2 Port USB to RS232 /422 / 485 Adapter for Windows Linux and Mac

EOL NOTICE
This product is End Of Life effective Jan 1, 2018.

The 2 Port USB to RS-232 / RS-422 / RS-485 Serial Adapter supports Windows, Linux, and Mac systems that can support USB 2.0 port connections so existing serial devices can be used. The USBG-2COM-PRO is extremely flexible in offered communication standards.

The Industrial PRO Line supports flexible RS232, RS422, and RS485 port communication. Each port can be individually configured by software (No Jumper). The ports have standard DB9 male connectors. The industrial-grade metal chassis can be easily used for DIN-Rail mounting, the 8-Port and 16-port versions also fit in a 19″ rack mount.

The USBG-2COM-PRO 2-Port USB to RS-232 adapter with the 128 byte FIFO allows high-speed communication, even in heavy loaded systems. It’s unique features reduce the system load and also allows unusual speed settings like 500.000bps. A wired connection option via two(2) 5-pin Terminal Blocks is available on both sides of the serial adapter for use in easy wiring of devices.

Additional Features:

• Adds two RS-232, RS-422 or RS-485 serial port by connecting to a USB port
