3.2 IDENTIFICATION AND CONFIGURATION REGISTERS
3.2.1 Setting Multiplexer Size
Figure 4 shows the two jumper positions for the M220. When in position A (jumper not
connecting one row of pins), the module is configured as a dual 8-to-1 multiplexer. When in
position B (jumper connecting all pins), the module is configured as a single 16-to-1 multiplexer.
The M220 leaves the factory with the jumper placed in position A (dual 8-to-1 multiplexer). If
you need to change this jumper position, it must be done before installing the M-Module onto the
carrier.
