USB 2.0 to 1x Serial RS-422/485 Port with 15KV Surge Protection and 4.0KV Optical Isolation

The EX-1346IS provides one RS-422/485 high performance UART 16C550 serial port with 15KV ESD surge protection and 4.0KV optical isolation. It is designed to add another serial port for PC, small workstation or server via USB 1.1, 2.0 or 3.2 bus. It is the perfect solution for connecting barcode scanners, card readers, scales, etc. Due to the easy installation, the system does not need to be opened and the EX-1346IS can be installed while the system is running. Furthermore, a 9 pin female to 5 pin terminal block adapter is included.

The EX-1346IS supports COM memory which retains the COM port setting for the serial devices when plugged in and unplugged. Once assigned, COM port values are saved and automatically reassigned correctly after plugging in and unplugging. This also applies when switching between different USB ports.
