Pin Assignments for the PowerLink Cable

The MS7120 scanner interfaces terminate to a 10-pin modular jack. Connect the 10-pin modular plug of the PowerLink cable into the jack then connect the other end of the PowerLink cable to the host. (Refer to page 6 for details). Due to the variations in current supplied by the many available PC’s, Metrologic suggests the use of an external power supply.

MS7120 Series specifications

The Metrologic Instruments MS7120 Series is a powerful line of presentation scanners designed to meet the demanding needs of retail and commercial environments. Known for their ability to read barcodes quickly and accurately, these scanners are ideal for high-volume scanning situations, ensuring that operations run smoothly and efficiently.

One of the main features of the MS7120 Series is its omnidirectional scanning capability. This technology allows the scanner to read barcodes from any angle, significantly reducing the time it takes to scan items and improving the overall customer experience. The MS7120 is equipped with a high-performance laser scan engine, ensuring that it can read both 1D and 2D barcodes with ease. This versatility is particularly valuable in environments where various types of barcodes are in use.

Another significant characteristic of the MS7120 is its compact and ergonomic design. Built to withstand the rigors of daily use in busy retail settings, the scanner features a rugged exterior that can endure drops and spills. Its lightweight design ensures that employees can use it comfortably over long periods, helping to reduce fatigue and improve productivity at checkout counters.

In addition to its hardware features, the MS7120 Series incorporates advanced decoding algorithms that enhance barcode reading performance. This technology allows it to correctly interpret damaged or poorly printed barcodes, mitigating the frustration often associated with challenging scans. Furthermore, the scanner is equipped with an extensive range of interface options, including USB, RS232, and keyboard wedge configurations, making it compatible with most point-of-sale systems.

The MS7120 Series also boasts programmable features, allowing users to customize the settings to fit specific operational needs. This includes the ability to adjust the scan speed, volume of the beep upon a successful scan, and even programming prefixes or suffixes that can be automatically added to scanned data.

With its combination of ruggedness, speed, and advanced scanning technologies, the Metrologic Instruments MS7120 Series is an outstanding choice for retailers seeking a reliable and efficient barcode scanning solution. Its ability to streamline operations and enhance customer service makes it a valuable asset in any retail environment.
