any device on the RS-485 network (using USB, a modem, or the COM port), you
can also connect to and configure any other device on the RS-485 network using
the TX3 Configurator.
Figure 23. TX3 devices on an RS-485 network.
Figure 24 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.

Notes: In order for a panel to connect to an Ethernet TCP/IP network:
• it must be IP capable. Panels that are IP capable usually
have “-A” or “-B” or “-C” at the end of their model names.
