Hi Ive noticed a few members using this controller, i bought mine a few years ago now and just getting round to using it and the battery is low so ive been and bought a replacement,
If anyone has the same issue this is the battery needed.
LOW BATTERY
The RC2000C constantly monitors the level of
the lithium battery. When the battery voltage
level is low, this error code will appear. Replac
e the battery with a Duracell DL2450. Make
sure that the unit is unplugged from the AC
power before removing the cover to change the
battery. Take care to hold the battery holder
tab (positive terminal)
away from the negative
terminal of the battery holder housing while repl
acing the battery and it will not be necessary to
reprogram the memory. Since there is a chanc
e that the non-volatile memory will be corrupted
when the battery is changed, please refer to t
he Appendix entitled 'Restoring the Non-Volatile
Memory' before changing the battery.
RC2000C Az/El Tracking Antenna Controller
Restoring Non-Volatile Memory
This appendix outlines a procedure that
allows the user to restore the
contents of non-volatile memory.
A number of events can make this necessary, including:
i. changing the battery which powers the non-volat
ile memory and allowing the center tab of the
battery holder to touch the base of the battery holder,
ii. performing maintenance on the controller,
iii. swapping one controller out for another, or
iv. upgrading to a newer version of the software which
uses a memory map different from the original
memory map.
Here is the procedure ...
1. In manual mode, jog the antenna to the Azim CW
and Elev up limit. Record the position count
value for each axis just before the limit is reached.
(If position display in degrees is enabled, disable
that feature before starting this procedure.)
2. Go to CONFIG mode and record the value of each CONFIG mode item.
3. Using AUTO mode, position the antenna on eac
h of the geostationary satellites stored in non-
volatile memory. Record the azimuth and elev
ation positions and the longitude value of each
geostationary satellite. Use the H and V keys to pos
ition the polarization control device (if one is
present in the system). Record the H and V positi
ons for each satellite. (If polarization position
display in degrees is enabled, disable that feature.)
4. Move the antenna to the position just before
the Azim CCW and down limits are reached. This
should correspond to a position count value of
30 for both the azimuth and elevation axis.
5. Turn the unit off, unplug the unit from the
AC power, and perform whatever maintenance is
required. If the EPROM is replaced, be sure to in
sert the chip into the socket properly. The notch
on the end of the chip should line up with the not
ch of the outline silk-screened onto the printed
circuit board under the EPROM socket. When t
he maintenance has been performed, power the
unit up. If the non-volatile memory has been corrupted,
the unit will either go to LIMITS mode or will
flash an error message on the bottom line of the displa
y. If this occurs, the following steps of this
procedure will have to be performed to restore the non-volatile memory.
6. Go to LIMITS mode. WITHOUT MOVING THE
ANTENNA set the Elev down and Azim CCW limits.
AFTER THE AZIM CCW AND DOWN LIMITS H
AVE BEEN SET, jog the antenna to the positions
for the Azim CW and up limit recorded in step 1.
Set the AZIM CW and up limits. After the AZIM
CW and up limits have been set, exit LIMI
TS mode by hitting the MODE KEY.
7. Go to CONFIG mode and key in the data recorded
in step 2 above. Each entry must be terminated
with the ENTER key. After the data has
been entered scroll through the CONFIG mode items
(using the SCROLL keys) and make sure
that the data has been entered correctly.
8. In this step, the positions of the geostationary sa
tellites are stored in non-volatile memory. Go to
SETUP mode. Position the antenna on each of the sa
tellites that were recorded in step 3 above.
The satellites should be found at the locations that
were recorded in step 3 above. Select the
satellite name, enter the satellite longitude, and move
the polarization control device to the H and V
positions in response to the appropriate SETUP mode prompts.
