Crestron CN-TVAV Programmable TV/AV Controller

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.

Operations Guide - DOC. 5722B Programmable TV/AV Controller: CN-TVAV •• 1

Programmable TV/AV Controller Crestron CN-TVAV

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.

CN-TVAV Accessories

Pins 1-4 of this Versiport may individually be used as programmable digital inputs,

digital outputs, analog inputs, or any combination of each. Digital inputs are rated

0 - 24VDC, 20K ohms input impedance, logic threshold 1.25VDC. Digital outputs

offer 250 milliamp sink from maximum 24VDC; catch diodes provide transient

protection for use with “real world” loads. Analog inputs are rated 0 - 10VDC,

protected to 24VDC maximum, 20K ohms input impedance; pin-programmable 2K

ohms pullup resistor to +5V. The pin labeled G is the common ground for pins 1-4.

IR

This 3.5mm mini-jack is used by the STIRP (provided) to control an attached TV or

AV device. The jack accepts mono (2-conductor) or stereo (3-conductor) mini-plugs.

Multiple IR drivers may be loaded into the CN-TVAV and, with the use of a

Crestron ST-SPL IR Splitter, up to five AV devices may be controlled.

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 6 for details) to the CN-TVAV and

the POWER OUT port. An internal fuse electrically protects the CN-TVAV circuitry

from excessive power input.

CN-TVAV Indicators

There are 11 LED indicators located on the front panel of the CN-TVAV. For the

Programmable TV/AV Controller Crestron CN-TVAV

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.

Resistance Equation

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

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:

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.

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).

12 •• Programmable TV/AV Controller: CN-TVAV Operations Guide - DOC. 5722B

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 8 for 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.

Programmable TV/AV Controller Crestron CN-TVAV

After installing the desired development tool, various job files may be obtained from

Explorer™, complete the following steps.

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.

Crestron or other sources. Using Windows
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.

14 •• Programmable TV/AV Controller: CN-TVAV Operations Guide - DOC. 5722B

Crestron CN-TVAV Programmable TV/AV Controller

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.

7. Select Diagnostics | Check Operating System Version (alternatively,
depress F5) from the Viewport. The Viewport may display a window
as it scans various baud rates. Eventually, a message should appear in
the Incoming section showing a version number. Such a response
indicates that communications have been established.

If a “No Communications with Rack” error message opens, proceed to
“Troubleshooting Communications” on page 20. If the baud rate of the
CN-TVAV was something other than 38400, the software
automatically adjusts the baud rate to 38400.

Establish Remote Console Connection

Instead of communicating by plugging into each CN-TVAV in a large installation
via RS-232 in order to upload programs/firmware/etc., the CN-TVAV console can be
accessed from the control system to which it is a peripheral. Complete the following
steps to establish communication with the CN-TVAV.

Updating the CN-TVAV

Much like a Crestron control system, the CN-TVAV contains an Operating System
and a Monitor ROM. Although both are separate components, they are packaged
together in a single file referred to as a Control System Update File. Control system
update files have the UPZ extension. It is often necessary to update a control system
or CN-TVAV if new features have been implemented (such as support for new
hardware or new language constructs) or if programming "bugs" have been
corrected.

CAUTION: Update files are designed for specific devices. If an update file is
loaded into a device other than for which it was intended, it may lockup the device
that would then have to be returned to Crestron. Update files with a “S” designator
for the ST-CP, “V” designator are for CEN/CN-TVAV, “W” for CNRACKX/-DP,
and “X” for the CNMSX-AV/Pro. These devices are able to recognize and reject
incorrect update files. However when updating, do not ignore any Crestron Viewport
warning prompts or messages.

NOTE: SIMPL Windows version 1.40.07 or later is required to update the UPZ.
When the UPZ is loaded, the program and SIMPL+ modules will be erased so they
must be reloaded after a UPZ is loaded.

The following procedure is recommended to load a new UPZ file into the
CN-TVAV.

1. Establish communications with the CN-TVAV by performing
“Obtaining Communications” on page 18.

2. From the Crestron Viewport, select File Transfer | Update Control
System as shown below.

Accessing the Update Control System Dialog Box

3. The Update Control System dialog box, shown on the next page, offers
the option to enter the path name of a new update file. If the path name
is not known, use the Browse button to navigate to a list of available
update files. When browsing, choose only update files with a UPZ
extension.

