  Since IOC's and OPI's in different sub-net in your configuration,
you need set EPICS_CA_ADDR_LIST invironment variable. For more detail,
refer "EPICS R3.12 Channel Access Reference Manual" which  you can
get from APS WWW.

  R3.12.0Beta13CEBAF is CEBAF local customized (in devSup, recSup) version 
of R3.12.0Beta13 from APS CVS server. They should be no difference in 
channel access.
