ISM4 INSTALLATION & PROGRAMMING MANUAL
13
INSTALLATION
The ISM4 should be installed in the same general location as the system A/V components (A/V Receiver, Multi-
Zone Controller, DVD, SAT, etc). Xantech SM Series Sensor Cables are approximately 6 feet in length and
Xantech IR Emitter wires are approximately 10 feet in length, so plan the ISM4 location relative to the other
equipment accordingly. The ISM4 does not generate any critical amount of heat and does not need any special
consideration in terms of ventilation but proper precautions should always be taken to assure the free flow of air
through and around system components to avoid damage. The ISM4 can be placed on a shelf in an equipment
rack or closet or placed directly on top of a system device. It is suggested however, that the ISM4 not be placed
directly on top of a device that generates high levels of heat to protect the ISM4 circuitry and longevity.
CONNECTIONS
ISM4 connections are fairly simple. The most important factor is keeping the wiring consistent by source. That
means be sure the device connected to the Source 1 “Sense In” is the same device attached to the Source 1 IR
Emitter. Labeling the Sensor and Emitter Wires as Source 1, 2, 3, 4 or by specific brand/device (Denon Receiver,
Toshiba DVD, etc) will help in avoiding connection errors and assist in troubleshooting, if necessary. There are
many possible connection schemes for ISM4 controlled systems. For the purpose of the following discussions, the
systems in Figures 4 and 6 will be used. Also note that Xantech manufactures a full line of Sensor Modules
including: Audio (SMAUD01), Video (SMVID01), Magnetic/Current (SMMAG01), LED/Light (SMLIT01), Contact
Closure (SMCC01) and Voltage (SMVLT01) for additional application flexibility of the ISM4.
HOME THEATER SYSTEM (Figure 4)
ISM4
1. Plug the included 12VDC Power Supply 2.1mm coaxial plug into the Power Jack on the ISM4 Rear Panel.
2. Plug the Power Supply into an unswitched AC Outlet.
Source 1 (A/V Receiver)
1. Cut the plug off the end of an unregulated 12VDC Power Supply. (An unregulated power supply’s decay
time, 12V to 0V, is faster than a regulated supply, netting faster system response.) Strip approximately 1/4” off
the jacket and twist the strands so that there are no loose ends that can cause shorts.
2. Connect the stripped ends to the appropriate terminals on the SMVLT01 Sensor. Maintain proper polarity,
typically white stripe (+12V) to the ‘+’ terminal, black wire (GND) to the ‘-‘ terminal.
3. Plug the power supply into a switched AC outlet on the A/V Receiver.
4. Plug the SMVLT01 3.5mm mini plug into the ISM4 Source 1 “Sense In” Jack.
5. Turn the A/V Receiver ON. The SMVLT01 Status LED should illuminate red. (The Source 1 Status LED on
the ISM4 Front Panel should also illuminate solid green. For now, disregard any other front panel LED
activity.)
6. Turn the A/V Receiver OFF. The SMVLT01 Status LED should turn off. If it does not turn off, adjust the
sensitivity to the point where the Status LED turns off. (The Source 1 Status LED on the ISM4 Front Panel
should also turn off. For now, disregard any other front panel LED activity.)
7. Remove the protective backing from an IR Emitter head. Carefully attach the emitter over the IR eye of the
A/V Receiver. If the eye is not obvious, shine a small flashlight into the faceplate to locate it or refer to the
product manual.
8. Carefully pull the emitter wire to the back of the A/V Receiver and over to where the ISM4 is located. Be
careful not to pinch the wire between components.
9. Plug the Emitter 3.5mm mini plug into the ISM4 Source 1 “IR Out “Jack.
10. Label the sensor and emitter wires for reference.
Source 2 (DVD Player)
1. Using a shielded male to male RCA-RCA video cable (Composite Video Cable) with gold ends, connect the
Composite Video Output of the DVD Player to the SMVID01 RCA sensor head.
