GRAM S3 is equipped with a standard RS-232C serial interface, allowing direct and reliable connection to PCs and external peripherals. This enables secure background transmission of weighing data via COM port for documentation, data logging and basic system integration.

For simple PC connectivity without additional software, GRAM S3 supports the U.Key USB direct cable as an option. This plug-and-play solution functions as a keyboard emulator, sending the numeric weighing value directly into any active software field, such as spreadsheets or inventory systems.

An optional Bluetooth interface is also available, enabling wireless data transmission to a PC. Like the U.Key cable, the Bluetooth connection operates as a keyboard emulator, providing fast and cable-free data entry.

GRAM S3 is compatible with PW-Link PC software, which enables structured recording of weighing results including weight, unit, date and time. Weighing reports can be exported in CSV or PDF format and customised with company information, supporting traceability and quality documentation in laboratory and industrial environments.
