does my MK3 work?

I am trying to configure a MultiPlus using a MK3 but when I plug in the Cat5 cable into the MK3 I get the MultiPlus go into error mode and get 14 (Device cannot transmit). Using a HP computer with Windows10, I see the MK3 is on USB serial port COM3. My Multi firmware sticker says 2702481.VFD

MK3

I forgot to add this information, I inspected the RJ45 Jacks and none of the pins were bent. I ran a TDR on the cable, all 8 lines are fine, it is 7 ft long, straight through (pin 1 to 1, 2 to 2, .....8 to 8)

That is basically the same information as in my MultiPlus manual, error 14 is can not transmit. My current guess is Victron does not do MDI or MDI-X so I need to use a crossover cable. I ordered a actual Victron cable and should get that in the next few days and I’ll TDR that cable to know what type it is and try that.

Other related information, I can plug in the cable to the Multi and have no issues, it is when I plug the other end into the MK3 that I get the error.

It's a CAT5 straight UTP cable. Doesn't need to be from Victron, but quality wins over price.

Have you tried another cable, could be that, even though yours tested ok. Must be the full 8 wire, non crossover as Stefanie said.

Also do you have something else connected to the multi? When VE configure starts, it warns about disconnecting these.

Ote hrwise may be a faulty unit, that's a dealer job.

I ordered another cable, should get that today. The cable was tested with a cat5 cable tester though, it tests all 8 paths. Are you saying a crossover cable will not work? That would surprise me because when connecting like equipment you normally use a crossover cable.
