Note:The address range for the DCL-624 is from 0 to FFFFh. 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, SW1/7=2, SW1/8=1, SW3/1=8, SW3/2=4, SW3/3=2, SW3/4=1, SW3/5=8. Port 1 requires 8 consecutive address locations.
