code Wands. However, you can use any wand that has all of the following:
• Three-pin Hypertronics DO 1 connector
• Operation on a single 5-volt power supply
• Digital output compatible with TTL and CMOS.
• Signal polarity: high on non -reflective, low on reflective
• Less than 50 rna peak current
Switched wands are recommended for use with the HP-7 5D in order to conserve battery life.
The bar code software will reliably decode bar code with these specifications:
• Minimum element width (high resolution wand) of 0.005 in (0. 13 mm)
• Minimum element width (medium resolution wand) of 0.0075 in (0. 19 mm)
• Ratio of wide to narrow elements between 2: 1 and 3: 1
• Minimum scan speed of 3 in/s (7.6 cm/s)
• Maximum scan speed of 30 in/s (76 cm/s)
