Research Concepts RC2000C - Manual (Page 3)

REVISION HISTORY
5.31.95 v 1.00
* Original code - derived from the RC2000A version 1.32 software. The tracking algorithms of
the RC2000B Az/El version 1.04 software were incorporated into the software. A different
memory map has been implemented. The RC2KF PLD (programmable logic device) should be
used.
Here are the major features of the RC2000C software...
*
dual axis inclined orbit satellite antenna controller
* RS-422 serial port supported
* will accept the RC2KPOL option for 24 volt DC polarization control with potentiometer feedback.
The tracking system has been enhanced with the following features...
*
an azimuth scale factor may be specified by the user so it is not necessary to program
geostationary satellites into memory before initiating a track on an inclined orbit satellite.
* the user may disable the Intelli-search function. When Intelli-search is disabled and search
mode is activated, the user is prompted to use the jog keys to manually align the antenna with
the satellite and then hit a key to initiate a step track operation.
* tracking for L-band (1.6 GHz.) weather satellites is supported.
The following features and capabilities were deleted from the RC2000A version 1.32 software to make
room for new features...
*
POL LIMITS mode has been deleted. The rotating feed limits are now specified via CONFIG
mode.
* angle display of polarization position for the RC2KPOL option is not supported.
* the satellite name display system has reduced capability. The controller will only display the
name of the satellite that was the target of the last auto-move operation.
11-22-95 v 1.10 Az/El, v 1.11 Polar, v 1.12 El/Az
This release of the software can be compiled to produce the following software versions...
* RC2000C Az/El version 1.10 for use with elevation over azimuth type antenna mounts.
* RC2000C Polar version 1.11 for use with polar mounts with a power declination adjustment.
* RC2000C El/Az version 1.12 for use with azimuth over elevation type antenna mounts.
The manual for the RC2000C Az/El was derived from the RC2000C Az/El version 1.00 manual. The
manual for the RC2000C Polar was derived from the RC2000C Polar version 1.02 manual. The manual
for the RC2000C El/Az is the same as is used for the RC2000C Az/El, with an addendum that describes
the few differences between the Az/El and El/Az versions.
The following modifications to the software have occurred:
The track table update flags have been implemented in a different manner. In previous
versions of the software the update flags were implemented in a manner which limited the
range of elevation position values which could be stored in the table to values in the range of 30
to 32767.
The reply to the REMOTE mode Query ID command has been changed to report the various
mount types supported by these versions of the software.
The Remote Communications Protocol documentation has been modified to describe the track
related alarm codes.
New satellite lists have been created.
Two new PC programs, ANTENNA2.EXE and SCALE4.EXE, have been created to support the
azimuth over elevation mount type.
The default value of the Search Width CONFIG mode item has been changed from 5 to 3.
