Figure 4 shows a Card Access System using an Ethernet network with RS-485
subnetworks. The Card Access Controllers connecting to a Master Node's
RS-485 subnetwork are Slave Nodes to the Master Node. Each RS-485
subnetwork can have up to 63 controllers connected to it; you can still have more
than 63 Master Nodes connected to the Ethernet network.
Ethernet Network
Figure 4.
If you connect to the Ethernet TCP/IP network with the TX3 Configurator, you
can configure any of the nodes in the system. If you connect directly to a
controller 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.

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
