9300-USBS | Allen-Bradley Remote Access USB to Serial Adapter with 6ft Cable

The Allen-Bradley 9300-USBS is a USB to Serial communication adapter used for connecting devices with RS-232 serial ports to modern computers via USB. It enables communication between control systems, PLCs, drives, or HMIs that rely on serial interfaces. The adapter acts as a bridge to facilitate programming, data logging, or monitoring. It is widely used for legacy system integration with modern PCs. The device is especially valuable for maintenance engineers and field technicians. Its plug-and-play nature simplifies setup and troubleshooting.

The 9300-USBS is compatible with Allen-Bradley PLCs, HMIs, drives, and other RS-232-based controllers. It works seamlessly with legacy models that use serial ports for programming or diagnostics. It also functions with third-party serial devices requiring a USB-to-RS232 connection. Supported protocols depend on the connected device and driver. It is commonly used with RSLogix 500, Studio 5000, and DriveExplorer software. Compatibility also extends to any Windows PC with available USB ports.

Yes, the 9300-USBS is ideal for remote maintenance or configuration when combined with remote desktop software or industrial VPN tools. Once the USB port is shared via remote connection, users can communicate with serial-connected devices. This reduces the need for onsite visits and speeds up support. It enhances flexibility in distributed automation systems. Proper port mapping and secure connections are required for stability and safety. Remote use must respect IT security policies.

Yes, the 9300-USBS supports plug-and-play installation under most Windows operating systems. Upon connection, it installs a virtual COM port driver that allows software to access it like a standard serial port. The driver can usually be downloaded from Rockwell or is automatically detected by Windows. Once installed, no special configuration is required for use. It is recognized in the Device Manager under Ports (COM & LPT). Some applications may require setting the correct baud rate and COM port number.

Yes, the 9300-USBS is still in production and available from Rockwell Automation and authorized distributors. It remains a commonly used accessory for technicians working with older serial-based hardware. As many PLCs and HMIs still use RS-232 for programming, this tool remains relevant. There have been no end-of-life announcements as of the latest information. Users should periodically check Rockwell’s lifecycle status to ensure continued availability. The adapter is actively supported with documentation and driver updates.
