INTRODUCTION
INSTALLATION APPLICATIONS
RNET-enabled System
When the ST2S Tuner is used with an RNET-
enabled device such as the CAV6.6 and is con-
nected to it through the Link In or Link Out port,
the tuner will be controlled by the CAV6.6
through the UNO-S2 keypad. Through RNET,
tuner information such as Tuner 1 or 2, station
frequency or channel, preset names and AM/FM
band or SIRIUS is displayed on UNO-S2 keypads.
An additional RNET device can be connected to
an existing ST2 by using the Link Out of the first
unit into the Link In of the second unit.
Before using the ST2S tuner with the
CAV6.6, you must assign source numbers
to Tuner 1 and 2 in the ST2 Setup Menu
AND
complete the CAV6.6’s Source Setup
procedure to identify the tuner as a
“Peripheral“ device and assign Source
Numbers. The CAV6.6 (Rev. 3) requires
firmware version 2.01.16 or higher and
CAV6.6 (Rev. 4) requires firmware version
3.01.10 or higher to control each tuner
through RNET. The UNO-S2 keypad requires
firmware version 3.01.01 or higher.
IR-controlled System
CAi Series -
The ST2S Tuner can be controlled by infrared
commands received through either of the two IR
connections on the rear panel. There are two
unique IR code sets for Tuner 1 and Tuner 2,
which allow each to be controlled independently
from either IR connection. These codes can be
learned from the ST2-RC remote control into the
CA-LRC1 remote control and/or the DSC and
DAN IR learning keypads. The ST2S contains two
individual tuners, which makes it act as two
sources in the CAi system. There are two source
audio outputs and two IR connections - one for
each tuner in the ST2S. You will need at least
one IR link cable (Russound P/N 09-0508) for
these connections (one is supplied with each CAi
system). If you are using an IR-controlled system
from another manufacturer, installation should be
similar. The ST2S IR codes may be learned into
many other manufacturers’ remote controls that
have learning capability for unified control over
the A/V equipment.
Note: Optional ST2-KP keypads can be used to
provide control for the ST2S Tuner and are
designed to be used with IR-controlled systems.
RS-232 Controlled System
The ST2S Tuner can be controlled using the
RNET protocol provided via the RS-232 port on
the rear panel. It can also be controlled by any
RS-232-enabled control system (e.g., Crestron,
AMX). Information on RS-232 operation is avail-
able to dealers on the Russound web site,
