7.1 Adding a Controller
The TX3 telephone access system may be integrated with other controllers, such
as the TX3-CX Card Access system and Elevator Restriction Unit, through a
peer-to-peer connection via the RS-485 bus, an ethernet TPC/IP network, or a
combination of RS-485 and ethernet networks.
Connecting a controller to an RS-485 network requires that the controller have a
unique ID address on the RS-485 network (valid addresses range from 1 to 63).
See the installation manual for your controller for instructions on how to set the
ID address for your controller.
To connect a controller to an ethernet network, the controller must have an IP
Module. Once the controller is connected to the ethernet network and has an IP
address, the controller is recognized as a Master Node on the TX3 system.
To create a combination ethernet and RS-485 network, you connect one or more
controllers to the RS-485 network on a Master Node. The controllers connecting
to the Master Node’s RS-485 network are Slave Nodes. Each controller on the
RS-485 network (including the Master Node) must have a unique ID address on
the RS-485 network. See the installation manual for your controller for
instructions on how to set the ID address for your controller.
Note: Ensure that each controller has a unique address (IP and/or RS-485
ID address) on the network it is connected to.
To integrate another controller on an RS-485 network
1. Ensure the Telephone Access System and the controller are setup and
ready for operation.
2. Turn the power OFF for all units on the network.
3. Connect the controller to the Telephone Access System via the RS-485 bus
using the RS-485 connectors.
4. Turn the power ON for all units on the network.
5. Connect the PC to either the Telephone Access System or controller using
the USB port.
6. Use the TX3 Configurator Program to add and configure the controller to
the network.
