Control Connections

Ethernet Connection

When you connect a computer to the AVT 200HD LAN port, it is vital that you use the
correct Ethernet cables, and that they are properly terminated with the correct pinout.
Ethernet links use Category (CAT) 5 or 5e unshielded twisted pair (UTP) cables, terminated
with RJ-45 connectors. Ethernet cables are limited to a length of 328 feet (100 m).

NOTES: • Do not use standard telephone cables. Telephone cables do not support

Ethernet or Fast Ethernet.

• Do not stretch or bend the cables, because this can cause transmission errors.

The cable that you use depends on your network speed. The tuner supports both

10 Mbps (10Base-T — Ethernet) and 100 Mbps (100Base-T — Fast Ethernet),
half-duplex and full-duplex, Ethernet connections.

• 10Base-T Ethernet requires CAT 3 UTP or STP cable at minimum.

• 100Base-T Fast Ethernet requires CAT 5e UTP or STP cable at minimum.

The Ethernet cable must be properly terminated for your application as either a

crossover or a straight-through cable.

• Crossover cable — Direct connection between the computer and the AVT 200HD

• Patch (straight-through) cable — Connection of the AVT to an Ethernet LAN

Wiring for RS-232 Control

To connect your computer or control system to the AVT RS-232 connector, use an Extron
Universal Control cable (UC50' or UC100'; see “Cables” in the “Reference Information”
section for part numbers) or other female 9-pin-to-bare-wire RS-232 cable.

1. Wire the unterminated end of the RS-232 cable to the 5-pole captive screw connector,

provided with the AVT. Use only the first three pins on the connector, starting from the

left:

a. Connect the transmit wire to the first pin on the left, which plugs into the Tx

(Transmit) port.

b. Connect the receive wire to the second pin, which plugs into the Rx (Receive) port.

c. Connect the ground wire to the third pin, which plugs into the ground port, marked

with _.

Wiring for IR Control

You can control the AVT 200HD by pointing the IR remote control at the front panel IR

sensor and pressing the desired button (see “Using the AVT 200HD IR Remote Control”

in the “Operation” section for more information). However, if the AVT is located where its

IR sensor is not in direct line of sight of the remote control, you can connect an IR Link to

enable the IR signal from the remote control to reach the AVT.

Wiring the IR Link

The optional IR Link Infrared Signal Repeater can be connected directly to an AVT 200HD. To
wire the IR Link for use with the AVT 200HD:

1. Prepare the site and install a wall box, following the directions in the IR Link user guide,

provided with the IR Link equipment.

2. Cut a length of 150 feet (45 m) or less of Extron Comm-Link (CTL or CTLP) cable to go

between the AVT and the IR Link.

3. Attach a 3.5 mm, 5-pole captive screw plug (provided) to each end of the cable. Only

three wires (between pins A, B, and D on the IR Link end, and the ground, IR, and
+12 V pins of the AVT 200HD RS-232/IR connector) are used. Wire the cable as shown

below. Connectors are included with the IR Link, but the cable is purchased separately
(see “Cables” in the “Reference Information” section for cable part numbers).

4. Plug the 5-pole connector into one of the IR Link communication connectors.

5. Connect the other end of the cable to the RS-232/IR port on the AVT rear panel.

AVT 200HD Tuner • Operation 14

Powering On

Apply power by connecting the provided IEC power cord to the rear panel IEC connector
and to an AC source. The tuner performs a self-test that flashes the three TV format

indicators in order from top to bottom and then turns them off while the initial two

power-up screens are displayed in the LCD screen. At the completion of the self-test, the LED
display shows the current channel, the appropriate TV format LED is lit, and the LCD window

displays the default screen cycle.

If an error occurs during the self-test, the AVT locks up and does not operate. If this
occurs, call the Extron S3 Sales & Technical Support Hotline. See the rear cover for contact

information in your area.

When power is first applied to the AVT, the LCD screen displays Extron Electronics, then

AVT 200HD with the current firmware version. If the AVT self-test completes successfully, the

default cycle begins, in which the display alternates between a screen showing the current

output resolution and refresh rates and a screen showing the channel to which the AVT is

currently tuned. These two screens continue to cycle on the screen when the menu system is
not in use.

