## Summary description

Steel housing in black with LED activity indicators; supports USB-powered operation. Designed for DIN‑rail or wall mounting for industrial and server-room installations.

## Long description

The StarTech 4-Port USB to DB9 RS232 Serial Adapter Hub ICUSB2324I converts a single USB 2.0 Type-B connection into four RS232 DB9 serial ports in a compact, rugged steel housing. Designed for industrial and server-room environments, the adapter provides LED activity indicators and supports USB-powered operation, enabling connection, monitoring and control of multiple serial devices from one host. The unit is compatible with a range of Windows, Mac OS X and Windows Server versions and features mounting options for DIN-rail or wall installations. Its compact footprint (59 × 23 × 178 mm) suits space-constrained setups.
Advantages
The adapter offers four independent RS232 ports in a single device, preserving assigned serial COM port values so ports are automatically reassigned consistently when reconnected. Its all-steel enclosure and integrated mounting hardware (wall brackets and DIN-rail clips) provide mechanical protection and flexible installation options for industrial racks and control rooms. LED indicators make it easy to verify port activity and the USB-powered design simplifies deployment where an external power outlet is not available.
Suitable for
 Connecting multiple RS232 sensors, controllers or instruments to a single USB host
 Industrial automation cabinets and DIN-rail installations
 Server rooms and network equipment racks with limited space
 Field service and diagnostic work where portable USB-powered serial access is required
Key specifications
 Interface: USB 2.0 Type-B host to four DB9 RS232 serial ports
 Power: USB-powered (no external power adapter required)
 Enclosure: Steel housing, black finish
 Mounting: Integrated wall-mount brackets and included DIN-rail clips
 Indicators: LED activity indicators for serial ports
 Compatibility: Supports multiple Windows, Mac OS X and Windows Server versions
 Dimensions: 59 × 23 × 178 mm (compact footprint for constrained spaces)
How to use
Connect the adapter to your host PC or server using a USB 2.0 Type-B cable, then attach up to four RS232 DB9 devices to the serial ports. Mount the unit on a DIN rail or attach it to a wall using the integrated brackets and included clips as needed for your installation. Install any required drivers or follow the host operating system prompts for plug-and-play recognition; the adapter retains assigned COM port values to maintain consistent port mapping across reconnections.
Usage recommendations
Place the adapter in a dry, vibration-minimized location within your cabinet or on a DIN rail. Ensure USB cable runs are secure and avoid routing near high-voltage or high-noise power sources to reduce potential serial communication interference. For installations requiring persistent COM port assignments, configure the host operating system or device manager settings as appropriate to preserve port mappings.
