1) “Aiming Laser Dot” for a predetermined time before the
laser beam expands into a “line” for reading. The RF
Terminal requires a no charge feature to be added to it
before shipping for the Aiming Dot to be used.
2) “Difficult Code 39 Reading” for reading Vehicle
Identification Numbers (VIN) through the automobile
windshield
Aiming Laser Dot:
(Requires Special Modification on the RF Terminal at Factory)
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:
From the Keypad, go to RF Terminal Setup. Choose “Other”. Press Enter
repeatedly until you get to the parameter labeled “AIMING DOT”. The
default is 00. Enter the time in 1/10s of a second you wish the dot to appear
before the laser beam spreads, (i.e. enter 30 for 3 seconds). Remember, this
feature is only supported with RFx9082A and higher, the LZ200D scanner,
and an RF terminal with factory modifications to support it.
"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 with a LZ200 or with the RF Terminal’s integrated laser:
Scan Start Setup
Scan 2 of 5 Code
Scan D for windshield reading
Scan End Setup
To return to the default Code 39 decode algorithms, scan B instead of D.
Don’ forget the common sense things you can do to facilitate reading the
VIN:
1) Be sure the window on the laser scanner is clean.
2) Be sure the windshield itself is wiped clean before reading
