    Solutions & Applications
    Serial Device Server - Industrial Weighing Solution Traditional weighing scenes rely on manual recording, and at the later stage, use RS232/485 bus mode for data transmission. With the development of industrial automation, a single approach has been unable to continue to meet industrial weighing needs, mainly reflected in:
    Production Line Data Collection Some large manufacturing industries need to collect data on production lines. By using a serial to Ethernet converter, the work efficiency can be greatly improved.
