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.
Figure 16shows a configuration with TX3 controllers connected on an RS-485
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
