Figure 1 shows a basic Card Access System with one card access controller and
two card readers. The maximum distance between the card access controller and
the card readers is 500 feet.
Figure 1.
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 2.
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
