|     Note: A total of 1023 base address settings are available. The jumpers  |
|     are a binary representation of the decimal memory addresses. W1/A is the|
|     Most Significant Bit and jumper W1/J is the Least Significant Bit. The  |
|     jumpers have the following decimal values: W1/A=512, W1/B=256, W1/C=128,|
|     W1/D=64, W1/E=32, W1/F=16, W1/G=8, W1/H=4, W1/I=2, W1/J=1. Open the     |
|     jumpers and add the values of the open jumpers to obtain the correct    |
|     memory address. (Open=1, Closed=0)                                      |
