Introduction

About This Manual

This manual provides information on the Extron AVT 100
Analog TV and Cable Demodulator, and discusses how to
install and operate it.

About the AVT 100 Demodulator

The Extron AVT 100 is an audio/video demodulator that
provides cable and television tuning for integration into
professional A/V environments. The TV band provides
reception of over-the-air TV (antenna) and CATV (cable)
channels. Channels 2 through 125 are available in the United
States and other countries that use the NTSC standard.
Channels 48 through 855 are available in countries in which the
PAL standard is used.

N In Japan, which uses the NTSC standard, channels 1

through 62 (antenna) and 1 through 63 (cable) are
available, on different frequencies from the USA.

The AVT 100 may receive signals from a cable input or TV
antenna. It is controllable from the front panel or through
software via the RS-232 port.

The AVT 100 also provides wired IR for extended range infrared
(IR) operation. The optional AVT 100 IR Remote Control and
the Extron IR Link Signal Repeater are available separately to be
used in conjunction with this feature.

Models

Two models of the AVT 100 are available:

• AVT 100N (NTSC version) — Handles NTSC signals

only. This version is used in the USA, Japan, and some
other countries.

• AVT 100P (PAL version) — Handles PAL signals only.

This version is used in Great Britain and other nations that
use the PAL standard.

These two models have different radio frequency (antenna)
connectors, but in all other functionality, they are identical.

Features

Antenna (TV) and cable (CATV) channel reception — A full

range of antenna and cable channels are available.

cable and antenna modes.

99 presets — Presets can be associated with channels using SIS

programming, the IR remote control, or the AVT
Windows-based control software. The AVT provides 99
programmable channel presets for TV and 99 for cable.

Stored presets can be used to recall the corresponding
cable or antenna channel in preset mode. With SIS
commands, presets can be recalled in tune mode as well as
preset mode.

Audio and video muting — Enables the audio and video

outputs to be individually muted through the appropriate
SIS command, the IR remote, or the Windows-based
control software.

UL requirements for rack mounting

The following Underwriters Laboratories (UL) requirements
pertain to the safe installation of the equipment in a rack.

1. Elevated operating ambient temperature — If the

equipment is installed in a closed or multi-unit rack
assembly, the operating ambient temperature of the rack
environment may be greater than room ambient
temperature. Therefore, install the equipment in an
environment compatible with the maximum ambient
temperature (Tma = +113 °F, +45 °C) specified by Extron.

2. Reduced air flow — Install the equipment in a rack so that

the amount of air flow required for safe operation of the
equipment is not compromised.

3. Mechanical loading — Mount the equipment in the rack so

that a hazardous condition is not achieved due to uneven
mechanical loading.

4. Circuit overloading — Connect the equipment to the

supply circuit and consider the effect that circuit
overloading might have on overcurrent protection and
supply wiring. Appropriate consideration of equipment
nameplate ratings should be used when addressing this
concern.

5. Reliable earthing (grounding) — Maintain reliable

grounding of rack-mounted equipment. Pay particular
attention to supply connections other than direct
connections to the branch circuit (e.g., use of power strips).

Rack mounting procedure

To rack mount the AVT,

1. If feet were previously installed on the bottom of the

AVT 100, remove them.

Initiating Auto-Scan

When Auto-Scan is enabled, the AVT 100 scans all channels and
saves to memory those with an active signal.

To initiate automatic scanning, press and hold both Channel
buttons. After about 2 seconds, the AVT 100 scans through the
channels and saves them to memory.

Adding and deleting channels

Auto-Scanned channels can be added to or removed from
memory individually by using SIS commands or the Windows­based control software. (See chapter 4, “Software Configuration
and Control,” for further information.)

Special Functions

The AVT 100 offers some special functions that are accessible
only by using SIS commands, the AVT 100 Remote, and the
Windows-based control software. Refer to chapter 4, “Software
Configuration and Control,” or the AVT 100 help file for the
commands to enable these functions.

Locking front panel controls (executive mode)

Executive mode disables all front panel controls, locking out the
user from those functions. Putting the AVT 100 in this mode
enhances security by protecting against inappropriate or
accidental changes to settings.

