The Hewlett-Packard 10895A is a VMEbus laser axis board for laser interferometer measurements. This device support provides access to the board’s status, position, control, and command registers through bi, bo, mbbi, mbbo, longin, and longout records.
An iocsh script is provided that handles configuration and database loading:
iocshLoad("$(VME)/iocsh/HP_10895A.iocsh", "PREFIX=xxx:, INSTANCE=hpla:, VME=$(VME), ADDRESS=0x1000")
Macro Required Default Description PREFIXYes – IOC prefix INSTANCEYes – Instance prefix VMEYes – Location of vme module ADDRESSFirst call – A16 base address MAX_CARDSNo 1 Total number of cards CARDNo 0 Card number
The script calls devHPLaserAxisConfig(ncards, a16base) and loads HPLaserAxis.db. When configuring manually:
devHPLaserAxisConfig(1, 0x1000)
dbLoadRecords("$(VME)/vmeApp/Db/HPLaserAxis.db", "P=$(PREFIX),Q=$(INSTANCE),C=0")
All record types use DTYP "HP interferometer" with VME_IO link type.
