RAD-Galaxy 2

12-Port 1000BASE-T1 Active Tap and Gateway for Automotive Ethernet with CAN FD

Your Go-To Tool for Software Defined Vehicles and Zonal Networks Testing

Intrepid’s RAD-Galaxy 2 is a multi-purpose Ethernet Active Tap and Gateway for Automotive Ethernet. It has 12x 100/1000BASE-T1 PHYs, allowing it to tap 6 links between ECUs and/or switch ports for monitoring traffic between devices. The ports can also be used independently to connect up to 12 devices to a PC for simulation, testing, parallel ECU flashing. In addition to its Automotive Ethernet capabilities, it offers 8x CAN FD channels, DoIP/SoAD support and 1x 10GBASE-T port.

Active Tap Configuration

One use of the RAD-Galaxy 2 is to act as an active tap with 6x 1000BASE-T1 taps, transparently tapping between devices. These can be any combination of six ECU-to-switch or ECU-to-ECU links.The traffic from each device on a tapped link is forwarded to its partner, ensuring seamless operation of the network. Copies of all messages/streams are also aggregated and sent to the PC over the RAD-Galaxy’s 10G Ethernet link, where they can be analyzed using Vehicle Spy software.

Independent Ports Mode

The Rad-Galaxy 2 can be used to connect up to 12x 100/1000BASE-T devices to a computer. This is helpful for a number of use cases such as simulation, testing, diagnostics, and Parallel ECU flashing. In addition, any of the Ethernet ports can be bridged internally allowing media conversion between BASE-T and BASE-T1 devices.

Central Gateway Testing

The RAD-Galaxy 2 is uniquely configured to test central gateways. Connect to the “clean” and “dirty” side of the central gateway with four Ethernet ports, as well as the 8x CAN FD networks. All data is synchronized with better than 10 ns accuracy.

Automotive Ethernet PHY Testing

RAD-Galaxy 2’s user-friendly and powerful design allows you to validate and debug physical layer/PHY issues. The RAD-Galaxy 2 provides PHY-level information including signal quality measurement, master/slave or negotiation modes, and other status available from the PHY.
