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.

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
.
