The latest addition to the TX3 family of access control units, the TX3-CX-1 has all the features for an entry level access control application with the flexibility for scalability. An innovative PoE controller with a built-in proximity reader that can be used stand alone or networked using either RS-485 or TCP/IP. Simplicity Simply mount onto a single gang electrical box and connect CAT-5/6 cable for both power and network communication. Flexibility Power the TX3-CX-1 by either 12 VDC, 24 to 48 VDC or PoE. Network the controller by RS-485 or TCP/IP. Versatile The controller has a built- in 125 KHz proximity reader for interior applications. Any second Wiegand card reader can be added for outside the door. Scalable The TX3-CX-1 may be used stand alone or networked to other TX3 platform devices for up to 63 nodes, if using the RS-485 network. Essentially no limit if TCP/IP is used.
