from John's email:
When you turn on the VME crate the MVME5500 processor performs its initial bootstrap and then goes out and loads a “command file” – this is basically like AUTOEXEC.BAT on a PC, a text file with a bunch of console commands. That “command file” will load some EPICS “database” files from a remote server. To edit the PVs we need to know what machine the MVME5500 uses as the remote boot host and where in that machine’s file structure the database file is located.
If you open up a terminal window to your trigger crate’s IOC console and enter the command ‘version’ it should print out some stuff about what version of VxWorks it is running and then say “Boot line:” followed by a path to a file. For instance the DGS trigger IOC says it’s boot line is
dgs1:/global/devel/boot/mvme5500/VxWorks <then a bunch of IPs and other junk, then finally> s=/global/devel/gretTop/9-22/dgsIoc/iocBoot/IocArray/vme32.cmd
It’s that last path after the “s=” that you’re interested in. That’s the location of the boot script for the processor. You want to look at that file to figure out where the EPICS database is stored for your system.
Inside that file you’ll find some lines that say dbLoadRecords(<path>,<args>); these are the actual database files. They should have an extension of either .template or .db. More than likely there are some ‘cd’ commands prior to these lines and the paths in the ‘dbLoadRecords’ lines will be relative to the place the last ‘cd’ took you. I would expect there to be a file RtrigRegisters.template.
At this point you know where the files are, but modifying them may require a recompile of your EPICS setup. So before going farther I will suggest that it is possible you have the PVs.

router lock state
it is a 16bit hex number. for example, a good lock state is 17668 = 0x4504 = bx0100 0101 0000 0100
The bit is read like this: ( first bit is the most left bit )
bit-01 | Lock Error | 0 bit-02 | All Lock | 1 bit-03 | not use | 0 bit-04 | not use | 0 bit-05 | L init state 8 | 0 bit-06 | L init state 4 | 1 bit-07 | L init state 2 | 0 bit-08 | L init state 1 | 1 bit-09 | CPLD 8 | 0 bit-10 | CPLD 4 | 0 bit-11 | CPLD 2 | 0 bit-12 | CPLD 1 | 0 bit-13 | Fast str | 0 bit-14 | R Lock | 1 bit-15 | NIM in A | 0 bit-16 | NIM in B | 0
