??Range - The operative range of your WLAN or Wireless Link in the drop down list. This parameter affects the acknowledge delay time which needs to be increased in long links. The default value is up to
5 km.
??Channel - Channel selection varies, depending on the type of unit.
For DWL-1800B units, select the channel that the unit will use by selecting a value (range: 1-13, depending on your regulatory domain) from the Channel drop down menu. Refer to Table 4 on page 32 for the list of corresponding frequencies.
For DWL-1800R units, there are two channel setting options: if you select the Fixed Channel option by clicking the appropriate radio button, then the DWL-1800R will search for the DWL-1800B unit on the selected channel (from the Channel pull down field) and synchronize with it. The channel you select must match the channel selected in the DWL-1800B unit at the other end of the link.
If you select the Scanning Mode option (by selecting the appropriate radio button), you can specify preferred channels by clicking one or more of the buttons displayed at the bottom of the window. In this mode, the DWL-1800R will first search for the DWL-1800B unit on the channel you select in the Channel pull down field and synchronize with it if the link is established. If the DWL-1800R does not find the DWL-1800B, it will scan and search for one of the preferred channel frequencies you selected. If it does not find the DWL-1800B on any of the preferred channels, it will continue to scan until it finds the DWL-1800B on one of the channels permitted according to the regulatory domain.
Table 3 describes the channels used in each regulatory domain, the default channel, the maximum output power and the default output power.
