## Long description

Renkforce RF-4951528 is a compact USB 2.0 Type A to screw terminal serial adapter that provides a direct point-to-point connection between a host PC and devices with screw terminal interfaces. The adapter converts USB signals to a simple serial interface suitable for data exchange with industrial controllers, sensors, embedded systems and devices used for firmware programming. Its plug-and-play design enables quick connection where conventional COM ports are not available.
Advantages
The adapter offers a small form factor and standard USB 2.0 compatibility, allowing easy installation without additional hardware. Its screw terminal connection supports secure wiring of single-wire serial signals and grounds, providing a reliable mechanical and electrical connection for test setups and field devices. The solution reduces the need for custom cable assemblies and simplifies temporary or permanent serial connections.
Suitable for
 Connecting industrial controllers and PLCs to a PC for monitoring or configuration
 Interfacing sensors and measurement devices with screw terminals to a computer
 Embedded system development and firmware flashing where a simple serial link is required
 Laboratory and workshop test rigs that require a removable, secure serial connection
Key specifications
 Interface: USB 2.0 Type A plug to screw terminal serial connection
 Port configuration: single USB A plug to single screw terminal block
 Compatibility: standard USB serial operation for use with host PCs supporting USB 2.0
 Form factor: compact inline adapter suitable for benchtop and field use

How to use
Insert the RF-4951528 USB Type A plug into an available USB port on the host computer. Attach stripped conductors from the target device to the adapter's screw terminal and tighten the screws to ensure firm contact. Install any required drivers offered by the host operating system if automatic recognition does not occur; after driver installation, configure the serial port parameters (baud rate, parity, stop bits, flow control) in the host application to match the connected device. For firmware programming or terminal sessions, open the chosen serial communication software and select the newly created COM port.
Usage recommendations
The adapter is intended for low-voltage serial signaling and should be used with compatible devices. Verify signal levels and wiring polarity before powering connected hardware. For stable connections, use appropriately sized stripped wires and ensure screws are tightened without over-torquing. Avoid exposing the adapter to excessive mechanical stress, moisture, or conductive contaminants during operation.
