Usually, forcing a new Ethernet negotiation is enough to solve the issue (e.g. by
unplugging and plugging again the Ethernet cable). A workaround for this issue is
implemented in R&S TSME6s firmware since version 05.08.10.00. This workaround
also requires an up-to-date software release (R&S ViCom 21.0 or newer, ROMES or
newer).
Problem: Unable to connect to R&S TSME6 when using a PCIe Network card
using a network chip from Realtek
Sometimes a PC is properly configured to communicate with R&S TSME6 and no con-
nection is possible. A possible reason is an issue with default drivers available in Win-
dows 10 for the network card not setting the MTU value correctly. Updating the driver
solves the issue.
Problem: Sporadic connection issues when using firmware 05.08.10.00 or newer
version
Sometimes the PC is not able to connect to R&S TSME6 (firmware 05.08.10.00). A
possible reason is an old software release which is not compatible with the implemen-
ted workaround starting from this firmware version. The workaround is available start-
ing from R&S ViCom 21.0 or ROMES 21.1.
This issue rarely happens on a system, the worst case to trigger it is to use a single
R&S TSME6 connected to PC using an unmanaged network switch. If compatibility
with an older software stack is mandatory, try one of the following solutions:
●
Connect PC directly to R&S TSME6. It drastically reduces the probability to trigger
this issue.
●
Connect a second active R&S TSME/TSME6 to the network switch.
Problem: Sporadic network issues
If there are sporadic network issues, disable the "Flow Control" in the network adapter
settings.
