Using Multiple PowerLabs

Multiple PowerLab C units can be connected in one of two ways:
1. Daisy Chained: The 'Computer' port of the second PowerLab C is connected to
one of the downstream facing ports on the first PowerLab C. This allows the
second PowerLab to be powered by the first, allows full use of the PowerLab
Event Link (PEL) between devices but comes at the cost of using one of the
available downstream facing ports on the first PowerLab.
2. Connect both PowerLabs to the host computer: This maximizes the number of
downstream facing ports for other C Series devices but comes at the cost of
not allowing PEL communications between C Series devices connected to the
diff erent PowerLabs.
