1.3 INDICATORS
The DS6500 decoder base provides an LCD display for system messages and configuration
menus. The three keys present on the side of the display allow configuration menu
navigation (Figure 3, 1).
The three LED indicators have the following functions:
POWER ON
(red) Indicates the reader is turned on (Figure 3, 4)
PHASE ON
(yellow) Indicates the presence sensor is turned on (Figure 3, 3).
TX DATA
(green) Indicates the main serial interface is operating correctly during
data transmission (Figure 3, 2).
1.4 OSCILLATING MIRROR MODELS
Oscillating mirror models are used when coverage of a large reading area is required, mainly
in picket fence applications.
The DS6500 scanner mounts a dedicated optic head with integrated oscillating mirror driven
by a linear motor. The speed, the precision, the repeatability, and the reliability of this driving
technology assure high level performance.
The new oscillating mirror is completely software controlled and software programmable. The
Genius™ software tool allows adjusting the linear motor speed (oscillating frequency) and
the upper and lower limits of the oscillation by defining the top and bottom line limit angles.
When the oscillating mirror is programmed to read barcode labels at very small angles,
position the reader to
assure at least 10°
for the Skew angle (see par. 2.4). This angle refers
to the most inclined or external laser line, so that all other laser lines assure more than 10°
Skew. This avoids the direct reflection of the laser light emitted by the reader.
