    The CLK10 signal generated by the VXIpc 870 Series is ±100 ppm (0.01%) as per the VXIbus specification. If you need a more accurate CLK10 signal, you can use the CLKI/O connector on the front panel. © National Instruments Corporation VXIpc 870 Series User Manual...
  • Page 85 Appendix E Common Questions What if my keyboard connector does not fit into the keyboard port? You can plug keyboards that have a 6-pin PS/2 type connector directly into the VXIpc 870 Series. Your kit also includes a keyboard adapter cable that you can use to adapt the larger AT keyboard connector to the 6-pin PS/2 connector.
