INSTALLATION CONSIDERATIONS
PLACEMENT OF THE HT-MSU
Niles recommends placing the HT-MSU conveniently close to the equipment it is controlling. Generally, the unit should be placed in a concealed location because its indicator and connections are only used during installation. Placement possibilities include:
1)Wall-mount (affixed to the back of the equipment cabinet or a nearby wall) (Figure 5)
2)Rack-mount (attached to the back of a professional
19-inch standard equipment rack that uses traditional 1, 2 or 3 “u” hole spacing (e.g. Middle Atlantic)
3)Table-top (on the floor or shelf behind the equipment)

WIRING CONSIDERATIONS
The HT-MSU requires several different types of wires runs:
1)IR Sensor Wire: The HT-MSU has an infrared (IR) sensor input for connection to any type of Niles IR sensor. Niles IR sensors utilize 4-conductor wiring and have been designed for use with CAT-5 cable (4-pair twisted) (Figure 6).
2)Flasher Cable: Niles infrared flashers (not supplied with the IC2 System) include
a 10 foot cable. Flasher wires can be extended up to 200 feet using 2-conductor 22 gauge (“zip-cord”). Shielding is not necessary
for a flasher.
3)RS232 Cable: The HT-MSU can control home theater sources using one-way RS232 control cable. Niles does not supply RS232 cables. Home theater sources that are RS232 control capable will usually supply or recommend the wire
and the pin-out that will control their devices. Traditionally, RS232 one-way communication can be sent over three wires (transmit, receive and ground), but not for very long distances. (Niles recommends placing the HT-MSU in close proximity to the sources it
is controlling.)
