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.

Installation and Connection

Mounting the AVT 100

The AVT 100 demodulator can be set on a table or mounted on a rack shelf.

Tabletop use

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.

Rack mounting

For optional rack mounting, do not install the rubber feet. Mount the AVT 100 on an RSU 129 Universal Rack Shelf Kit (part #60-190-01) or an RSB 129 Basic Rack Shelf (part #60-604-01).

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.

1U Universal Rack Shelf

Both front false faceplates use 2 screws.

Mounting the AVT 100 on a rack shelf

2. Mount the AVT 100 on the rack shelf, using two 4-40 by

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.

C The length of the exposed (stripped) copper wires is

important. The ideal length is 3/16" (5 mm). Longer bare wires can short together. Shorter wires are not as secure in the captive screw connectors and could be pulled out.

C Do not tin the stripped power supply leads before

installing the captive screw connector. Tinned wires are not as secure in the captive screw connectors and could be pulled out.

W Keep the two power cord wires separate while

plugging in the power supply. Remove power before wiring.

To verify the polarity before connection, plug in the power supply with no load and check the output with a voltmeter.

Connecting the AVT 100 to the IR Link

The optional IR Link Infrared Signal Repeater can be connected

directly to an AVT 100. To wire the IR Link for use with your AVT 100,

1. Prepare the site and install a wall box, following the

directions in the IR Link User’s Manual, provided with your IR Link equipment.

2. Cut a length of 150' (45 m) or less of Extron Comm-Link

(CTL or CTLP) cable to go between the AVT 100 and the IR Link.

3. Attach a 3.5 mm, 5-pole captive screw connector to each

end of the cable. Only three wires (between pins A, B, and D on the IR Link end, and pins Ground, IR, and +12 V on the AVT 100 end) are required. Wire the cable as shown in the illustration on the next page. Connectors are included with the IR Link, but the cable must be purchased separately.

4. Plug the 5-pole connector into one of the IR Link’s

communications connectors.

Connecting the AVT 100 to a MediaLink Controller

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.

Follow these steps to connect the AVT 100 to an MLC. See the diagrams on the next page for examples.

1. Cut a length of 150' (45 m) or less of Extron Comm-Link

(CTL or CTLP) cable, which will go between the AVT 100 and the MediaLink controller.

2. Attach the provided 3.5 mm, 5-pole connector to the end of

the cable that will attach to the AVT 100, connecting one wire to the center pin (which will plug into the AVT’s ground connector pin, marked with to the pin to the right of the center ground pin. (This pin will plug into the AVT’s IR connector.) Plug this end of the cable into the RS-232/IR connector on the AVT’s rear panel.

3. On the other (MediaLink controller) end of the cable, do

either of the following:

• Attach the cable’s corresponding wires to the ground and IR output pins of the captive screw connector that will plug into the MLC. Plug this end of the cable into the IR connector on the MLC’s rear panel.

• Attach the cable’s wires directly to the ground and IR output pins on the MLC’s rear panel.

4. Using Global Configurator software, program the MLC

with the proper IR drivers for the AVT 100. Refer to your MediaLink controller user’s manual for more information.

N If the AVT 100 does not respond to commands from the

MediaLink controller, a 1k ohm resistor may be required between the ground and IR pins on the AVT 100.

This resistor is required when you are using an MLC 52 to control the AVT.
