Figure 2 shows a network with two Card Access Controllers connected to an RS-
485 network. The Card Access System can have up to 63 Card Access Controllers
networked together. If you connect to any device on the RS-485 network (using
USB, a modem, or a COM port), you can also connect to and configure any other
device on the RS-485 network using the TX3 Configurator software.

Figure 3 shows a configuration with Card Access Controllers 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.
