What will cause Nion node TX and RX error in NWare interface?
For some reasons, I found sometimes TX and RX LED flash, at that moment CobraNet audio will be spasmodically. What canI do now?
Thanks!!!

Weidong,
Have you tried using CobraNet Discovery (Disco) to look at the error codes in the CM-1?  If there is a network issue, this may help you figure it out.

Thanks Joe, I used CobraNet Discovery and I found error code in the CobraNet module, Ivor pasted those error codes in this forum, let me show you.
2091- Buffer exhausted. Network is too busy for the device to transmit its data.
3997696 - Rx quiet. Dropped packets
61 - Same as 3997696
2228226 - beat packet flood
4130,4136 - Flash Failure

Anything else, non-Cobranet stuff, on this network?

Only CobraNet units, without other non-CobraNet stuff.
