PROGRAM MODE DEFINITIONS AND EXPLANATIONS
PROGRAM MODES
: Modes P1-P6 are PROGRAM modes that permit entering, changing, or re-
viewing programmed system parameters. PROGRAM modes P20 through P29 are reserved for
10 preset headings.
TO CYCLE THROUGH THE VARIOUS PROGRAMMABLE MODES,
depress and hold the
UPPER
mode button in for 3-5 seconds. The display will change automatically to mode P20. P20
is the first of your 10 PRESET headings. More on these later. Bump the
LOWER
mode button
down through modes P6, P5, P4, P3, P2, P1, AND
P0 CAL
. Go back up by bumping the
UPPER
mode button. The display will show current mode setting. The FACTORY DEFAULTS are listed
below. Most of the time these will never be changed. To program or change any setting, depress
the "CW" / UP or "CCW" / DOWN buttons until the desired setting is displayed. Change anything
or everything in the program mode except P6 and SAVE just once. NOTE: THIS IS DIFFERENT
FROM OLDER VERSIONS OF RC-2800’s. ( NOTE: DURING PROGRAMMING, THE NUMBERS
CHANGE SLOWLY AT FIRST THEN SPEED UP. RELEASING THE BUTTON AND PRESSING
IT AGAIN RESETS THE PROCESS OF SLOW TO FAST NUMBER CHANGE )
TO ENTER “PROGRAM MODE“: Press and hold the upper Mode button until P20 appears.
P20 through P29 contain preset headings. We put in our favorites but you can choose
your 10 favorite directions or presets and change the default settings anytime. One or all
can be changed and then saved as described below.
Bump the lower mode button once and
Mode P6
appears. For use with the OR2800
P6 is used
only to correct your heading if the antenna system was not clamped perfectly at the time
of installation or if your mast or antenna slips slightly in a high wind..
To change to a new
heading. touch the CW button. 0.0 should appear. Touch CW again. If the digits count up
( .1, .2 .3 etc.) continue until you near the corrected heading. Let off and press again. IF THE
NUMBER WON’T GO UP, WHEN CW IS PRESSED, then press the CCW button and proceed
until you approach the corrected heading. Let up and press again. If you overshoot, press the
other button until you get to the corrected heading. SAVE by pressing and holding the LOWER
MODE BUTTON until MODE 0 appears along with the current speed setting and your new, cor-
rected heading; example ( 0 8 23.5).
PROGRAM MODES, P5, P4, P3, P2, AND P1. THE DEFAULTS ARE SHOWN.
TO SAVE ANY OR ALL NEW PROGRAMMED SETTINGS AT THE SAME TIME EXCEPT FOR
P6:
Depress the
lower
mode button UNTIL MODE 0 APPEARS. P6 must be saved as soon as it
is set.
P5
=
1
This is the minimum SPEED and RAMP setting. A ‘1’ gives you full speed and ramp con-
trol. (NOTE: When trouble shooting a faulty operation, to get good motor voltage and reed switch
readings, it is helpful to temporarily set the speed to 9. This eliminates motor pulses and give a
steady DC reading for your DVM.)
P4
=
3960
This is the number of pulses from an OR-2800DC or AC for 360 degrees of rotation.
This number can also relate to the gear ratio of your rotator. Two pulses are formed for each mo-
tor rotation so your OR-2800 gear ratio is 1930:1. If you use an OR-2800 to turn your tower, and
you use a 2:1 step down for more torque, your mode P4 number would have to be changed to 2 x
3960 or 7290. ( the internal limit switches in the OR-2800 would have to be de-activated by re-
moving the limit arm inside the rotator). The RC-2800PX can handle pulse counts or gear ratios
of up to 40,000! The more pulse counts, the more accurate the rotation control and read-
