Figure 23 Lobby Control Units Using Both Ethernet And - Mircom TX3 Series Installation And Operation Manual

Figure 23 shows a configuration with TX3 devices connected on both an ethernet
TCP/IP network and on RS-485 subnetworks. Devices connected to a Master
Node's RS-485 subnetwork are Slave Nodes to the Master Node. Each RS-485
subnetwork can have up to 63 devices connected to it; you can still have more
than 63 Master Nodes connected to the ethernet network.
Ethernet Network
Figure 23. Lobby control units using both ethernet and RS-485 networks
If you connect to the ethernet TCP/IP network with the TX3 Configurator, you
can configure any of the nodes in this configuration. If you connect directly to a
device using USB, a modem, or a COM port, you will only be able to configure
devices that are on the same RS-485 subnetwork as that device.

RS-485 Subnetwork
There can only be one Master Node on an RS-485 subnetwork. That
is, you cannot connect one RS-485 subnetwork to another RS-485
subnetwork.
