The Topology view shows a diagram of the network’s wireless connections. Use this view to see whether all the radios are linked, and approve of the way the radios are linked. A radio that is not linked to a parent will show as a circle outlined by a flashing dashed red line. It may be near the bottom of the window. Scroll down to view all available radios. To change how radios link to the network, see Parent Link settings (page 82). Refer to Improve Signal Quality (page 66) for more information on overcoming poor connectivity.

If the radio is to be used in a hazardous location, the radio must be mounted in an enclosure approved for hazardous locations. The radio requires a separate cable connection to the SMA connector that leads to an internal antenna.

Connecting Antennas

 Each radio must have an antenna connected to the Main antenna port on the RLX2 radio; without an antenna for each radio, the network will not function if the radios are more than a few meters apart. You should always connect the number of antennas on Port A, PortA-PortC, or PortA-PortB-PortC, as indicated in the #antennas control. The network will not function without all antennas installed. All antennas for radios that communicate directly with each other should be mounted so they have the same antenna polarity. Antennas with N-jack connectors cab be mounted directly to the radio using an N-plug to N-plug adapter. Screw the antenna onto the antenna port connector until it is snug. For remote placement of antennas, an extension cable with N-plugs can be used. Because the antenna cable attenuates the RF signal, use an antenna cable length that is no longer than necessary to ensure optimum performance

Test the Network Installation Plan

 Test proposed installations before finalizing the installation. After the network and radios are configured:  Install the Master radio in its proposed permanent location  Cable the Configuration PC to the Master radio  Place the Remote radios in their proposed locations  Temporarily place each radio's antenna near its proposed mounting location. The temporary placement of the antenna can be by hand. However, one person must hold the antenna while the other person monitors the Remote radio's signal strength displayed on the Configuration PC.
