Notes about MVD hardware address
The format of MCM data packets is given here. The format of DCIM data packets is given here. From the DCIM, the packets go the the DCM, which adds further framing information as described here. The event builder home page also describes the frame format -- which appears to contain additional stuff wrapped around the DCM packet.
The information needed to associate a particular MCM/Si-detector with the packets is not conveniently organized. This information is as follows:
From the combination of these pieces of information and careful cabling, the DCIM output packet can be used to determine which MCM is came from.
There was a request (maybe a rule?) that the packetID values be consecutive and
start from 1. This makes it impossible for us to use a numbering system
for packetIDs which is both
1) The same in year-1 and later years
2) related in a simple was to the r,phi,z position of the detector element.
I propose to keep the same general organization (as in year-1) of the packetID numbers. The barrel data come first, then the pads. Within the barrel the z index runs fastest, then phi, then shell. Within the pads the phi index runs fastest and the z index is next.

In the tables above, the DCM cable number is the number
on the fiber-optic cable which goes from
a) the DCIM output to the patch panel on the west side
on the central magnet
b) the patch panel in Bldg 1008 to the DCM
The cable numbers are the same in the two places.
Comments and suggestions appreciated.
