Scanner/Multiplexer circuit may be configured to access the analog
bus (refer to Figure 3-1). The analog bus allows expansion for the
configuration of larger scanner/multiplexers than the module may

common bus channel which may be daisy chained to other
multiplexer modules via the front panel
To connect the module to the analog bus, install jumpers W2A and
W2B on the motherboard PCB.
