Evgeniy,
At LANSCE, we have run two VSD 2992 serial highway drivers from the same crate without undo grief. We were only using a single processor, however (an MVME 167) and the two highways (which were both pretty heavily loaded) were a bit of a strain on the CPU, so we eventually moved the second highway to its own crate.
The EPICS Camac driver still uses "module_types.h", which is a bit anachronistic, but does have the advantage that all you have to do is set the two modules to different addresses (within the range specified by "module_types.h") and the software will automatically recognize both branches.
Hope this is helpful.
-Eric Bj.

We split our EPICS/CAMAC system into two loops.
Does anybody have experience with two Hytec VSD 2992 CAMAC serial highway drivers in one VME crate working with two MV162 in two different address spaces? Any problems? Can we save money by not buying second VME crate?
Evgeniy,
TRIUMF
