2.0 RC1000A REVISION HISTORY
DATE VERSION DESCRIPTION
12-20-89 1.0 - Original
4-23-90 1.1 - Allowed the user to specify the 'SLOW' mode speed index.
4-26-90 2.0 - Allowed the user to specify the 'FAST' mode speed index.
- Added new satellites to the preset select list.
8-24-90 2.1 - Implemented motion detect alarm software to protect the
antenna in the event of a sensor failure. When an error is
sensed, the RC1000A displays "ANT/SENSOR ERROR" and
halts drive signals after 2 seconds.
- Implemented a relative SKEW position display whenever the CW
or CCW SKEW keys are depressed and the position field is
active. Relative position is between P00 and P99.
- Autoscaled reed count input to work with any sensor resolution.
Count is scaled between the EAST and WEST limits with WEST
being mapped to a count of 980.
10-4-90 2.2 - The unit now automatically carries over the correct polarization
position upon termination of an AUTO move.
- Allowed the user to OVERWRITE position data when in SET
mode instead of allowing multiple positions with the same name.
- Alphabetized satellite preset list.
12-20-90 2.3 - Major revision to accommodate future remote PC software.
Added Auto-Pol feature whereby Pol control can be slaved to a
receiver. Changed display format to indicate relative position of
antenna to a target by making use of lower and upper case
names. Re-ordered satellite list by longitude. When
programming, controller returns to last used location in SET list
instead of starting from the beginning.
1-30-91 2.31 - The satellite list presented to the user in AUTO mode is now
sorted by ascending orbital position. SBS6 and Galaxy6 were
added to the SET mode list. A small positioning bug, found only
in V2.3, was fixed.
6-12-91 2.32 - updated satellite list.
- Accommodated hall effect sensor, changed fuse type.
1-3-92 2.33 - Updated satellite list.
4-10-92 2.34 - Updated satellite list.
4-14-93 2.40 - Updated satellite list.
Corrected bug in sat name display and H/V pol recall system.
3-17-94 2.41 - Updated satellite list.
4-15-98
- The RC1KS1 Comm option is now included as a standard
feature in all RC1000 units.
