Very good, the results have improved markedly. 5 and 8 Mbps are now possible and reliable even using the IPEK-003000 cable.
The secret seems to be dividing the "nominal" bits into more quanta. With a nominal TSEG1 < 10 (80% sample point), the receiver tends to detect quite few stuff errors. However ...

I downloaded the latest PCANView 5.0.1.822 using your link. However, I do not see the "CiA 1301" option in the bit rate preset.

Thx,

Hi Marvin,

I have turned off everything I can (including the lights) except the PCANView computer. Still no joy.

Hi Marvin,

My apologies for breaking any rules of this forum.

I appreciate all your support on this Marvin.

I performed the measurements as discussed in the link https://forum.peak-system.com/viewtopic.php?f=120&t=52 on both adapters and all measurements were 2.47V +/- 0.01V. So, well within the ...

Hi Marvin,

So I ordered and received the IPEK-003000 cable from Phytec ($25 + the same in shipping!) and it's not performing any better than my ethernet pair without a common ground: I cannot reliably transmit a periodic 8-byte message at 4 Mb/s or higher.

Thx,

Pete

Hi Marvin,

I have attached some pictures.

Hi Marvin,

I chopped the cable down to ~30 cm, activated the terminators in the PCAN USB dongles and removed the external terminators. 4 Mbps is ok, but 6 Mbps is not reliable. I would love to see Peak's test setup for 12 Mbps. I understand from the website that the FD dongles use the NXP TJA1044GT ...

Hi Marv,

I am sure about the cable as it's marked on the jacket and I cut the RJ connectors off both ends and soldered D-9 connectors. The terminators are Peak-System MiniTerm 120 ohm.

Thx,

I am trying to verify the operation of CAN FD using the following setup:

( PCAN-USB FD ) + ( 120 ohm Terminator ) + ( 2 meters 1 pair TIA-568A cable ) + ( 120 ohm Terminator ) + ( PCAN-USB Pro FD Channel 1 )

Both PCANs are running v3.2.0 firmware.
Both PCANs are connected to the same PC via high ...