NOTE: Audio and video mute settings are not retained when power is cycled to the

AV T.

Channels with long minor numbers

Most cable channel numbers do not exceed 5 digits including both major (preceding the

decimal point) and minor (following the decimal point) numbers. However, some cable

channels that do not have virtual channel numbers assigned may have 3- or 5-digit minor

numbers, making those numbers too large to be displayed on the LED panel. For these
numbers, the LED display shows only the last two digits of the minor number, followed by

an additional dot.

In the example below, the cable channel number is 128.25018. For this channel, the LED
display shows the major number (128) and only the last two digits of the minor number
(18). This number is followed by a red dot at the end, indicating that the displayed channel

number is a partial one.

• Tune mode: In tune mode, the Up (>) and Down (<) buttons increment and

decrement the channel number 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 default.

In this mode, you can also do the following:

• Scan for available channels and save them to memory (see “Scanning for

channels,” earlier in this section).

• Save (associate a channel with) a preset. You can do this using SIS commands, the

AVT 200HD IR Remote Control, the HTML (web) pages, or the Windows-based

control software. You cannot save a preset from the front panel.

AVT 200HD Tuner • Operation 21

• Preset mode: In preset mode, the Up and Down buttons step up or down through

presets that have been saved.

NOTE: Using the front panel, SIS commands, the Windows-based control software,

the HTML pages, or the IR Remote Control, you can recall presets in tune

mode and preset mode.

To switch between tune and preset modes:

1. From the Output Configuration menu, press Next repeatedly until the LCD screen

displays Tuner Mode.

2. Rotate either Adjustment knob to select Tune or Preset.

Selecting a channel

To tune to a channel, the AVT 200HD must be in tune mode.
You can tune using either of the following methods:

• Press the Up or Down button to tune to the desired channel. The current channel

number is displayed in the LED display and on one of the default cycle screens.

• Press and hold the Up or Down button to cycle rapidly through the channel numbers.

When the highest channel number available is reached, the display restarts numbering

at the lowest channel number.

If the AVT 200HD is in preset mode, you can tune only to a preset channel. To change

preset channels, press the Up or Down button to display the numbers of the programmed
presets in ascending or descending order in the LED and LCD displays.

If you rerun a channel scan and any different channels are found on the second scan, the
channel and preset lists are updated automatically to add new detected channels or remove

channels that are no longer available. (To scan for channels, the AVT must be in tune mode.)

If the signal for a channel becomes too weak to be detected, the video output screen
displays a “No Signal” message.

Saving presets (Not available via the front panel)

The AVT 200HD allows 198 programmable presets: 99 for over-the-air and 99 for cable. You

cannot save a preset using the front panel menu system; you can only recall one. You can
save a preset using the following methods:

• SIS commands (see the Presets commands in the Command/Response

Table for AVT 200HD SIS Commands, located in the “Remote Configuration

and Control” section)

• The AVT 200HD Remote Control (see “Using the AVT 200HD IR Remote

Control,” later in this section)

• The Tuner Settings web page (see “Saving a preset” in the “HTML

Configuration and Control” section)

• The Windows-based configuration and control software (see the program help)

Only channels that have been found by a channel scan can be saved as presets (see
“Scanning for channels,” earlier in this section).

When a preset is saved, the system gives it the default name “Presetnn,” where nn is the
preset number (for example, Preset01). You can change this name using the four methods

listed above. A preset can have up to 10 characters.
You can also overwrite a preset and save a different channel to its number by using one of

the four methods listed above.

AVT 200HD Tuner • Operation 22

Recalling presets

When a channel is saved as a preset, you can tune to that channel by selecting its preset.
Using the front panel menus, you can recall a preset that has been saved.

When you select a preset, it recalls the cable or over-the-air TV channel that was

programmed for it.

NOTE: Channel presets that are programmed while the AVT is in either over-the-air or

CATV mode remain exclusive to the mode in which they were saved.

To recall (select and tune to) a preset channel from the front panel:

1. Place the AVT in preset mode.

2. Press the Up (>) or Down (<) button repeatedly until the desired preset number is

displayed on the LED panel.

• If no presets have been saved, the LED display flashes “P 0 0” for 2 seconds,

then returns to the currently selected channel number (or to 0.0 if no channel scan

has been performed).

