|     Note: A total of 2047 base address settings are available. The jumpers  |
|     are a binary representation of the decimal memory addresses. E1/A is the|
|     Most Significant Bit and jumper E1/J is the Least Significant Bit. The  |
|     jumpers have the following decimal values: E1/A=512, E1/B=256, E1/C=128,|
|     E1/D=64, E1/E=32, E1/F=16, E1/G=8, E1/H=4, E1/I=2, E1/J=1. Open the     |
|     jumpers and add the values of the open jumpers to obtain the correct    |
|     memory address. (Open=1, Closed=0)                                      |
