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.

I/O (1-4, G)
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

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.
4 Maximum number of SIMPL Windows analog and digital signals that CN-TVAV
can process.
5 The CN-TVAV has a simulated clock and simulated NVRAM. If power is lost, the
clock and symbols utilizing simulated NVRAM do not maintain previous settings.
6 Due to program size in the CNMSX, the recommended limit of CN-TVAVs
programmed into a CNMSX using the CNXENET+ card is 25 if each room (CNTVAV) also contains a touchpanel. With this configuration, (depending upon the
wiring, it may be advisable to add a CNXHUB), 20 sources may be programmed
with the 25 rooms. If there are no touchpanels are utilized, the recommended limit of
CN-TVAVs is 30. If a Cresnet system has more rooms, either connect additional
CN-TVAVs to another CNMSX or utilize CEN-TVAVs.

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
R <
The required wire gauge should be chosen such that the resistance value is less than
the value calculated in the resistance equation. Refer to the table below.
Wire Gauge Values

Where:
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.
