Normally if you have the right boxes checked the HC is enabled to be downloaded but cannot be updated until you reboot the Gemini 2 by powering off then powering back up.? You get a updating HC firmware message which can take a long time but eventually it will update and reboot.? Sometimes the Gemini 2 need to be power cycled to get it to wake up after this which AFAIK is normal.?

?

If you have connected to the Gemini-2 over your LAN and can access the Gemini-2 using the network you can also just copy the HC file to the right directory in the Gemini-2 and when the Gemini 2 is power cycled it will update the firmware as above.? ??

The servo imposed limit is written so you should always be able to back out of the limit.

I was having issues with Nina slewing to the target after plate solving. Giving declination not reachable even though I was less than a half degree from the target. Tried updating drivers, ?ascom drivers, etc. I was just about to give up when I decided in the framing wizard to hit obtain coordinates from mount. And everything started working. Unfortunately I got a new refractor, which brought clouds as soon as I figured out the solution!

Losmandy has replacement screens ? ? ?Also repairers?

I think your best bet is Losmandy directly or one of the repairers in these forums. If you are in the US Michael Herman is your guy, in the UK or Europe, David Partridge is your bloke, in Australia Brendan is your… hmm, what’s the slang for man in oz? :)

Interesting that UV will damage the screen to that extent. I watch and image the sun from time to time so I’ll make a conscious effort to shade it from the sun. Thanks for the heads up

Hi,

?

I have two Gemini-2 units.? One for my CG-11 (OPW+SLW upgraded) and G-11 (OPW only).

For CG-11's Gemini-2, I've noticed that the response time when I select "Configure PEC" on virtual HC is very slow, "Configure PEC" window appears after more than 10 seconds have passed.? Also after I select "Set PEC Period", again its confirmation window appears after 15 seconds or so, following "Not Responding" message in the title bar.

I've carried out the same test for G-11's Gemini-2.? When I press "Configure PEC", almost immediately "Configure PEC" window appears.? There is no time lag.

I used the same ASCOM Gemini Telescope driver 1.1.28.0.? But the FW versions are different.

?

For CG-11: Gemini unit ver. 6.10,? HC ver. 1.63

For G-11: Gemini unit ver. 6.01, HC ver. 1.60

?

I put Gemini Troubleshooting Reporter logs in Yamada-2 folder in User_Logs_error_files_and_suggestions.

?

Thanks in advance,

If you update the older firmware to the current L6.1 and HC v1.63 some of the differences might go away.??

I hope this is not too dumb a suggestion so bear with me. If the mount was guiding when it hit the safety limit then the speed was likely set to guide rate. Trying to move the scope away from the limit at that speed is kinda tedious, it will look like nothing is happening. Just make sure you change the speed manually to something faster, like slew or move.?

I haven’t had this issue but, then again, I’m still at level 5 so maybe there is a difference with level 6?

?

good luck

Strange, as I seem to be able to use both, the tactile buttons in the back and the touch-screen buttons in the front to move out of the safety limit. Going past the safety limit works at centering speed, to avoid accidental collision with the mount. I just tested this three times with mount restarts in between... I wonder if there's some other setting that affects this behavior that I don't have?

I don’t know about the original poster, but i can attest to my experience. Every time i hit a safety limit i am unable to move it without going cwd first. which makes setting new limits difficult if not impossible without manually changing to a much bigger range then setting a new limit by slewing.

I have not tried using the virtual HC buttons for this, but i have used them for other things, and there is usually a lag between me hitting stop or letting go and the mount following. Does not matter if it’s usb or ethernet same behavior. so i dont use that for safety limits.

Ken, be careful when using automation software -- it's entirely possible that a command was sent to Gemini put in a park state while waiting for the meridian crossing to do a flip. Gemini has multiple park states, and some of these prevent the mount from moving with HC until the mount is unparked.

Hi Paul - thanks and my situations were just during normal imaging sessions with a target that tracked into the mount limits. The HC and virtual HC buttons didn't work similar to what I think David is saying. At that stage I just use the HC to go park at CWD and then use the HC to go to the target again - no automation software is involved (same as Ryan does).

Hope that clarifies a little more.

Is there a source for replacement touch screens for the G2 HC??

?

3 year old GM811G screen has been damaged by sun UV exposure over time, such that it is difficult to read.?

Thanks!

I'm sure I've found the solution to solve this issue, though I don't know exactly the mechanism of the problem.

My Gemini-2 for CG-11 (SLW&OPW) was directly connected to my NUC #2 without router.? I assigned the different network to this connection.? Then NUC #2 mounted on OTA was connected to my home network through Wi-Fi.

I've changed to make the Gemini-2 unit join the home network by connecting to a Wi-Fi router.? The unit now becomes one of other devices on the home network.

Under this configuration, I see no response delay.? Still I don't understand why the direct connection between the unit and X270 / NUC #1 doesn't show this issue.

For the time being, I will keep this configuration for my CG-11's Gemini-2.

Best regards,

I have had that (albeit rarely) and usually when it was approaching a meridian flip - odd because it handles flips 99.9% of the time. I usually tell it to park at CWD and then goto the target again - which it did on the other mount side.

Sorry it is not an answer to why but maybe a workaround in a blocked situation.

What am I missing?
