An X indicates a jumper is to be installed. An (X) indicates the jumper
is optional, depending on whether access to the analog bus is
required. A blank indicates no jumper is to be installed.

Analog Bus
In two of the above configurations, the 1260-37
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 achieve alone. This is accomplished by providing
access to a 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.
