Black Box 1-Port USB to RS232 Converter

The Black Box IC199A-R4 is a USB to RS232 converter that gives any laptop or desktop a straightforward way to talk to legacy serial equipment through a standard USB port. By creating a reliable bridge between a USB connection and a DB9 interface, it removes the need for dedicated serial cards or older computers, making device integration much easier.

Once connected, the converter supports data rates up to 230 kbps, fast enough for point-of-sale transactions, configuration of industrial controllers, or field diagnostics on security cameras. All power comes from the host USB port, so there is no external adapter to carry or find an outlet for. Plug-and-play installation on a wide list of Windows versions means you can move from one workstation to another without hunting for special drivers.

In day-to-day use, the IC199A-R4 shines wherever a modern computer meets a trusted serial device. Retail teams can link a bar-code scanner or receipt printer to a new checkout terminal. IT staff can service older networking hardware that still relies on a DB9 console port. Field technicians can travel with one small adapter instead of a bulky serial-equipped laptop. Its design stays compact and lightweight, so it slips easily into a pocket, service bag, or tight equipment rack.

Whether you are extending the life of proven hardware or building a flexible test bench, this converter provides the dependable, hassle-free connection that keeps data flowing.
