# MoU Progress
+
## Elton has been pushing the MoU through the concurrence stage at JLab.
+
## Christina identified the officer who will read the MoU before the Vice Rector signs it and that person is expecting the MoU.
+
# Monitoring system evolution: (See Elton's email of March 15, 2011)
+
## Elton's email discussed modifications to monitoring system in order to use CAN bus system (same as for FCAL HV setting) and daisy-chaining.  Experience exists within Hall D group.
+
## Changes suggested now seem to require prototyping at the € 8,000 level.  Elton is pursuing a source of funds.
+
## Kapos will join us in a subsequent meeting to discuss all issues related to cables, etc.
+
## Fibre layout: Zisis will work with Dan to come up with a sketch which Elton will pass on to Chuck for inclusion in the drawings. (IDEAS dxf file format).
+
## Use 2 x 0.5mm fibres on each LED so that we have 4 SiPMs viewing 2 LEDS (increase redundancy). This idea is in principle decoupled from the board design, Question: how complex will the assembly be since the two fibres go to adjacent LEDs?
+
## Monitoring system concept is ''mature enough'' to be presented to CAL WG on Tuesday, March 29.  We will work on a proposal to show to the group.
