Jumper Settings
The expansion boards are connected to the MUA II Controller with
a modular cable. Up to 2 Expansion Base Boards can be populated
with expansion boards to provide additional inputs and outputs. The
expansion boards can be placed on the expansion base board in any
order; however, the jumpers on the Expansion Base Board must be set
correctly for proper operation. See Figure 6 for correct jumper settings
and jumper locations.
