Worth Data 7000 manual Laser Options, Aiming the Laser Dot

To scan a bar code using your laser scanner, (whether it be a handheld or integrated)

•put your RF Terminal in One-Way mode with the host computer program not running; or even unplug the serial cable,

•point the laser scanner at the bar code at about 6” away.

•Pull the trigger (or push the button on an integrated model) and line up the beam on the bar code. If you don’t get a read, vary the distance of the scanner from the bar code by pulling up or moving down. The idea is to scan through the center of the bar code.

Laser Options

Several options are applicable to all laser scanners that are used with the RF Terminal. These options are: 1) Longer timeout on the laser reading, and 2) Double decode required.

Longer Laser Reading: A temporary solution to problem bar codes is sometimes to increase the length of the time the scanner attempts to read, from the default 2-second beam to a 4-second beam.

Double Decode: The default setting for the RF Terminal is one successful decode results in a “good read”. If you are getting incorrect reads, (due to defective bar codes), a temporary solution is to turn on make the RF Terminal perform two straight identical decodes before beeping, outputting data, and completing a “good read” read.

There are two Setup Options that do not apply to the LZ300. The two options are:

•“Aiming Laser Dot” for a predetermined time before the laser beam expands into a “line” for reading.

•“Difficult Code 39 Reading” for reading Vehicle Identification Numbers (VIN) through the automobile windshield. This applies only to the external tethered LZ400 Laser Scanner.

Aiming the Laser Dot:

Sometimes it is difficult to see the laser beam and know you are on the bar code, especially if you are attempting to read outdoors in direct sunlight. The laser can be outputted as a brighter dot for a few seconds, allowing the user to place the dot in the middle of the bar code; then the laser beam starts sweeping for the read. As shipped, the laser beam never forms an aiming dot, but you can program a number of seconds that you wish the aiming dot to appear before the sweeping beam by scanning the following:

"Difficult Code 39 Reading":

This setting facilitates reading of difficult Code 39 bar codes such as the Vehicle Identification Number (VIN number) on automobiles, especially reading through a windshield. VIN numbers are long, often weathered, often dirty, and challenging to read.

To enable the more aggressive Code 39 algorithms necessary to read windshield VINs change the Decode Option to 1 or 2 in the Code 39 Options menu.

A clean windshield also makes reading bar codes easier.
