GP Series
- Precision Industrial Balances
 |
|
|
All A&D GP-Series come standard with the RS-232C interface
and WinCT.
(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.
