Typical Arcnet network topology

Most of Arcnet network configure as a star topology. It is the most efficient and reliable configuration. Each computer with an arcnet card is attached to an arcnet hub. In a star topology, you do not need to use a 93 ohm terminator at the end of your cable connection. Below is a typical star topology setup.

On the other hand, if you are using a Bus topology setup, you are required to use a 93 ohm terminator at both side of the coaxial cable run. Without installing the proper terminator, you might encounter communication errors between arcnet devices. Below is diagram for a typical Bus topology setup.

Our 8 port arcnet hub works with most of arcnet card available on the market. Even if you are using QNX v2.0 8 bit arcnet card, our 8 port arcnet hub is 100% hardware and software compatible.
