[quote user="Jake1210"][quote user="Don Z"] <p>[quote user="dadret"]Thanks for the information. I understand the arithmetic but where did the table for the numeric values of the different bits come from? I just spent a lot of time with the QSI manual and I can't find anything that resembles this. Pages 44 and 45 of the manual show recommended values for CV21 and C22 but there are just binary numbers. Is there another reference source I should be looking at?[/quote]</p><p><strong>The 8 bits have a predetermined value....they are:</strong></p><p><strong> bit7 bit6 bit5 bit4 bit3 bit2 bit1 bit0<br /> F8 F7 F6 F5 F4 F3 F2 F1<br /> 128 + 64 + 32 + 16 + 8 + 4 + 2 + 1 = 255</strong></p><p>When you are adjusting the CV, you are simply 'turning on or off' the specific bit within the CV that you want to alter. That is represented by the example on page 44 of the manual. You add the numeric value for each bit that is turned on and that numeric value is what you enter into the CV value.</p><p>Does this help?</p><p>Don Z.</p><p>[/quote]</p><p> </p><p>So if I'm getting what you are saying, each bit has a value double of the on preceding it, and half of the one after it? In other words, progressive doubling?</p><p>[/quote]</p><p>No.</p><p> 11111111 = 255</p><p> 11111110 = 254</p><p> 11111101 = 253</p><p>and so on.</p><p>What number do you think this one is?</p><p> 11000001</p><p>Take out your desktop calculator on your computer.</p><p>Open it up.</p><p>Set view to scientific.</p><p>Enter your number.. like 253</p><p>Change your value from Dec to BIN for BInary and it should come up properly. And vice versa.</p><p>Hex is for Hexdecimal and it is possible to jump among all three groups.</p>
