Programmable TV/AV Controller:
CN-TVAV
Description
Functional Description
The CN-TVAV is a multi-purpose television/audio-visual (TV/AV) device controller
that is compatible with SIMPL™ Windows® and can be used as a standard Crestron
remote control system (herein referred to as the Cresnet system) peripheral or as a
“smart” peripheral. As a standard Cresnet system peripheral, the CN-TVAV can be
added as a Cresnet network device to a host Crestron control system with all logic,
infrared (IR) drivers, and serial strings stored in the control system programming
logic. In the “smart” peripheral mode, the CN-TVAV may be programmed to store
and execute SIMPL and SIMPL+ programs.
The CN-TVAV controls the ON/OFF and many or most functions of an attached TV
or AV device. The unit provides operating power to the device and controls the
device through a Crestron SmarTouch infrared probe (STIRP). The CN-TVAV also
provides four Versiports ports (each capable of digital inputs/or digital outputs or
analog inputs) for controlling or monitoring external equipment.
The CN-TVAV may also be enabled and operated with optional Crestron handheld
IR transmitters. To prevent interference from most standard IR frequencies and/or
fluorescent lighting, the CN-TVAV and optional transmitters operate at 455 kilohertz
(kHz). Contact Crestron customer service for further information.
The CN-TVAV may be utilized as a “smart” peripheral, a standard Cresnet system
peripheral, or a “mixed mode” peripheral. For descriptions of the three ways to
perform different functions, refer to the following paragraphs.
In Local Processing Mode, the CN-TVAV functions as a “smart” peripheral. The
built-in CN-TVAV devices (IR Port, Versiport, Com Port, Power Sensor, and IR
Gateway) are accessed and controlled by the SIMPL Windows program loaded into
the CN-TVAV.
NOTE: The CN-TVAV in the Local Processing Mode does not function as a “full
scale” control system and support a local Cresnet system (ie. touchpanels, etc. The
CEN-TVAV may be used as a device controller while supporting a local Cresnet
system.

Programmable TV/AV Controller Crestron CN-TVAV
2•• Programmable TV/AV Controller: CN-TVAV Operations Guide -DOC. 5722B
The CN-TVAV does not support dynamic preset storage that may be required by
certain modules, such as dynamic camera presets, etc. Having a simulated clock and
simulated NVRAM, if power is lost, the clock and symbols utilizing NVRAM do not
maintain previous settings. Therefore, the CN-TVAV may not be suitable for certain
types of local processing applications. For further information, please contact
Crestron customer service.
In Remote Processing Mode, a CN-TVAV may be used as a peripheral within a
host control system program. When this is done, all the functionality of the
CN-TVAV (such as the IR Port, Versiport, Com Port, Power Sensor, and IR
Gateway) is accessed via the host control system program with no programming
within the CN-TVAV. For example, IR can be generated by the CN-TVAV by
programming the host control system only.
The Mixed Processing Mode is a combination of the Local Processing and Remote
Processing Modes. For example, the Versiports can be programmed to control other
equipment from the program in the CN-TVAV and the IR Port can be generated via
the host control system (no IR driver loaded in the CN-TVAV). It is not
recommended to communicate to a port of the CN-TVAV (such as the IR Port)
through a program in the CN-TVAV itself and via a host control system at the same
time.
Physical Description
Shown below is the STIRP and 5-pin connector plug that are supplied with the
CN-TVAV. When connected to the IR port of the CN-TVAV and positioned near an
attached TV or AV device, the STIRP (or other IR device) emits IR signals that
control the attached device. The provided 5-pin connector plug shown may be
connected to the I/O port of the CN-TVAV and used for digital inputs, digital
outputs, and analog inputs to control and monitor up to four external devices.

POWER OUT
WARNING: When the POWER IN cord is plugged into an energized outlet,
POWER OUT becomes energized. Crestron recommends connecting the TV or AV
device before plugging the POWER IN cord into an outlet.
NOTE: The maximum continuous current from the POWER OUT under any
external load shall not exceed a current limit that is suitable for the minimum wire
gauge and maximum length used for the interconnecting cable(s).
NOTE: The maximum load applied to the POWER OUT shall not exceed the rated
voltage and current as specified on the unit.
This receptacle provides AC power (refer to the rear panel label for details) for a TV
or AV device. The receptacle is hard-wired to the POWER IN cord and is not
protected with a fuse. When programmed to sense whether the attached device is
OFF or ON, a large current is used to indicate that the attached device is ON and the
absence of (or very low) current indicates the device is OFF. If the CN-TVAV (or
control system) detects that the device is ON, the program can be coded to not allow
the CN-TVAV to attempt to turn it ON, which would inadvertently turn it OFF. This
is true if the IR driver does not have discrete ON and OFF functions, but only a
POWER function.
POWER IN
This attached power cord supplies operating AC power (refer to the rear panel label
and/or “Leading Specifications” section on page 6for details) to the CN-TVAV and
the POWER OUT port. An internal fuse electrically protects the CN-TVAV circuitry
from excessive power input.

