MS XX07 Series Integration Guide
Byte
On an addressable boundary, eight adjacent binary digits (0 and 1)
combined in a pattern to represent a specific character or numeric value.
Bits are numbered from the right, 0 through 7, with bit 0 the low-order bit.
One byte in memory can be used to store one ASCII character.
CDRH
Center for Devices and Radiological Health. A federal agency responsible
for regulating laser product safety. This agency specifies various laser
operation classes based on power output during operation.
CDRH Class I
This is the lowest power CDRH laser classification. CDRH Class I devices
are safe under reasonably foreseeable conditions of operation. Software
and other controls to limit exposure to laser light may be required to
achieve CDRH Class I operation. The CDRH time base for Class I
devices is 10,000 seconds.
CDRH Class II
CDRH Class II devices may not emit more than 1 milliwatt average radiant
power. Eye protection for CDRH Class II devices is normally afforded by
aversion responses, including the blink reflex.
Character
A pattern of bars and spaces which either directly represents data or
indicates a control function, such as a number, letter, punctuation mark, or
communications control contained in a message.
Character Set
Those characters available for encodation in a particular bar code
symbology.
Check Digit
A digit used to verify a correct symbol decode. The scanner inserts the
decoded data into an arithmetic formula and checks that the resulting
number matches the encoded check digit. Check digits are required for
UPC but are optional for other symbologies. Using check digits decreases
the chance of substitution errors when a symbol is decoded.
CLSI Editing
An option which inserts a space after the 1st, 5th, and 10th characters of
a 14-character Codabar symbol. Length does not include start and stop
characters.
Codabar
A discrete self-checking code with a character set consisting of digits 0 to
9 and six additional characters: ( - $ : / , +).
Code 128
A high density symbology which allows the controller to encode all 128
ASCII characters without adding extra symbol elements.
