12/30/03 Removed AM-A, installed VME crates for TWR system. Installed TWR DL380 computer on network. Installed 576 lemo cables between TWR and SWAMPS and ORBs. Connected to fast out.

1/23/03 Installed crate 5 of TWR system. Re-arranged ~40 lemo cables to each channel. Removed cables from string 17, dead OMs, and optical channels that are now readout as electrical.

1/30/03 Solved problem with occasional crashing of TWR system Problem was in DSP code

2/05/03 Read-out of all channel implemented in MBS. (Prior to this only 4 VME crates of TWR channels were read-out, even though 5 VME crates were connected to channels.

2/07/03 Added two TWR modules to bring the number of channels to 576. Re-mapped cables to ~30 OMs to include Strings 1 and 2.

2/11/03 Discovered that many waveforms were exact duplicates. Error traced to logic of DSP code. New code developed by SIS and Karl Heinz on 2/11, implemented by W. Wagner, 2/11. New code was certified to work by W. Wagner on 2/11.

2/12/03 Discovered error which caused blank waveforms on approximately 30% of the valid waveforms. Error randomly affected all OMs. Problem traced to improperly set bit in TWR (this was a new bit that was not documented in the manual we have at pole. It was only discovered in conversations with SIS. The latest manual has this discription).

2/13/03 Adjusted thresholds of each channel so that P/V (using integrated charge) is visible, if possible. Prior to this the electrical thresholds were 180mV, much too high. The reason for the initial high values was to keep the data rates small. Adjusted delay in start time for each TWR module. Goal: set delay so trigger peak (the narrow line in LE distribution that is generated when the OM is the module that forms the M=24 trigger) in each OM is about 3us after the beginning of the waveform.

2/14/03 Put TWR system in final state for winter operation.
