Board Address Selection Switches

There are two address select DIP switches on-board the Digital-to-Analog Converter Board. Each individual switch corresponds to an address bit, or is not used. If the switch is ON the corresponding address bit is compared to a logic "zero". All corresponding address bits must compare with the switch positions during a Write/Read of the DAC board. Each switch corresponds to the address bits as shown in Figure 2-1 below. For the board switch locations are shown in Figure 2-2 on page 2-6.

Example: For the Digital-to-Analog Converter Board to respond to a base address of (FXFFBC4016) the S1 and S2 switches would be set accordingly.
