Please be more specific with your question. Is there a certain RS-170 camera that you have in mind, or do you just want general information about RS-170 video signals? If it's the latter, you may find the following website useful: <a href="http://www.epanorama.net/documents/video/rs170.html">ePanorma.net: RS-170 Video Signal</a>.
I assume that by the second half of your question, "any other attachment about camera to the imaq acquisition ni pxi-1409", you are asking how to connect an RS-170 camera to an IMAQ card. Fortunately analog cameras have a simple cabling standard that uses a single BNC cable to connect the camera to the framegrabber. National Instruments also sells additional cables and breakout boxes that allow you to access trigger and external digital I/O lines. Please refer to the following resources for more information on these cabling options: <a href="http://digital.ni.com/public.nsf/websearch/6D42B3441B3B210986256DD300749DE3?OpenDocument">Knowledge Base 332E7RDI: What is the appropriate Cable and Connector Block for my IMAQ Device?</a> and <a href="http://sine.ni.com/apps/we/nioc.vp?cid=1294&lang=US">NI Product Page: PCI/PXI-1409 and Cables</a> I hope this helps!
