Introduction The Duet™ scanner from PSC®, shown in Figure 1, delivers high performance in a small, fixed scanner which can also be used as a targeted handheld scanner. Its innovative design maximizes productivity, and minimizes operator stress, strain and fatigue. The Duet scanner's compact size uses very little counter space. The product is designed for durability, prolonged life, and low maintenance costs.
Product Overview The Duet scanner is primarily designed for presentation and sweep scanning from a fixed position. The scanner can also be removed from the stand for use as a portable (multi-line) scanner or a single line handheld scanner. Use the Duet scanner's front scan window for presentation and sweep scanning, and the rear scan window for targeted handheld scanning. Figure 2 shows the Duet scanner used as: (1) fixed, (2) portable, and (3) a targeted handheld scanner. Figure 2.
Duet Scanner Features The Duet scanner features include: • A rugged industrialized enclosure which encompasses the entire scanning mechanism. • An adjustable stand that tilts to hold the scanner at the best reading angle. • An LED lamp and speaker provide both visual and audible feedback to the user ( i.e. "good read" of scan, or end of Selftest). • Balanced weight and a shape designed to fit the hand comfortably and reduce fatigue.
Operational Overview The scanner has three operational modes: • Fixed/Portable Mode • Targeted Handheld Mode • Sleep Mode This section describes the three operational modes while the section How to Scan, describes how to use the scanner in the Fixed/Portable and Targeted operational modes. Fixed/Portable Mode In the Fixed Mode, the scanner remains fixed in the stand and reads while a bar code is swept past or presented to the front scan window.
Targeted Handheld Mode Remove the scanner from the stand to use it in the Targeted Handheld Mode. Pressing the trigger switch enables targeted scanning. (See Figure 4). The Targeted Handheld Mode allows the scanner to read bar codes selectively. A Pointer Line provides a visual aid for aiming the single scan line at the bar code. Press the switch once for each bar code scanned. This mode is particularly useful for reading a single bar code where multiple bar codes exist in the same area.
Controls & Indicators The controls, indicators and connectors for the Duet scanner are described in this section. They include: • Trigger switch • Visual Indicator (LED) • Speaker • Interface cable connector Figure 5, below, shows the features, controls, indicators and connectors of the Duet scanner. Figure 5.

Duet Scanner Controls Trigger Switch Pressing the trigger switch causes the scanner to enter the Targeted Handheld Mode. In this mode, the scanner reads bar codes with a single scan line projected from the rear scan window. Releasing the trigger switch returns the scanner to the Fixed/ Portable Scanning Mode. Pressing and releasing the trigger switch will also wake up the scanner, if it has entered Sleep Mode, and return it to normal operation.
Speaker The speaker produces an audible indication of scanner operation. The tones are: • Normal Tone – A single tone when the scanner reads a bar code indicates a good read. • Passed Selftest – A series of four tones are emitted when power is first applied to the scanner. This indicates the scanner passed the Selftest and is operating properly. • Error Tone – The speaker sounds a series of tones alerting the operator of a possible system or component failure.
Sleep Mode Sleep Mode is the term used to describe the scanner’s condition after the motor and/or laser have automatically switched off due to a prolonged period of inactivity. Motion Sensor The scanner includes a motion sensor that detects activity in front of the scan window. Waving your hand or merchandise in front of the window wakes the scanner up when it is in Sleep Mode. In certain low-level lighting conditions, it may be necessary to press the trigger button to wake up the scanner.
Unpacking Before you open the Duet scanner shipping carton, inspect the exterior of the carton for damage. If the carton is torn or crushed, carefully open and inspect the contents to ensure that no damage has occurred to contents. Notify your carrier immediately if you think that there has been any damage to the contents.
Verifying Scanner Operation External Power Supply – If you have a Duet scanner with the optional external power supply, you can verify scanner operation prior to installation to ensure the scanner is fully functional. Follow these procedures to verify scanner operation if you have the optional external power supply. (Reference Figure 7): 1. Plug the scanner end of the interface cable into the rear of the scanner until it clicks into place. 2.
Power-Off-Terminal (P.O.T. Option) – If your scanner uses Power-OffTerminal (P.O.T.), the scanner must be connected to the host terminal to verify the scanner operation. The P.O.T. option requires an interface cable designed to supply power as well as transmit bar code data. To verify the scanner operation with the P.O.T. option follow the steps in the section Power-Up Procedures. Then refer to the previous paragraphs, Passes Selftest or, Fails Selftest, depending on the scanner’s behavior. Figure 7.
Countertop Installation The scanner stand has non-skid rubber feet on the bottom, and is weighted to keep the stand stable. It may be placed on the countertop with no additional installation. The stand may also be permanently mounted to the countertop. Scanner Stand Installation Free Standing – NO additional installation is required when the scanner stand is not attached to the countertop.