When calculating the wire gauge for a particular Cresnet run, the length of the run
and the load factor of each network unit to be connected must be taken into
consideration. If Cresnet units are to be daisy-chained on the run, the load factor of
each unit to be daisy-chained must be added together to determine the load factor of
the entire chain. If the unit is a home-run from a Crestron system power supply
network port, the load factor of that unit is the load factor of the entire run. The
length of the run in feet and the load factor of the run should be used in the resistance
equation below to calculate the value on the right side of the equation.

R = Resistance (refer to next table).
L = Length of run (or chain) in feet.
LF = Load factor of entire run (or chain).

Cable Configuration for Programming
The CN-TVAV may be programmed through the host control system or directly via
the local RS-232 port. To program the CN-TVAV at the RS-232 port, a modular
cable, an RJ11 to DB9F adapter and 6-conductor modular cable are required. These
components are not supplied but are part of the SmarTouch Programming Kit
(ST-PK). If available, use these components.
When programming, refer to the figure on the next page for a typical connection
diagram. Complete the following steps in the order provided to ensure proper
connection.
WARNING: When the POWER IN cord is plugged into an energized outlet,
POWER OUT becomes energized. Crestron recommends connecting the TV or AV
device before plugging the POWER IN cord into an outlet.
NOTE: The following procedure assumes that a touchpanel is being used as the
user interface. If a wireless hand-held transmitter is utilized, no connections to a user
interface need to be made.
NOTE: The RJ11 to DB9F adapter is available commercially or contact Crestron
customer support for part number 15556. If not available, refer to “Programming
Cable Fabrication Specifications” on page 9.

Special Considerations for Using the RS-232 Port
for Uploading Programs
The CN-TVAV has a single RS-232 console port that is used for uploading programs
and communicating with RS-232 equipment for control purposes. Since the port is
shared, the operation is slightly different from standard Crestron control systems that
have a dedicated RS-232 console ports. When a program is loaded into a CN-TVAV
that uses the TVAVCOM-1 port, the program will initialize but the shared port will
still be attached to the console. The program runs normally, but the TVAVCOM-1
port will effectively be “disconnected” from the system. This is done so other
configurations (such as uploading SIMPL+ modules, setting the IP Table, etc.) can
be done.
After the program is rebooted (using F10 in the Viewport or cycling operating
power), the shared port is taken over by the TVAVCOM-1 port (if the TVAVCOM-1
symbol is present in the program) when the SIMPL program initializes. Note that
SIMPL Windows will not convert the TVAVCOM-1 port if there are no signals or
data coded in the port, or if the symbol is commented out. When the program
initializes, the normal TVAV bootup messages will be issued out the TVAVCOM-1
port, i.e.:
TVAV Monitor v5.10.13 - 03/07/00 - interrupt serial i/o
512k flash memory, 512k SRAM, segment =F900
Press <esc> now to enter debug monitor
If there is a device hooked up to the TVAVCOM-1 port, the bootup message may be
treated as false characters and cause device errors. It is possible to set the baud rate
to DISABLE (pressing F8 while in the Viewport and selecting DISABLE) for the
console port. This will cause the initial bootup message to not be displayed. In order
to obtain communications with the CN-TVAV through the RS-232 port, the
following methods can be used:

6. To set the console baud rate, press F8 and select a new
baud rate. This will force the console to show the bootup
messages at bootup time.
1. Set the Viewport to the baud rate the console is operating at
or use Establish Communications (Alt-B) from the
Diagnostics Menu.
2. Press BREAK (ALT-K) three times in succession and
observe the following reply:
TVAV Console Enabled
STEPS TO PERFORM
If the baud rate was
set to 'disable' for
the console.
If the baud rate was
set to a rate other
than 'disable' and
the rate is known.
If the baud rate was
set to a rate other
than 'disable' for the
console but the rate
is unknown.
The console port is always accessible, regardless of whether or not the program
contains a TVAVCOM-1 port, if the console connection is established via “Establish
Remote Console Connection” on page 20. To prevent the console switchover during
program development, the TVAVCOM-1 port may be commented out. If the
TVAVCOM-1 port is not programmed in SIMPL Windows (if the definition is
present but the Port contains no data), then the console port will never be taken over
and is always accessible.
Cable Configuration for Normal Operation
When operating the CN-TVAV under normal conditions, refer to the figure on the
next page for a typical connection diagram.
WARNING: When the POWER IN cord is plugged into an energized outlet,
POWER OUT becomes energized. Crestron recommends connecting the TV or AV
device before plugging the POWER IN cord into an outlet.
CAUTION: If making connections to the CRESNET modular port, do not use
6-conductor telephone cables. Telephone cables are wired in a crisscross fashion and
are not compatible with Crestron equipment. Use the modular cable provided.
CAUTION: If making connections to the Cresnet peripherals from the CRESNET
port, refer to “Cresnet Modular Cabling” on page 7.
NOTE: If making connections to Cresnet peripherals from the CRESNET port,

