The Subchannel is just a software code that is appended to each radio packet. It does
not affect the frequency hopping sequence like a Channel does. Use a Subchannel if
you need more than 15 Masters in the same coverage area and, therefore, all the Chan-
nels are used.
For example, you can use Channel 1, Subchannel 1 for Network A and Channel 1,
Subchannel 2 for Network B. The two networks will not communicate with one an-
other. They are, however, still sharing the 1.6 Mbps pipe since they are both using
Channel 1.
In order to establish communications, all communicating stations 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 fre-
quency or the frequency hop 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.
When the RangeLAN2 Access Point is configured as a Station, the First Master To
Sync To parameter names the Master with which this unit will synchronize. If this field
is filled in, there will be another choice, Second Master To Sync To. If the first Master
is unavailable to the RangeLAN2 Access Point, it will look to the second Master. Simi-
larly, if the second choice is filled in, a Third Master To Sync To field will be visible.
If no list is configured, the radio will continually look for the best Master. These param-
eters are case-sensitive.
The optional Master Name parameter specifies an alphanumeric name to simplify the
identification of each Master in your network.
If the 10BaseT Link Monitor is enabled and does not detect an Ethernet connection, the
Access Point will automatically switch from the configured Domain to the Error Do-
main, and any wireless clients will lose synchronization to it. This allows the wireless
clients to roam to other Access Points on the wired backbone that have maintained
Ethernet connectivity. By default, the Error Domain is set to 13. If your wireless net-
