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.
Introduction, cont’d Mono audio — Can be selected by SIS commands or the Windows-based control software. When Mono is disabled (the factory default), stereo reception is enabled. Front panel security lockout (executive mode) — Locks out users from all front panel functions. Executive mode can be enabled via SIS commands or the Windows-based control software. IR remote access On/Off — Locks out users from controlling the AVT 100 through the IR remote control.
Installation and Connection Mounting the AVT 100 The AVT 100 demodulator can be set on a table or mounted on a rack shelf. Rack mounting procedure To rack mount the AVT, 1. Tabletop use If feet were previously installed on the bottom of the AVT 100, remove them. 1U Universal Rack Shelf Four self-adhesive rubber feet are included with the AVT 100. For tabletop use, attach one foot at each corner on the bottom surface of the unit, and place the unit in the desired location.
Installation and Connection, cont’d Rear Panel Features The following figure shows the switches and connectors on the rear panel of the AVT 100. 8 RF POWER VID A RS-232 / IR Tx Rx 2 3 AUDIO L Tie Wrap R 4 5 Ridges SECTION A–A Power connector — Plug the external 12 VDC power supply into this 2-pin, 3.5 mm captive screw connector. The power supply is included with the unit. The figure on the next page shows how to wire the connector.
Installation and Connection, cont’d C 6 Connect the sleeve to ground ( ). Connecting the sleeve to a negative (–) terminal will damage the audio output circuits. RS-232/IR connector — Use this five-pole connector for an RS-232 connection to a PC for entering SIS commands and using the Windows-based control software, and/or for connecting the wired IR Link. See “Wiring and Connecting the RS-232 Cable,” on the next page, for information on connecting to this port.
Installation and Connection, cont’d 5. Plug the other end of the cable into the RS-232/IR port on the rear panel of the AVT 100. C Do not connect more than one IR Link (either in parallel or in series) to a demodulator. RF POWER VID You can hard wire an MLC MediaLink™ Controller’s modulated IR output connector directly to the AVT 100 to provide remote control of the AVT. RS-232 / IR Tx Rx 150' (45 m) maximum IR +12 Follow these steps to connect the AVT 100 to an MLC.

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 TV/CABLE TUNER 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.
Operation, cont’d When executive mode is disabled, the AVT 100 displays the UNL (Unlocked) message: 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.
Operation, cont’d • • L-R — Select the left input channel for left output and the right input channel for right output. AVT 100 TV/CABLE TUNER R-L — Select the right input channel for left output and the left input channel for right output. CHANNEL (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.
Operation, cont’d Buttons on the AVT 100 IR Remote Control 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. The following functions are available through the buttons on the AVT 100 Remote Control.
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.
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.
