ADR7700 RS232 / RS485 Serial Data
Acquisition Interface ( 16-bit )
ADR7700 RS232/RS485 Serial Data Acquisition Interface (
Dimensions, 4.0" X 2.8" )
The ADR7700 is an high resolution/accuracy, build-to-order data
acquisition interface designed primarily for OEMs. Each unit is scaled and calibrated to
customer specified input ranges. This low-cost build-to-order serial data acquisition
interface is easy to use with Visual Basic, Basic, C, Visual
C++, Labview, Testpoint, or other high level languages that allow access to a serial
port.
