A. SYSTEM OVERVIEW
The DICKEY-john Seed Manager®
Population Monitor uses the latest
microprocessor-based technology to
take the guesswork out of the planting
operation. Any time seeds are not going
to the ground at the correct rate or
another error condition occurs, an
alarm is sounded and a message and
row number, if appropriate, are dis-
played.
Seed Manager®offers features such as
improved seed counting accuracy, simpli-
fied harnessing, advanced error diagnos-
tics, and seed singulation when used with
the new Seed Smart®sensors. It is also
compatible with the DICKEY-john
Standard and Hi-Rate seed sensors.
Additional features include a bargraph
presentation of row-to-row planter
performance, high and low population
warnings, faster population updates, and
the ability to disable individual row
sensors from the monitor. An RS-232
interface is available for precision farming
applications.
The Seed Manager®Population Monitor can
monitor up to 36 rows. It stores planter
configuration data and accumulated opera-
tional data in nonvolatile memory, retaining
information even when disconnected from
the tractor battery.
Figure 1 shows the Seed Manager®Popula-
tion Monitor console. It consists of two
custom Liquid Crystal Displays (LCDs) and
twelve membrane switches. The top LCD
display shows messages for the selected

Operate Mode function, Setup Mode
constant, or Alarm Mode identifier and the
value on a 5-digit numeric display. A 2-Digit
numeric display identifies the row. The
bottom LCD displays graphically the relative
populations of 12 rows simultaneously.
Larger planters have row groups dis-
played on a time-shared basis.
B. SWITCH OVERVIEW
The switches are used to control system
power, select the mode of operation, and
enter planter configuration constants. To
help distinguish between switch names
and display messages in the text of this
manual, switch names are always shown
in italicized print. An overview of the
switches follows:
1. ON•OFF
Pressing this switch applies power to the
monitor. Upon power up, the monitor
performs internal diagnostic checks,
illuminates all segments of the LCDs,
sounds the alarm, and determines what
type of seed sensor harness is connected.
Depressing the ON•OFF switch for at
least one second causes the monitor to
power down.
2. ALARM
Momentarily pressing this switch silences
the alarm and acknowledges the alarm
condition. Additionally, holding the
switch pressed for more than one second
allows the volume level of the alarm to be
adjusted. As the switch is held pressed,
the alarm sounds continuously and the
volume level slowly decreases to a minimum,
then increases to a maximum. Releasing the
switch establishes the desired volume level.
3. SETUP
This switch is pressed for one (1) second
to enter the Setup Mode and to step from
one Setup constant to the next as detailed
in the SETUP chapter.
4. MIN-AVG-MAX•SCAN
This switch is pressed to toggle between
the MIN-AVG-MAX and SCAN options
for the function selected by the Popula-
tion• Spacing•Singulation switch.
5. SELECT ROW
Pressing this switch while in the Popula-
tion, Spacing, or Singulation functions
freezes the upper LCD display on the
current row data. Successive depressions
then cause stepping from one row to the
next. In the Setup Mode, this switch
allows stepping through the rows while
entering Row Status.
6. SELECT, SET, and CLEAR
These switches are used to change constants
in the Setup Mode as explained in the
SETUP chapter. The CLEAR switch is also
used in the Operate Mode to reset the area
and distance accumulators and the Run
Hours function. The SELECT switch is used
in the Operate Mode to select various
Bargraph Display/Sections.
7. START•STOP
This switch is used in the Operate Mode
Seed Count, Distance Accumulator, and
Bargraph Lock & Hold functions. In the
Setup Mode, it is used for the Distance
Calibration and the Sensor Self-Test.

7. Population Filter Value
In certain applications the Seed Manager®,
due to its rapid update rate, might exhibit
fluctuations in population, spacing, and
singulation that are undesirable to the
operator. The population filtering option
applies an averaging filter to the population,
and seed spacing calculations. The filter
values range from 0 to 99, with 0 having no
filtering effect and 99 being the maximum
filtering value. Use the SET and SELECT
switches to adjust the filtering value. Figure 8
shows a light filter value of 15.

