Control Systems. The RAD-Star is an inexpensive but powerful tool that facilitates the design, development, analysis and troubleshooting of Automotive Ethernet (AE) networks. The RAD-Star is primarily used as an active tap inserted between a pair of AE devices. The RAD-Star’s hardware passes all traffic between these devices with virtually no added latency, while sending a timestamped copy of each message to a standard Ethernet device (such as a laptop PC) for monitoring. - Page 5 PC to Figure 1: Using the RAD-Star as an Active Tap. On the left, a standard connection between an Automotive Ethernet switch and a single ECU. (Other ECUs connected to the switch are not shown.) On the right, the network that results after inserting the RAD-Star as an active tap.
- Page 6 PC to Device Figure 2: Using the RAD-Star as a Media Converter. Connecting just one Automotive Ethernet device to the RAD-Star creates a simpler network that allows a PC or other standard Ethernet hardware to interact with it. Timestamping and Frame Wrapping The RAD-Star records the time that each message is received on one of its BroadR-Reach ports.

Conventional Ethernet Side. Automotive Ethernet Side This panel of the RAD-Star (Figure 4) contains a pair of Molex Mini50 jacks. While there is no standardized Automotive Ethernet connector type, the Mini50 is used by many BroadR-Reach / 100BASE-T1 devices, including Broadcom switches and other Intrepid AE hardware. - Page 8 RAD-Star User’s Guide Figure 4: RAD-Star Automotive Ethernet Side. The Mini50 BroadR-Reach connector on the left is internally configured as a master device, while the one on the right is configured as slave. Each has a combination link/activity LED. Note: One of the ways that BroadR-Reach delivers high per-...

• Activity LED (Above Right): Flashes when traffic passes in either direction over the attached Ethernet cable. When the RAD-Star is used as an active tap, both ports will have their link LEDs on, and their activity LEDs will flash at a rate proportional to the amount of data being transferred. Using the RAD-Star as a media converter will result in the LEDs being lit on the port with the attached cable, while those on the other port will remain dark. - Page 10 Requirements to Use the RAD-Star as a Media Converter If you are using the RAD-Star as a media converter, the following changes apply to the list above: • Only one Automotive Ethernet device is needed, rather than two.

No Connect Table 1: RAD-Star BroadR-Reach Mini50 Jack Pinout. Figure 6: RAD-Star BroadR-Reach Mini50 Jack. Pins are numbered 1 to 4 from left to right looking at the jack, as shown. Power Cable The RAD-Star is powered through its DB-9 port (also called a DE-9), which is the standard connector used in the automotive industry for the CAN bus. -

The instructions that follow assume that any necessary cables have already been fabricated or modified as described in the previous section. Figure 8 shows you at a glance how to set up the cables to use the RAD-Star as an active tap. Version 1.2 - June 1, 2016... - Page 13 When connecting your Automotive Ethernet devices, attach the ECU or switch port configured internally as a master to the BR SLAVE port of the RAD-Star, and the device configured as slave to the BR MSTR port. Note that some AE devices can operate as master or slave and can thus be connected to either port.
- Page 14 Connect Ethernet Cables to Ethernet Switch: Insert the other ends of the cables you just connected to the RAD-Star and PC into open jacks in your Ethernet switch (or hub). (For most devices, the exact choice of ports on the switch/hub does not matter.) Version 1.2 - June 1, 2016...

(BroadR-Reach or conventional) and that the device is powered on and operating. If the RAD-Star is connected to a powered device and still has no LEDs lit, this usually means that the RAD-Star itself is not receiving power. Try the following: •... - Page 20 Reach devices and cables vary, this issue may be application-dependent, but please try the following: • Ensure that a connection from the RAD-Star’s BR MSTR port goes to an ECU or BroadR-Reach switch port configured as a slave device; similarly, any connection from the BR SLAVE port should go to an ECU or switch port configured as a master.
- Page 21 Reach device. Check the activity LED of the associated conventional Ethernet port (MASTER for BR MSTR, SLAVE for BR SLAVE) to see if the RAD-Star is retransmitting copies of the received frames correctly. If the MASTER or SLAVE conventional Ethernet LED is not flashing, then there is a problem with the link to your PC or Ethernet switch.

Page 23: Reference: Frame Wrapping And Wrapper Format
• Email: icsaustralia@intrepidcs.com Reference: Frame Wrapping and Wrapper Format In the overview (Section 3) we mentioned that the RAD-Star encloses each message received on its BroadR-Reach ports in a special wrapper frame before it is retransmitted to the conventional Ethernet network. The wrapper allows additional timestamp information to be sent with the message, enables the FCS field of the original frame to be captured, and ensures that error frames are not discarded. - Page 24 RAD-Star. The RAD-Star will encapsulate incoming messages in a single wrapped frame if they are up to 1,498 bytes in length. If the incoming message is longer, it is split into two pieces: the first carries the first 760 bytes of the original message (including its header) and the second carries the remaining bytes (including its footer).
- Page 25 • Last Flag: Set to 1 for the last (or only) part of a complete message; 0 otherwise. • Identifier: A number generated by the RAD-Star and placed in both pieces of a split frame to aid in reassembly by the receiving device.
- Page 26 • First Flag = 0 / Last Flag = 1: Second piece of a split message. • First Flag = 1 / Last Flag = 1: Complete, unsplit message. Version 1.2 - June 1, 2016 © 2015-2016 Intrepid Control Systems, Inc.
