Figure 6.  

Twisted Pair Groupings for the PXI-2570

When using the SH200LFH-4xDB50F-C cable with the PXI-2571 the twisted pairs vary 
depending on the channel. For the first 50 Channels, each COM and its corresponding NO 
connection form a twisted pair. However, for the remaining 16 channels, the three components 
(NC, COM, and NO) are each twisted with a NC component from the first 50 Channels. For 
example, COM0 is twisted with NO0, and NC0 is twisted with NC50. COM1 is twisted with 
NO1, and NC1 is twisted with COM50. COM2 is twisted with NO2, and NC2 is twisted with 
NO50. Figure 7 illustrates how this pairing relates to the pins on the PXI-2571.