Connecting the Scanner The Duet scanner connects to the store host terminal via an interface cable. The cable connects to the scanner with a modular connector and to the host terminal with the connector required by the host (RS-232, OCIA, Keyboard Wedge, Wand or IBM POS). DC power to the scanner is supplied by one of two methods: 1. From the host terminal (Power-Off-Terminal) through a special cable that carries both data and DC power. 2.
AC/DC power supply (if required) 1. 2. Connect the interface cable to the scanner. Connect the DC barrel plug into the side of the connector, or into the DC power connector. 3. Connect the interface cable to the host terminal. 4. Plug the AC/DC power supply into a functional AC outlet. Power up the system and scan a few items to verify that data is properly communicated between the scanner and your POS terminal. Figure 11. Connecting the Scanner to the Host Terminal a.

How To Scan With two scan windows, the Duet scanner can easily adapt to either fixed/portable or targeted handheld scanning applications. The front scan window, with its multiple scan pattern, is used for most retail items. The rear scan window emits a single targeted scan pattern for handheld scanning of hard to read or bulky items, or to read an individual bar code among many bar codes.
To use the scanner in Fixed Mode, place the scanner into the stand. Make sure it is seated securely. In the Fixed Mode, the scanner can read bar codes either in the sweep or presentation mode to accommodate different user styles. Sweep Scanning To perform a sweep scan, move (sweep) the product, with the bar code facing the front window, laterally through the scan volume. As shown in Figure 13, the scan volume for fixed scanning extends approximately 9 inches (23 cm) in front of the scan window. Figure 13.
Figure 14 shows the motion of the item swept past the front scan window. Figure 14. Sweep Scanning a b maxwe ll a. Front Scan Window b.
Presentation Scanning To obtain optimum scanning performance, face the bar code towards the center of the front scanner window. Move the product with the bar code towards the scanner, as shown in Figure 15. Figure 15.
Portable scanning The Duet scanner is also portable. To use as a portable scanner, remove the scanner from the stand but do not press the trigger switch. Present (or sweep) the scanner to the bar code using the front scan window as shown in Figure 16. Figure 16. Portable Scanning a b c a. Front Scan Window b. Bar code c.
Targeted Handheld Scanning Targeted handheld scanning allows the operator to point the scanner instead of lifting heavy or bulky items that are in the customer's hands or shopping cart. A specially designed Pointer Line helps the operator visually aim at the desired bar code. The scanner's shape cradles comfortably in the operator's hand. Its weight is distributed evenly to maximize balance and minimize fatigue. To use the Duet scanner as a targeted handheld scanner: 1.
3. Use the Pointer Line to help locate the center of the bar code before pressing the trigger switch (Figure 18). Small bar code labels need to be close to the scan window, while larger bar code labels should be farther away. Figure 18. Locating the pointer a. Trigger Switch b. Rear Scan Window c. Scan Line User's Guide d. Scan Depth e.
4. Use your thumb to press the trigger switch to scan the bar code as shown in Figure 19. Release the trigger switch when you hear the "good read" tone. Figure 19. Press Trigger switch to Line Scan a b a. Rear Scan Window b. Trigger Switch To continue scanning in the Targeted Handheld Mode, repeat the process above: (3), placing the Pointer Line on the next item’s bar code, and (4), pressing the trigger switch.
Customizing Your Scanner's Operation Customizing or programming a scanner provides maximum flexibility and allows a single scanner to serve many installation environments. Since the Duet scanner supports a variety of interfaces, configurations and bar code symbologies, it may be necessary to customize your scanner to meet the specific requirements of your retail environment. Customizing the scanner is done by scanning special bar codes which change the way the scanner operates.
