## Long description

The EXSYS EX-1338HMV USB 2.0 to 8S Serial RS-232 Ports Adapter is a metal-enclosed device that expands a PC, thin client or server with eight RS-232 serial COM ports over a USB 1.1/2.0 connection. Each port is implemented with a high-performance 16C550-type UART compatible buffer and the adapter is powered either from the USB bus or by an external screw-lock power supply. The unit includes a 2 m A-male to B-male USB cable with screw-lock connector and can optionally be mounted in a 19-inch rack using the EX-6099 DIN-rail kit.
Advantages
The adapter provides instant COM port expansion without opening the host system and supports hot-plug installation. Its robust metal housing and included screw-lock USB cable prevent accidental disconnection and improve reliability in industrial or office environments. The device uses a proven FTDI-based chipset and complies with CE, FCC, RoHS and WHQL standards for compatibility and safety.
Suitable for
Connecting legacy serial devices (modems, barcode scanners, POS terminals) to modern PCs or thin clients
Industrial or laboratory equipment integration where multiple RS-232 ports are required
Server environments requiring compact external serial port expansion

After driver installation the new COM ports are assigned by the OS and are available for serial communication software without opening the host system.
Usage recommendations
For stable operation in industrial environments, secure the adapter in a fixed location and use the screw-lock USB cable and optional EX-6099 DIN-rail kit or rack mounting to prevent mechanical strain on the connectors. Verify driver compatibility with your operating system and configure interrupt and I/O settings via the OS or BIOS only if needed.
