DS4800 QUICK GUIDE
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.

STEP 2 – MOUNT AND POSITION THE SCANNER
1.To mount the DS4800, use the mounting bracket to obtain the most suitable position for the reader as shown in the figures below.

Pitch
-45° -15° 0° 15° 45°
Figure 3 - Positioning with Mounting Bracket
2.When mounting the DS4800 take into consideration these three ideal label position angles: Skew 15° to 30°, Tilt 0° and Pitch 0°.

3.Refer to the Reading Diagrams in the Appendix of this Quick Reference Guide to decide the distance your scanner should be positioned at.

DS4800 QUICK GUIDE
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. 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 can be stored in memory. If the mechanical position changes with respect to the value in memory, an alarm will be sent. See the Focus
Lock function in step 4, X-PRESS™ Configuration.
NOTE
As an additional visual aid during focusing, the indicator LEDs show the relative focus position as follows:
