Research Concepts RC2000A - Manual (Page 9)

9.19.00 v 2.30/ v2.31 Effective S/N 3342
The satellite list has been upgraded.
The user can modify the operation of the runaway alarm sensing system via the values assigned to the
Azim Fast Deadband and Elev Fast Deadband CONFIG mode items. Each axis can be configured
separately.
01.27.05 v 2.6x
We have added Addendum I to the manual. This addendum addresses the following features;
* Support added for a signal strength based peakup after automatic moves.
* Communication protocol enhanced to support ...
• Upload/download of CONFIG mode and satellite data.
• Remote front panel emulation via a keystuff command and display reflect command. This
allows remote access to all receiver functions.
• The RC2000A can service a remote Device Status Poll command without switching to
REMOTE mode.
* The Rotating Feed Present CONFIG mode item has been replaced with the Pol Control? CONFIG
mode item. The Pol Control? CONFIG item allows the user to specify i) no polarization control
device, ii) one port polarization control, iii) two port polarization control, or iv) Chapparal Polarotor
type three wire servo.
* Signal strength can be input to the controller via the AGC1 and AGC2 analog inputs. Signal Strength
is displayed in MANUAL, SETUP, LIMITS, and REMOTE modes. In MANUAL mode, the scroll up
and Scroll Down allow the user to select either AGC1 or AGC2 for display.
* The controller supports a Sticky Key Jog. With Sticky Key Jog, in MANUAL mode an az/el jog is
initiated by hitting the Az CCW, Az CW, El Down, or El Up keys. Once a sticky key jog is initiated it
will continue until the user his the Stop key or leaves MANUAL mode.
* The warning messages that the user encounters on entry to POL LIMITS mode has been modified
so that ‘POL LIMITS’ is always displayed in the upper right hand corner of the LCD.
* A bug that sometimes resulted in erratic display of satellite information in AUTO and SETUP modes
when scrolling through a list of satellites with the Scroll Up/Down keys has been fixed. This problem
is more prevalent on RC2000C Tracking Controllers.
* The controller’s VONFIG mode has been modified to allow access to a CONFIG mode item anytime
the item does not contain valid data and Expert Access Mode is enabled.
* Bug Fix
* The reply to the Query ID remote command was modified to include the correct command code.
