8920MUX Instruction Manual

Configuration

The 8920MUX provides 18 configuration functions across two banks of the
rotary switch positions (shown in

Table 6

). To make a configuration setting,

rotate the switch to the desired configuration parameter. The 16-position
rotary switch increments through 32 selection positions by addressing a
first and second bank of 16. When the switch is in the second bank, the 2nd
LED is illuminated. Move the paddle switch momentarily to either the up
or down position to make the desired selection

Refer also to

Table 5 on page 20
