Botblox Ethernet Leads

BotBlox Hardware

Hello there,

One of my business associates is having intermittent issues with Ethernet bandwidth. I traced one of the problems to a brand new and previously unused BotBlox Picoblade to RJ45 Ethernet lead. The connection would drop out when the wires at the RJ45 end were moved around.

Can you advise if you have seen any similar problems

and

Can you advise the size parameters of the in house wire you use please? ie. strand size, number of strands and outside diameter?

We are looking at optimising the connectors we use to reterminate faulty cables.

Thanks

It’s pretty rare, we probably have over a million cables out there in the wild and we don’t often get reports of cable fails, can you share a little more information

  1. Have you tried a different cable?
  2. What are you plugging into on the RJ-45 side?
  3. Have you tried a standard RJ-45 to RJ-45 cable into your device to see if there’s an issue with the RJ-45 jack?
  4. What BotBlox board are you using? Have you tried swapping the board?
  5. How do you see the connection drop? Do you see the link go down?

Hello Josh,

Thanks for the information :slightly_smiling_face:

I have made an adapter by soldering two picoblade sockets together 1to8, 8 to1 (reversed) and used the faulty cable and another new cable as a pseudo Ethernet cable. A test device on one end that responds to ping requests, laptop on the other end ping -t Moving the faulty cable at the RJ45 end causes intermittent general ping failure. Replacing the faulty cable with another cable gives rock solid results, put it back, problem returns. There is no doubt in my mind, the cable is faulty at the RJ45 end.

Cheers

Your forum doesn’t seem to like arrows used as brackets (probably think they are tags?) and has removed them and the text between them so I’ll try another approach

“laptop on the other end ping -t [test device IP].”

Got it, ok thanks for clarifying that. Assuming this is a fresh cable out the box, this does sound like a faulty crimp on the RJ-45 side. It does happen very occasionally.

Happy to send out some replacements for the trouble. Ping us at info@botblox.org
