rs232/rs485 data acquisition interface

4, 10-bit-ADC , 32 Digital I/O

two PWM outputs


The ADR2100 serial data acquisition interface allows control of 32 digital I/O lines and 4, 10-bit analog inputs (0 - 5VDC ), two PWM outputs and two event counters via an RS232 or RS485 link. The ADR2100 also includes a complete dual stepper motor indexer. 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.
