Definitions/Notes
Associate
SmaRT configuration method using a series of specific remote unit button presses to
establish a communication link between a SmaRT handheld and a SmaRT base unit.
CAN
Controller Area Network: a standard high-speed serial network interface used in a variety
of industrial and vehicular applications.
DSSS
Direct Sequence Spread Spectrum; an advanced wireless communication technology.
Disassociate/Dissociate
Dissolution of all established communication links between handhelds and a base unit.
IP65
IEC (International Electrotechnical Commission) rating that classifies the level of
protection that an enclosure provides.
IP (international protection)
6 (dust tight)
5 (water jetted from any direction on the enclosure shall have no harmful effects)
PTO
Push to Operate: Command broadcast only while a button is depressed. The command
ends when the button is released.
BU-xH6R
Base unit with six relay outputs controlled by a SmaRT handheld remote. Each SmaRT
BU-xH6R can communicate with up to eight handhelds.
SmaRT 9nn or 2nn Remote Control System
SmaRT system consisting of one SmaRT base unit and from one to eight SmaRT remote
control units. The system operates in the 900MHz range (9nn) or 2.4GHz (2nn) and has
some defined number (nn) of outputs.
For instance, a SmaRT 904 Remote Control System operates in the 900MHz range, and
the remote can control a maximum of four outputs.
Line of Sight (aka Direct-Line-of-Sight)
Type of communication between transceivers
—or a transmitter and a receiver—where the
pathway between the two units must be clear of obstacles.
TX/RX
Transmit/Receive
MOV (Metal Oxide Varister)
Discrete electronic component commonly used to divert excessive current. A protection
device used to suppress noise that can have an undesired effect on equipment and
systems.
Snubber (Snubber Circuit)
Electrical circuit used to suppress electrical spikes (transients) by diverting excess current
around the protected device.
RS-232
Low-speed serial interface used for base unit configuration.
