<p>14.30 Saved nnaida1-16 ASIC + Waveform configurations to directory (Data Base Key)</p>
<p> 2015Feb23-12.11.40</p>
<p> (directory aidas1:/MIDAS/DB/EXPERIMENTS/AIDA/2015Feb23-12.11.40)</p>
<p> nnaida 1-2, 5-6, 9-10, 13-14 positive input ( front p+n junction strips )</p>
<p> nnaida 3-4, 7-8, 11-12, 15-16 negative input ( back n+n ohmic strips )</p>
<p> </p>
<p> Standard ASIC configurations <strong>except</strong></p>
<p> - shaping time 0xb (6,5us)</p>
<p> - peaking time 0x8 (16us)</p>
<p> - slow comparator 0x10 (~160keV)</p>
<p> - fast comparator (LEC/MEC) 0xff</p>
<p> - fast comparator (HEC) 0xff</p>
<p> </p>
<p> nnaida 1-2, 5-6, 9-10, 13-14 negative input ( AIDA ASIC preamp output inverts input,</p>
<p> i.e. preamp with positive input produces negative input for sampling ADC )</p>
<p> nnaida 3-4, 7-8, 11-12, 15-16 positive input</p>
<p> Standard Waveform configurations <strong>except</strong></p>
<p> - threshold 1000</p>
<p> - pre-trigger 0x100</p>
<p> - all channels disabled</p>
<p> </p>
<p> 2015Feb23-12.11.40 is now the <strong>default</strong> configuration file</p>
<p> </p>
<p>Note: The directory (Data Base Key) which will contain the saved settings is created uid: npg, gid: npgstaff, perms 755.</p>
<p>However, its contents are written uid: nfsnobody, gid nfsnobody, perms 777. The default directory (Data Base Key) permissions</p>
<p>do not work - it is necessary to change the directory (Data Base Key) to perms 777 <strong>after</strong> its creation and <strong>before</strong> saving the</p>
<p>individual FEE64 configuration directories/files to it.<br />
