Digital– (used in contrast to Analog) describes a coded squarewave signal (processed from an analog signal) which is utilized by decoding circuitry. Digital bar code is generally square wave pulses (0 to 5 volts) with widths which depict the bar and space widths in the code.

DIP– is an acronym for “dual in–line pins,” a type of integrated circuit package. DIP components are used with through–hole or viahole circuit board technology.

Exit Window– is the optical opening through which the laser beam, or other method of illumination, leaves the scanner.

Far Distance– is the farthest distance that a scanner can accurately digitize a given bar code.

Field Width– is the window width. Refers to the greatest width of bar code label that can be successfully interpreted.

Firmware– is a term for software which is permanently designed into a data system device (such as a bar code decoding algorithm) to provide special programs and service routines.

Focal Distance– is the distance of highest resolution in front of the scanner window.

Host Computer– refers to the data system’s controlling processor which interfaces with the decoder and other system elements to receive their data outputs and command their functions.

Interleaved 2 of 5 Check Digit Included– is a decoder option. When enabled with Interleaved 2 of 5 check digit required, the check digit will be confirmed and included in the data message.

Interleaved 2 of 5 Check Digit Required– is a decoder option. When enabled, Interleaved 2 of 5’s checksum will be calculated and confirmed for a valid read.

Laser Enable– is a scanner input signal that controls the flow of power to the scanner. Usually this signal will control all the scanning functions in the scanner.

LED– is an acronym for “light emitting diode.”

Marker Beam– refers to a visual indicator that an infrared laser beam is present. The marker beam is an aid to pointing a hand–held or set up a machine mount scanner. This beam is not necessary for the optical performance of the laser scanner.

Message Length– refers to the number of characters in the data message decoded from a bar code label.
