          |      Note:A total of 63 node address settings are          |
          |      available. The switches are a binary representation   |
          |      of the decimal node addresses, and have the following |
          |      decimal values: 1=1, 2=2, 3=4, 4=8, 5=16, 6=32.       |
          |      Switches in the off position maintain a zero value.   |
          |      Sum total the switches in the on position to obtain   |
          |      the correct node address. Node 0 is a non-valid       |
          |      address.                                              |
