AOB8/16 &AOB16/16 Manual
The AOBx/16 base address bits A5 through A9 are set by DIP switch S1. The setup program
provided on diskette with your card includes an interactive base-address selection program. The
computer monitor presents a pictorial display of the DIP switch and, when you enter your desired
hex base address, the display changes to show proper switch settings for that address.
To understand how this works, consider the following. In order to select the base address, convert
the desired address to binary form. Then for each “1” of binary address set the corresponding DIP
switch to OFF, and for each “0” of binary address set the corresponding switch to ON.
Here’s an example showing how to program the base address to hex 300:
1. Convert hex 300 to binary
300 (hex) = 11 0000 0000 (binary)
2. Set the Address Selection DIP Switches
The AOBx/16 card occupy 16 and 32 bytes of I/O address space, respectively. Address lines A5
through A9 are used to select the base address via DIP switches marked with the same names.
Address lines A0 - A4 are used to address registers at the digital-to-analog converters and there are
no DIP switches for these five lines.
