Operation

Front Panel Features

The NTSC and the PAL versions of the AVT 100 have the same front panel with identical components and appearance. The following features and functions are available on the AVT 100 front panel.

AVT 100 front panel

① Digital display — This 3-digit, alphanumeric LED display indicates the antenna TV or CATV channel being received (in Tune mode) or the selected channel preset (in Preset mode).
② IR receiver (not visible from the exterior of the unit) — This sensor receives commands via infrared signals from the optional AVT 100 IR Remote Control.
③ Channel up and down buttons — These push-buttons are used to increment or decrement the channel or preset number. You can also activate Auto-Scan by pressing and holding both of these buttons simultaneously for 2 seconds (see "Initiating Auto-Scan" on the next page).

Using the Control Buttons

Changing the channel

If the AVT 100 is in Tune mode (factory default):

• Press the up or down Channel button to tune to the desired channel. The current channel number is displayed in the 3-digit LED display.
• Press and hold down one of the Channel buttons to change the channels rapidly until the button is released. When the highest channel number available is reached, the display restarts numbering at the lowest channel number.

If the AVT 100 is in Preset mode (available only by SIS command, the Windows-based control software, or the IR remote control), you can change only to a preset channel. To change the preset, press the Channel buttons to display the numbers of the programmed presets in incremental or decremental order.

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 Windows-based 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 following message on the digital display for 2 seconds:

Any attempt to use the front panel buttons while the AVT 100 is in executive mode causes the LOC (Locked) message to flash.

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 Windows-based control software.

NOTE Presels can be recalled via SIS commands, the Windows-based control software, or the AVT 100 Remote in both tune mode and presel 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 Windows-based 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.

	NTSC		NTSC Japan		PAL
DIP Switch	Antenna	Cable Cable	Antenna		Antenna and Cable
Channel #	2 to 69	2 to 125	1 to 62	1 to 63	48 to 885

Channels available for presetting

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.

Operation, cont'd

• L - R — Select the left input channel for left output and the right input channel for right output.
• R - L — Select the right input channel for left output and the left input channel for right output.

(See chapter 4, "Software Configuration and Control," for information on the SIS commands for audio mode selection. To switch audio output modes using the Windows-based control software, refer to the help file.)

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 arc to the right or left of direct line of sight between the remote and the AVT 100 receiver. See the diagram below.

Area for remote signal reception

NOTE The AVT 100 must be plugged in before you operate the remote control. Setup operations cannot be performed from the remote.

Locking IR remote access

The AVT 100 Remote Control can be set to lock out users from using it to control the AVT 100. This remote access can be turned on and off via SIS commands or the Windows-based control software. When remote access is set to Off, all AVT 100 controls remain available through other means (SIS commands, Windows-based control software, and the front panel).

Installing batteries in the AVT 100 Remote

Install two AAA batteries in the AVT 100 Remote Control as shown below.

Buttons on the AVT 100 IR Remote Control

The following functions are available through the buttons on the AVT 100 Remote Control.

Buttons on the AVT 100 Remote Control

① Channel selection (0 through 9) — In tune mode, press these number buttons to specify a channel number, then press Enter to select it.

In preset mode, pressing these buttons also selects the channel whose number(s) you pressed. The buttons do not select preset numbers.

② Channel up/down — Press the up and down arrows on this rocker button to increment and decrement the channel or preset number.

In tune mode, pressing either part of this button displays the adjacent channel number. If an Auto-Scan has been performed, pressing the Channel button causes the display to cycle between the channels that were set by the scan for the mode (TV or cable) in which the scan was done. (In this case, the adjacent channel may not be available for display.)

In Preset mode, the next or previous preset channel is displayed, depending on which part of the button you pressed. The AVT 100 briefly displays the preset number preceded by a "P," then it displays the channel number associated with that preset.

If no presets have been defined when the Channel button is pressed, the display shows "P00," then the channel number to which the AVT 100 was set before entering preset mode.

NOTE The Channel up/down button applies to antenna (TV) and cable modes. Use the DIP switch on the rear panel to switch between these modes.

③ Video Mute — Press this button to toggle video muting on and off. When muting is on, video output is mute.
④ Audio Mute — Press this button to toggle audio muting on and off. When muting is on, audio output is mute.
⑤ Tune — Press this button to switch to tune mode. In tune mode, the Channel buttons switch between channel numbers.
⑥ Preset — Press this button to switch to preset mode. In preset mode, the Channel buttons switch between preset channels.
⑦ Save — After keying in a preset number, press this button to save the currently selected channel as a preset.
⑧ Enter — After keying in a channel number, press this button to switch to that channel.

Selecting a channel (tuning) using the IR remote

To select or change a channel using the AVT 100 IR Remote Control,

1. Using the IR remote channel selection number buttons in the same way you would use the number keys on a calculator, enter the number of the desired channel.

Example: To change to channel 105, press the buttons numbered 1, then 0, then 5.

1. Press the Enter button to activate the channel change. If the number you entered is a valid channel, the AVT 100 switches to it, and the number remains displayed on the AVT 100 front panel.

If you enter an invalid (out of range) channel number, after 3 seconds the front panel display returns to the channel number that was displayed previously and does not change the channel.

Operation, cont'd

Saving a preset using the IR remote

To assign a channel number to one of the 198 available presets,

1. Switch to the channel that you want to assign. (See "Selecting a channel (tuning) using the IR remote," on the previous page.)
2. Enter the preset number to which you want to assign the current channel.
3. Press Save. The AVT 100 saves the preset, and displays "P" and the preset number as confirmation. After 3 seconds, the display returns to the channel number that you just saved.

NOTE If an invalid preset number is entered, no preset is saved.

Software Configuration and Control

Using Simple Instruction Set (SIS™) Commands

Windows®-Based Control Software

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.

NOTE

These messages are displayed only at power-up.

NOTE

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.

Channel Frequencies

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.
