EXSYS EX-1339HMV USB 2.0 to 8-Port RS-232/422/485 Serial Hub, Metal

The EXSYS EX-1339HMV consolidates eight serial ports into a single USB 2.0 connection, supporting RS-232, RS-422, and RS-485 standards per port. Its metal housing and 2.5 kV optical isolation suit industrial environments where electrical noise and ground loops are common.

Highlights

• 8x DB9 male serial ports, each configurable for RS-232, RS-422, or RS-485
• USB 2.0 Type-B upstream, backward compatible with USB 1.1
• FTDI chipset with drivers for Windows, Linux, and macOS
• 15 kV ESD protection and 2.5 kV optical isolation
• Metal housing, wall mountable, optional DIN-rail kit

In daily use

Connect legacy serial devices such as barcode scanners, PLCs, or industrial sensors to a modern computer. Each port operates independently with baud rates up to 921.6 kbps. The external 9–24 V DC power supply (included) ensures stable operation even when all ports are active.
