DIMM Logging
- The DIMM log is in
/lbt/data/logs/dimmon thedimmhost (rsync'ed to Tucson). The application runs asdimmuser.
- Exceptions caught in the DIMM software sometimes recover automatically - like mount exceptions when using auto-acquisition - sometimes going to the next star in the list clears the problem with the mount.
- If there is a connection problem to the mount or camera, often a power-cycle of the DIMM electronics fixes it. See Operators/DIMMTroubleShooting for the link to the PDU.
Note that it takes the mount a couple minutes to be ready after a power-cycle. DO NOT kill the software before the mount completes its homing or it can go into a hard-limit condition.
| Error: DimmMountBisque::init CommException caught - CommSerial - Connection timeout DimmMountBisque::xxxxx CommException caught - CommSerial - Broken pipe DimmMountBisque::xxxxx CommException caught - CommSerial - Connection refused |
cannot connect to mount | this can be a fiber connection problem or a problem with the IP of the mount (hardcoded in mksdriver.cpp) or a power problem - sometimes power-cycling the DIMM electronics works |
| CameraException exception caught - No connection to camera. | cannot connect to DIMM camera | if it happens on multiple connection attempts, sometimes a power-cycle of the DIMM electronics fixes it |
| Error: connectCamera, CameraException caught - Couldn't open channel to EDT card. | cannot connect to DIMM camera - cannot see /dev/edt |
check that the edt module is installed in the Linux kernel, check the /etc/init.d/edtinit runs ok |
| Error: Stars out of region-of-interest...stop measuring | seeingBufferFilled and value=-1 | Centroiding failed - seeing value reverted to -1. stops measuring; resets ROI to full-frame |
| Error: AutoAcquire: didn't find a web cam centroid after configured tries, exiting | auto-acquisition failed to find a centroid in the Dimm.Acquisition.starsToTry configured limit and exited |
have to restart Acquisition from the GUI |
| Error: MountBisque - goToRADEC: Position out of bounds! | exception thrown when RA/DEC requested is out of the range of the configured values; current config values (as of June-2012) are -8 to 30 in azimuth, -30 to 85 in elevation | doesn't move to the position or set tracking true |
| Error: calculateTrackingRates - axis rates -nnn nnn out of bounds | future-current/(10sec*3600) is > 3600 | sets the rate to 0 |
| Warning: LBT is not tracking. | comes from DimmMountBisque::update() ; reading dd entry IIFOnSource |
If motion is too much, sets tracking to FALSE; otherwise still calculates rates and continues |
| Warning: Stars close to the edge minX:48.92 maxX:115.18 minY:138.90 maxY:144.75 | Within configured Dimm.limitGuide value of the 200x200 measuring frame |
after the configured Dimm.minFramesToGuide are seen, it sends a guide correction |
| Warning: LBT motion is out of range, stop tracking mount. | only seen in conjunction with previous message, when difference in current and pointing AZ or EL values are > LBT offset limit | turns off tracking |
| Warning: DimmImageHandler::calculateSeeing dist_x=XX dist_y=YY - out of bounds | centroids in image buffer that are too far apart | centroids are thrown out |
| Warning: DimmImageHandler::calculateSeeing no seeing calculation, problem count: 272 listDxy size: 28 | problem centroids are too many, not performing a seeing measurement | |
| MountBisque: slewHome: move to Factory home position MKSDriver: startFindHome: ENTER MKSDriver::isFindHomeComplete: Exit ... MountBisque: slewHome: ... found Factory home position |
On a power-cycle, the mount will go to the factory home limits in each direction - it takes a couple minutes, so (IF IN TRACE MODE) you'll see loads of log messages while it's trying to find home and then slew to the DIMM home position. |
