1 Introduction
This advanced scanner is a proud to be among the world's first dual-laser presentation scanners, and it incorporates numerous record-breaking features. Its
pioneering application of dual laser diodes drastically enhances scanning
power by doubling the scan lines, broadening scan angle and intensifying the
scan pattern across the scan field. With this state-of-the-art technology, it is
able to deliver a comprehensive 32-line scan pattern cycling at 2400 scans per
second. The scanner is additionally equipped with Z-SCAN technology—an
innovative ASIC hardware decode protocol that provides real-time decoding
that effectively shortens customer transaction time.
The broad, omnidirectional scan field effectively facilitates hands-free scanning
of barcodes on products of many different shapes. Also, the scanner is programmed with multiple beeper tones and barcode data edition functions to
accommodate a variety of applications.

4 Connecting and Mounting
4.1 Power
The scanner requires a minimum of 300mA at 5 Vdc power. The interface cable
that comes with the scanner supports both direct power (where the scanner
takes power from the host machine) and external power (that's what the supplied power adapter is for). A sufficiently robust POS system can support a
scanner successfully without external power; a POS system with a barely adequate power supply may produce erratic performance (either of the POS system itself, or of the scanner, or both) when a scanner is attached. Unless you
are sure your POS system can handle the load, it is recommended that you use
the supplied power adapter. When an external adapter is connected, the scanner does not take power from the host.
The scanner turns on when power is supplied, and turns off when power is
removed. There is no on/off switch on the scanner itself.
Use only an AC/DC power adapter approved for the scanner. Use of other
power supplies may cause damage to the product, and void the factory warranty.
4.2 Verifying Scanner Operation
Before mounting your scanner, please follow the procedure below to verify
scanning operation.
1. Take out the screws and remove the mounting plate.
Figure 2: Remove Mounting Plate
2. Insert the 8-pin modular plug of the power link cable into the “host” connector in the back of the scanner until a firm click is heard.
3. Plug the power adapter into the jack on the power link cable. (See Figure
4. Plug the AC end of the power adapter into an AC outlet. The scanner powers up, the buzzer sounds four beeps and the LED indicator glows blue.
5. Present a known-good test barcode to the scanner. The scanner should
issue a short beep and the LED should flash red momentarily. [If the scanner is connected to a keyboard wedge for this test, it should read one barcode, beep, then remain with a red LED indicating light. This is normal
when the keyboard wedge is not connected to a live host terminal.]
Note: If the scanner does not produce any beeps, or produces the wrong
beeps, or the LED does not light, remove the power connection and refer to the
section on Troubleshooting.
4.3 Mounting
After the scanner passes its verification test (Section 4.2 above), proceed with
The scanner should be installed in a location away from direct sunlight; high
levels of ambient light reduce scanner effectiveness.
The two basic styles of mounting are a) with the included mounting plate, and
b) with a custom bracket (not included) for back mounting. If an auxiliary handheld scanner is to be attached, it must be properly connected as part of the
mounting process.
Mounting Plate Installation
1. Position the mounting plate in the desired location and secure it in place. If
desired, use the full-size boring template in Figure 6 on page 21.
2. Insert the connecting cable in the slot in the mounting plate.
3. Insert the 8-pin modular plug of the power link cable into the “host” connector in the back of the scanner until a firm click is heard.
4. Move the scanner into position on the mounting plate, engaging the tab on
the underside. Be careful not to pinch the cable.
Figure 3: Install Scanner on Mounting Plate
5. Replace the mounting plate screws.
Auxiliary Handheld Scanner Connection (optional)
The scanner supports the operation of an auxiliary handheld scanner, which
may be connected via a 10-pin RS-232 modular plug to the connector marked
“aux” in the back of the scanner.
1. Insert the connecting cable in the slot in the mounting plate, but reverse the
cable relief molding of the scanner interface cable in the mounting plate to
allow space for the auxiliary handheld scanner cable.
2. Insert the 8-pin modular plug of the power link cable into the “host” connector in the back of the scanner until a firm click is heard.
3. Insert the auxiliary cable connector into the 10-pin “aux” jack until it clicks
and route the cable through the space above the scanner interface cable.
4. Move the scanner into position on the mounting plate, engaging the tab on
the underside. Be careful not to pinch any cables.
5. Replace the mounting plate screws.
Back Mounting
If desired the scanner may be mounted to your own custom bracket using the
threaded mounting holes on the back. (See Figure 1.) The mounting holes are
threaded to accommodate M4 x 0.7 machine screws to a depth of 5.0 mm.
Make sure your bracket design allows for the exit of the interface cable. The
supplied mounting plate protects the interface cable connection, but requires
that the cable exits from the back of the unit.
4.4 Connecting to the Host
The power link interface cable comes with different host-end connectors,
depending on the host. Follow the steps below to connect the interface cable to
the host.
1. Make sure that the power of the host system is off.
2. Connect the host end of the interface cable to the appropriate connector on
the host system.
3. For those cases where external power is used, plug the external AC power
adapter into the jack on the interface cable. (See Figure 1.)
4. Turn on the host system.
5 Setting Up the Scanner
In some cases no setup is required. The scanner is either pre programmed to
suit the situation, or it auto detects and is ready to go. In other cases the scanner must be informed about what kind of system it is connected to. This can be
done in a few moments using the included booklet titled Programming Guide.
The Programming Guide may be used to set a number of parameters on the
scanner: communication interface type (RS-232, Keyboard, USB), beep tone,
sleep mode timings, same-code delay time, enable/disable decoding of numerous code types, and more advanced things like set headers and trailers.
Individual parameters may be set at any time without affecting the other parameters.
5.1 Scan Test
1. With the scanner running (LED blue) and the host system on, try to scan
several known-good barcodes.
2. Check the results on the POS screen. If the scanner is reading okay, no further setup may be necessary.
3. If the POS screen does not show the expected scans, go to Set Up, below.
5.2 Set Up
1. With the scanner running (LED blue) and the host system on, present the
<Enter/Exit Programming Mode> barcode, found on the inside cover of the
Programming Guide, to the scanner. The scanner gives two beeps: low and
high, and the LED turns red. The scanner is in programming mode.
2. Decide which parameters are required and find their barcodes in the Programming Guide.
3. Cover unwanted codes with your hand and present the desired codes, one
by one, to the scanner. The scanner beeps once as it accepts each code.
4. When done, again present the <Enter/Exit Programming Mode> barcode.
The scanner beeps twice, once long and once short, and the LED returns
to blue. The scanner has been programmed.
5. Test again with known-good barcodes. If results are good, you are done
setting up. Otherwise, return to step 1 and try again.
6 Operation
The scanner can read barcodes in either sweep or presentation mode to
accommodate different requirements. Sweep mode means moving items
through the scan volume. Left to right, right to left, top to bottom, bottom to top,
etc. are all okay. This scanner is truly omni directional. Sweep scanning is usually used for high throughput and reduced product handling. Presentation scanning is used where counter top space is at a premium. The product is moved
toward the scan window (“presented”) until the barcode is read, then the product is removed.
6.1 LED Indications
A dual color red-blue LED indicates operating status as follows:
LED status
No power supplied to the scanner.
Steady blue light
The scanner is on and ready to scan.
One red flash
A barcode has been successfully decoded.

