Coolgear USB-8COMi-RM USB to Octal RS-232/422/485 adapter

Description

The adapter is designed with eight external 4-pin dip switches to set RS-232, RS-422 or RS-485 mode conveniently, without the need to open the metal chassis. Each port can be independently set to RS-232, RS-422, or RS-485, depending on your requirement in application. The adapter is with DIN rail bracket for industrial environment. The adapter can be also mounted to a 19" rack, and the rack mount kits are included with the adapter. Termination and biasing option are available for data transmission lines. The USB-to-Octal RS-232/422/485 Adapter provides instant connectivity to RS-232, RS-422, RS-485 communication devices for POS, factory automation equipment, multi-drop data collection devices, bar code readers, time clocks, scales, data entry terminals, PC to PC long distance communications, ATMs and serial communication in harsh environments. The USB-8COMi-RM USB to Industrial I/O provides industrial solution requiring single node or multi-drop communications over short and long distance.
