Hello...I have a couple of questions about LGB's wireless receiver. When I bought the receiver, there were two cables supplied with it. The cable with narrow (4/6) phone style connectors goes from the receiver LGB Bus to the Central Station's LGB Bus. What I haven't figured out is were the other flat cable with the wide (8/8) phone style connectors are used for. The second question concerns the first cable with the narrow connectors. Is this cable wired like a standard phone cable (the type that runs from the phone to the wall.) Thanks
