How Do I Use One CAN Interface to Communicate and Monitor Two Independent CAN Buses?
Rena Ayeras

Question from the Customer:

I have one Komodo CAN Duo Interface. How do I use it to monitor two independent CAN buses?

Response from Technical Support:

Thanks for your question!  This is easy to do with the Komodo CAN Duo Interface.  You can use two instances of the Komodo GUI Software or the Data Center Software (or one of each) with channel A and channel B of the Komodo CAN Duo Interface to monitor two CAN buses separately. (The Komodo CAN Solo Interface provides only one channel.)

The Komodo CAN Duo Interface has two independent, customizable CAN channels as well as eight configurable GPIOs. The Komodo CAN Duo interface also has two virtual USB ports (via a single physical USB port). These virtual USB ports make it possible to communicate and monitor via two software instances, and thus two independent CAN buses.

Here’s a preview of how:

With the Data Center Software, you can select the bus to be monitored in the Device Settings as shown below.

With the Komodo GUI, you can select bus in the Connect window as shown below.
