Figure 3 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.
Figure 3. TX3 devices connected to a combination ethernet TCP/IP
network with RS-485 subnetworks.
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.
Note: Normally, 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. However, if you want to connect to a
Touch Screen panel remotely over the Internet (for instance, to
