The Allen-Bradley 1747-PIC Personal Computer Interface Converter is a legacy RS-232 to DH-485 interface that links a PC’s serial port to an SLC 500 DH-485 network for programming and data exchange. As an interface/converter, it translates RS-232 signals from the computer into the DH-485 data link used by SLC 500 processors and related devices, enabling PC-based communication with the SLC-500 family. Used with traditional RS-232 PCs and Rockwell software tools for SLC-500 communication, the 1747-PIC provides a dedicated PC-to-DH-485 bridge within the SLC 500 ecosystem.
