Worth knowing

For years the RS232 interface has been established as a proven interface for connecting serial terminal devices over short and medium distances. In order to be able to use this reliable standard into the future, Wiesemann & Theis offers the USB<>RS232 Interface Cable 2 as a converter in the form of two meters of connection cable which enables connecting your RS232 devices even to computers which do not provide a serial interface.

The converter fulfils the industrial noise immunity standard specification EN61000-6-2 and the emission standard specification EN55022B. For that reason, despite its miniature design and its attractive price, the interface cable can be deployed without restriction not only in the industrial environment but also in the office domain.
