USB Hub EXSYS EX-1344HMV Type-B Metallic

The EXSYS EX-1344HMV is a robust metallic USB hub designed to provide reliable COM port expansion for modern computer setups. Featuring a USB 2.0 Type-B host interface, this device integrates four high-performance 16C550-type UART compatible serial ports supporting RS232, RS422, or RS485 communication standards. Housed in a durable metal chassis, the unit offers LED indicators for operational status and data communication, ensuring clear visibility during active tasks. The package includes a secure screw-lock USB cable to prevent accidental disconnection, making it a dependable solution for professional environments.

Advantages

This serial hub delivers exceptional stability and secure connectivity thanks to its heavy-duty metal enclosure and screw-lock USB cable mechanism, which prevents the cable from slipping out during operation. It simplifies hardware expansion by offering instant COM port availability via the USB 2.0 bus without requiring internal computer modifications. The inclusion of versatile serial interfaces makes it adaptable to various industrial and commercial protocols, while the status LEDs allow for straightforward monitoring of data traffic and power functions.

Suitable for

• Connecting legacy serial devices to modern PCs and notebooks
• Industrial automation and control systems requiring RS232, RS422, or RS485 ports
• Expanding serial connectivity in professional office environments or server rooms
• Installation in 19-inch racks or on DIN rails using optional mounting accessories

This device may not be suitable for high-speed data transfer applications that require USB 3.0 or USB-C speeds, as the internal architecture operates on the USB 2.0 standard. It is also generally unnecessary for basic consumer setups that do not utilize legacy serial communication equipment.
