Re: Losing Communications with the Mount

Howard Hedlund
 

Hi Alex,
For starters, I would hook up a USB cable as your backup COM port in APCC.  That's just a good idea regardless.  Ethernet connections through a network are usually our preferred method for communicating.  Here are a few things to consider:
  • Do each of these things one at a time, or you'll never know what the actual problem was.
  • Ray mentioned increasing the timeout to 300 mSec.  I would go even higher, especially if you have other users on this same network. If you have 2 or 3 people on the same home network, all streaming different 4K movies, you are bound to need occasional longer timeouts for the mount.  The IEEE protocol (if I understand and remember correctly) was originally set up for timeouts up to 3000 mSec (3 seconds).
  • Try a new cable or cables, and try a different port on your router or switch.  Check the cable ends, and check the receptacle.  Outdoor switches in observatories are great places for spiders to call home.
  • Change from the network (GTOCP4 is a client) to operating peer-to-peer (GTOCP4 is a server).  This setting can be changed on the webpage if you can access it.  It can also be changed using USB or serial and the SerialUtilities.jar program that is on your thumb drive.  You MUST power-cycle the CP4 for any changes to take effect.
  • If none of the above seems to help: 1. ground yourself to allow any static to discharge.  2. Carefully remove the white top cover of the CP4.  Mind the WiFi antenna lead!  The left side is taken up by a digital board that is mounted on the main board below.  3. Note whether there are screws or snap fittings holding the board in place.  The board may have been knocked partially loose by rough handling from shippers.  This is unlikely if the CP4 is new enough to have the screws, but either way, check that the board is properly seated.  The location of the connector between the boards is shown on the photo.  (This board is a prototype and will look a bit different from yours.)  This is the only place that may need reseating.
  • If you continue to have issues, call me at AP.


Re: 400 Mount Seen on eBay

I think this is the same one I saw in a Craigslist posting recently.  It appeared to me to be part of a “storage locker sight unseen contents buy”.    Afaict this is just the mount , no electronics seem to be included, or CW shaft.    (Btw The CL post also had a 13” red tube Coulter dob that iirc appeared to me to be overpriced.)

This blurb is included in the 400QMD eBay post:
“”It does not include a additional parts or accessories.“”

¯\_(ツ)_/¯

Connecting ASIAIR Pro to a CP4 - Mach1

Lee Decovnick
 

Hi all,

This is my first post, though I’ve been a long time Mach 1 (CP3) owner and I just bought a second used Mach 1 (CP4) for my wife. We shoot astrophotography two weeks a year on the Modoc Plateau, 50 miles east of Mt. Shasta.

The ASI Air Pro mount interfaces is pretty basic, which is fine as she moves up from shooting the Milky Way with a DSLR into using the ASI CMOS cameras.
So far I have had tried Ethernet and USB and Wi-Fi to talk to the ASI Air Pro, nothing. I can see the GTO WiFi network ,but no handshake with the ASI. But I loaded the FIDI driver and at 9600 baud, the RS232 serial port does connect, but drops out often.

I’m running the ASIAIR Pro App on a Windows 10 machine ( larger screen) - rather than an iPad - using Blue Stacks emulation..a pretty nifty set up. I do not have APCC loaded on my Window machine, do I need to do so?

Am I aiming for a bridge too far? I’m accustomed to simply shooting astrophotography just using my hand controller for the GOTO’s and I have no tracking problems with 2-3 minutes subs without PremPro. I polar align in the field with a RAPAS. Easy-peasy.

Suggestions and comments welcome.

Re: Losing Communications with the Mount

Steve Reilly
 

To add to Ray's post, we had issues with the scope at SRO which was wired (CAT5) but through a switch instead of the direct computer connect. When I discovered this I had the guys at SRO wire the mount directly to the 2nd LAN connection on the computer. Of course the IP address of the CP4 had to be discovered and the address used but since there hasn't been a single COM error. Worth the effort if not wired from computer to mount even if a second LAN connection is only available via an addon card. Our motherboard had 2 native LAN connections.

Hi Alex,

Today I started playing with APCC and started to define the horizon,
and it happened again. APCC displays NO RESPONSE FROM MOUNT in the
telescope position section. I also get no response if I try to
connect to the mount via a browser. Pinging the mount’s IP address also fails. I can only get communications with the mount if I power cycle it, at which point APCC re-establishes communications.
If the mount won't ping, there could be a network or power issue.

Are you directly connecting the computer to the mount? Or, is it going through a network router/switch/hub?

Try replacing the network cable(s) and any hub/switch.

Also, try raising the timeout value slightly in APCC. You should not need to go over 300 msecs for most requests. The mount will respond to most requests very quickly, but depending on the performance of your computer, the responses might not make it back through the network protocol stack to APCC before a timeout occurs.

Lastly, try switching the network protocol type. In APCC, if you are using UDP, try TCP instead, or vice versa.

