The USB to RS232 Converter Cable with 4 Pin Open Wire Ferrules connects a USB equipped computer to industrial equipment with an RS232 serial interface. It supports configuration, monitoring, data exchange, testing, and maintenance for compatible PLCs, sensors, actuators, controllers, and data acquisition units.
The cable combines an FT232R based USB to serial interface with four conductors terminated in European style ferrules. These prepared wire ends fit compatible screw clamp terminals, making the cable useful when equipment exposes its serial connections through a terminal block rather than a dedicated plug.

How Does the FT232R USB to RS232 Cable Work ?
The cable connects the computer and industrial device in three stages:
- USB connection: Plug the cable into a computer or industrial PC.
- Serial interface: The FT232R chip manages communication between the USB host and the cable's serial interface.
- Terminal wiring: Secure the four ferrule-terminated conductors to the corresponding RS232 terminals, following the equipment wiring diagram.
When the wiring and communication settings match, compatible computer software can exchange serial data with the device. The cable provides the physical link; command processing and control functions remain with the software and connected equipment.

Typical Industrial Applications
The USB to RS232 Converter Cable supports serial communication during setup, data exchange, and service work.
- PLCs and automation controllers: Programming, parameter setup, monitoring, and troubleshooting.
- Sensors and actuators: Communication with devices that provide an RS232 terminal interface.
- Data acquisition units: Retrieving measurement data and configuring acquisition equipment.
- Control panels and machinery: Equipment integration, commissioning, testing, and maintenance.
