RC3000 Antenna Controller | Chapter 3 | Detailed Operation |
3.2.2.2 Stow
The STOW mode automatically moves to the mount’s predefined “stow” position. See appendix B for the list of stow positions for the various mounts supported.
Like the DEPLOY mode, STOW requires an explicit confirmation to initiate movement.
<MODE>MENU (DO NOT STOW) | STOW |
<BKSP>CONTINUE STOW
After initiation a sequence of movements will be performed to stow the antenna. The sequence of axes movements will be mount dependent. As each axis moves, its label (AZIM/ELEV/POL) will flash and the current position will update. The target stow positions will be displayed in parenthesis.

The following describes a typical sequence of movements:
-the azimuth axis is moved to its stow position (typically AZIM:0.0). After moving to this indicated position, the RC3000 will confirm the position by looking to see if the azimuth stow switch is active. If the azimuth stow switch is not recognized, the mount will be moved a short distance either side of the current position trying to find the azimuth stow switch. If the controller fails to see the azimuth stow switch the following message will be displayed: “*CANNOT FIND AZ STOW SWITCH* <MODE>EXIT” and no further stow movements will be performed.
-if stowing of the polarization axis is enabled, the polarization axis will next move to its defined stow position. As with the azimuth axis, if a polarization stow switch (if the mount is so equipped) is not confirmed then the message “*CANNOT FIND POL STOW SWITCH* <MODE>EXIT” will be displayed and no further stow movements will be performed.
-if the azimuth and optional polarization movements complete successfully then the elevation axis will move to its stow position. Typically this movement ends when the elevation stow limit is encountered.
Following completion of movement to the stow position, the RC3000 will return to MANUAL mode. The automatic movement may be terminated anytime by pressing the Stop key.
Many mounts have unique stow sequence requirements. Check appendix B to see if your mount has any unique stow situations. Stow and deploy parameters may be customized via the Stow and Deploy Positions configuration screen (3.3.1.3.10). Typically the default parameters will be correct for a particular mount.
