[App_rpt-users] Multiple RTCM's

I can find no reference to the *name* (client1,2,3,4, etc) on the RTCM itself. So what differentiates one RTCM from another on a 2 node each with an RTCM configuration? I've created the separate stanzas in the voter.conf file, is it the password that differentiates them? These are both running in conventional mode, not voter mode? Or am I missing something else? Thanks in advance, Alan
