Notes about MVD hardware address (year-3)
Versions of this document for earlier runs are different. The year-1 version of this document is different, Look here to the year-1 version. Look here to the year-2 version.
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 each year as channels are added to the MVD
2) related in a simple way 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.
Look here or here to see the first version of the "pcf" file which is used by the DCMs to relate the DCM slot and input number to the packet number.
Look at this pdf file or this powerpoint file for sketches of the locations of the packets and notes about current performance.

Note added 3-Feb-2003: For the pads, I got confused about East and West when I originally defined this table. As a result, the packet numbers do not have a simple relationship with the phi and z location. However, it seemed to be too much trouble to change the packet numbers at this time. The only thing which differs between this table and the old (wrong) table is the column labeled "phi". If you really want to know the old (wrong) phi address, you can calculate it -- in every case (old wrong phi address) + (new correct phi address) = either 5 (for new or old address less than 6) or 17 (for new or old address 6 or greater). For example, NE pad 4, new address = 5, therefore old wrong address was 5-5 = 0. SW pad 1, new address = 8, old wrong address was 17-8 = 9.

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