check the power supply.
6.2 Beeps
A beeper gives audible feedback on scanner operation.
One beep
A barcode has been successfully decoded.
Four beeps in series
This indicates the scanner passed the power
on self-test and is operating properly.
Two beeps: low-high
The scanner has entered programming
Two beeps: same tone
Scanner has returned from programming to
normal mode.
Continuous tone
This is a failure indication. Return the unit for
6.3 Changing the Beep Volume
The scanner can be programmed with the Programming Guide to change
beeper tone, volume and duration; the beeper volume can also be changed by
using the push button.
The default beep volume is loud. There are three sound levels: loud, medium,
and low.
Press and hold the push button for about 5 seconds. The scanner will cycle to
its next level. Repeat till the desired level is reached.
Note: The volume setting is saved in volatile memory. That means the change
will lost when the scanner powers down. On next power up the scanner resets
to the configured setting. If you wish to keep the changed the volume setting,
use the Programming Guide to set the changes.
6.4 Sleep Mode
After the scanner has been inactive for a period of time, the laser automatically
turns off; after some more time, the motor turns off and the scanner enters
“sleep mode,” indicated by the blue status LED blinking once a second. To
wake up the unit, simply present an object close to the scanner window, or
press the push button.
Note: The scanner includes a motion sensor that detects activity in front of the
scan window. The detecting distance is up to about 50mm (2 inches) from the
scan window, depending on ambient light.
6.5 Controlling the Scanner from a POS System
The scanner can be controlled from the POS system via the RS-232C interface.
Control can be accomplished by transmitting the following single-byte commands to the scanner. The default settings for the commands are as follows:
Byte is Also
OE Hex
enable (resumes from disable)
Shift Out or <Ctrl-N>
OF Hex
Shift In or <Ctrl-O>
05 Hex

ENQ or <Ctrl-E>
12 Hex
DC2 <Ctrl-R>
14 Hex
wake up (resumes sleep)
DC4 <Ctrl-T>
Note: When the scanner is disabled, the scanner motor will continue running
until the scanner goes into sleep mode.
7 Maintaining the Scanner
The scanner is designed for long-term trouble-free operation and rarely needs
any maintenance. Only an occasional cleaning of the scanner window is necessary in order to remove dirt and fingerprints.
7.1 Cleaning the Scan Window
Wipe the scan window with a soft lint-free cloth and a non-abrasive cleaner to
avoid scratching. The scan window may be cleaned while the scanner is running.
7.2 Replacing the Interface Cable
The standard interface cable is attached to the scanner with an 8-pin modular
connector. When properly seated, the connector is secured in the scanner handle by a flexible retention tab. The cable is designed to be field replaceable.
Replacement cables can be obtained from your authorized distributor.
To replace the cable, follow these steps.
1. Make sure that the power of your computer system is switched off, and if a
power adapter is used, disconnect it from the scanner cable.
2. Disconnect the old scanner cable from the computer system.
3. Remove the screws that hold the mounting plate on the scanner and disengage the mounting plate.
4. Press down the small tab on the connector where the old cable is attached
to the scanner and pull. The connector should come out.
5. Insert the connecting cable in the slot in the mounting plate.
6. Insert the 8-pin modular plug of the power link cable into the “host” connector in the back of the scanner until it clicks.
7. Mate the scanner and the mounting plate, engaging the tab on the underside. Be careful not to pinch the cable.
8. Replace the mounting plate screws.
9. Plug the new cable into the host.
10. If a power adapter is used, plug the power adapter into the jack on the interface cable.
