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. PORT 2 I/O ADDRESS CONFIGURATION Base Address SW2 SW4 » 2F8h 1, 3, 4, 5, 6 & 8 6 on on 3220h 1, 2, 5, 6 & 8 on 1, 2, 4, 5 & 6 on 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: SW2/1=8, SW2/2=4, SW2/3=2, SW2/4=1, SW2/5=8, SW2/6=4, SW2/7=2, SW2/8=1, SW4/1=8, SW4/2=4, SW4/3=2, SW4/4=1, SW4/5=8. Port 2 requires 8 consecutive address locations.
