Control up to eight serial devices with your PC - and never lift a finger. Just set the Code Operated Switch II (COS II) to react to a control sequence of your choice - and walk away from everyday switching duties. Since each port can handle a variety of data rates and formats, you can mix older plotters with newer laser printers and fast (up to 19.2 kbps) async modems. When you use the COS II with printers or plotters, you can send your data to the best available output device without having to turn knobs, press buttons, or configure software. And when you set the COS II to look for a "pause period" before recognizing a control sequence, graphics files pass safely through the COS II without causing accidental switching. And what about industrial machinery or test equipment? Tired of the constant hands-on intervention it requires? Just connect it and the PC/terminal of your choice to the COS II. You'll be able to manage lathes, meters, controllers, and more from your office or data center. And if you write a program for the master PC that includes the COS II's control codes, the PC can manage those devices without your even being there. The COS II can convert between differing data rates, data formats, and types of flow control, and its 8-KB buffer preserves your data intact through these conversions. In short, the COS II has the flexibility to adapt to nearly any group of serial devices.
