Allen-Bradley 8520-D15M Processor Video Connector is the CN19M 15-pin D-shell video interface on the 8520 9/Series CNC processor board (notably the 9/230 processor board), used to carry the processor's video signal to the removable front-panel interface module. The connector is a male 15-pin D-shell (CN19M) mounted on the processor board, forming the dedicated video path within the CNC control system's operator interface. In Rockwell Automation documentation for the 8520 9/Series, CN19M is identified as the video connector that links the processor to the front-panel/video display subsystem.
