AEMnet CONNECTIONS
AEMnet
AEMnet is an open architecture software and hardware interface based on the CAN 2.0
specification, which provides the ability for multiple enabled devices to easily
communicate with each other through a single cable. The hardware connection is made
through a Deutsch 4P DTM connector and contains 12 volt switched power and ground
(2A max) as well as the CAN data lines. Devices connected to the AEMnet transmit
data through this one connection and most of these devices receive power from this
same connection as well.
Connection via AEMnet/CAN is recommended as it is the easiest connection (only
needs one connection) and it eliminates the possibility of any analog voltage
losses/offsets commonly associated with analog inputs/outputs.
