Note: A total of 1023 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. W2/A is the Most Significant Bit and jumper W2/J is the Least Significant Bit. The jumpers have the following decimal values: W2/A=512, W2/B=256, W2/C=128, W2/D=64, W2/E=32, W2/F=16, W2/G=8, W2/H=4, W2/I=2, W2/J=1. Open the jumpers and add the values of the open jumpers to obtain the correct memory address. (Open=1, Closed=0)
