4.3. Expansion Connections
iBoot-G2+ has two Expansion Ports, Exp1 and Exp2 for connection to iBoot-Exp, or for use as General
Purpose Inputs and Outputs (GPIO). Mode settings on the iBoot-G2+ determine how the expansion ports
function.
Connections to the iBoot-Exp are made using screw terminal blocks. The screw terminal blocks are on
removable connectors for easy cable fabrication.
Make sure screw terminals are tightened securely and that there are no loose strands of cable, or excessive
stripped wires.