• If presets have been saved, the currently selected preset number is displayed

for 2 seconds, then the channel number associated with the selected preset is

displayed. The LCD screen displays the preset number (or name, if you defined one
using the control software or SIS commands), along with the channel name and
number.

Example: If preset 30 is selected via the Up or Down button in Preset mode, the
LED and LCD displays show the following:

PRESET30
AIR 28–1

After 2 seconds, the digital display shows the channel number (28.1 in this example)
associated with preset number 30.

In addition to the front panel buttons, you can use SIS commands (see the “Remote

Configuration and Control” section); the control software (see the AVT 200HD control
program help file); the AVT 200HD web pages (see “HTML Configuration and Control”),

or the IR remote control buttons (see “Using the AVT 200HD IR Remote Control,” later in
this section) to recall presets.

Selecting the output resolution and refresh rate

The following table shows the available resolutions for each video output type. The refresh

rate is fixed for each resolution. Multiple output devices can be connected to the AVT if their

resolutions are the same. Output sync polarity can be changed by an SIS command (see the

Set output polarity command in the “Remote Configuration and Control” section) or via

the control software (see the control program help file).

horizontally to fit the larger screen.

• FOLLOW (default) — The aspect ratio of the output image follows that of the source (also

called “normal” mode).

A 4x3 video image is framed to a 16x9 display area, retaining its original aspect ratio but
with vertical black bars on both sides of the screen. A 16x9 image is framed to a 4x3

area, with its original aspect ratio but with horizontal black bars at the top and bottom
of the screen.

• ZOOM — The image is evenly stretched both horizontally and vertically, until the picture

fills the entire width of the screen.

Using the AVT 200HD IR Remote Control

The optional hand-held AVT 200HD IR Remote Control lets you remotely perform many

of the functions that are also available through the front panel, SIS commands, the

Windows-based control software, or the embedded web pages. The AVT responds to

commands from the remote control as if the corresponding front panel button were pressed
or the corresponding SIS command or software selection were entered.

From a distance of no more than 30 feet (9.1 m), the remote control sends infrared (IR)
signals to the AVT 200HD through the infrared remote sensor, located on the front panel
to the left of the LED channel display. The IR sensor can receive the signal if it is sent from
within a 40 degree arc to the right or left of direct line of sight between the remote control
and the AVT receiver. See the diagram on the next page.

Selecting a Channel or Preset Using the IR Remote Control

To select or change a channel or preset using the AVT 200HD IR Remote Control:

1. Using the channel selection number buttons, enter each digit of the desired channel or

preset number. For channel selection, use the hyphen (–) button to indicate the decimal
point separating the minor numbers from the major numbers.

Example: To select channel 53.4, press the buttons numbered 5, then 3, then –,
then 4.

The front panel LED display shows the following:

• In tune mode: The channel numbers you pressed, aligned with the left edge of the

field

• In preset mode: The letter P followed by the preset number you pressed, aligned

with the left edge of the field (see the example on the next page).

AVT 200HD Tuner • Operation 35

2. Press the Enter button to implement the channel or preset selection.

• If the number you entered is a valid channel or an existing preset number, the AVT

The AVT 200HD provides a translucent on-screen display (OSD) on which you can view

program information for the current channel or the volume level.

NOTE: The OSD screens are for viewing only. You cannot make selections from them.

Introductory Display

Whenever you change a channel, a translucent display pops up on the television screen,

showing the following information:

• Channel number

• Channel name

• Program title

• Time of day

• Signal strength

This same display appears when you power on the AVT if it is connected to a display that
is already powered on. You cannot disable this introductory display. After approximately

5 seconds, the display disappears.

AVT 200HD Tuner • Operation 36

In the example on below, the current channel is 4.1 (on the OSD, the decimal point is shown

as a hyphen); the channel name is NBC–4LA; the title of the program currently running is

“Today”; the time is 1:37 pm; and the signal strength (shown by a vertical bar graph above
the time) is medium.

