Serial Communication with an ADC board

The ACC4-ADC, a serial adapter with an ADC option, enables the user to use any member of the Mx4 controller family outside of the computer rack as a stand-alone unit or as a serially programmable unit inside the computer. Either RS-232 or RS-485 with multi-drop capabilities can be used. The Acc4 works with Mx4 PC/AT, VME and Multibus platforms.

The ACC4-ADC adds analog to digital converter (ADC) input channels to the Mx4 controller. The ADC inputs have an input voltage range of +/- 10 volts. The analog inputs may be used in DSPL programming and/or read from the Mx4 Dual Port RAM by the host.
