            Notes:Node address 0 is used for messaging between nodes and
            must not be used. A total of 255 node address settings are
            available. The switches are a binary representation of the
            decimal node addresses. Switch 1 is the Least Significant Bit
            and switch 8 is the Most Significant Bit. The switches have
            the following decimal values: switch 1=1, 2=2, 3=4, 4=8,
            5=16, 6=32, 7=64, 8=128. Turn off the switches and add the
            values of the off switches to obtain the correct node
            address. (On=0, Off=1)

                            MISCELLANEOUS NOTES

  The AL-3353 and the AL-3354 have different transceivers. As a result
  the AL-3353 should only be operated in a coaxial star configuration,
  while the AL-3354 will operate in a coaxial bus, a coaxial star, a
  twisted pair bus or a twisted pair star configuration.
