USB 2.0 to 8x RS-232/422/485 ports with Surge Protection & Isolation (FTDI Chipset)

The EX-1339HMVS USB 2.0 to RS-232/422/485 Converter in a metal case provides eight high performance RS-232, 422 or 485 serial UART 16C550 interfaces with 15KV ESD protection and 2.5KV isolation. It is designed to connect serial devices to the terminal blocks via the USB 2.0 to 3.2 Gen 2 bus of a PC, server or workstation. The supplied EX-K1542V cable can be attached to the EX-1339HMVS using knurled screws without the need for a screwdriver. It is therefore impossible to disconnect the cable yourself. Easy installation on the USB port means there is no need to open the computer and the converter can be installed while the computer is running. A DIN-Rail kit (EX-6099) is included, allowing the converter to be mounted on a DIN-Rail in a 19" rack. The EX-1339HMVS can be expanded by 14 modules. This allows you to connect up to 112 serial ports to your computer system.
