The gaugeART CAN Gauge includes a user-configurable 120 ohm terminating resistor jumper. The resistor is enabled when the jumper is in place.- CAN networks require a 120 ohm resistor on the ends of the network – one at the ECU, and one on the last device in the network (see the image on the next page for an example). Leave the terminating resistor jumper in place if the CAN Gauge is the last device in the chain of CAN devices. Remove the jumper if there are already terminating resistors at the ends of the network (see the next page for an example).
- Having too many or not enough resistors can cause the gauge or other devices to malfunction.
- Add a 120 ohm resistor to your ECU if required. Consult your ECU’s user manual if your ECU is not listed below.ECUs that do not require 120 ohm resistor:
AEM Infinity, AEM EMS Series 2, Haltech, Link, ProEFI (if built into harness).ECUs that require a 120 ohm resistor to be added:
Hondata KPRO 4
Example of two CAN networks – one 120 ohm resistor must be on the ends of the network. Devices between the ends do not need a resistor.
