Rotary Switch Configuration
A rotary switch on the CB-602I board makes it easy to set the appropriate signals, particularly
when installing multiple PC/104-Plus modules in the same unit. The rotary switch, which looks
like a clock, provides a bi-directional path with no signal propagation delay. The first module on
the stack should be set to CLK0, the second to CLK1, etc., to eliminate clock skew between
modules.
The module stack order is shown below.
