AEM’s 4 Port AEMnet CAN Hub is the perfect solution for connecting multiple AEMnet CAN bus-enabled devices together. This convenient Module provides a central docking station for four AEMnet cables via 4-way DTM-style housings and can provide power to all of the connected devices on the Hub through a single port (3A max current capacity – NOT for use to power UEGO sensor heaters). Users can daisy-chain two 4 Port AEMnet CAN Hubs together for a total of 6 connected devices.

AEMnet buses must be properly terminated using termination resistors on each end of the port (120 Ohms each, see Specs tab for AEM Devices with termination resistors). AEM offers DTM-style 4-pin termination plugs that simplify this process if you have a device that does not have an integrated or selectable termination resistor.

The 4 Port CAN hub is IP67-rated and can be installed in the engine compartment. Mounting hardware and instructions are included.

POWERING DEVICES THROUGH THE 4 PORT AEMNET CAN HUB:

All 4 Port AEMnet Hub ports have the same pinout, so power and ground is only necessary on one port when powering devices through the Hub. IMPORTANT: The Hub has a max current capacity of 3A (do NOT attempt to distribute UEGO sensor heater power through the Hub).

PROPER BUS TERMINATION:

AEMnet buses must be properly terminated for proper operation. The termination resistors are 120 Ohms each and must be located at the physical ends of the bus wires (two total). Please refer below for Termination Resistor availability by AEMnet-enabled device:

Termination resistors are available to simplify bus termination if your devices do not have a resistor:
