2.26.96 v 1.20 Az/El, v 1.21 Polar, v 1.22 El/Az
The polar version of this software was modified to work with a polar mount that employs either a
motorized declination or motorized latitude angle adjustment. A new CONFIG mode prompt named
Mount Type has been added to allow the user to specify either motorized latitude or motorized
declination.
For all versions of the software the maximum number of inclined orbit satellites has been increased to 5
and the maximum total number of satellites has been increased to 38.
The reply to the remote Query ID command has been changed to reflect the new version numbers.
1.3.97 v 1.30 Az/El, v 1.31 Polar, v 1.32 El/Az, v 1.33 DDT, v 1.34 Az/El (Prodelin 3.8 m.)
Support was added for the watchdog timer. JMP 1 near the battery should be installed to implement the
watchdog.
If the controller is tracking an inclined orbit satellite in the STEP sub-mode when a power-down occurs,
on power-up the controller checks to see if signal strength is present. If so, the controller resumes
tracking in the STEP sub-mode without user intervention.
The sense of azimuth movement has been redefined. Rather than east and west counter-clockwise
and clockwise are defined as seen by an observer located above the antenna.
The runaway sense system can be configured to accept a number of stray pulses before declaring a
runaway.
A special version of the software has been defined for the DDT (v1.33). Here are the modifications:
Polarization control features of the controller have been made invisible.
A global track table Az/El position clear has been implemented via RESET mode.
The L Band stuff has been replaced with X Band.
Unique 'system reset' CONFIG Mode item values are supported.
A special version of the software has been created for the Prodelin 3.8 meter antenna (v1.34). Unique
'system reset' CONFIG mode item values are supported and the runaway sense system requires 4
counts to trigger a runaway.
The reply to the Remote Query ID command has been changed to reflect the new version numbers.
2.9.98 v1.4x
Updated the satellite list.
Fixed Resync mode LCD display bug.
Corrected bug that could caused reset due to the watchdog timer when initiating track on inclined orbit
satellite with Azim constant set at 0.
9.24.02 v1.4x
Changed specification for 115 VAC and 230 VAC fuse replacement.
03.23.11
Added RC1KADP Schematic
