The EX-1335HMV USB to Serial RS-422/485 enclosure provides a serial RS-422/485 high-performance UART 16C550 port with a 9-pin or terminal block connection, featuring 15KV surge protection and 2.5KV optical isolation. It is designed to add an additional serial RS-422/485 output in a compact metal housing for PCs, workstations, or servers via the USB 1.1 or 2.0 bus. With easy installation, there is no need to open the computer, and the EX-1335HMV can be installed while the system is running. The included EX-K1542V cable with A-type to B-type connector can be secured to the EX-1335HMV using thumb screws without the need for a screwdriver, preventing accidental disconnection. Optionally, the EX-1335HMV can be mounted on a DIN rail in a 19" rack using the EX-6099 (DIN-Rail Kit).
