          |  Note:Node address 0 is reserved 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 most significant bit and switch|
          |  8 the least significant bit. The switches have the        |
          |  following decimal values: switch 1=128, switch 2=64,      |
          |  switch 3=32, switch 4=16, switch 5=8, switch 6=4, switch  |
          |  7=2, switch 8=1. Turn Off the appropriate switches and add|
          |  the values of the ‘off’ switches to obtain the correct    |
          |  node address.                                             |

          |      Note:LED2 will blink at a rate based on the NODE      |
          |      address. If the NODE address is low, LED2 will blink  |
          |      at a slow rate. If the NODE address is above 128      |
          |      then, LED2 will blink at a rate too high to be seen   |
          |      by the human eye.                                     |
