Stricter noise emission for residential and commercial areas
Background information: Since the mid-1990s, the PCI bus has developed to become the standard bus of state-of-the-art PCs. With the development of the CompactPCI standard which combines the electrical features of the PCI bus with the mechanics of the long-standing and well-proven 19" world, this tried and tested bus system can also be deployed in the industrial environment.
W&T converted all serial standard PCI cards to the CompactPCI format in such a way that no differences in using the cards are noticeable by users who switch from one PC world to the other. Independently of the relevant PC bus being used (ISA, PCI or CompactPCI), all W&T PC card ranges have an identical design with a subdivision into bus-specific elements and modular interface electronics. In that way, it is ensured for all bus systems that the peripherals can always be connected with the same cables and without exotic adapters or adjustments.
The realization of the cards with discrete interface modules also enables various different interface models (RS-232, RS-422, RS-485 or 20 mA) to be realized on a single board. This feature guarantees the optimum utilization of the in most cases small number of available slots in CompactPCI systems.
