Near Intersection of I-35 & I-90 Southern Mn. | Long story short. 1) I suspect you need an pullup resistor with a proximity sensor. 2) you have not followed the correct path in creating the configuration for your situation.
Personally I use an App Rate Module to monitor (not control) starter fertilizer on my planter. I do not need a pullup resistor since my Raven flow meter has one built in.
Now the long story.
The App Rate module can be used in a variety of ways:
1) Watch an implement switch to start/stop a Coverage map. This is just a coverage map and has no reference to the quantity of product being applied.
2) Watch a flow meter or shaft sensor to start/stop an Applied Rate Map. In this mode, the App Rate module watches for and counts the pulses produced by the flow meter or shaft sensor and by use of a calibration number converts those pulses into familiar units such as gallons or pounds. The total volume, area and rate/acre are displayed as well an "as applied" map.
3) Use a special serial cable to communicate with a third party controller such as a Raven 440 or the like.
I use method #2 to monitor but not control the rate of starter fertilizer applied with a ground driven pump on my corn planter. The App Rate module displays the applied rate, acres etc. as well as creating an applied map.
I assume this is your goal. Since you will be using a shaft sensor rather than a flow meter, your calibration number will be dependent on the gate setting, product density and other factors.
I believe you are not following the correct path in setting up your InCommand. It sounds as if you have taken the route to setup a configuration for situation #1.
The correct path will ask you various questions, one of which will be the calibration number for your sensor. You will need to determine this yourself as it will depend on several factors. As far as a speed source leave it as the default of using GPS speed.
Another consideration is that when I've worked with proximity sensors it was necessary to wire in a pullup resistor on the signal wire. This is not necessary with a Raven flow meter since the circuitry inside the Raven flow meters handles this. To wire in a pullup resistor is fairly easy. It amounts to connecting a resistor between power to the flow meter and the signal wire. In mechanical terms this acts as a "spring" which attempts to keep the signal wire at the power voltage level. When the shaft turns a bit, the proximity sensor temporarily shorts the signal wire to ground but then releases the signal wire as the shaft turns a bit further. The idea is that this creates a series of distinct pulses that vary between the voltage of the power wire and ground. The circuitry in the Application Rate Monitor watches for those pulses. It counts the pulses and uses the meter cal to convert them to usable units (pounds in your case), calculates the applied rate and creates an applied map.
I have an InCommand on the bench at the moment and could take some pictures if that would be helpful.
