Scope pictures of Data Lines 
----------------------------

   Use "Aurelio" termination: 22 ohm series + 82 ohm to ground on svx side of
interface board. The resistors were chosen based on what we had in stock.
Aurelio wants 24 ohm and 91.

   Check signals on input to transceiver (U20) on interface board #2, channel B.
   Chan 1 = dvalid (trigger)
   Chan 2 = data line

Signal    pin#
------    ----
D7        pin 12
D0        pin 1
etc

  Remarks: signals well shaped, with no reflections apparent and average 2.4V.
 On RunCheck get exactly one error per event, which is
the chip ID of the 1st chip readout. This loss is also occurring in the
EXCEL spreadsheet. 


    Due to operator error, transceiver was fried before completion.
