This is essentially a hardware note but it has a wide enough effect
that I'm posting it to the general bulletin board. It describes my recent
major work on the CAMAC highways.
The main point here is to notify people of the change in case there are
any problems. I have already changed the main ACQ and calibration CAMAC lists,
and the CAM$CONFIG files [MACRO.SUPER.CURRENT.SCINT]ERPCONFIG_SMx.DAT (which
are used by the LUT loader).
Essentially, I put all the hardware in the same slots on all three
uVAXes, so that as far as the sicntillator system is concerned all three CAMAC
lists are the same. This is a _huge_ advantage when debugging and adding new
electronics. There are three exceptions to the sameness plan:
(1) North and South walls: on uVAXes 1 and 3 the ERP includes EQUIP 25 and 26
for the North and South wall muon and GC, and includes them in the
end-of-run GC read (EQUIP 31). The pmt HV monitor (EQUIP 56 and 60) also
knows about them.
(2) InterERP TDC: this sometimes occupies crate 5 and sometimes occupies
crate 6. This was done to minimize cable lengths.
(3) FMT/CSPAM/HIPT: the inter-supermodule trigger design causes there to be
more modules on uVAXes 1 and 3 than on uVAX 2.
(4) All the WFD calls point to specific supermodules rather than CAMAC crates
so they of course vary from SM to SM.
Here are the major changes:
(1) SM 1,3,5 ERP now occupies crate 5; SM 2,4,6 occupies crate 6.
This was done so lower number SMs always got lower numbered
crates, as was the case for the LIP, TOHM, and WFD.
(2) On uVAX 2 the FMT was given crate 1 and the TOHM was given crate 4
to agree with the other uVAXes.
(3) On uVAX 1 and uVAX 2 SM 1,3 TOHM was given crate 3 while SM 2,4
TOHM was given crate 4, to agree with the higher-SM
higher-crate idea shown on uVAX 3.
(4) Various individual pieces of electronics that had wandered from
their assigned slots were rounded up and sent back home.
(5) The TOHM was moved down to the end of the crate to make room for the new
attico cards.
(6) The North and South wall ERPs were installed to the supervisors lived in
slot 21 just as on the ret of the SMs.

Contact the US Physicist-in-Charge for changes; in general, one-of-a-kind
harware can be placed in uVAX2 Branch 2 Crate 2, working from left to right,
and new hardware that lives on all three uVAXes should occupy the same crates
and slots everywhere to preserve the standardized CAMAC mapping.

History:
Nat Longley 18 JUL 95: Swapped uVAX 1-3 ERP crates and uVAX 1-2 LIP/SMT
crates to lower numbered SM would always have lower
numbered crate.
Nat Longley 01 JUN 95: Reallocated addresses to make crates identical (mod
SM number) on all uVAXes, with the following four
exceptions:
(1) InterERP TDCs are in either crate 5 or crate 6;
(2) Pulser GPIB interface is in uVAX 2 crate 7;
(3) North/South ERP & SMT are in uVAX 1/3 crate 2,
while crate 2 is unallocated on uVAX 2; and
(4) Inter-SM CSPAM/FMT/HIPT on uVAX 1,3 (not 2).
In addition, within uVAXes, crates 3/4 and 5/6 are
identical (mod SM number) except for #1 above.
Kate Scholberg 18 OCT 94: Ref ADC on SM 6 had been installed in a different
slot from the original assignment-- changing
allocation here.
Kate Scholberg 02 JUN 94: All new SMT (LI/TOHM) modules will now take up 6
slots instead of 5. Modules shifted over
accordingly.
?? 20 OCT 93: LIP modules moved over to be at the ends of the
crates (to accomodate ribbon cables), and other
modules shifted accordingly. Also, LI/TOHM display
module slots not needed, and changes to N/S face
ERP position.
