This FT232RL RS485 USB to DSUB 15PIN male adapter cable is designed as a PLC programming cable for Siemens S7 X27 CP341 interfaces to a PC. The 5 meter length provides flexible deployment for programming, testing, or diagnostics while keeping the PC connected. Key benefits Enables direct PC communication with Siemens S7 CP341 interfaces over RS485, facilitating programming and data exchange. RS485 signaling is bridged to USB through the FT232RL chip for reliable USB to serial communication. DSUB 15 pin male connector ensures compatibility with CP341 interface and similar RS485 PLC connections. Long 5 m cable length supports convenient placement of the PC in relation to the PLC during setup, testing, or maintenance. Simple interface for use in lab environments where a dedicated PLC programming cable is preferred. Key attributes Functionality: USB to RS485 adapter with a DSUB 15 pin male RS485 end for CP341 interface to PC Chipset: FT232RL USB to serial bridge Connectors: USB on the PC side and DB15 (DSUB 15 pin) male RS485 end Cable length: 5 meters Application: PLC programming cable for S7 X27 CP341 interface to PC Compatibility: Intended for Siemens S7 CP341 interface and RS485 devices connected to a PC via USB Technical considerations Built around the FT232RL USB to serial bridge for RS485 communication Uses a DB15 male RS485 interface to connect with CP341 and similar equipment Suitable for use in programming, diagnostics, and data exchange between a PC and RS485enabled PLCs Use cases Siemens S7 CP341 programming: connect the CP341 interface to a PC to load, edit, or monitor PLC programs RS485 device testing: enable a PC to communicate with RS485 devices such as PLCs, HMIs, or sensors for configuration or data collection Field maintenance and diagnostics: provide a flexible, extendable link between a PC and RS485 equipment in production environments Notes For RS485 performance, observe correct wiring polarity and, where applicable, network termination and device addressing Driver installation for the FT232RL may be required on the connected PC depending on the operating system and existing drivers
