However MITE based VXI controllers such as the VXIpc 870 Series free up CPU processing time by moving the burden of block data transfers to one of the DMA controllers integrated in the MITE Instead of the computer microprocessor transferring the data and or commands the NI VXI VISA software uses the MITE ASIC to execute the block data transfers While the MITE transfers the data the processor can perform application specific tasks such as data presentation and analysis VXI Slot 0 Functionality The VXIpc 870 Series computers have full VXI Slot 0 capability including a MODID register and a CLK10 source as required by the VXIbus specification You can also install the VXIpc 870 Series in another slot and use it in Non Slot 0 mode No matter what your configuration needs the V XIpc 870 Series can automatically detect whether it is inserted into Slot 0 and automatically enable or disable the Slot O onboard circuitry without switches and jumpers 5 6 www ni com Chapter 5 Functional Overview External VXI CLK10 Synchronization The VXIpc 870 Series computers have an SMB connector on the front panel for an external clock Onboard programmable logic can configure the V XIpc 870 Series to drive its 10 MHz VXI CLK10 signal to this connector as an output or to use this connector as an input for the 10 MHz VXI CLK10 signal In this fashion you can configure multiple mainframes to operate off a single 10 MHz system clock All CLK10 routing fe

Communications Commission FCC has rules to protect wireless communications from interference The FCC places digital electronics into two classes These classes are known as Class A for use in industrial commercial locations only or Class B for use in residential or commercial locations Depending on where it is operated this product could be subject to restrictions in the FCC rules In Canada the Department of Communications DOC of Industry Canada regulates wireless interference in much the same way Digital electronics emit weak signals during normal operation that can affect radio television or other wireless products By examining the product you purchased you can determine the FCC Class and therefore which of the two FCC DOC Warnings apply in the following sections Some products may not be labeled at all for FCC if so the reader should then assume these are Class A devices FCC Class A products only display a simple warning statement of one paragraph in length regarding interference and undesired operation Most of our products are FCC Class A The FCC rules have restrictions regarding the locations where FCC Class A products can be operated FCC Class B products display either a FCC ID code starting with the letters EXN Gade Maine MOGEN or the FCC Class B compliance mark that appears as shown here on the right any ee FC with FCC Standards Consult the FCC web site http www fcc gov for more information FCC DOC
