For connect SSV104 to PC with network card RJ45, I need a transceiver AUI/RJ45 active

I am sorry but Joerg is right. The problem is that the AUI/RJ45 Transceiver you have is only connectable to the Uplink of the SSV 104. So if you connect the PC there it will work but be aware, you have to activate the Uplink and you will have to be aware that if the PC drops out, the complete Hub is down!

The only really working solution is a ELM. The 9 pin Sub D is signal compatible to the RJ45 signal. The AUI MAU Interface of the ELM can be directly connected to the SSV 104 DTE interface.

The Cable Pin out of the AUI Cable can be found in the Internet, Siemens calls these Cables 727-1 but actually they are called "Drop Cable". Check Google for it.

The Cabling for the ELM 9 pin Sub D to RJ45 you can check the Manual

I hope this could help a bit.

Best regards