Programming with SIMPL™ Windows® or SIMPL+

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 and/or CN-TVAV.

The next three sections describe a CN-TVAV within SIMPL Windows. The first
section details the programming modes of the CN-TVAV, the second section
describes a typical programming application, and the third section provides the
location of example programs.

NOTE: The following descriptions assume that the reader has knowledge of SIMPL
Windows. If not, refer to the extensive help information provided with the software.

NOTE: If programmed with SIMPL Windows, the CN-TVAV may be loaded with
a BIN file of 250K or less, and for SIMPL+, the unit is limited to 256K. Descriptions
and examples are provided in the following sections.

24 •• Programmable TV/AV Controller: CN-TVAV Operations Guide - DOC. 5722B

Crestron CN-TVAV Programmable TV/AV Controller

Programming Modes

The CN-TVAV may be utilized three ways to perform different functions; Local,
Remote, and Mixed Processing Modes. Similar to as shown below, the CN-TVAV
and its supporting devices have been added to SIMPL Windows.

New SIMPL Windows’ Devices for Programming the CN-TVAV

NOTE: The CN-TVAV contains no NVRAM. It has “simulated” NVRAM,
meaning that conventional (volatile) memory is mapped into the NVRAM space.
When power is disconnected, the contents of memory are lost. Rather than restrict
the usage of NVRAM symbols (such as RAM, SMEM, etc.), the mapping allows
some SIMPL programs to use NVRAM for runtime calculations. Runtime
calculations are not essential if power is lost and are reset at startup (i.e. such as
putting names into an SMEM when using the QUE symbol).

NOTE: The CN-TVAV also does not have a hardware clock. The clock must be
reset at startup.

NOTE: The compiler will detect usage of NVRAM symbols or DEVICE SYSTEM
(real time clock driver) and flag it in the error log as warnings when programming.

Operations Guide - DOC. 5722B Programmable TV/AV Controller: CN-TVAV •• 25

Programmable TV/AV Controller Crestron CN-TVAV

Local Processing Mode

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.

In the Local Processing Mode, the CN-TVAV is programmed to access and control
the local hardware ports. Use the Configuration Manager workspace (Project |
Configure System) in SIMPL Windows to select and configure all the devices that
need to be included into the system. From the Control Systems folder in the Device

Library, select “CN-TVAV Local Processing”. Drag and drop the CN-TVAV into
Network System View and the symbol appears as shown below.

Network System View of the Local Processing Mode CN-TVAV in SIMPL Windows’ Configuration Manager

NOTE: SIMPL Windows contains Intersystem Communication (ISC) devices that
provide a simple method to cross link analog, digital, and serial data signals between
a control system and a Mixed Processing Mode network device (ie. CN-TVAV). The
CN-ISC is automatically added but when in a Local Processing Mode or Remote
Processing Mode, it is not used and may be commented out. For further information,
refer to “Typical Programming Example” on page 28.

Remote Processing Mode

In the Remote Processing Mode, the CN-TVAV does not contain a program. The
slots and Cresnet devices are accessed solely from the host control system that
generates all the proper network packets to control the hardware. To utilize a
CN-TVAV as a peripheral, drag and drop the "CN-TVAV Remote Processing" from
the "Network Control Modules" onto the Net-Device slot in the control system (or
Cresnet Units in Network System View). In the Program Manager workspace
(Project | Program System), the CN-TVAV appears in the program view as shown
on the next page.

cross link analog, digital, and serial data signals between a control system and a
Mixed Processing Mode network device (ie. CN-TVAV). The CN-ISC is
automatically added but when in a Local Processing Mode or Remote Processing
Mode, it is not used and may be commented out. For further information, refer to
“Typical Programming Example” on page 28.

