The Model 1094A is equipped with three sets of eight DIP switch-
es, which allow configuration of the unit for a wide variety of applica-
tions. This section describes switch locations and explains all possible
configurations.
3.1 CONFIGURING THE HARDWARE DIP SWITCHES
The 24 external switches are grouped into three eight-switch sets,
and are externally accessible from the underside of the Model 1094A
(See Figure 1).
The three sets of DIP switches on the underside of the Model
1094A will be referred to as S1, S2, and S3. As Figure 2 shows, the
orientation of all DIP switches is the same with respect to “ON” and
“OFF” positions.