Figure 30. Introductory Channel Display Example

Channel Information Display

The channel information display is a translucent window similar to the introductory channel
display. It contains all the information that is in the introductory display plus the channel
resolution, the language in which the current program is being broadcast, the program

rating (G, TV-PG, TV-14, and so on), and whether or not closed captioning is on.
You can enable the OSD displays using the IR remote control (see the ”j Info“ button

description under “Buttons on the AVT 200HD IR Remote Control,” earlier in this section),
the configuration and control software (see the program help file), or SIS commands (see
the “On-screen display (OSD)” commands in the “Remote Configuration and Control”
section). The channel information is displayed for approximately 3 seconds, then the window
closes.

In the following example (read left to right), the current channel is 5.1; the channel name
is KTLA-DT; the broadcast resolution is 1080i; the signal strength is medium, the program
being broadcast is “Jerry Springer”; the time is 1:45 pm; the program is in English; closed
captioning (CC) is enabled, and the program rating is TV-14.

Figure 31. Channel Information Display Example

Volume Level Display

Whenever the volume is adjusted by any method, the volume level display is shown on the

screen for approximately 3 seconds.

Figure 32. Volume Level Display on the OSD

Unlike the volume display on the LCD screen, this on-screen display shows the volume
increase or decrease in increments of 5% (20 steps). (Volume adjustments that are made

using the front panel knob, the communication and control software, or SIS commands are

displayed in the LCD window and on the computer screen in 1% increments [100 steps].)

AVT 200HD Tuner • Operation 38

Remote Configuration and Control

This section describes the serial, Ethernet, and USB connections through which the Extron

Simple Instruction Set (SIS) commands can be issued, and lists the commands that are

available for configuring and controlling the AVT 200HD. Topics include:

• Serial Port

• USB Port

• Ethernet Port

• Using SIS Commands

• Accessing the AVT 200HD Control Software

Serial Port

USB Port

Ethernet Port

The AVT supports RS-232 serial communication protocol and can operate at 9600, 19200,
38400, or 115200 baud rates (see “Configuring the serial port and IP parameters” in

the “Operation” section to configure this port using the front panel menus).

The 5-pole shared 3.5 mm captive screw connector labeled RS-232/IR on the rear panel can

be connected to the serial port of a host device such as a computer running a utility such as

the Extron DataViewer or HyperTerminal, an RS-232 capable PDA, or a control system (see

“Wiring for RS-232 Control” in the “Installation” section for information on connecting to
this port).

SIS commands can also be sent through the USB Config port on the AVT front panel, using
Extron DataViewer or another utility that accommodates USB. (see “Connecting to the

USB Port” in the “Installation” section to set up communication via USB).

The RJ-45 connector on the rear panel can be connected to an Ethernet LAN or WAN to
enable SIS control of the AVT. The tuner and the controlling device can communicate via
Extron DataViewer or Telnet (a TCP socket using port 23). The Telnet port number can be

changed, if necessary, via SIS commands (see “Connecting as a Telnet Client” in the
“Reference Information” section for information on connecting via Telnet).

Ethernet Cable

The Ethernet cable must be properly terminated for your application as either a straight-

through cable or a crossover cable (see “Ethernet Connection” in the “Installation”
section for pin assignments for these cables).

AVT 200HD Tuner • Remote Configuration and Control 39

IP Address

To access the AVT 200HD via the Ethernet port, obtain the IP address of the tuner from your

network administrator. If the IP address has been changed to an address comprised of words
and characters, you can determine the actual numeric IP address using the ping (ICMP) utility
(see “IP Addressing” in the “Reference Information” section for more information). If the

IP address has not been changed, the factory-specified default is 192.168.254.254.

Establishing an Ethernet Connection

Establish a network connection to a AVT 200HD as follows:

1. Open a TCP connection to port 23, using the IP address of the tuner. (A variety of

methods are available for making this connection, including Telnet and utilities such as

Extron DataViewer and HyperTerminal).

The tuner responds with a copyright message that includes the date, the name of the
product, firmware version, part number, and the current date and time.

NOTE: If the tuner is not password-protected, the device is ready to accept SIS

commands immediately after it sends the copyright message.

If the tuner is password-protected, a password prompt appears below the
copyright message.

2. If the tuner is password protected, enter the appropriate administrator or user password.

3. If the password is accepted, the tuner responds with Login User or Login

Administrator.

If the password is not accepted, the Password prompt reappears.

