2 Wire Devices
Smart Water Management on the Go
Whether you maintain landscapes or manage facilities, the WeatherTRAK® Mobile app puts control of your smart irrigation system in the palm of your hand. From creating programs for site establishment to wet checks, to regular maintenance, WeatherTRAK Mobile app gets the job done faster and smarter.
The Precip Sensor: Measure it to manage it
Baseline elevates the precipitation sensor, utilizing tipping rain bucket technology, to communicate real-time data across existing 2-wire engineered systems.
You can start, stop, or pause irrigation based on precipitation data through the Baseline 3200 controller. Create easy year-over-year reports to analyze all rainfall events. Set up real-time communication and remote management. Through automation and larger stores of data to work with, you’ll make better decisions about your soil (and your bottom line).
Paired with a soil moisture sensor, the Precip measures effective rainfall. You’ll understand how much rain made it into the soil, as well as rain rate, volume, and frequency. With unmatched precision in the industry, our Tipping Bucket hardware is highly engineered for optimal data accuracy. While the rainfall is unpredictable, your metrics don’t need to be. You’ll have a better grasp on:
- Rate: rain intensity within a defined period (inches per hour)
- Volume: the amount of rain (gallons)
- Frequency: how often a rain event occurs (compared to soil dry-down)
- Effectiveness: total rainfall, actual evapotranspiration, and soil profile
With the Baseline Precip Sensor, you’ll access real-time site conditions as they shift and evolve. Measure the rainfall to measure the savings – in resources, money, and time. The weather changes frequently, but you can keep up using Baseline technology.

biLine™ + biCoders™ = Intelligent Technology
The secret to Baseline’s biLine two-wire technology lies in Baseline’s patented biCoders™ (two-wire decoders). Baseline’s biCoders are the only true bi-directional two-wire devices in the industry because Baseline’s biCoders not only receive commands from the controller, they also send real-time information back to the controller. Plus, Baseline’s biCoders have built-in diagnostic LED lights that tell you at a glance whether the device is working.
This smart technology also enables you to assign any biCoder to a zone or function from the controller after the biCoder has been installed in the field. With a multi-station biCoder, you can assign any station to any zone, in any order. These features will save you hundreds of hours because Baseline has eliminated the need for expensive programming equipment or multiple trips into the field just to assign zones to a device. And diagnostics and repairs are a whole lot easier too.
Baseline’s biLine technology and biCoders can operate up to 15 zones concurrently at distances further from the controller than any other product in the market. More zones running means a shorter water window, and a greater allowable wire length means fewer controllers to manage.
Baseline’s biCoders are available in single, dual, and quad-station configurations. They’re also available for flow and event devices.
Pressure-based Flow Management for the Two-Wire
With the Baseline Pressure biCoder, your BaseStation 3200 irrigation controller is capable of reading a 4-20mA signal over the two-wire. The Pressure biCoder, when configured with a pressure sensor, allows the BaseStation 3200 to start, stop, or pause programming based on PSI readings from the device. You can even shut off pumps or master valves based on high pressure or low pressure alerts.
With the ability to read pressure, you can manage your BaseStation 3200 irrigation system to ensure your valves won’t activate until you have reached the desired PSI and level of flow stabilization.
Shut down a master valve, pump, or hydrometer if pressure is lost in the mainline due to a break. Control the opening or closing-delay between irrigation zones stop a program after the desired pressure is reached.
For more details, refer to the BL-5406 4-20mA biCoder Technical Specification.

Baseline’s biLine™ Protocol and Two-Wire — Features and Specifications
- The biLine II protocol for two-wire operates below 30 VAC RMS
- True two-way communication that uses a 9-byte packet for commands and replies
- Search for and identify all devices connected to the two-wire and list them in the controller
- Address devices by serial number by assigning each zone address a device serial number
- Re-address any device from the controller by re-assigning the device’s serial number to a new zone address
- Any station on a multi-station biCoder can be assigned from the controller to any zone address in any order
- Detect and repair from the controller all address conflicts for devices that are connected to the two-wire
- Automatically detect communication collision on the two-wire and resend any message experiencing an error
