Crestron CNXTA CNX Telephone Audio Interface Card
CNX Telephone Audio Interface
Card: CNXTA
Description
Functional Description
The CNX Telephone Audio Interface Card, CNXTA, allows access and control of a
Cresnet system through standard telephone lines. The CNXTA recognizes and
generates telephone Dual-Tone Multifrequency (DTMF) signals. When the CNXTA
is installed, these signals are used by a Cresnet system to remotely operate any
device controlled by the system. The CNXTA also recognizes caller ID (CID) and
CID on call waiting.
The CNXTA uses audio messages as voice prompts and responses. These files can
be recorded as WAV files on a personal computer (PC) using Microsoft®
Windows™ Sound Recorder, converted to PCM format, and transferred to the
CNXTA. Pre-recorded WAV message files can be downloaded from Crestron’s
website (www.crestron.com)
A Cresnet system with the CNXTA may be programmed to respond to incoming
telephone tones or sequence of tones. For example, pressing 1 or 12 from a telephone
(after connecting to the system) may be used to activate an air conditioning system
and the CNXTA would respond with “Command accepted, air conditioning is on”.
The system may also be programmed to dial-out and play a recorded message when
a specific input, such as from a security device, is received. By using CID
information, the system can be programmed to allow access only from a specific
telephone or even limited access from other lines.
.
Physical Description
The CNXTA, shown on the next page, is a circuit board fastened to an aluminum
faceplate. The card is installed into an unoccupied slot in a Crestron CNX
Generation Control System. The faceplate contains two audio ports and one
telephone port that are described on the next page.

As of the date of manufacture, this unit has been tested and found to comply with
specifications for CE marking.
NOTE: This device complies with part 15 of the FCC rules. Operation is subject to
the following two conditions: (1) this device may not cause harmful interference, and
(2) this device must accept any interference received, including interference that may
cause undesired operation.

WAV File Audio Messages
The CNXTA audio messages are used for system prompts and responses. These files
are recorded as WAV files on a PC using an audio utility such as Sound Recorder
that is packaged with Microsoft Windows 95/98/NT™. Files from other sources may
also be converted to a CNXTA acceptable format by using this or a similar utility.
Many other audio utilities are available commercially or as shareware.
NOTE: If the Sound Recorder program is not available on the PC, select Start
Help at the Windows taskbar. Click on the Index tab and type in Sound Recorder.

Configure CNXTA
The CNXTA card is configured using the Crestron Viewport. To interface directly to
a CNXTA card, establish communication with the control system. From the
Viewport Functions menu, select Configure CNXTA Telephone Audio Interface
Card (CNX Only). From the Select Card Slot dialog box, select the slot where the
CNXTA is located and the Viewport will attempt to locate a CNXTA at that slot. If it
is unable to determine which card is in the selected slot or if the card in the selected
slot is not a CNXTA, the Viewport will not allow you to continue. If the control
system cannot be connected to, configure the CNXTA offline by selecting Offline
from the Select Card Slot dialog box. The following paragraphs describe the contents
of the CNXTA Telephone Audio Interface Card Configuration dialog box (shown on
the next page):

NOTE: Duplicate file names cannot be moved, exported to nor stored in the

accepted, the file will be displayed in the list with the disk icon.

CNXTA Configuration Dialog Box
CNXTA File List
Overview
The file list contains all files that are loaded into the CNXTA as well as the files that
are stored on the PC. The entries in the File # column correspond to a location that a
file is stored. Two icons (as shown in the legend box) represent whether a particular
file is stored on the PC or loaded into the CNXTA. If the configuration dialog is not
in offline mode, the file list will show the files that have been loaded into the
CNXTA on initialization.
Selected File Options Dialog Box
The selected file options dialog box opens by right-clicking on a file list entry. The
dialog box (shown below with all options available) allows for file manipulation in
the list.
Selected File Options Dialog Box
Operations & Installation Guide - DOC. 8144A CNX Telephone Audio Interface Card: CNXTA • 15
CNX Telephone Audio Interface Card Crestron CNXTA
If only one item is selected and it contains a reference to a file that is stored in the
CNXTA (it has the card icon), the Move command will be available (not grayed out).
When selected, this will open a dialog box that prompts the user for a new file
position. If the user selects anything but an empty file position as the new location, an
error message opens and the move will not occur. Otherwise, the file will be
immediately moved to the new location in the CNXTA card. Delete becomes
available if any entry is selected (including multiple-selection). If the entry is stored in
the CNXTA, the file will be permanently removed from the card. If the file is located
on the PC, the entry will be cleared. The Choose File command is available if only
one entry is selected and does not contain a file (it is empty). This command will
prompt the user to select a file to show in the selected list entry. Double-clicking on
an empty entry will also open the selected file options dialog box. This command is
the default item for the list and is normally available. When clicked, Select All
highlights and selects all of the entries in the list. This command is always available.
Export File List Button
Once files are added to the file list, they can then be exported to a CNXTA file with a
XTA extension. This XTA file will store the data as well as file positions associated
with any list. This is very useful for distributing sets of data with a program. If files
were chosen and then Send New Files to CNXTA was selected, those files will still
be available for exporting because a temporary file location reference is maintained
on disk. Once the configuration utility is closed and re-entered, these files will no
longer be available for exporting because the utility has no location reference.
Import File List Button
When importing a file, a custom file selection dialog box is opened. This dialog box
displays details about the currently selected XTA file. Specifically, the file count and
the file position range. This dialog box also allows the user to import data with an
offset. This means the new position for a given file will be the stored file position plus
the file offset which is useful if a user is combining sound elements from multiple
sources. For example, a SIMPL+ module might require five sounds and another might
require 10. If both SIMPL+ modules assumed that the sound files they were looking
for started at file position 1, there would be a conflict. This way, if the SIMPL+
module supports an offset, the module can be distributed with the necessary sound
files and the user can import them to an available section of file positions.
Send New Files to CNXTA Button
If new files are selected using Choose File, the Send New Files to CNXTA button
will be available. Clicking this button will transfer all of the selected files from the PC
to the CNXTA card. When the transfer is successful, the file list will be updated to
show that the files are now stored on the card and will be shown with the card icon. If
working in Offline mode, this button is not available (grayed out).
Programming with SIMPL Windows
SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use
programming language that is completely integrated and compatible with all Crestron
system hardware. The objects that are used in SIMPL Windows are called symbols.
SIMPL Windows offers drag and drop functionality in a familiar Windows
environment.

SIMPL Windows is Crestron Electronics' software for programming Crestron control
systems. It provides a well-designed graphical environment with a number of
workspaces (i.e., windows) in which a programmer can select, configure, program,
test, and monitor a Crestron control system.
The next three sections describe the basic SIMPL Windows program that utilizes the
CNXTA. The sections detail how the program works with textual descriptions and a
block diagram.
NOTE: The following descriptions assume that the reader has knowledge of SIMPL
