The FT232RL RS485 USB to DSUB 15PIN male adapter is a dedicated cable for connecting a PC to RS485 devices used in PLC programming and maintenance. Built around the FT232RL USB to serial chipset, this cable provides a straightforward USBtoRS485 interface with a Dsub 15 pin male connector, designed to work with Siemens S7 X27 CP341 interfaces and other RS485 PLC communications. Key benefits Enables PC to RS485 PLC communication: connects a PC directly to RS485 devices and CP341/S7 interfaces for programming, debugging, and data exchange. Reliable USB to serial conversion: uses the FT232RL chipset to deliver stable USB connectivity to RS485 signaling. Flexible operation distance: 3 metre cable length allows convenient placement and setup in workshops or field service environments. Standard RS485 wiring through a DB15 male: DB15 pinout supports typical S7 CP341 and similar RS485 interfaces. Plugandplay potential with driver support: typically recognized as a virtual COM port on compatible systems; driver installation from FTDI may be required. Key attributes Functionality: USB to RS485 adapter with DSUB 15 pin male interface for RS485 networks and PLC programming use. Compatibility: designed for S7 X27 CP341 interface to PC, suitable for Siemens S7 PLC programming and other RS485 connections. Length: 3 metres ( cable length ). Connector: DB15 pin male on the RS485 side; USB connection to PC (type not specified in the title). Chipset: FT232RL USB to serial converter on board. Performance: provides RS485 signaling over a USB interface suitable for PLC programming and RS485 communications. Two to three use cases PLC programming and maintenance: connect a PC to a Siemens S7 CP341 interface via RS485 for programming, parameter adjustments, and file transfers. RS485 device wiring and debugging: interface RS485 sensors, meters, or field devices to a PC for configuration, troubleshooting, and data logging. Industrial data collection and monitoring: link RS485 networks to a PC for realtime monitoring, log recording, or SCADArelated tasks in an S7based environment. Notes Driver requirement: the device is USB based and may require FTDI FT232RL VCP drivers for Windows, Linux, or macOS to create a virtual COM port. Installation and wiring: ensure correct RS485 A/B wiring to the CP341 interface or other RS485 devices, following standard RS485 installation practices. No external power is described; operation relies on USB power through the PC connection. This description reflects the product's stated brand, specifications, model, and features: FT232RL based USB to RS485 adapter with a DB15 male Dsub connector, intended as a PLC programming cable for the S7 X27 CP341 interface to PC, and provided in a 3 metre length.
