A pool of existing modules

From the area " PC slot cards ", a PCI interface is directly available for the assembly of PC slot cards for the PCI bus. It was implemented by a FPGA. Also available are counter and register modules as well as modules for generating Interrupts. The connection to a computer's peripheral devices can also be created in various ways. It is particularly problematic, above all, in the industrial network, since external voltages and malfunctions can easily get into the computer. The galvanic separation prevents this. It can either take place via opto couplers, by which the information is transferred by light, or via relays, by which the signal status is transferred mechanically. However, relays are recommended only with slow data transmission rates, like when switching devices. Despite the older technique, relays still offer sufficient areas of application, since, by lower switching speeds, the data stream can be very fast over the contact. By use of the galvanic separation, it is furthermore possible that the computer's and the system's, which is to be controlled, voltage offset differ by several hundred Volts without having a compensating current or that the operational reliability is influenced. Ready made function modules also exist for this area, which, depending on the requirements, are either to be inserted in the switch or to be interchanged.

QUANCOM also works with modules on a software-base. We offer the development of drivers for various hardware. For the consumer, the development of drivers for the operating system Windows NT is particularly interesting, since in correlation with a higher speed, hardware access problems often occur. Special test- and visualization programs, which operate or test available hardware components, are also frequently needed. Due to the varying requests, modules can not always be used. However, in this case we develop completely new and economical solutions.
