CONVIA ENABLE WALKERFLEX SYSTEM INSTALLATION (continued)
Network Hubs
The Network Hub module makes up the
backbone or Main Bus of the network. Multiple
Network Hubs can be configured to increase the
size of the network or to increase the number of
available ports in an installation location. Up to 50
Network Hubs can be connected on a single
network with a patch cable length of up to 2000
feet. Refer to the ConviaNet Design Guide for
more information.

Step 3: Connect Wiremold Convia Enabled pre-terminated
RJ11 cables between the Network Hubs. Install
Communication Loop Closures into RJ11 ports at the
beginning and end of the network run (Main Bus). Step 4: Install Wiremold Convia Enabled pre-terminated
RJ45 cables between the Network Hubs and the
Relay Dimmers, Power Modules, Sims, Switches,
and Scene Controllers.

NOTE: To ensure proper network functioning, Communication
Loop Closures need to be installed into the beginning
and end of the Main Bus of the network. If there is
only one Network Hub in the installation, then
Communication Loop Closures must be installed in
both RJ11 ports on the Network Hub.
