Note: A total of 128 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. JA24 is the Most Significant Bit and jumper JA30 is the Least Significant Bit. The jumpers have the following decimal values: JA24=32768, JA25=16384, JA26=8192, JA27=4096, JA28=2048, JA29=1024, JA30=512. Open the jumpers and add the values of the jumpers that are open to obtain the correct memory address. (Open=1, Closed=0)
