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)
