Note:The address range for the MPI-600 can be set between 000h and 7F8h. The switches are a binary representation of the addresses. The switches have the following decimal values: switch 1=4, switch 2=2, switch 3=1, switch 4=8, switch 5=4, switch 6=2, switch 7=1, switch 8=8. Turn Off the switches and add the values of the Off switches to obtain the correct address. | ||||||||
