rs232/rs485 serial data acquisition interface

8, 12-bit ADC, 8 Digital I/O

two PWM or DAC outputs


The ADR2000 serial data acquisition interface allows control of 8 digital I/O lines and 8, 12-bit analog inputs (0 - 5VDC or +/-5VDC), two analog outputs and one event counter via an RS232 or RS485 link. This low-cost serial data acquistion interface is easy to use with Visual Basic, Basic, C, Labview, Testpoint, or other high level languages that allow access to a serial port. The ADR2000 series of data acquisition interfaces are daisy chainable up to ten units. All ADR2000 series boards contain RS232 to RS485 converters.
