2. NETWORK INSTALLATION
2.1 Items Needed
To install a network, begin with the Supervisor and at least one Node that is within radio range
of the Supervisor.
2.2 Channel Configuration
Channels allow multiple networks to coexist in the same area. All devices are set to
communicate on channel one from the factory and do not need to be altered if operating a single
network in a given area. However, if multiple networks are within radio of one another then the
devices of each network must be set to different channels.
To set the channel on a Node or Supervisor:
1) Open the device by unscrewing the four captive screws on the front of the enclosure. Make
sure that no dirt, water or other contaminants are allowed to enter the enclosure.
2) Set the channel select dipswitch (shown in Figure 6) to any of the 12 valid positions listed in
Table 1.
3)
Devices will only communicate with others that have been set to the same channel.
To prevent erratic behavior, there can be only one Supervisor on a particular channel. A
Supervisor with the same channel setting cannot be within radio range of any of the units of
another network.
