STEP 1 – CONNECT THE SYSTEM
To connect the system in a Stand Alone configuration, you need the hardware indicated in Figure 1. In this layout
the data is transmitted to the Host on the main serial interface. In Local Echo communication mode, the RS232
auxiliary interface can be used to transmit data independently from the main interface selection. When On-Line
Operating mode is used, the scanner is activated by an External Trigger (photoelectric sensor) when the object
enters its reading zone.

DS4800 OM QUICK GUIDE
The DS4800 OM is completely software controlled and software programmable through Genius™ which allows
adjusting the oscillating frequency and the minimum and maximum oscillation angles of two separate reading
zones.
When the oscillating mirror is programmed to read barcode labels at small angles, position the reader to
at least 15°
for the Skew angle. This angle refers to the most inclined or external laser line, so that all other laser
lines assure more than 15° Skew. This avoids the direct reflection of the laser light emitted by the reader.

STEP 3 – FOCUS THE SCANNER
The reading distance depends on the focus distance of the scanner and should be set according to the
application requirements. The Focus Position is set directly through the focus adjustment screw on the front panel
of the scanner. This screw moves the internal lens of the scanner to change the focal length of the scanner. The
setting is continuous but should not be set beyond the limits "Too Far" or "Too Near" which appear on the display
at the extremes of the focus range. Although the scanner reads across the entire focus range, there are three
guaranteed positions which correspond to the reading diagrams in the Appendix of this Quick Reference Guide.
1. Power up the scanner and wait for the power up
sequence to finish. By default the scanner focus is in
the Unlocked position. The alternating message on the
display shows the mechanical Focus Position.
2. Using a screwdriver turn the focus adjustment screw in
the desired direction clockwise (focus nearer to the
scanner) or counterclockwise (focus farther from the
scanner). The focus position in centimeters and inches
is shown on the scanner display.
The value of the Focus Position must be
stored in memory. If the mechanical position
changes by more than the allowed tolerance
NOTE
of the value in memory, an alarm will be sent.
See the Focus Lock function in step 4,
X-PRESS™ Configuration.
As an additional visual aid during focusing, the indicator LEDs show the relative focus position as follows:

STEP 4 – X-PRESS™ CONFIGURATION
X-PRESS™ is the intuitive Human Machine Interface designed to improve ease of installation and maintenance.
Status and diagnostic information are clearly presented on the display (which can be configured in various
languages) and by means of the five colored LEDs, whereas the single push button gives immediate access to
the following relevant functions:
AutoSetup to self-optimize and auto-configure reading
performance in demanding applications
AutoLearn to self-detect and auto-configure for reading
unknown barcodes (by type and length)
Focus Lock to memorize the mechanical focus position
Test Mode with bar-graph visualization to check static readin
performance
The colors and meaning of the five LEDs are illustrated in the following table:
READY (green) This LED indicates the device is ready to operate.
GOOD (green) This LED confirms successful reading.
TRIGGER (yellow) This LED indicates the status of the reading phase.
COM (yellow) This LED indicates active communication on main serial port.
STATUS (red) This LED indicates a NO READ result.
During the reader startup (reset or restart phase), all the LEDs blink for one second.
On the back of the reader near the cable, the “POWER ON” LED indicates the laser scanner is correctly powered.
When entering the X-PRESS™ interface on the DS4800 Oscillating Mirror remains in the default
fixed position (0°) in order to make barcode reading easier while performing the X-PRESS™
functions.

Once entered, the reader starts a procedure to automatically detect and recognize barcodes (by type and
