BaseStation 3200 Advanced Irrigation Controller Manual
Glossary of Terms
address When a device is connected to the two-wire, the device is given an address
that identifies it to the BaseStation 3200 controller. The controller refers to
an address as a “zone number.”
air temperature
sensor
A sensor that functions like thermometer to measure the temperature of
the air and report this measurement to the controller by way of a biCoder
application rate The rate at which water is applied to an area within the landscape by an
irrigation system. In order to determine proper duration of watering, it is
essential that you know the application rate for each watering zone.
auto-calibration The controller is able to determine the water holding capacity (field
capacity) of soil when using biSensor based watering strategies. A single
calibration cycle, or automatic monthly calibration cycles can be scheduled.
biCoder™ This is Baseline’s term for several types of two-wire devices. A Baseline valve
decoder is referred to as a valve biCoder. Baseline decoders are called
biCoders because they are capable of full, bidirectional communications,
which enables biCoders to report back to the controller with specific
information, including valve solenoid current and voltage, two-wire
communications health and voltage, and other rich diagnostics information.
biLine™
protocol
Baseline’s proprietary two-way communication standard that operates over
two-wire irrigation wiring
biSensor™ Baseline’s patented digital Time Domain Transmission (TDT) soil moisture
sensor
concurrent
zones
The number of zones (valves) that can be operated at the same time –
typically limited by the amount of water available and the design flow of
each of the zones. Set up the concurrent zones on a per program basis and
have it automatically managed using a flow device.
decoder A two-wire device that can actuate a valve when the controller sends a
message to do so
design flow The GPM that is expected for a zone or the capacity of a mainline, based on
the physical components and topology used in construction
distribution The precipitation rate for different areas of the landscape based on head
types, spacing, layout topology, pressure, etc. Having a uniform distribution
is very important.
distribution
uniformity (DU)
A measure of how evenly a sprinkler system applies water to any specific
zone or area. High distribution uniformity means that the measured
precipitation rate at any point in a zone will be roughly the same. Low
distribution uniformity means that some areas get much more water per
minute of water time than others.
