2 Port Professional USB to Serial Adapter Hub with COM Retention


Availability: In stock



2-Port Serial Adapter Hub

The 2P2X2 Port Professional Grade USB Serial Adapter converts a single USB port to two RS232 serial ports allowing you to connect to, monitor and control your serial devices. Rugged metal construction and sturdy wall-mount brackets provide a robust solution for both harsh industrial environments and simple desktop installations.

Powered by USB, the device does not require a power outlet for most standard applications. For installations requiring power through the RS232 ports, optional DC connector and terminal block connections are included. Once connected, the adapter retains assigned serial COM port values, allowing the same values to automatically be re-assigned to the ports provided by the adapter in the event it is disconnected, then re-connected to the host computer.
