3.9 2-Channel Configuration

Two mono EVMs can be interconnected using J2 and J6 headers as shown in Figure 3-8. Place the EVMs side by side and connect J6 from the first EVM to J2 on the second EVM.

CAUTION: When 2 EVMs are interconnected, both EVMs must be set to the same mode, that is, either both EVMs are in Hardware mode or both EVMs are in Software mode. Mixed configuration is not supported. Use the same jumper settings for both EVMs.
CAUTION: Make sure to short J54 jumper on the secondary EVM, ie. the EVM that is not connected to the AC-MB controller board.
CAUTION: The power supplies used on the main EVM can be connected to the secondary EVM using the banana connectors.
