Attachment of the RangeLAN2 Serial Adapter Antenna
4. Each RangeLAN2 791x Serial Adapter is preconfigured to use Domain 0. If you have multiple pairs of Serial Adapters and each pair consists of one Master and one Station, set each pair to a unique Domain number. Using the Domain rotary switch on the underside of the RangeLAN2 Serial Adapter, set each pair to a unique Domain number from 0-8 to ensure minimal interfer- ence. If you decide to use Domain 8, refer to Chapter 5 for information concerning this switch setting’s role in the Pairing Domain communication feature

Figure 6 above shows a simple configuration of this topology. Desktop 1 is on the same network as a RangeLAN2 Access Point. Serial Adapters 1 and 2 are configured as Stations and are synchronized to the Access Point, which is configured as a Master. Desktop 1 is running a custom-made application written in a programming interface, such as Windows Sockets, which uses TCP/IP to communicate with either or both Serial Adapters

In order to establish communications, 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

For example, you can use Channel 1, Subchannel 1 for Adapter Pair A and Channel 1, Subchannel 2 for Adapter Pair B. The two pairs will not communicate with one another. However, they are still sharing the 1.6 Mbps pipe since they are both using Channel

There is no inactivity timeout set by default, but you may change this to any interval of 10 seconds. This parameter is visible only when the Serial Adapter is set as a Station. A Master unit does not have a sleep mode
You may choose to disable a Serial Adapter’s ability to roam with the Roaming Enabled parameter. This feature is enabled by default however, if you want a RangeLAN2 Serial Adapter to communicate with one and only one other RangeLAN2 product, you may disable this feature

cate with the wired infrastructure, it will be necessary to change the default address to one which is on the same subnet as the wired stations so that IP packets are routed correctly. You can override the default address using the IP Address option in the configuration menu. This parameter will not change unit the Serial Adapter is reset