Connection Timeouts

The Ethernet link times out after a designated period of no communications. By default, this
timeout value is set to 5 minutes; however, the value can be changed (see the Set current

connection port timeout command in the Command/Response Table for IP-Specific SIS

Commands, later in this section).

NOTE: Extron recommends leaving the default timeout at 5 minutes and periodically

issuing the Query (Q) command to keep the connection active. If there are
long idle periods, Extron recommends disconnecting and reopening the

connection when another command must be sent.

AVT 200HD Tuner • Remote Configuration and Control 40

Using SIS Commands

SIS commands consist of one or more characters per command field. They do not require

any special characters to begin or end the command character sequence. Each tuner

response to an SIS command ends 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.

Tuner-initiated Messages

When a local event such as a front panel operation occurs, the tuner responds by sending a

message to the host. The tuner-initiated messages are listed below (underlined).

• Copyright message

With an RS-232 connection:

(c) Copyright 2011, Extron Electronics AVT 200HD, Vx.xx, 60-770-01

With an Ethernet connection:

(c) Copyright 2011, Extron Electronics, AVT 200HD, Vx.xx, 60-770-01

Ddd, DD Mmm YYYY HH:MM:SS

The tuner initiates the copyright message when it is first powered on or when an IP
is established. Vx.xx is the firmware version number. With the Ethernet connection, a
carriage return and the date and time are added to the copyright message.

This message is not displayed with a USB connection.

]

•

Password:

The tuner initiates the password message immediately after the copyright message
when the controlling system is connected using TCP/IP or Telnet and the tuner is
password protected. This message means that the tuner requires an administrator or
user level password before it will respond to the commands entered via this link.

The unit responds with one of the following messages, depending on the password that
was entered:

]

•

Login Administrator

]

Login User

The tuner initiates the login message when a correct administrator or user password has
been entered. If the user and administrator passwords are the same, the tuner defaults
to administrator privileges.

]

]

]

]

]

NOTE: The Password prompt is redisplayed if an incorrect password is entered.

TunerReady

After a unit reset or an output resolution change, the tuner sends this message to
indicate the reset is complete.

]

V-chip Security for Parental Control

In addition to passwords for administrators and users, a V-chip personal identification
number (PIN) is required to access and view parental control settings. With this PIN, you can
view and change these settings when logged in at either the administrator or user level. You

can set or change this password using SIS commands.

AVT 200HD Tuner • Remote Configuration and Control 41

Tuner Error Responses

Space

If the AVT is unable to perform an SIS command that it receives because the command
is invalid or contains invalid parameters, the tuner returns an error response to the host.

AVT 200HD Tuner • Remote Configuration and Control 73

HTML Configuration and Control

This section provides procedures for accessing and using the AVT embedded web pages. The

following topics are included:

• Accessing the Web Pages

• Special Characters

• System Status Page

• Configuration Pages

• File Management Page

• Control Pages

The AVT can be controlled and operated through its Ethernet port, connected via a LAN or
WAN and using a web browser such as Microsoft Internet Explorer®. The browser displays
the AVT web pages, which provide an alternative means of configuring and operating

the tuner. These factory-installed web pages are always available and cannot be erased or
overwritten.

NOTE: If your Ethernet connection to the tuner is unstable, try turning off the proxy

server in your web browser. To do this in Microsoft Internet Explorer, click

Tools > Internet Options > Connections > LAN Settings, clear the Use a
proxy server... check box, then click OK.

Accessing the Web Pages

Access the HTML pages as follows:

1. Start the web browser program.

2. Click in the browser Address field and enter the IP address of your AVT.

NOTE: If the local system administrators have not changed the value, use the

factory-specified default 192.168.254.254 in this field.

3. If you want the browser to display a page other than the default page (such as a custom

page that you have uploaded), enter a slash (/) following the IP address and the name of
the file to open.

NOTE: The browser Address field should display the IP address in the following

format: nnn.nnn.nnn.nnn/optional_file_name.html.

AVT 200HD Tuner • HTML Configuration and Control 74

4. Press the <Enter> key. The tuner checks to see if it is password protected.

• If the tuner is not password protected, the System Status web page opens.

• If the AVT is password protected, the network password dialog box is displayed.

