6 Adding Controllers and
Accessories
This chapter provides information about adding additional controllers on the
same network as the Telephone Access System.
This chapter explains
• Adding a Controller
• Installing the TX3-P300-HA Card Reader
6.1 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, 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 address, RS-
485 ID, or both) 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 set up and
ready for operation.
