The display features an LCD display with a resolution of 2 lines and 40 digits, arranged in a format of 20 columns per line. The digit size is 4.1 x 8.3 dot, enabling clear and easily readable presentation. The display is in white color and is supported by blue backlighting, which enhances readability even in daylight.

The total display area measures 128 x 43 mm.

Applications
This display is primarily intended for use in retail environments, especially in conjunction with the Epson TM-m30 receipt printer. It is suitable for cash register systems in stores, supermarkets, gas stations, or other facilities where clear and rapid information transmission to customers is required. The compact design with dimensions of 130 mm (width) x 100 mm (depth) x 68 mm (height) allows for space-saving installation. The device weighs 270 g and is therefore lightweight and suitable for mobile use.

Functions and Equipment in Detail
The display supports ESC/POS and OPOS emulation, enabling compatible integration into existing cash register systems and point-of-sale software. The interface is via USB 2.0, allowing both data transmission and power supply through a single cable. The power supply output voltage is 5 V, enabling power delivery through the USB connection. The integrated flash memory function allows storage of settings or firmware updates. The display is in black color, which integrates well visually into typical cash register systems. The package includes a stand, which positions the device stably on a surface.

Technology Explained Simply
The LCD technology (Liquid Crystal Display) ensures a clear, energy-efficient display, particularly suitable for indoor use. The blue backlighting improves readability, especially under low ambient lighting conditions. The 2x20 character display (i.e., two lines with 20 characters each) provides sufficient space for short texts such as prices, item descriptions, or transaction notes. The USB 2.0 interface enables fast data transfer and simplifies installation, as no additional power source is required. The OPOS and ESC/POS compatibility ensures broad usability in various cash register systems.

Compatibility and Accessories
The display is specifically designed for use with the Epson TM-m30 receipt printer. It can be flexibly positioned using a USB extension cable, allowing optimal placement at the sales counter. When used with a WLAN-enabled TM-m30 model, the WLAN dongle can be connected behind the display to keep the workspace uncluttered.

Installation and Mounting
Installation is done via the USB port on the receipt printer. The device is placed on a flat surface using the stand included in the package. Power supply is provided through the USB connection, eliminating the need for an additional power source. Configuration is done via the supported emulation protocols (ESC/POS, OPOS), with the exact setup depending on the cash register software used.

Operational Advantages
The display offers reliable and low-maintenance operation with a mean time between failures (MTBF) of 30,000 hours. The combination of compact design, clear display, and simple USB 2.0 integration makes it a practical tool for retail. The use of flash memory enables fast firmware update capability, simplifying maintenance and modernization. The black color design and clear display ensure a professional appearance at the sales counter.
