1.0 Operation
The Loup II Drill Monitor is a full featured monitor designed to provide accurate population
and seed flow information for conventional and air drills. This manual will familiarize you
with operation, calibration and technical information. All aspects and features are detailed
but may not be applicable to your system configuration.
The LOUP ELECTRONICS Drill Monitor is capable of monitoring and displaying:
Ground speed (Implemented Mounted Speed Sensor or optional Radar)
Population in Seeds/Acre (up to 24 sensors can be connected)
Spacing between seeds or Seeds per Foot (S/FT or IN/S)
Three shaft speed RPM’s (Left, Center & Right)
Seed Flow (up to 112 sensors can be connected)
Field Area
Total area
Three Hoppers (displayed as bargraph display)
Weight (Measured Weight in Hoppers)
Calc Pop (Calculated Population )
Area Left (Calculated Value of Area to be covered with remaining seed)
Weight/Area (Calculated Value of Area covered and seed used)
1.1 Normal Start-up
For everyday operation the Loup II monitor will remember all settings that have been saved
from the previous use. Press the power button in the lower right hand corner as shown in the

The first sensor the monitor will look for is a Speed sensor. This is an implement-mounted
sensor monitoring a shaft. Plug it in now. If no speed sensor is mounted on the drill, press
SELECT to Skip this Sensor.
Once the speed sensor has been accepted or skipped, the monitor will move to the next
sensor. The order the monitor will ask for sensors is shown below.
Speed
Shaft 1
Bin 1
Shaft 2
Bin 2
Shaft 3
Bin 3
Seed 1 through 24 (population sensors)
Blockage Module 1 through 8
Note: If during the Learn Mode you receive a
Wrong Sensor Type for: message, the
monitor is “seeing” a type of sensor other
than what is required for this function. For
example: This message would appear if
monitor asks for Shaft 1 but a hopper
sensor is plugged in.
4. A warning message now appears
asking Are you Sure? Press
SELECT to proceed or press
CANCEL to exit.
5. Install New System – Plug your
sensors in as the monitor asks for
them. For sensors that are

2.2 Implement Setup
2.2.1 Units
The Units setting changes the units of measure
that the monitor displays
Imperial = Acres/Feet/Miles per Hour
Metric = Hectares/Meters/ Kilometers per Hour
2.2.2 Implement Width
Adjust accordingly to the size of your drill
(i.e. 15ft, 20ft, 30ft, 40ft)
2.2.3 Clear Field Area
Use to zero or clear your Field Acres
2.2.4 Clear Total Area
Use to zero or clear your Total Acres

Loup Electronics 2960 North 38th Street Lincoln NE, 68504 [phone] 17
2.3 Speed Settings
2.3.1 Pulses Per Rev
Pulses per Rev (revolution) are the number of
magnets the implement mounted speed sensor
sees in one revolution of the shaft being
monitored. For most applications this number
will remain 4.
2.3.2 Wheel Pulses Per 400Ft
This is the ground speed calibration number for a
implement mounted speed sensor. Refer to
section 2.3.5 for calibration instructions.
The default number is 175
2.3.3 Radar Pulses Per 400 Ft
This is the ground speed calibration number for a radar speed sensor. Refer to section 2.3.5
for calibration instructions. The default number is 15151
2.3.4 Lift Switch
Lift Switch is used to tell the monitor if a lift sensor is being used to determine when you are
seeding and when you are not. The Lift Sensor is used when shaft rotation cannot be used or
a variable rate drive, common on air seeders, is being used.
If a Lift switch is to be used, a clutch activated shaft sensor must be learned as Shaft 1 and
this setting must be set to ENABLED.
2.3.5 Speed Calibration
All new systems require a ground speed calibration to ensure accurate population readings,
accurate area totals and accurate ground speed readings. To complete the calibration,
measure a course 400 feet long preferably on level ground with a start and finish point. The
drill must be in the down position throughout this procedure.
Note: During the calibration the monitor is looking for the number of pulses produced from
the drill mounted sensor or in the case of radar, the number of radar pulses. The monitor will
not display 400 when the speed calibration is complete rather it will display the pulses
counted in 400 feet.
