Subject: Re: ADF->TAB working!

Hi Mike,

Thank you for digging into what was going on.

An intermediate step before trying pseudo-random data is to have
the ADF-2 send its fixed "pallet pattern".  This is still a fixed
data pattern, i.e. the same data in every ADF to TAB Frame,  but
instead of just being alternating 1's and 0's it has a different
fixed value of Et Energy for each of the 16 Trigger Towers.

These fixed Et values were picked so that they are an identifier
of which TT that value belongs to.  For example the TT that is
relative eta,phi 3,2  has a fixed Et value of 0x32.  The point
of this test is that it does not require fancy synchronization
but still lets us verify that all the data from the 16 TT's
handled by an ADF-2 card is transmitted correctly and lands in
the right spots in the TAB.

Thanks again for pushing on this.  It is a nice step forward.

        Dan
