In order to establish communication, all Stations and the Master must be configured with the same Domain number. Radios on different Domains cannot communicate with each other. The Domain is a software filter which does not affect the actual radio frequency or the frequency hopping sequence.

You may want to set everyone on your network to the same Domain. For larger wireless networks, use the Domain to establish roaming subnetworks throughout your building. For example, the Engineering Department may use Domain 2, and the Sales Department may use Domain 5. Then engineers can only roam within the geographical area mapped out by RangeLAN2 Access Points with a Domain setting of 2.

The Domain is a number between 0 and 15. Choose “U” for Use Switch in order to use the number specified by the Domain rotary switch. The default setting is the rotary Domain switch which shipped from the factory set to Domain 0.

Note that while the rotary Domain switch allows the user to set the Ethernet Adapter to operate on a Domain number between 0 and 9, the software configuration menu allows the user to set the Domain to a number between 0 and 15. If you want to use a Domain number between 10 and 15, you must configure this parameter within the software configuration menu.

Each Master can select one of 15 Channels to establish commu- nication with its Stations. Each Channel number sets a unique frequency hopping sequence allowing for multiple subnetworks with higher data rate transmission capability in the same air space. You may think of the Channel as a pipe. In order to communicate, radios must be on the same Channel and there must be one (and only one) Master that provides the timing for that Channel.
