This section describes the location and orientation of the Model
1140RC's configuration switches and jumpers, and provides detailed
instructions for all possible settings.
The Model 1140RC uses a combination of DIP switches and
jumpers that allow configuration to an extremely wide range of
applications. Designed around a mid-plane architecture, the Model
1140RC incorporates both front and rear cards. Configuration of both
may be necessary. The switches/jumpers are accessible when the
cards are removed from the rack chassis. Once configured, the Model
1140RC is designed to operate transparently, without need for frequent
re-configuration.
3.1 FRONT CARD CONFIGURATION
The Model 1140RC front card has two sets of eight switches (S1 &
S2), which are mounted on the PC board (Figure 1, below). These
configuration switches allow you to configure the Model 1140RC for a
wide range of applications. The ON/OFF orientation of the DIP
switches is shown in figure 2 (below).