Figure 46. Example of a Network Password Dialog Box

5. If an administrator or user password is required, enter it in the Password field. If

desired, select the check box to have the system input your password the next time you
enter your AVT IP address. Click OK.

Special Characters

The HTML language reserves certain characters for specific functions. The AVT does not

accept these characters as part of preset names, the tuner name, passwords, or locally
created file names.

The following characters are invalid or not recommended:

+ ~ , @ = ` [ ] { } < > ’ ‘ “ ” ; : | \ ? and space.

NOTE: A User name entry is not required.

The AVT 200HD checks several possibilities, in the following order, and then responds

accordingly:

• If the address includes a specific file name, such as 10.13.156.10/

file_name.html, the tuner downloads that HTML page.

• If there is a file in the AVT memory that is named “index.html,” the tuner

downloads “index.html” as the default startup page.

• If neither of the above conditions is true, the tuner downloads the

factory-installed default startup page, “nortxe_index.html,” also known as the
System Status page.

Configuration Pages

The Configuration tab contains enables you to four pages that only an administrator can
access. These pages are listed in the left sidebar menu on the Configuration tab. The
following sections describe the changes you can make from these pages.

System Settings Page

The AVT 200HD displays the System Settings page (shown on the next page) when you

click the Configuration tab. The screen consists of fields in which you can view and
edit IP administration and system settings. The Tuner Settings, Passwords, and Firmware

Upgrade pages can be accessed by clicking the appropriate link on the left sidebar menu.

See “IP Addressing” in the “Reference Information” section for basic information about IP
addresses and subnetting.

Figure 48. System Settings Page

On password-protected connections, there are two levels of protection: administrator and

user. Administrators have full access to all tuning capabilities and editing functions. Users

can select channels, save and recall presets, and view all settings with the exception of
passwords.

• Ethernet connection to the tuner, either entering SIS commands (see the “Using SIS

Commands” section) or using the AVT 200HD Configuration & Control Program (see

the control program help file) is password protected.

• Connection via the RS-232 port is not password protected.

AVT 200HD Tuner • HTML Configuration and Control 77

IP Settings Fields

The IP Settings fields provide a location for viewing and editing settings unique to the
Ethernet interface. After editing any of the settings on this page, click the Submit button at
the bottom of the IP Settings section.

Unit Name field

The Unit Name field contains the name used as the “from” information when the AVT
e-mails notification of its failed or repaired status. You can change this name field to any

valid name, up to 24 alphanumeric characters.

DHCP radio buttons

The DHCP On radio button directs the tuner to ignore any entered IP addresses and to obtain

its IP address from a Dynamic Host Configuration Protocol (DHCP) server (if the network is
DHCP capable).

The DHCP Off radio button turns DHCP off.

Contact your local system administrator for this setting.

IP Address field

The IP Address field contains the IP address of the connected AVT. This address is encoded
in the tuner flash memory.

Valid IP addresses consist of four one-, two-, or three-digit numeric sub-fields separated
by periods. Each field can be numbered from 000 through 255. Leading zeros, up to three
digits total per field, are optional. Values of 256 and above are invalid.

The factory-installed default address is 192.168.254.254, but if this conflicts with other

equipment at your installation, you can change the IP address to any valid value.

NOTE: IP address changes can cause conflicts with other equipment. Only local system

administrators should change IP addresses.

Gateway IP Address field

The Gateway IP Address field identifies the address of the gateway (to the mail server) to
be used if the tuner and the mail server are not on the same subnet.

The gateway IP address has the same validity rules as the system IP address (see “IP Address

field,” above).

Subnet Mask field

The Subnet Mask field is used to determine whether the tuner is on the same subnet as the
mail server when you are using a subnet (see “Subnetting — A Primer” under “Ethernet
Connection” in the “Reference Information” section for more information).

The subnet mask address has the same validity rules as the system IP and gateway IP
addresses.

MAC Address field

The MAC (media access control) address is a unique hardware address by which each

individual AVT can be identified. It consists of six pairs of characters separated by hyphens.
For all Extron products, the first three character pairs are 00-05-A6, followed by three more

pairs unique to the individual device. The MAC address is hard coded in the tuner and
cannot be changed.
