- | This might mean that the gain for the tracking servo is wrong. Note that changing this gain can be dangerous, especially if you set it too high as that can cause the telescope to oscillated and damage the drives. Please only do this if you are very very sure that it is necessary. Symptoms of bad gain are: The scope over shoots the position while slewing. The star will be seen to move out of the window and may come back after a few seconds. This means the slewing gain is too low. The scope oscillates when tracking or after a slew. The star will be tracing an ellipse, figure eight or other looping shape. This means the tracking gain is too low. You can damp this out with the telescope or dome gui by disabling the scope, then re-enabling it. Adjust the gain upward and watch it on the next slew.

- | Before you start the tiptilt server, you must ensure that the power to the cooling system and the CCD iteslf is on. It is extremely important that the cooler be running before you turn on the CCD and is only turned off if you are sure the CCD is NOT running. You can start the server from the X windows menu or with the command xtiptilt. \\ \\ | ||
- | Note that there are background counts and read noise to deal with. Whenever you change the frame rate, please ensure that the bias frame is OK. The server will attempt to load an old bias frame that should work, but if things are not working, try making a new bias frame by ensuring that the detector is in the dark and typing " | ||

- | ==== Tiptilt server complains about the CCD ==== | ||
- | |||
- | Is the CCD turned on? When the tiptilt server starts up it tries no more than five times to communicate with the CCD. If they all fail, it will give up. If this happens, try cycling the power to the CCD and try again. If this fails, connect to the tiptilt machine and type the command rtccdAPIDemo, | ||
- | Note that it is never a good idea to reboot machines unless you are very very sure it is necessary. The only reason to reboot tiptilt, other than a lock up of some kind, is that the clock interrupt has failed. You can test this by running the command " | ||
- | Also note that cycling the power on the CCD can cause harm so be sure you need to do it before trying it. Also, it is important to wait for at least 20 seconds after turning off the power before turning it on again. | ||

- | |||
- | Sometimes the telescope server will not show that TT is running. It will show 0Hz for a signal rate for TT. Running TIPTILT COMM will not get it started while other scopes do show it starting. Close and restart any telescope servers that won't connect after two tries of TIPTILT COMM. \\ | ||
- | Note: There is more info in the software manual on this topic, but I wasn't sure if it was still relevant. | ||
- | |||
- | ==== Tiptilt server says the clock isn't running ==== | ||
- | |||
- | First check whether the clock itself is running and the other machines receive the clock signal. Look at the clock cards at the back of other computers in the rack. The clock cards have three LEDs, one yellow and two greens. If the computer is receiving the clock signal properly all three LEDs should blink, but at a different rate. If the LEDs on all the clock cards are solid then reboot the GPS computer. When the GPS computer is down, it is best to cycle the power also on the box right above the GPS computer. \\ \\ | ||
- | If the clock appears to be working properly on other machines and not on the tiptilt now it is time to reboot tiptilt. \\ \\ | ||
- | [There is a bug in the real time part of the CCD code. It is caused by the clock in the tiptilt system either not running at all or having been set to a time very different from the last time the CCD ran.] \\ \\ | ||
- | For the time being the only solution is to reboot tiptilt, but do so from the lab. Power OFF the CCD, then reboot the tiptilt machine and go into the BIOS. Make sure that interrupt 11 has been set to ISA legacy, save the BIOS and reboot. When the clock card LEDs in the tiptilt machine indicate proper clock signal, turn the CCD back on and start the tiptilt server. \\ \\ | ||
- | Also, sometimes Serial Port 3 grabs IRQ 11 which stops the clock from running. Since there is no serial port 2 it's safe to disable this in the BIOS. This problem normally comes up when there has been a power outage. \\ \\ | ||
- | Sometimes syncing the clock can also cause this problem, but that should be fixed soon. If it does, exit the tiptilt server, log in as root, and reload the tiptilt model using the following commands: \\ | ||
- | /sbin/rmmod tiptilt_rt \\ | ||
- | / | ||
- | Note that it is never a good idea to reboot machines unless you are very very sure it is necessary. The only reason to reboot tiptilt, other than a lock up of some kind, is that the clock interrupt has failed. You can test this by running the command " | ||

- | * Check the ACQ alignment to make sure the tick marks are centered on the laser. | ||
- | * If there is plenty of starlight getting into tiptilt, then try re-initializing by clicking [TIPTILT COMM] on Cosmic Debris. | ||
- | * If there are a large number of background counts on TT, then close the M5 cover on the telescope, and click [DBIAS] on the TIPLTILT GUI to clear the background counts. Re-open the M5 cover. | ||
- | * If a star drifts even with TT locked, there could be a bright sky or light from other beams getting into the affected telescope' | ||
- | * If TT unlocks and the star drifts, the TT servo may not have engaged. This is engaged with the TIPTILT button on the telescope gui. Clicking it may not start the servo the first time. Try it again if the green dots drift on the TT plot windows or if the Servo status in the telescope gui reads None instead of Wobb 1. | ||

Sometimes you can also see the oscillation in the white starlight dots or as an elongation of the star when looking at the ACQ field while tiptilt is locked.

* Good metrology signals are important to the proper positioning of the carts. Monitor the signal strength by running [RUN MULTIPLE] on the Metrology Monitor. Place the windows above the TV windows for each scope you are using. They should show white sine waves that are around the height of the window. Erratic, fluctuating waves indicate self-interference or a weak signal. This may cause the carts to lose their place as the signal strength falls too low.
