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.

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).

Selecting the display aspect ratio

The Display Type submenu lets you select the aspect ratio of the output monitor. The
available selections are 16x9 (the default) and 4x3. From the Display Type submenu, rotate
either Adjustment knob until the desired aspect ratio is displayed.

Selecting the display mode

The Display Mode submenu lets you select the appearance of the image on the display
screen. The options are:

• FILL — The image fills a 16x9 screen. If the video image is 4x3, it is stretched

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.

The figure on the next page shows how the display appears in each mode for the two
display formats.
