Analog I/O connectors: Connectors J29 and J39
Connector J29 provides six analog I/O for Shield 0 and connector J36 provides six analog I/O for
Shield 1. The following table shows the pin mapping for connectors J29 and J39.
Power and voltage references: Connectors J26 and J35
Connector J26 provides power and voltage references for Shield 0 digital I/O. Connector J35 provides
power and voltage references for Shield 1 digital I/O. The following table shows the pin mapping for
Shield connectors J26 and J35.
Supplementary connectors J27 and J37
The supplementary connectors, J27 and J37, provide subsets of the signals on the main Shield
connectors. Connector J27 provides a subset of the Shield 0 signals and connector J37 provides a subset
of the Shield 1 signals. The following table shows the pin mapping for connectors J27 and J37.
