Note: A total of 1023 base I/O address settings are available. The jumpers are a binary representation of the hexadecimal base I/O addresses. Jumper JP5/J is the Least Significant Bit and jumper JP5/A is the Most Significant Bit. The jumpers have the following hexadecimal values: jumper JP5/J=4000h, JP5/I=8000h, JP5/H=10000h, JP5/G=20000h, JP5/F=40000h, JP5/E=80000h, JP5/D100000h, JP5/C=200000h, JP5/B=400000h, JP5/A=800000h. Open the jumpers and add the values of the open jumpers to obtain the correct base I/O address. (closed=0, open=1) |