When the AVT 100 is in executive mode, all serial port
commands remain enabled.

When executive mode is enabled, the AVT 100 displays the

Selecting tune or preset mode

Two channel selection modes are available: Tune and Preset.
You can use the Windows-based control software, SIS
commands, or the AVT 100 Remote to switch between modes.

• In Tune mode, the Channel up and down buttons

increment and decrement by one channel with each press
of the button. If a button is held down for 2 seconds, the
channels tune rapidly up or down until the button is
released. Tune mode is the factory default.

• In Preset mode, the Channel buttons step up or down

through presets that have been associated with channels
via SIS commands, the AVT 100 Remote, or the Windows­based control software.

N Presets can be recalled via SIS commands, the Windows-

based control software, or the AVT 100 Remote in both
tune mode and preset mode.

Presets

The AVT 100 provides 198 programmable presets—99 for
antenna and 99 for cable. Presets are associated with channels
by SIS commands (see chapter 4, “Software Configuration and
Control”), the AVT 100 Remote (see “Using the IR Remote
Control for AVT 100,” later in this chapter), or via the Windows­based control software (see the software’s help file).

Channel presets that are programmed while the AVT is in either
antenna or CATV mode remain exclusive to the mode in which
they were saved.

The following table shows the ranges of channel numbers that
may be preset.

When the AVT 100 is in tune mode and a preset is recalled via
the appropriate SIS command, the AVT 100 Remote, or the
Windows-based control software, a stored preset recalls the
cable or antenna TV channel that was programmed for it. When
you select a preset in either tune or preset mode, its preset
number is displayed for 2 seconds. Then the display changes to
the channel number associated with the selected preset.

Example: If preset 30 is selected via the Channel buttons in
Preset mode, the digital display shows the following:

After 2 seconds, the digital display shows the channel number
(28 in this example) associated with preset number 30.

To overwrite a preset and change its channel, enter the SIS
command or the Windows-based control software selection, or
press the appropriate buttons on the IR remote control to save a
different channel to that preset number. See chapter 4,
“Software Configuration and Control, for information on
programming the presets using SIS commands.

Muting the audio and video outputs

Audio and video outputs can be individually muted through
the appropriate SIS command, the IR remote control, or the
Windows-based control software. (See chapter 4, “Software
Configuration and Control” or the AVT 100 help file for further
information.)

Selecting the audio output mode

You can select the audio output mode (mono or stereo) using SIS
commands or the Windows-based control software. (Mono is
the factory default.)

On PAL models, the following four audio selections are
available if a dual channel is detected:

• L-L — Select the left audio channel for dual mono output.

• R-R — Select the right audio channel for dual mono

output.

Selecting the PAL broadcasting standard

There are several different PAL broadcasting standards. You
can select the appropriate standard using SIS commands (see
chapter 4, “Software Configuration and Control) or the
Windows-based control software (see the software program’s
help file).

Selecting the cable TV frequency (NTSC only)

You can select the CATV frequency (Standard, IRC, HRC, or
Japan standard) so that your AVT 100 is compatible with the
frequency used by your cable provider. You can select the
frequency using SIS commands (see chapter 4, “Software
Configuration and Control”) or the Windows-based control
software (see the software program’s help file).

Using the IR Remote Control for AVT 100

The optional hand-held AVT 100 IR Remote Control lets you
remotely perform many of the functions that are also available
through the front panel buttons, SIS commands, and/or the
Windows-based control software. The AVT responds to
commands from the AVT 100 Remote as if the corresponding
button were pressed on the front panel, or the corresponding
SIS command or Windows-based control software selection
were entered.

From a distance of no more than 30 feet, the remote control
sends infrared (IR) signals to the AVT 100 through the tuner’s
front panel. The IR receiver is located to the right of the channel
display, but is not visible from in front of the AVT 100.

