TEKLEAD T-E2 / TEK-E2-3189 2D Embedded Barcode Scanner | NEOTECH® UAE

Compact Fixed-Mount 1D/2D CMOS Scan Module with Automatic Induction, USB and RS-232 Connectivity for Kiosks, POS and Embedded Systems The TEKLEAD T-E2 / TEK-E2-3189 is a compact fixed-mount 2D barcode scanning module designed for integration into kiosks, POS equipment, access-control terminals, vending machines, self-service systems and other embedded applications. The 2D version uses a planar CMOS imaging sensor to decode common 1D and 2D barcodes, including QR Code, Data Matrix and PDF417. It supports manual trigger, automatic induction and continuous scanning modes, allowing the scanner to operate inside unattended or hands-free equipment without requiring a conventional handheld scanner. USB and RS-232 interface options make the T-E2 suitable for both modern computer-based installations and equipment that still relies on serial communication. Important Model Identification TEKLEAD's principal product information currently identifies this embedded scanner platform as: T-E2 2D Embedded Automatic Induction Wired USB / COM / RS-232 Barcode Scanner The reference TEK-E2-3189 is also associated with documentation for the T-E2/E2 scanning engine. Because TEKLEAD offers both 1D CCD and 2D CMOS variants, NEOTECH® recommends verifying the exact 2D configuration before ordering. This page focuses specifically on the 2D CMOS version.

Supported 2D Barcodes The 2D CMOS version supports major two-dimensional barcode formats including: QR Code Data Matrix PDF417 This makes the scanner useful for applications involving mobile tickets, QR-based identification, self-service transactions and other 2D-code workflows. Automatic Induction Scanning One of the key functions of the T-E2 is automatic induction scanning. Instead of requiring the user to press a handheld scanner trigger, the module can detect a presented barcode and initiate scanning automatically when configured for sensing operation. This can be useful for: Self-service kiosks Access-control terminals Ticket-validation equipment Vending machines Check-in terminals Automated counters Embedded POS equipment Actual triggering behaviour can be configured according to the scanner's supported operating modes. Continuous Scanning The scanner also supports continuous scanning. In this mode, the scanning engine remains ready to decode compatible barcodes without requiring an individual trigger operation for every scan. Continuous mode may be useful in embedded systems where barcodes are repeatedly presented to a fixed scanning window. The appropriate scanning mode should be selected according to the application to avoid unintended duplicate or nearby barcode reads. Manual Trigger Mode Manual triggering is also supported. This provides flexibility when the scanner is integrated into equipment where the host system or operator needs to control exactly when scanning begins. The best trigger mode depends on the kiosk, POS application or embedded controller. USB Connectivity USB provides a practical interface for integration with compatible: PCs POS computers Industrial computers Kiosks Embedded controllers Self-service terminals Depending on the selected configuration, USB operation can be configured for the required host environment. Software and interface mode should be verified before deployment. RS-232 / COM Connectivity The T-E2 is also available with RS-232 serial connectivity. RS-232 remains useful in commercial and industrial equipment where serial communication is required, including: Kiosks Access-control systems Embedded controllers Legacy POS systems Vending machines Industrial equipment RS-232 configurations may require separate power depending on the cable and system architecture. Customers should verify connector type, pinout, baud-rate settings and power requirements before integration. Screen Barcode Reading The 2D CMOS scanning engine can be used for compatible barcodes displayed on electronic screens. Potential applications include reading QR or other supported codes from: Smartphones Tablets Digital tickets Electronic membership cards Mobile payment applications Electronic access passes Successful screen scanning depends on factors such as screen brightness, barcode size, contrast, viewing angle, reflections and display technology. Barcode Resolution TEKLEAD's published T-E2 specification identifies example decoding capabilities including approximately: Code 39: 5 mil QR Code: 8.7 mil under specified test conditions. Barcode readability depends on print quality, contrast, barcode dimensions, distance, angle and environmental conditions. These figures should therefore be treated as manufacturer test specifications rather than guaranteed performance for every barcode. Scanning Distance The manufacturer publishes different working distances depending on barcode type and density. Examples include approximately: 5 mil Code 39: 5–12 cm 15 mil Code 39: 4–25 cm 10 mil Code 93: 4–21 cm 15 mil UPC/EAN: 4–25 cm 20 mil QR Code: 4–25 cm These values illustrate why the required barcode should be tested during kiosk or equipment design. There is no single fixed reading distance that applies to every barcode. Compact Embedded Design The T-E2 is designed as an embedded scanning module rather than a conventional handheld scanner. This allows it to be incorporated into equipment where: Space is limited The scanner needs to remain fixed Hands-free scanning is required The scanner should be concealed within an enclosure The user presents a barcode to a fixed window The final enclosure must provide an appropriate unobstructed scanning window and mounting position. Kiosk Applications The TEKLEAD T-E2 can be considered for: Self-service kiosks Visitor registration Hotel check-in systems Queue-management kiosks Ticketing machines Information terminals Payment kiosks Membership systems The scanner itself only captures and decodes barcode data. The complete kiosk application, user interface and transaction logic are provided by the host system. Access-Control Applications Potential access-control applications include: QR visitor passes Electronic entry tickets Membership identification Event admission Temporary access codes Building check-in Before deployment, customers should confirm that the scanner supports the exact barcode format generated by their access-control software. The scanner does not independently make access decisions; it supplies decoded barcode data to the connected system. Vending and Self-Service Equipment The compact fixed-mount format can also be integrated into: Vending machines Locker systems Collection terminals Self-service payment equipment Parcel terminals Automated dispensing systems Mechanical integration, electrical interface and software communication should be validated by the equipment designer or system integrator. Retail and POS Applications The T-E2 may also be used where a fixed scanner is preferred over a handheld device. Potential applications include: Embedded POS counters Price-check terminals Loyalty applications Customer self-check functions Coupon scanning QR-based promotions For conventional high-volume checkout environments, customers should compare the T-E2 with purpose-built presentation scanners before deciding. Installation Considerations Because the T-E2 is an embedded module, successful installation depends on more than the scanner specification alone. The equipment designer should consider: Mounting position Scan-window dimensions Barcode presentation angle Reading distance Ambient lighting Reflections Host interface Cable routing Power supply Ventilation Software communication Maintenance access Testing with the actual barcode and final enclosure is strongly recommended before quantity deployment. Purpose of Use The TEKLEAD T-E2 / TEK-E2-3189 is designed primarily for embedded automatic barcode scanning. Its main advantage is the combination of: 2D CMOS Imaging + Automatic Induction + USB / RS-232 + Compact Fixed-Mount Design This makes it more appropriate for integration into equipment than a conventional handheld barcode scanner. Compatibility Before ordering, verify compatibility with: Host operating system POS software Kiosk application Access-control software Embedded controller USB interface requirement RS-232 interface requirement Serial communication parameters Required barcode symbologies Barcode size and density Screen-reading requirement Power supply Mechanical enclosure NEOTECH® recommends testing the exact scanner configuration with the intended host system before large-scale deployment.
