   | Note: A total of 63 station address settings are           |
   | available. The switches are a binary representation of the |
   | decimal station addresses. SW1/8 is the Least Significant  |
   | Bit and switch SW1/3 is the Most Significant Bit. The      |
   | switches have the following decimal values: SW1/8=1,       |
   | SW1/7=2, SW1/6=4, SW1/5=8, SW1/4=16, SW1/3=32. Turn on the |
   | switches and add the values of the switches to obtain the  |
   | correct station address.                                   |