The infrared remote receiver can receive the signal if it is sent
from within a 40 degree

Software Configuration and Control

The AVT 100 demodulator can be remotely set up and
controlled via a host computer or other device (such as a control
system), attached to the rear panel RS-232 port. See chapter 2,
“Installation and Connection,” for information on connections.
The control device (host) can use the Extron Simple Instruction

Set (SIS

) commands or the Windows-based control software.

Using Simple Instruction Set (SIS™) Commands

Host-to-AVT communications

SIS commands consist of one or more characters per field. No
special characters are required to begin or end a command
sequence. You can enter these commands from your PC using a
communication software program such as HyperTerminal.
When the AVT 100 determines that a command is valid, it
executes the command and sends a response to the host device.

Most responses from the AVT 100 to the host (PC) end with a
carriage return and a line feed (CR/LF = ), which signals the
end of the response character string. A string is one or more
characters.

AVT 100-initiated messages

When a local event such as a front panel selection takes place,
the AVT 100 responds by sending a message to the host,
indicating what selection was entered. No response is required
from the host. One of the following AVT 100-initiated messages
is displayed, depending on your version.

The AVT 100 sends the copyright message when it first powers
on. Vx.xx is the firmware version number.

Error responses

If the AVT 100 is unable to execute a command it receives
because the command is invalid or contains invalid parameters,
the AVT returns an error response to the host. Error response
codes and their descriptions are as follows:

E01 – Invalid input channel number (out of range)
E10 – Invalid command
E11 – Invalid preset
E13 – Invalid value (out of range)

Using the command/response tables

The command/response tables on the following pages list valid
command ASCII and hexadecimal codes, the AVT 100’s
responses to the host, and a description of the command’s
function or the results of executing the command.

The ASCII to HEX conversion table below is for use with the
command/response tables.

Windows®-Based Control/Configuration Software

In addition to the SIS commands, the AVT 100 Windows-based
control/configuration software provides you with another
means of configuring and controlling the AVT 100 via RS-232.

This program includes the functions found on the AVT’s front
panel and the IR remote control, and some additional features
that are available only through the Windows-based software or
the SIS commands.

Compatibility

The software is compatible with Microsoft® Windows 98,
Windows NT, Windows 2000, and Windows XP.

Installing the software

Extron’s AVT 100 Windows-based software program is provided
on a CD with the AVT. You can obtain additional copies of the
software at no extra charge and download updates from the
Extron Web site at http://www.extron.com.

The Windows-based control software program requires a
minimum of 2.5 MB (megabytes) of hard disk space.

To use the software that is on the CD, you must install the
program on your computer. Follow these steps:

1. Insert CD ROM Disk B into your CD drive. The disk

should open automatically. If it does not, double-click
LAUNCH.EXE on the CD to start it.

2. On the “Extron Software Products Disc B:
Issue 2007.x” screen, click the Software
button, shown at right.

3. On the Control Software screen, click the AVT 100’s Install
link (outlined in the illustration on the next page).

Software Installation screen on CD

3. On the File Download window that appears, click Run to

begin installing the program.

If you want to save the installation file
(AVT100Setupv3_n.exe) to your desktop, click Save.

On the Save As window, save the setup file to the desired
location on your computer. When you are ready to
install the software, double-click on the

PAL Format Channels

The table on the following pages lists all the antenna and CATV
channels that are available through the AVT 100 in areas using
the PAL standard.

The AVT 100 display shows only whole numbers; it does not
show decimal fractions. Therefore, when a PAL channel
number is displayed, it does not reflect the exact frequency of
that channel. To find out the exact tuning frequency for a PAL
channel, locate the channel number in the Channel column, then
find its frequency (stated in MHz) beside it in the Freq (MHz)
column.

Example: The frequency for channel 82 is 82.25 MHz.

NTSC Format Channels

The tables on the following pages list all the antenna (TV) and
CATV (cable) channels that are available through the AVT 100
in areas using the NTSC standard (including the US). Tables are
included for four cable channel frequencies: standard, IRC,
HRC, and Japan standard.

The AVT 100 display shows the NTSC channel numbers. To
find out the exact tuning frequency for a channel, locate the
channel number in the Channel column, then find its frequency
(stated in MHz) beside it in the Freq (MHz) column.
