   |     Note: A total of 256 base memory address settings are     |
   |     available. The jumpers are a binary representation of the |
   |     decimal memory addresses. JP2/A is the Most Significant   |
   |     Bit and jumper JP2/H is the Least Significant Bit. The    |
   |     jumpers have the following decimal values: JP2/H=4,       |
   |     JP2/G=8, JP2/F=16, JP2/E=32, JP2/D=64, JP2/C=128,         |
   |     JP2/B=256, JP2/A=512. Open the jumpers and add the values |
   |     of the jumpers that are open to obtain the correct memory |
   |     address. (Open=1, Closed=0)                               |