B. SETUP CONSTANTS
The Setup Mode is used to enter the planter
configuration constants which are listed in
Figure 12, in the order of their presentation.
Depressing the Setup switch for one (1)
second places the console in the Setup
Mode, which is identified by the SETUP
message on the display. Additional messages
uniquely identify the constant displayed and
available for editing at any given time.
Each constant has a fixed number of digits.
Leading zeroes are displayed. When it is
desired to change the value of a constant, use
the SELECT, SET, and CLEAR switches as
follows:
Initially, the left most digit flashes on and
off, indicating it is the “selected digit”.
Each depression of the SET switch
increases the selected digit by one count.
After reaching the maximum value of
nine (9), the digit rolls over to zero (0).
Pressing CLEAR zeroes the digit. Each
depression of the SELECT switch makes
the next digit to the right the selected
digit.
When the desired value is entered (or
there is no change from the original
value), press the Setup switch to store
the value and advance to the next
constant on the list. If a value is
entered which exceeds the minimum
or maximum shown for that constant

2. ROW Status
This parameter allows placing individual seed
sensors in ON, OFF, or SKIP status. For
those situations where it is necessary to turn
off certain rows on the planter (for example,
with skip row planters or when planting point
rows or seed corn), OFF status turns off the
related sensors so alarms do not occur. The
SKIP status setting, available only with Seed
Smart®sensors, allows removing a failed
sensor from the harness “daisy-chain” (and
jumpering with an extension harness) without
disrupting row numbering.

This is the planting width of the planter in
inches (centimeters) with a resolution of
0.1. It is automatically calculated when
either the NUMber of ROWS or the
ROW WIDTH is changed and can be
edited for special applications such as skip
row planters. Figure 18 shows an IMPlement
WIDTH of 720 inches.
8. Shaft Speed Constant
The Shaft Speed Constant is the number of
pulses the shaft speed sensor generates in
one revolution of the monitored shaft. This is
typically the number of teeth (sense points)
on the gear attached to the monitored shaft.
If the sense gear is not directly attached to
the monitored shaft, the Shaft Speed
Constant can be entered as a decimal with
0.01 resolution. Entering a value of zero
(000.00) disables the Shaft Speed function.
Figure 19 shows the display with the SETUP
and RPM messages and a Shaft Speed
Constant of 26 pulses per revolution.

enabled in the customer setup mode. Setting
the Lo Pressure Warning Limit will cause the
audible alarm to sound when the pressure

falls below the value that has been entered.
Utilize the SELECT and SET switch to enter
the Lo Pressure Warning Limit. The Lo
Pressure Warning Limit can be enabled or
disabled by selecting the ON or OFF symbol
after the rightmost digit. Pressing the SET
switch will toggle the status of the warning
from ON to OFF. Figure 23 shows a Lo
Pressure Warning Limit of 5 oz/in2 with the
alarm turned OFF.
13. Distance Calibration
The Distance Calibration Constant is the
number of pulses generated by the
ground speed sensor while traveling a
distance of 400 feet (122 meters). Figure 24
shows the display with the SETUP, SPEED,
and COUNT messages and the default value
of 6096, which is the nominal pulse count for
the radar ground speed sensor. A smaller
number, typically 3100, results with a
reluctance ground speed sensor.
To perform the Distance Calibration:
Step 1.
Carefully measure a 400 foot (122 meter)
course, plainly marking the start and finish
points.
Step 2.
With the tractor moving between 2 and 5
MPH (3.2 and 8Km/h), press the
START•STOP switch when the tractor
is exactly even with the start marker. The
display showing the Distance Calibration
Constant zeroes, then counts the ground
speed pulses.
Step 3.
When even with the finish marker,
press the START•STOP switch.
Step 4.
To ensure best accuracy, perform this
procedure at least three times. Record the
count each time, then enter the average as
the Distance Calibration Constant, using
the SELECT and SET switches.

14. Sensor Self-Test
This test functions differently depending
upon the type of seed sensors used on the
planter. It is identified on the display by
the SETUP, TEST, and ROW messages.
Start the test by pressing the START•
STOP switch. The TEST message flashes
while the test is executing and PASSED
appears when complete. (This same test is
performed automatically during console
power up.)
If one or more sensors fail, the message
FAILED and the row number of the first
failed sensor is displayed. When multiple
sensors fail, the "S" appears after the
ROW message (displaying the message
ROWS) and the SELECT ROW switch can
be pressed to step through the failed row
numbers. Figure 25 shows the display when
multiple rows have failed.
If Standard or Hi-Rate sensors are used, each
sensor is tested in sequence. The number of
sensors passing is then compared with the
NUMber of ROWS and IMPlement Type
Configuration parameters to ensure agree-
ment.
For Seed Smart® sensors, the light path,
circuitry, and communication link of each
sensor is tested by an instruction which
simulates dropping seeds, resulting in
more comprehensive diagnostic informa-
tion. Figure 26 shows the error codes
possible (See ALARMS & ERROR CODES
