Week Two

02 June:
Received new computer from Mark Jones. No network card present. Single hard-drive with Red Hat previously installed. Functioning version of CODA present (at least previously used). Going to attempt use with 2TB hard-drive from Alexandre. Need to install the SRS software and SLC5 from the ground up, complete fresh start.

03 June:
New hard-drive appears to dislike the CNU PC. Unusual problem arises when booting, kernel and OS appear to begin loading but screen goes black half-way through boot (never seen before). Hard-drive functions properly on other computers. Going to continue tests from my personal computer. Will have to return to this PC when I understand the boot issue.

04 June:
SLC5 and SRS software installed and properly running on personal computer. Able to ping the FEC and ethernet port without issue. Still not able to receive triggered events from the FEC. Possible that the trigger signal coming from the gate generator is not suitable but this is unlikely, from an oscilloscope the signal looks appropriate in amplitude and width. FEC definitely set to trigger from NIM input.

05 June:
Issue with receiving triggered events, turned out to be a firewall problem. During install firewall was set to automatically start with boot. Either need to disable completely or run the command (/etc/init.d/iptables stop) on startup. Requires root authority. See Overview of DATE Setup and Troubleshooting document for more detail. Gate generator provides proper trigger, though finding a suitable rate and having to hold trigger button can be frustrating. New problem is the message flood error. Going to consult Filippo Costa at CERN, I've never seen this issue before.

06 June:
When Message Flood occurs DATE appears to be outputting more info about the error to the directory (/dateSite/LogFiles/). Under inspection files seem to indicate that the FEC is mismatching ADC channel information. As an example, when attempting to read ADC channel 4 it gets info from 8. In some cases all ADC channels will display the same information from a single channel. This causes some horrible data when the ADC channel is not connected to an APV. Have contacted Filippo about the problem. Not sure how to or where to begin with troubleshooting.
