Frequently Asked Questions

What are the power requirements for the GM73 scanner?

The GM73 operates at 5V DC with a typical current draw of 180mA. It is designed for direct integration with standard 5V logic systems, including those powered by USB ports or regulated microcontroller power rails.

How do I communicate with the scanner using the UART interface?

The UART interface operates at TTL voltage levels (3.3V/5V compatible). You can send simple serial commands to control scanning modes (trigger, continuous) and receive decoded barcode data as ASCII strings. The default baud rate is typically 9600 bps but is configurable.

What is the minimum bar width (resolution) this scanner can read?

The GM73 can reliably decode barcodes with a minimum bar width (or module size for 2D codes) of 6 mil (0.1524mm). This high-resolution capability allows it to read dense barcodes commonly used in electronics and pharmaceutical packaging.

Can this scanner read codes printed on curved or reflective surfaces?

Yes, the CMOS image sensor and advanced decoding algorithms are optimized to handle challenging surfaces, including mild curves, reflective labels, and low-contrast prints. The 30-150mm working distance provides flexibility for different surface geometries.
