Note:The address range for the MPA-102 is from 0h to FFF0h. The switches are a binary representation of the addresses. When a switch is off, the corresponding bit is set to 1 and has the following decimal value: SW1/1=8, SW1/2=4, SW1/3=2, SW1/4=1, SW1/5=8, SW1/6=4, SW2/1=2. SW2/2=1, SW2/3=8, SW2/4=4, SW2/5=2, SW2/6=1. The MPA-102 requires 16 consecutive address locations. | ||
