RS-232 interface standard on all GP-Series

All A&D GP-Series come standard with the RS-232C interface and WinCT.

balance communication software (Windows Communication Tool Software), provides easy transmission of weighing data from the A&D balance to a computer using the RS-232c interface.  Quickly export data into Windows applications in a manageable format limited only by the computer's capabilities.  Read more about WinCT here

Using a USB/RS-232C Converter, you can transfer data between a USB equipped PC and multiple GP balances. This also makes your GP balance hot-swappable with no need to turn the balance and computer (requires Win 98 or higher) off before disconnecting the balance.
