[Arcnet] Question about CIRCLINK product.

[liubo]

    I am so surprised that so many people give their hands to me.Thanks a lot!

    I use ARCNET for several years.I use DC coupled 485,5 nodes,it is very good.But only use it in the cabinet.Today I need the network length reaches 150 meters or even more and under the noisy enviroment(Maybe use it in a train).I know that if there is much noise,ARCNET may often reconfig(I use COM20020 at 2.5Mbps) and reconfiguration will take a long time,so the communication between ARCNET nodes will be delayed.Can ARCNET say that the transmission delay will be decided under this circumstance?ARCNET is a mature product,I don't beleive that SMSC never think about this before they put ARCNET products to the market.Does anybody want to say something about this?
    Somebody recommand me that maybe I can use CIRCLINK protocol product,such as TMC27003.It seems that SMSC improve the protocol of COM20020.Can you give me any advice?Where can I buy it?(I am in Beijing ,China.)
