Product Description

When you have to connect serial devices to laptops or PCs with no serial ports, or when you have to connect a digital camera and a PDA at the same time, this adapter is the solution. Connecting USB with the traditional RS-232 serial port, this adapter connects cellphones, PDAs, digital cameras, modems, or ISDN terminal adapters through your USB ports. Has a data transfer rate of over 230 Kbps. Since the adapter uses no IRQs, there are no IRQ conflicts, and it is ideal for when you need many serial devices attached to your PC.

Gives you an additonal RS-232 port while it frees your RS-232 port for other uses. The plug-and-play functionality makes installation a breeze, while the adapter is bus-powered so no additional power source is needed. Plus, it's a lightweight travel tool; just throw it in your laptop bag and be on your way!

will this work in place of a switch box? i need to designate what gets tranfered to what machine... http://www.cablestogo.com/product/03289

Asked by: Chris
This will give you 2 different serial COM ports on one machine. If you need to share a serial device between 2 different machines, this would not work for you.

Will the COM port(s) be static / set? Or will they be dynamic and potentially change every time used?

Asked by: Anonymous
They will be static, but you can assign/change them in the Control Panel (Windows).
