## Summary description

Industrial 8‑port StarTech USB 2.0 to DB9 serial hub (model ICUSB234858I) provides RS232/RS485/RS422 connectivity for multiple serial devices via a single USB host. Steel IP30 housing is DIN‑rail mountable and includes power LEDs, AC input (100–240 V) and typical consumption 36 W. Offers 15 kV ESD protection and cross‑platform driver support for Windows, macOS and Windows Server — suitable for industrial automation, POS, instrumentation and legacy device integration.

## Long description

The StarTech 8-Port Industrial USB 2.0 to DB9 Serial Hub (ICUSB234858I) converts a single USB host connection into eight independent serial COM ports supporting RS232, RS422 and RS485 protocols. Designed for industrial environments, the device is housed in a steel IP30-rated chassis with DIN-rail and wall mounting options, integrated power LEDs and screw-locking host connections. It provides up to 15 kV ESD protection and supports cross-platform drivers for Windows, macOS and Windows Server. Typical power consumption is 36 W with an AC input range of 100–240 V, and high-speed UARTs enable data rates up to 921 Kbps in serial operating modes.
Advantages
The hub offers eight serial ports in a single compact unit, allowing multiple legacy or industrial devices to be connected to one USB port. A rugged steel IP30 housing with DIN-rail and wall mount options simplifies installation in control cabinets and industrial racks. Built-in 15 kV ESD protection and screw-locking connectors reduce the risk of communication interruptions in electrically noisy environments. High-speed UARTs support reliable, low-latency serial communication up to 921 Kbps across RS232, RS422 and RS485 modes.
Suitable for
Industrial automation controller connectivity and fieldbus integration
Point-of-sale systems, barcode scanners and receipt printers
Instrumentation, sensors and data-logging equipment
Legacy device integration and serial console access
LED signage and building management systems
Key specifications

Host interface: USB 2.0 with screw-locking USB-B connector
Maximum data rate: Up to 921 Kbps per port (UART)
Housing: Steel chassis, IP30-rated
Mounting: DIN-rail and wall-mountable (bracket included)
Power: AC input 100–240 V, typical consumption 36 W
ESD protection: 15 kV
Operating systems: Driver support for Windows, macOS and Windows Server
How to use
Mount the hub on a DIN rail or secure it to a wall using the included bracket. Connect the hub to your USB host using the supplied screw-locking USB cable and attach serial devices to the DB9 ports with appropriate DB9 cables. Apply AC power within the 100–240 V input range and verify the power LEDs to confirm operation. Install the required drivers for your operating system if they are not installed automatically, then configure COM port settings (baud rate, parity, stop bits, flow control) in your application or device manager to match each connected device. For RS485 operation, set the port mode to 2-wire or 4-wire as required by your network topology.
Usage recommendations
Keep USB and serial cabling separated from high-voltage mains wiring to minimize electrical interference. Use shielded, grounded serial cables where possible and secure screw-locking connectors to prevent accidental disconnection. When deploying in electrically noisy environments, verify grounding and install surge protection if required; check and match baud rate and protocol settings on both host and connected devices to ensure reliable communication.
