Works with CX-Programmer for online edits and ladder monitoring. ## Mounting & Wiring Notes Slides into any vacant slot in a CS1 rack — no tools, no drivers. Serial pinout matches the standard Omron DTE configuration; set port parameters in the CPU's I/O table (baud, parity, stop bits). Bond the shield at the PLC end only to keep ground loops off the backplane.","metaTitle":"Omron CS1W-SCB21-V1 Comm Card, 2-Port RS-232C","metaDescription":"CS1W-SCB21-V1 communications option card for CS1 PLC, two RS-232C ports.
