MOUNTING
T
he KX7s is designed for flush-mount, in-wall installations. It requires an available mounting depth of 2 inches (52.5mm) from the surface of the wall.
IMPORTANT NOTE: There is little margin for error when fitting the KX7s into the wall opening.
Make sure to use the included cardboard cut-out template to create the correct size opening in the wall. Additionally, carefully double-check that all
measurements taken using the cardboard cut-out template are accurate.
MOUNTING HEIGHT
The recommended mounting height for the KX7s is between 54 inches (1.37m) and 60 inches (1.52m) from the bottom of the faceplate.
MOUNTING WINGS
Two mounting wings are located on the top and bottom of the KX7s, which can be used to secure the KX7s to drywall in retrofit installations. Place KX7s in
the opening in the wall and tighten the mounting wing screws located on the front of the KX7s (bezel removed).
CONDUIT BOX
For new construction installations a conduit box may be purchased separately from an RTI distributor. For mounting instructions, refer to the conduit box
installation guide
CONNECTIONS
CONTROL PORT
T
he Control Port on the KX7s uses a Cat-5/6 cable with RJ-45 termination. When used in conjunction with an RTI control processor (e.g. RTI XP-6s) and
an RTI connecting block (e.g. RTI CB-8), this port serves as the power source for the KX7s in addition to infrared and RS-485 communication.
ETHERNET PORT
The KX7s is designed for connection to a LAN via Cat-5/6 cabling with RJ-45 termination. Additionally, the KX7s can be optionally powered using Power-
Over-Ethernet, allowing the power to be extended to the KX7s over the same Cat-5/6 cable that carries Ethernet communication. When powering the
KX7s using PoE, a class 3 PoE router or PoE injector must be used.
RS-232
T
he KX7s is capable of direct RS-232 communication using a Cat-5/6 cable with RJ-45 termination. A DB9 - RJ45 adaptor is included with the KX7s.
NOTE: RS-232 communication should be limited to 50 feet (16m) depending on baud rate.

FERRITE RING INSTALLATION
In order to comply with regulatory agency standards for EMI
emissions, the included ferrite ring must be installed on any cable
attached to the KX7s Ethernet Port, Control Port, RS232 Port or
Video Input.
• To open the ferrite ring enclosure pry open the plastic latch.
• Insert cables into the ferrite ring at the end of the cables as
close to the KX7s enclosure as possible.
• Close ferrite ring enclosure until the latch snaps in place.

PROGRAMMING
THE TOUCHSCREEN DISPLAY
The KX7s touchscreen display is programmed using the RTI Integration Designer Programming Software. Normally it is organized into a series of pages
containing objects (buttons, text, graphics, etc.) that are related to each other. For example, they may all display information necessary for controlling a
particular music server.
UPDATING FIRMWARE
It is highly recommended that this and all RTI products have the latest firmware installed. The firmware can be found in the Dealer section of the RTI
website (www.rticorp.com). Install the firmware using a USB cable (USB A to Mini B).
UPDATING SOFTWARE
R
TI’s Integration Designer data files can be downloaded to the KX7s using a USB cable (USB A to Mini B), or via hard-wired or wireless Ethernet. If the KX7s
is hard-wired to a LAN and the router has DHCP enabled, the initial data file can be made over Ethernet.
