Evidently they have redesigned the RMC-1000 since mine was built 10 years ago.  Mine definitely uses 120V on the control lines.  I had considered reworking it for 24V but didn't, I guess they did!

Good news on the cable.  I just heard back from Remi the engineer at 
US Tower.  He states,

"The cable needed for the RMC1000 is a 7~8 conductors #22.  It does 
not carry 120V.  It can run in the same conduit with the other cables."

Remi has been terrific to me by the way.  He is the shining light at 
US Tower.  The company apparently has a brisk commercial business and 
perhaps hams are well down the list of valued customers.  Time will 
tell and I will report back on my experience.  Howard W6HDG
