3. BOARD CONFIGURATION
Refer to the Drawing of Ruby-MM-1612 on Page 8 for locations of headers described in Chapters 3 and
4.
Base Address
Each board in the system must have a different base address. Use the pin header labeled J5, base
address. The numbers above the jumpers correspond to the I/O address bits; bit 9 is the MSB and bit 0 is
the LSB. Only bits 9 – 4 are used for the base address decoding. The remaining 4 bits 3-0 are assumed
to be 0 for the base address. When a jumper is in, the corresponding base address bit is a 0, and when it
is out, the bit is a 1.
The default address is 300 Hex = 1 1 0 0 0 0 0 0 0 0, so 9 8 are out and 7 6 5 4 are in. Any address
above 100 Hex is a valid I/O address. However, there are many other circuits and boards sharing the I/O
space, so you should check the documentation for your other boards to avoid conflicts. Below are some
recommended I/O addresses for Ruby-MM-1612. Although the Base addresses can only be selected on
16-byte boundaries, Ruby-MM-1612 only uses the first 8 addresses.