Crestron CN-TVAV Programmable TV/AV Controller

Program View of the Remote Processing Mode CN-TVAV in SIMPL Windows’ Program Manager

Mixed Processing Mode

SIMPL Windows contains ISC devices that provide a simple method to cross link
analog, digital, and serial data signals between a control system and a Mixed
Processing Mode network device (ie. CN-TVAV). The CN-ISC is automatically
added and the primary advantage when using ISC devices is the memory savings for
the control system. The size of the program in the control system decreases because a
portion of the program resides in the network device (CN-TVAV). For further
information, refer to “Typical Programming Example” on page 28.

Combinations of Local Processing Mode and Remote Processing Mode can be used.
A program residing in the CN-TVAV can perform logic (SIMPL and SIMPL+ code)
and access the local hardware ports. A peripheral definition can also reside in the
host control system and access the CN-TVAV local hardware. For example, it is
possible that the TVAVIR-1 be driven from the host control system and the
CN-TVAV.

Only the TVAVIR-1 and TVAVIO-5 can be controlled by both the host control
system and the CN-TVAV, logic can exist in both the remote and local programs.
The TVAVIRGW and TVACOM-1 can be controlled by only one program, either
remote or local, the ISC(s) are used to share logic between programs. If the
TVAVIRGW or TVAVCOM-1 is defined in the local program, this information will
not be shared with the remote program even if defined in the remote program and
ISC(s) must be utilized.

NOTE: In the diagram on the next page, only the first port/channel of the
CN-ISC(R) device is shown for clarity.

Typical Programming Application

Refer to the diagram below. In this programming application, a CNMSX-PRO is
used as the host control system. An RS-232 controlled VCR is physically wired to
the CN-TVAV. A module is created that has PLAY, STOP, FFWD, REW, PAUSE
and RX$ on the inputs and PLAY-F, STOP-F, FFWD-F, REW-F, PAUSE-F, and
TX$ on the outputs. If programmed without the CN-ISCs, the module would be
added into the CNMSX-PRO program and TX$ and RX$ connected to the
TVAVCOM-1 port to control the VCR. With the CN-ISCs, the module is put inside
the CN-TVAV, and TX$ and RX$ connected to the TVAVCOM-1 locally in the
CN-TVAV. The transport controls and feedback would be connected to the CN-ISC
symbol.

transport over Cresnet (containing the destination Cresnet ID, Slot 5, and Port 1).
The receiving CN-TVAV would decode it, and send it to Slot 5, ISC 1, Signal 1,
which would activate the signal TVAV-VCR-PLAY that would put the VCR into
the Play Mode. The return path for TVAV-VCR-PLAY-F is similar.

Internal Fuse Replacement

The circuitry of the CN-TVAV is electrically protected by an internal fuse. If the
fuse blows (opens), no power is provided to the circuitry (the POWER OUT
receptacle remains energized). To replace the fuse, perform this procedure. The only
tools required are a grounding strap (or grounded work station) and a #1 Phillips tip
screwdriver.

WARNING: Use extra caution when working with 100-125VAC or 220-250VAC.
These voltages present an extreme hazard if inadvertent contact is made. Make sure
that the POWER IN line plug is disconnected from the power source before
performing this procedure.

Crestron CN-TVAV Programmable TV/AV Controller

CAUTION: The CN-TVAV contains electro-static discharge (ESD) sensitive
devices. Perform the following procedure while wearing a grounding strap that is
properly grounded or on a grounded work station to avoid damaging the unit.

CAUTION: If disconnecting the CN-TVAV from the power source, DO NOT pull
the POWER IN cord. Disconnect power by pulling the POWER IN plug from the
source.

NOTE: The internal fuse only protects the CN-TVAV circuitry. This fuse does not
protect the POWER OUT receptacle.

1. Disconnect the POWER IN plug from the power source.

NOTE: Although not required, it is recommended to label and disconnect each
cable (POWER IN line excluded) from the rear panel ports of the CN-TVAV.

2. Turn the CN-TVAV over to bottom-side up.

3. Refer to the diagram below. Using a #1 Phillips screwdriver, remove
the four cover screws.

unit rack mounting and do not accommodate the cover screws. Do not install the
cover screws into the inner-most screw holes.

10. Install the four cover screws that were removed in step 3 into the
outer-most screw holes and tighten to finger-tight, then using a #1
Phillips screwdriver, tighten an additional 1/8-turn.
