DS4800 OM 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 OM, use the mounting bracket to obtain the most suitable position for the reader as

shown in the figures below.

Figure 3 - Positioning with Mounting Bracket

2. When mounting the DS4800 OM take into consideration these three ideal label position angles: Skew 15° to 30°,

Tilt 0° and Pitch 0°. The Skew angle refers to the most inclined or external raster line, so that all other raster

lines assure more than 15° Skew.

Assure at least 15° Minimize Minimize

Figure 4 –Skew, Tilt and Pitch Angles

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 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 assure

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.

Figure 6 - Oscillating Mirror Reading Position

In the above case, the zone where the scan line is perpendicular to the reflecting surface corresponds to a neutral

zone at the center of the reading field.

NOTE

By limiting the raster width to the minimum necessary, the number of scans on the reading

surface is increased.

DS4800 OM 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. 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.

NOTE

The value of the Focus Position must be

stored in memory. If the mechanical position

changes by more than the allowed tolerance

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.

NOTE

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.

AUTO LEARN

If you are configuring your scanner using X-PRESS™, you must start with the Auto Learn procedure.

1. Enter the

Auto Learn function by holding the X-PRESS™ push button pressed until the LEARN LED is on.

2. Release the button to enter the Auto Learn function.

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

length), which are presented to it (*). The laser turns on and the LEARN LED blinks to indicate the ongoing

process.

The procedure is as follows:

A) place the desired barcode on the scanline.

B) wait until the LEARN LED stays steady on

(indicating the reader has detected the barcode).

C) repeat, if needed, the above two steps to

program up to 10 different barcodes (the LEARN

LED returns to the blinking state for the next

code). If more than one barcode is detected in

the scan line, the Multi Label mode is enabled

(refer to the “2K/4K Family Software

Configuration Parameter Guide” Help file).

3. Exit the process by pressing the X-PRESS™ push button once. The scanner will restart at the end of the

process, and then the detected barcodes are automatically configured in scanner memory.

DS4800 OM QUICK GUIDE

NOTE

If the barcode cannot be read because of low contrast or excessive ambient light, you can

perform the AutoSetup function to optimize the optical parameters. Then you can perform

AutoLearn to recognize the barcode symbology.

* In case of Programming Barcodes, refer to the “ID-NET™ Programming Barcodes And Setup Procedure” document in the

product CD.

AUTO SETUP (OPTIONAL)

At the end of the Auto Learn procedure, you can perform the Auto Setup procedure to set up the reading

parameters.

1. Enter the

Auto Setup function by holding the X-PRESS™ push button pressed until the SETUP LED is on.

2. Release the button to enter the Auto Setup function.

Once entered, if a barcode label is positioned in front of the scanline, the scanner automatically performs the

optimal setup of the reading parameters for that specific barcode.

B) enter the AutoSetup function (the laser turns on

and the SETUP LED blinks to indicate the

ongoing process)

C) wait until the SETUP LED stays steady on

(indicating the reader has detected the

barcode)

This procedure ends either when the barcode is successfully decoded or after a timeout of about 7 (seven) seconds.

The scanner will restart at the end of the process, and then the optimized reading parameters for that barcode are

automatically configured in scanner memory.

FOCUS LOCK/UNLOCK

You must perform the Focus Lock procedure to save the mechanical focus position to memory. If the mechanical

focus position is changed by more than the allowed tolerance of the value in memory, a diagnostic alarm will be

sent to the display.

1. Enter the Focus Lock function by holding the X-PRESS™ push button pressed until the FOCUS LOCK LED is on.

2. Release the button to enter the Focus Lock function.

Once entered, the scanner automatically performs the Lock (saving) or Unlock procedure depending on the

previous state of the Locked Position parameter.
