Note:JP1 sets the address for port 1. The settings for JP2 through JP4 are identical and set the addresses for ports 2 through 4, respectively. A total of 128 base address settings are available. The jumpers are a binary representation of the decimal memory addresses. JP1/A is the Most Significant Bit and jumper JP1/G is the Least Significant Bit. The jumpers have the following decimal values: JP1/A=512, JP1/B=256, JP1/C=128, JP1/D=64, JP1/E=32, JP1/F=16, JP1/G=8. Open the jumpers and add the values of the jumpers that are open to obtain the correct memory address. (Open=1, Closed=0) | ||||||||
