Tarts Basic Control User
’s Guide (12/14)
When this property is FALSE, the device will listen for commands continuously, consuming power constantly. If an
application is such that it needs Tarts Basic Control to react immediately to things, use this mode. However, you will
need to power the Basic Control unit with a 3.0 – 3.3 VDC power adapter.
Led Mode:
The LED (light) indicates if the switch is closed (ON) or open (OFF). Since the LED will burn power, the user
has the following mode options.
ALWAYS_OFF, ALWAYS_ON, FLASH_WITH_POLL
Poll interval
: the poll interval defines how often the unit checks with the gateway for urgent controls commands (such as
opening or closing its switch). This interval is typically less than the report interval, but never greater than it. The report
interval is critical in the amount of delay that is acceptable for the unit reacting to a command to go open or closed,
when the device is in
Low Power Mode
. It is ignored when the device is not in Low Power Mode.
Send Control:
When sending the command, the user can tell the switch to go open, go closed or toggle (switch to the
opposite state). The user can optionally set a time-duration in seconds for how long this condition should be applied, or
the user can send a zero (0) for the change to remain indefinitely (until another command is sent or until the device is
power cycled).
