INSTALLER GUIDE
UNO-S2 Keypad Connections
CAT-5 Connection
The UNO-S2 Keypad uses a 110-punch-
down terminal to provide a simple
installation and strong connection for
CAT-5 cable’s eight conductors.
Punchdown terminals require the use of
a punchdown tool which has been pro-
vided with the keypad kit. Attach the
CAT-5 cable to the 110-punchdown ter-
minal on the UNO-S2 Keypad as shown,
matching the conductor colors to the
connection color guide. The keypad will
not operate properly if the terminations
deviate from the required connection
order.
Take care when using an impact 110
punchdown tool, as this may overspread
the contact points. Use of the impact tool
may propel stray bits of wire and jacket
into the keypad’s chassis and possibly
cause a short in the circuitry. Gently
shake or blow air through the keypad
chassis to remove stray wire before the
keypad is installed into the junction box.
OS Update Port
The OS Update Port is is used to update
the UNO-S2 Keypad operating system
software in the future. When an update is
released, it will be available online
through the Document Center at
www.russound.com.
Look for the
Technical Documents under Multi-
source/Multi-room products. The
Programming Cable is available from
Russound, Part #2500-121036.
Jumper Setting
The jumper settings on the back of the
UNO-S2 Keypad can be set for “Run” and
“OS Update.” The jumper setting must be
in the “Run” position before the keypad is
mounted into the junction box, and must
remain set in “Run” to operate the key-
pad. The jumper will be set to “OS
Update” only while updating the keypad’s
operating systems.
