Description
The EX-1331VIS USB to serial RS-232/422/485 converter in a plastic enclosure provides a serial RS-232, 422 or 485 high-performance UART 16C550 interface with 15-kV ESD surge protection and 2.5-kV optical insulation. It was developed to connect serial devices to the USB 1.1 to 3.2 Gen 2 bus of PCs, servers or workstations. The supplied EX-K1542V cable can be attached without a screwdriver to the EX-1331VIS using thumb screws. The EX-1331VIS can be installed on a support rail in a 19'' rack using the optional DIN rail kit (EX-6099).
