Plug the barrel end into the back of the iC2 Remote. When the power supply has been
properly plugged in, the backlighting for the buttons will flash twice and the charging LED
will turn blue to indicate that the battery is charging. When the battery has a full charge,
the LED will not light. If the charging LED lights red, there is a fault with the battery. If this
happens, unplug the power supply, wait two minutes, and re-plug in the power supply. If
the LED is still red, contact Niles Service Center.
4) CONNECT POWER TO THE HT-MSU. CHECK LED, DISCONNECT POWER
Plug the supplied 12V DC power supply into an unswitched AC outlet. Plug the connector
into the socket marked “Power” on the HT-MSU. If the Power LED does not light, test the
unswitched AC outlet with another appliance. If the outlet tests OK, you have a defective
power supply, which must be replaced for you to continue. Once you have completed
the power supply test, unplug the power supply and continue hooking up the rest of the
wires and cables.
5) CONNECT ALL FLASHERS
Route the connecting wire to the HT-MSU. Connect
the 3.5mm mono plug into the corresponding SRC jack
labeled “IR Output” from the installation worksheet.
If you need to extend the wire, use a 2-conductor 16
gauge or larger (SEE “TECH TIP ON PAGE 15).
6) CONNECT ALL RS232
The RS232 Output jacks use 3.5mm STEREO plug with standard TRS (Tip, Ring and
Sleeve) configuration of Transmit, Receive, and Ground. This may require the installer
to custom make the connection to the corresponding source. Most RS232 controllable
sources use one of the following as its RS232 input connector:
a) A Male DB9 connector
b) A Female DB9 connector
c) A 3.5mm stereo input jack
