We are under the understanding that it may be wired using either of the (2) )combinations and using only (2) wires is this correct as well? thank you Bob Goodwin **** Hidden Message ***** Robert Goodwin 22191 Company: Terrestar Networks E-mail: rgoodwin@terrestar.com **** Hidden Message ***** rgoodwin@terrestar.com
