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)
