SmaRT 218, 918 Remote Control System
✓
Note: The operating frequency for a SmaRT system will be either in the 900 MHz or 2.4 GHz
range. The first number in the system or device name indicates the operating frequency. For
instance, a SmaRT 18-button handheld remote with an ON button and an OFF button will
either be OO-218 or OO-918, where
“2” indicates 2.4 GHz and “9” indicates 900 MHz. As
such, references to the system, handheld remote, and base unit in this manual will use
“x” in
the name (rather than
“2” or “9”) to indicate the operating frequency.
A standard SmaRT x18 Remote Control System consists of a SmaRT OO-x18 18-button
handheld remote control unit and a BU-x16F base unit. A SmaRT system can communicate in
congested radio environments using Direct Sequence Spread Spectrum (DSSS) wireless
technology at a system-dependent 900 MHz or 2.4 GHz range. The system communication link
between the handheld remote control and the base unit is established at the factory using a
process known as
“Association.” The system can also be seamlessly associated in the field—
without the need to open the enclosures of either unit
—by a wireless process described later in
this manual.
The OO-x18 handheld remote has a dedicated ON button and an OFF button. The remaining
sixteen buttons are assigned to and used to control the base unit outputs. The BU-x16F base
unit has sixteen solid state field effect transistor (FET) channels. System configuration is
extended as the input/output (I/O) can also be custom-configured by Cervis Engineering to be
inputs or outputs.
