Note:The address range for the QS-100M/ES-100M 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, SW2/1=2, SW2/2=1, SW2/3=8, SW2/4=4, SW2/5=2. SW2/5 is not used on the ES-100M. The QS-100M requires 32 consecutive address locations, and the ES-100M requires 64 consecutive address locations. |
