Near Intersection of I-35 & I-90 Southern Mn. | As you are aware the Ag Leader Application Rate Module can be used in various ways. One way is to setup an appropriate configuration in the Ag Leader display and use an implement switch. The setup allows the display to map when the switch is open or closed. Instead of an actual implement switch a 12V SPST automotive relay that is triggered by some other device can be used to start/stop the mapping.
A second use of the Application Rate module is to connect it to a flow meter or shaft sensor that produces "shorting" pulses. Again a configuration is created. This configuration will ask for a calibration number so the system is able to convert the pulses created by the flow meter or shaft sensor into familiar units such as gallons. This allows the system to display the applied rate as well as other totals (area, total volume etc.). The system makes a Coverage and an As applied rate map from the information.
I use an Application Rate module this way on our corn planter to monitor (not control) the starter fertilizer delivered by a ground driven fertilizer pump. We rarely change the applied rate but if we should want to do so, we would adjust the stroke of the ground driven fertilizer pump.
We use another Application Rate module with a Nuhn Manure Wagon for liquid hog manure. The Nuhn has a Yamatake mag meter on it. The Yamatake produces a pulse output. Again a configuration is created including a meter cal to convert the pulses produced by the Yamatake into gallons. The operator can observe the applied rate and make adjustments in an attempt to apply the desired rate.
In neither case does the Application Rate Module have the ability to control the rate, it only monitors, displays the rate and creates maps.
Basically any thing that can "short the signal wire to ground" based on flow could be used. It may be necessary to utilize a pullup resistor on the signal line to assure that the signal line crisply returns to a logic "High" between pulses. This may or may not be necessary depending on the flow meter or shaft sensor being used. Raven flow meters for example have a built in Pullup Resistor so no external one is necessary. Other flow meters or shaft sensor may not but an external pullup resistor is easy to install.
Ag Leader makes a stub cable that plugs into the Application Rate Module and has branches for an implement switch and another branch for a flow meter or shaft sensor. I made my own since I have access to the Deutsch plugs/pins etc. that are necessary.
A third use of the Application Rate Module is to connect it to a third party controller (Raven 440 etc.) that has a serial connector. The two devices exchange information. The Raven still controls the application rate but the Ag Leader can create various totals and maps. Auto swath is not an option with this arrangement.
The Application Rate Module can be very useful in these situations. It appears that the newest GO displays do not support it however.

AL app rate module inputs?
