3.6 Networking TX3 Panels
Mircom devices such as the Lobby Control Unit, the Card Access Controller, and
the Touch Screen can be networked with the TX3 system through a peer-to-peer
RS-485 network, an Ethernet TCP/IP network, or a combination of Ethernet and
RS-485 networks.
The TX3 Configurator software can connect to any of these network
configurations. How you connect to the network (that is, through TCP/IP, USB,
a modem, or the COM port) determines what devices you can configure on the
network using the TX3 Configurator. The different network configurations are
explained in the rest of this section.

network. Each controller has to have a unique network address on the RS-485
network. Up to 63 unique network addresses can be assigned. If you connect to
