RAD-Comet 2

Operational Overview and Use Cases

The RAD-Comet 2 can be used as a media converter between 10BASE-T1S and either of the  other Ethernet physical layers available on the device. It can also serve as a media converter for  100/1000BASE-T1

10BASE-T1S  ⇔ 10/100/1000BASE-T

10BASE-T1S ⇔ 100BASE-T1

100/1000BASE-T ⇔ 100/1000BASE-T1 Media Conversion

Stand-Alone Gateway

Elaborate gateways can be implemented between any of the networks available on the RAD-Comet 2.

CAN/Ethernet Gateway

Payloads can be extracted from frames arriving on one network, placed into a different PDU structure  with a different header and sent to another network.

Examples of this utility include (but not limited to):

• Networking devices from different architectures for a proof-of-concept
• Networking devices during the transition from one vehicle architecture to the next
• Streaming select (or all) network traffic for logging and analysis

Ethernet/Ethernet Gateway

Frames can arrive on one Ethernet network and sent out to another network directly, or after changing anything in the header or payload.

This functionality can be used to realize many novel functions useful in vehicle testing.

For Example:

• Changing frame destination
• MAC Spoofing
• Layer 3/4 Address Translation
• Payload scaling
• Payload manipulation (Boundary testing, fault injection, penetration testing, etc.)

Simulation and Scripting

Using Vehicle Spy you can define transmit messages on any network with custom data and send them manually or on a schedule of your choosing. You can also write intelligent scripts that implement arbitrary logic and compile them into embedded scripts which can run within the device itself. This functionality allows you to create specialized test scenarios, and to simulate ECUs and gateways.

PHY Register access

In any mode, each PHY can be accessed by the embedded processor over MDIO in order to read and write configuration registers.
