The max char limit on EPICS_CA_ADDR_LIST is 80 for R3.12.2 epics.
Jeff Hill found that you also can use hex presentation as he stated
in the following:
----------------
ip address "128.165.32.255". I just discovered that
the IP address parser will also accept hexadecimal
so "0x80a520ff" results in the same ip address as
"128.165.32.255" while requiring only 10 characters
(not 14 characters)
-----------------
It should be just fit your seven addresses. Let me
know what is the result.
