The base address is set up by JUMPERS. Those jumpers control address bits A2 through A9. (Lines A1 and A0 are used on the board to control individual registers. How these two lines are used is described in the Programming section of this manual.) Manual 104-IIRO-8(E) - Page 12 Binary Representation Jumper Legend Addr. Line Controlled Jumper Selection Carefully review the address selection reference table on the preceding page before selecting the board address. If the addresses of two installed functions overlap, you will experience unpredictable computer ehavior. Manual 104-IIRO-8(E)

Digital input states are read as a single byte from the port at Base Address +3. Each of the eight bits within the byte corresponds to a particular digital input. A "1" signifies that the input is high and a "0" signifies that the input is low. Bit Position Digital Input Manual 104-IIRO-8(E) - Page 14 Each time it sets a new bit, both the relay output and the relay input are read and the data displayed. This demonstrates how to read and write to a port. BSAMPLES: SAMPLE1Same sample in Quickbasic Manual 104-IIRO-8(E)
