Description

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.

Features:

  • Easily connect and power multiple AEMnet CAN devices from a central docking station!
  • Four integrated 4-way DTM-style housings provide reliable AEMnet CAN connections
  • Daisy chain two Hubs to connect six AEMnet Devices
  • Compact enclosure - 3.45” (87.63mm) Long x 1.18” (29.85mm) Tall
  • Safe for engine bay mounting – IP67-rated enclosure
  • Mounting hardware included (two 4-40 x 7/8” flat head screws, two 4-40 x 0.375” washers and two 4-4 x 9/64” Nylock nuts)

Specifications

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:

AEMnet Device Configuration
30-71XX Infinity ECU Hardware enabled by default on CAN A (AEMnet)
Series 2 EMS Hardware enabled by default (AEMnet)
30-56XX and 30-57XX CD Carbon Digital Dash Displays Software selectable, enabled by default
30-25XX AQ-1 Data Loggers Included, non configurable
30-2226 6 Channel CAN Sensor Module No resistor
30-2224 22 Channel CAN Sensor Module Jumper Selectable
30-2224 8 Channel K-Type EGT CAN Module No resistor
30-03XX X-Series Gauges No resistor
30-49XX Wideband Failsafe Gauges No resistor

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

DTM 4-pin Termination Resistor PN Description
35-3440-F AEMnet Termination Plug, Female
35-3440-M AEMnet Termination Plug, Male