-Ray

Ok, I’ve finally have some time to start playing with my new 1100, and
I’m having an issue with losing connection with the mount. Everything
would be going along, and then the driver starts complaining it can’t
communicate with the mount. Today I started playing with APCC and

NO RESPONSE FROM MOUNT in the telescope position section. I also get no response if I try to connect to the mount via a browser. Pinging the mount’s IP address also fails. I can only get communications with the mount if I power cycle it, at which point APCC re-establishes communications.

I’m not using a USB connection to the mount. I’ve directly connected
to my network via ethernet, as well as connecting it to my WiFi. I
have APCC setup to use the direct ethernet connection, so WiFi issues aren’t the problem.

The last time this happened, the mount was simply tracking during an
exposure and communications failed about halfway through the exposure.
It’s clear from that exposure during the failure that tracking stopped
as the stars started streaking. I got the mount and downloaded all the software last week, so I assume I'm all up to date on that account. The PC has windows 10 Pro and the latest updates.

I’m at a loss as to what might be going on. Any suggestions as how to troubleshoot this?

Re: 1100GTO case

skester@...
 

Sure thing:
The RA axis and CP4 are in the 25” XL #024 : 
https://condition1.com/products/25in-storage-trunk-ip67

 

The Dec axis, counterweight shaft and RAPAS are in the 25” XL #289 : https://condition1.com/products/dji-phantom-drone-hard-case

While they make good cases, Condition 1's website excels at making what you are looking for hard to find.

Re: Recurring error in AP V2 Ascom driver: "One or more valuesare out of range: LatSecondsLngSeconds..." #ASCOM_V2_Driver

Steve Wilkins
 

Hi John,
Looks like I may have solved this. I checked Windows number format settings and for some reason the decimal separator field was blank. I changed to . (period) and the error does not seem to be showing up again.


Re: Recurring error in AP V2 Ascom driver: "One or more valuesare out of range: LatSecondsLngSeconds..." #ASCOM_V2_Driver

John Upton
 

Renan,

   From the screen shot that Steve Wilkins reposted, this looks like it may be an internationalization error between the software and your number entry.

   If you live in a country that uses the comma "," as the decimal separator but have Windows set to use a period "." as the decimal separator, you will get just this sort of error. By entering whole numbers only, the error is avoided as you found. It can also be a problem with the reverse -- that is if you enter a period and your Windows installation is set for international format with a comma, then the same error will happen.

   Try entering the decimal point in both formats and see if the error continues. If it does, maybe Ray will need to look at that section of code to make sure the conversion to decimal matches everything else.

Do you mind sharing the case model on those two? I looked up a couple cases on the Condition1 website but the depth seemed close for the RA.
Thanks again

Here is a jpg showing the lat/long error in blue. The elevation is also wrong - was saved as 9m not 90m.

Both these errors have been corrected and the site saved, but still show up on reconnecting.


APPM Command Line Switches

W Hilmo
 

From the version history, it looks like APPM added some command line switches in version 1.7.0.5.

Does anyone have a pointer to the list of switches and their definitions?  I don't see it in the help file or in a quick web search.

Thanks,

Re: 1100GTO case

skester@...
 

Todd,

I travel every time I image, and I'm using two cases from Condition 1 to transport my 1100GTO.  They have the pick/pluck foam and are working well so far.  I get everything minus the counterweights in the two cases, the CW's go in a tool tote from Home Depot.  With the counterweight shaft included the Dec axis case is slightly heavier (48 lbs) than the RA (45 lbs) even thought the case is smaller, but both are manageable.  I've seen folks put the entire 1100 into a single Pelican style case, but at 80+ lbs that was too much for me.


Re: 1100GTO case

mikela
 

Yeah it's heavy at 77lbs.  Putting the counter weight shaft in the other box lowers the weight to 64lbs...still heavy but manageable.


Re: 1100GTO case

Jeffc
 

The original post called for two boxes but since there are one box solutions I’ll leave this rather cost effective solution here.
(The downside of this solution is it is a somewhat heavy “lift”.)

This is from Lowe’s. I think it was like $20.
I estimate the weight to be about 40-45lbs.
I also have a G11 tripod adapter attached to the bottom so that adds to the weight.

I move this from the garage to to car using a furniture dolly (platform with four casters).

This fits in a Model 3 w/ losmandy HD tripod and 12” SCT (and room to spare).
Since I usually (always?) setup near the car moving it at the site is not necessary. I do have to take it out of the car to lift the mount.


Re: 1100GTO case

midmoastro
 

THanks Mike. What do you estimate the total weight of that to be? I bet its more than I want to deal with so I would personally rather have two separate cases.
If I transport it to the backyard this would work. But if I travel to our farm in a remote location where its darker then I think I want two cases due to lifting it in and out of the vehicle.

Does anyone think the pick/pluck foam you get with a Pelican or other case would be enough to cradle the RA and DEC? Any other negatives to that stuff? tiny pieces breaking off, etc.?


Re: 1100GTO case

mikela
 

My entire mount sans counter weights is within the bottom 2 sections of this Rigid case system.  Bottom sections holds RA, DEC and CW shaft.

I have tried updating the site also in APCC in case there is a link to the ACON driver, but this does not help.
