Overview

3 Overview

The Kram er VS-41USB is a high quality 4x1 USB mechan i cal sw it che r. It accepts
up to four USB inputs and switches the selected input to the output. Its
unpowered design is advantageous for applications i n wh ic h various
regulatory compliances would ot herwise be required.

Achieving the best performance means:

• Connecting only good quality connection cables

1

• Avoiding interference from neighboring electrical appliances and

positioning your VS-41USB away from moisture , excessive sunlight and
dust

, thus avoiding
interference, deterioration in signal quality due to poor matching, and
elevated noise levels (often associated with low quality cables)

1 It is recommended to use USB 2.0 type cables for improved performance
