Figure 4 Card Access System Using Both Ethernet And Rs-485 Networks - Mircom TX3 Series Installation Manual

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.

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
