Rugged 7-Port Managed Switch for Automotive Ethernet (100/1000BASE-T1)

Intrepid’s RAD-Jupiter is a rugged 7-port managed switch designed specifically for bench and vehicle network development. In addition to its Ethernet functionality, it integrates many of the key CAN, LIN, and scripting features found in our ValueCAN 4 family of tools.


  • Marvell 88Q5050 Switch with Integrated 100BASET1 PHYs
  • One channel of 1000BASET1
  • 7-port switch with selectable Gigabit PHY’s
  • Embedded AVB/TSN protocol stack
  • Embedded processor for scripting and embedded C applications
  • Intrepid Security Module supporting cybersecurity applications
  • 8x dual purpose LEDs for network status and device configuration
  • Rugged aluminum case with shock-absorbing boots
  • Flexible power options (DB9/USB-C/barrel-jack)
  • Field-upgradeable flash firmware

Network Specifications:

  • 7 port switch:
    – 5x 100BASE-T1 ports
    – 1x 1000BASE-T or 1000BASE-T1 port
    – 1x 1000BASE-T or USB/GigE bridge
  • 2x CAN FD channels with programmable termination
  • 1x LIN channel

Switch Protocols and Features

    • 802.1Qav – Forwarding and Queuing for Time-Sensitive Streams (FQTSS)
    • 802.1AS – Generalized Precision Timing Protocol (gPTP)
      (Time Aware Shaping in future firmware release)
    • Static Stream Reservation
  • IEEE 802.1Q tag support with 4096 VLANs
  • Port mirroring
  • Ingress policing and rate limiting
  • Ternary Content Addressable Memory (TCAM)

AVB/TSN Use Cases

  • AVB compliant bridge supporting static streams
  • AVB/TSN network sensitivity analysis (Insert latency or switch hops; Add additional ECU’s for more BE or stream traffic.)

Media Converter

The BASEs are covered! 100BASE-T1, 1000BASE-T1, 1000BASE-T, and a USB/GigE Bridge. A media converter is as simple as setting up bidirectional port forwarding between any 2 ports. The RAD-Jupiter can be configured for 2x 100BASE-T1 converters or 1x 1000BASE-T1 converter without losing the use of the remaining ports of the switch!

Gateway Applications
In addition to providing a network interface to your PC, the embedded processor in the RAD-Jupiter can be programmed to run real-time applications such as network gateways. Applications can be programmed in Vehicle Spy’s Function Blocks or in C Code which is easily compiled to run on the embedded processor.
Vehicle Spy Ethernet Applications
While RAD-Jupiter does not function as an Automotive Ethernet Active Tap, this does not prevent it from taking advantage of some of Vehicle Spy’s many Ethernet applications.
