<p class=MsoPlainText><font size=2 face="Courier New"><span style='font-size:
10.0pt'>Regarding the terminator boards in the end slots: While yes, you could
do that I suppose, you would be using up 2 of our 6 slots. If you needed to add
termination to support a different bus topology configured as multidrop or
multipoint you could just make sure your boards with the bus receivers had
termination provisions on them. That way you get your termination without
wasting slots for a board whose only purpose is to provide terminations….<o:p></o:p></span></font></p>
