Figure 2 shows a configuration with TX3 devices connected to an Ethernet TCP/
IP network. This configuration removes the 63 device limitation that you have on
an RS-485 network. The devices connected to an Ethernet TCP/IP network are
called Master Nodes. If you connect to the TCP/IP network with the TX3
Configurator, you can connect to and configure any of the Master Nodes on the
Ethernet TCP/IP network. If you connect directly to one of the Master Nodes
using USB, a modem, or a COM port, you will be able to configure that device
but not any other device.