Identity Code
Every equipment and user interface within the Cresnet network requires a unique
identity code (NET ID). These codes are recognized by a two-digit hexadecimal
number from 03 to FE.
When used in the Remote Processing Mode or Mixed Processing Mode, each
CN-TVAV in the Cresnet system needs a NET ID that matches an ID code specified
in the SIMPL Windows program. The NET ID of the CN-TVAV is factory set to 50.
The NET IDs of multiple units must all be unique and changed from a PC via
SIMPL Windows or VisionTools™ Pro-e (VT Pro-e).
NOTE: VT Pro-e is a Windows compatible software package for creating Crestron
touchpanel screen designs.
The method for changing the unit’s NET ID is identical regardless of the software
chosen. Complete the following steps to change the NET ID.
1. Attach one of the CN-TVAVs to the control system (verify that the
software is running).

2. From the SIMPL Windows or VT Pro-e menu, select Tools | Viewport
to open the Crestron Viewport.
3. From the Viewport menu, select Functions | Set Network ID. The
software checks the baud rate and then opens the “Set Network ID”
dialog box.
4. In the “Set Network ID” dialog box, select the CN-TVAV from the
Current Network Devices text window.
5. From the Choose the new network ID for the selected device (Hex): text
box, select the new Net ID for the CN-TVAV.
6. Click Set ID to initiate the change. This will display the “ID command
has been sent” dialog box.
7. In the “Command Complete” dialog box, click OK.
8. In the Current Network Devices text window, verify the new NET ID
code.
9. In the “Set Network ID” dialog box, click Close.
NOTE: The new NET ID code may also be verified by selecting Diagnostic |
Report Network Devices in the Viewport.
10. Repeat this procedure for each CN-TVAV to be added to the Cresnet
system.
Loading Crestron Control Software
Crestron control software is available in an electronic form; CD-ROM, email, or
from Crestron’s website. Regardless of how and from where the software is
obtained, this section provides the necessary installation steps. Before performing the
procedures in this section, refer to “Cable Configuration for Programming” on
page 8for cabling instructions.
Installing Crestron Development Tools
Crestron provides software tools for programming the CN-TVAV. Even if only the
control software is being loaded into the hardware and there are no plans to do any
programming, some Crestron development software must be installed on the PC.
Currently, Crestron programming is accomplished with the use of the following
development tools listed in the table shown on the next page.
NOTE: If the intent is to load software developed elsewhere, install SIMPL
Windows only. To program the CN-TVAV, install all three applications.
NOTE: The latest versions of these applications are available from Crestron’s
website (www.crestron.com). Crestron ControlCD also contains a version (which
may not be as current as the website version). To obtain a free copy of the CD-ROM,
contact Crestron at 1-888-CRESTRON [1-888-273-7876]. Alternatively, complete a
literature request from the Crestron website to obtain one.

