Note (1): The address range for the QS-200M/300M 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. The QS-200M/300M requires 32 consecutive address locations for all four serial ports.

Note (2): The base address selected above is for Port 1. To obtain the addresses for the other ports, add to the Port 1 address the following numbers:

Port 2 address = Port 1 address + 8

Port 3 address = Port 1 address + 16

Port 4 address = Port 1 address + 24
