Our designs make frequent use of standard 4 pair gigabit Ethernet via Moog slip rings made to handle same. Of course, SPE GigE involves higher frequencies than 4 pair signaling. Have the SPEBlox GigE boards been shown to work through slip rings? The TI chips involved obviously have remarkable signal processing and equalization but impedance discontinuities and possible cross channel interference may be beyond them. But if they do work, they would provide a terrific asset for designs we are working on.
If such tests have not been done, we are interested in ordering two so we can do so. Hooray for iperf3!
Sorry this ended up in General, not Hardware category!
Hi Jim
We haven’t actually tested that. If you can test this for us and provide details of the wiring and slip rings you will use, we’ll happily send you a pair for free. I’ll email you.
Hi Josh,
We have completed some initial testing with the SPEBlox over a slip ring and are generally impressed with the reliability and bandwidth capabilities. See the test setup and results below:
One concern we had was the robustness of the screw terminal in aviation environments. Are there any plans to conduct mil spec testing? specifically vibration? We would also be interested in ordering Rev E if the only change was the connector (pico)?
Glad to hear the testing went well.
We can still make the previous version, but the cost is higher and there is an MoQ. I’ve reached out via email with that information. You might consider…
-
De-solder the screw terminals and solder the wires directly to the board. This is more work, but mechanically very robust.
-
Secure the existing screw-terminal wires with epoxy or similar. Not as elegant, but it adds good strain relief without modifying the board.
We have conducted shock and vibe tests on this version, below is a link to the full results.
@josh-elijah l get a 404 error when i click the link?
Odd, seems the forum is changing the link I post, I posted it there now.
For future reference, environmental test results for all our hardware (Along with all other documentation) can be found by going to the “Technical Documentation” tab on the product page.
We’re transparent and public with all our test data.
Perfect! must’ve missed it in the Tech docs link. Thanks for all the support, we will keep you guys in the loop for further integration.
Pleasure! Keep us posted!