Crestron Development Tools
DEVELOPMENT TOOL DESCRIPTION
SIMPL Windows Used to program the CN-TVAV.
VT Pro-e Used to design touchpanel layouts and to program
SmarTouch Systems.
DEAL for Windows Used for learning (using the optional CNXLIR) and
maintaining IR driver files.
Before installing any development tools, confirm that all other applications such as
Microsoft®Office, etc. are closed. The website and CD provide instructions for
installing the various tools. When initiating a custom install from the CD, the user is
presented with a list of the software programs, documentation, and other resources.
For each item, set or clear a checkbox to the left of the item to direct the installation
program whether to install that component onto the hard drive. The size of the each
item installed determines how much disk space is required. Each development tool
contains a help file that can be opened from the Help pull-down menu. Refer to these
files for additional information.
Initial Setup
To avoid any procedural errors,
follow the steps in the order
provided.
After installing the desired development tool, various job files may be obtained from
Crestron or other sources. Using Windows
Explorer™, complete the following steps.
These steps ensure that all job files reside on the hard drive (C:)in the Directory
\CRESTRON\PROJECTS\MYJOB.
1. Navigate to the SIMPL directory on the hard drive. Assume that the
default install directory is C:\CRESTRON.
2. Create a new folder for the project files. Although the folder where the
files are placed is not critical, it is easier to manage projects if a logical
structure is created. For example, create a new folder, called
PROJECTS, underneath the CRESTRON directory. Create another
folder, called MYJOB, under PROJECTS for the current job. The
resulting pathname is C:\CRESTRON\PROJECTS\MYJOB.
3. Copy the supplied files into the folder created in the last step. The
source of the file determines the procedure.
From a floppy disk: Most floppy disks sent from Crestron contain a
common directory structure designed to make it easier to organize files.
Copy the entire contents of the disk(s) including the directory structure.
From an EXE file: If a job is downloaded from the Crestron website
or is received via email, all files may have been compressed into a
single, self-extracting archive. This archive has an EXE extension.
First, copy the EXE file into the directory stated in step 1, then double-
click on the file name to begin decompressing the file. The program
asks for a location for the extracted files. In this case, browse for the
same directory where the archive was copied. (Once files are extracted,
retain the original EXE file in case files need to be restored.)
From a ZIP file: If the downloaded job is from Crestron’s website or
e-mail, all files may have been compressed into an archive file with a
ZIP extension. For this ZIP file to be used, in SIMPL Windows, select
File | Import Archived Program. This will open a dialog box similar
to the one shown on the next page.

Operations Guide -DOC. 5722B Programmable TV/AV Controller: CN-TVAV •• 15
Import an Archived (ZIP File) Program Dialog Box
The job may be copied to any folder or directory, and the User IR, User
Module, and SIMPL+ files will be copied to the proper directories. If a
version of SIMPL Windows lower than 1.30.01 is being used, copy the
ZIP file into the job directory stated in step 1, then extract the files with
a program called WinZip. Obtain a copy of this program from their
website (www.winzip.com) on the Internet. Extract the files into the
same directory where the archive was copied. Once files are extracted,
retain the original ZIP file in case the files need to be restored at any
point. The User IR, User Module, and SIMPL+ files will need to be
copied to their proper directories manually.
File Types
There are quite a few file types involved with Crestron control software. This section
explains the different types that might be encountered in each directory. In many
cases, the supplied software is grouped into a number of subdirectories. The intent is
to keep files organized. For example, after copying the files to the hard disk, the
directory structure may appear as shown below.

NOTE: In this example, the Vt3501 and Vt3502directories represent two
touchpanels that are part of the entire remote control system. Consult the connection
sheets or other supplied information to determine which directory corresponds to a
given touchpanel.
Ops Subdirectory -The files (described in the table below) in this subdirectory
contains the CN-TVAV operating system with which the program was tested. Ensure
that the operating system version currently loaded is equal to or newer than the
version included here, so that the program runs properly. For help with uploading an
operating system, refer to “Updating the CN-TVAV” on page 22.
File Types in Ops Subdirectory
FILE TYPE DESCRIPTION
.upz
This is a control system file. For more information regarding these
files, refer to "Updating the CV-TVAV".
Programs Subdirectory -The files (described in the table below) in this
subdirectory contain the system program. This is the main program that loads into
the CN-TVAV and determines the exact functionality.
File Types in Programs Subdirectory
FILE TYPE DESCRIPTION
.asv SIMPL Windows auto-save file.
.bin This is the executable code for the CN-TVAV.
.dip This is the default IP Table that contains the IP addresses of all of the ethernet devices in the system. It is generated when the program is
compiled.
.sig This file contains information required by Test Manager (see SIMPL Windows help for more information) for debugging programs in real-
time. It is generated each time the program is compiled.
.smp
This is the SIMPL-C file that is generated from the SMW file when a
program is compiled. In SIMPL Windows version 1.18 or lower, this
file is what actually gets compiled into the BIN file. In versions after
1.18, this file may or may not be generated and but is not required.
.smw This is the SIMPL Windows program file. It contains the source code
for the main system program.
.sm2 SIMPL Windows program backup file.
Userdb Subdirectory -The files (described in the table below) in this subdirectory
is a user database IR driver that is needed to interface with certain IR-controlled
devices. This driver differs from Crestron database IR drivers in that the former are
included as part of a Crestron Database.
File Types in Userdb Subdirectory
FILE TYPE DESCRIPTION
This is a user IR driver file. It is needed during the convert/compile
process in order to properly compile the program. If recompilation of
the program is necessary, use the Import Program option or copy any
IR files received into the default user database directory (see SIMPL
Windows help for more information). Alternatively, set the SIMPL
Windows userdb
directory to the directory where the macros exist. (In
SIMPL Windows, this is accomplished from the Directories tab by
selecting
