=== IGEPv2 EXPANSION ===

In order to test the CAN interface you can connect IGEPv2 EXPANSION to a CAN device or network or to another IGEPv2 EXPANSION. <section begin=IGEPv2 EXPANSION />You have to connect the two boards like this:<br>

In the last case, you have to connect the two boards like this:<br>   Board IGEPv2 1 Board IGEPv2 2
