Jerry,

Now I am lost I guess. Is the Configuration Management Tool what you were talking about in the video that I was directed to by Skull?

Hi Jed,

I would highly recommend using the PMC-Eight Configuration Management tool instead of using the manual procedure in the application note. It's much easier and much quicker and allows you to switch back and forth between wireless and wired mode. It will run on any machine you are going to run the ASCOM Client applications on.

Jerry, Skull & Robert,

Thanks to all for helping to clear this up & I kind of suspected that overall I would be better off to use the more secure serial connection. But it sounds that with this ASCOM will still allow me to eliminate the ST4 wiring between the guide camera & the mount using the pulse guide method with my PHD2 - that’s something at least. And then I would follow the video described connection through the POTH (whatever that is). And I would follow the workflow diagram on the PMC-Eight Application Note to go from ExploreStars to the wired serial ASCOM driver by switching from UDP/IP to TCP/IP using the “ESY” command; then switch from TCP/IP to serial using the “ESX” command. Whew!

Hi Skull, Jed,

You can use the ASCOM PulseGuide method via PHD2 Autoguider software  by selecting "ASCOM" instead of "On-camera" as the interface. PHD2 connects through the POTH and if the PMC-Eight ASCOM driver is set to wireless you will be autoguiding wirelessly, no need for any cables. It is more reliable to use the serial USB wired connection versus the wireless connection, but it can work.

Yep.  We've had a number of posts from folks who liked the idea of wireless, struggled with guiding over it, and then when they switched to wired, life became a lot better.

If you're guiding, you're setting up a near-real-time closed loop system.  If you're on wifi, you have risk of latency and dropouts that can mess with your closed loop...

Hi Jed,

If you want to autoguide without ST4 but with ASCOM you must go the wired way I believe.
Correct polar alignment will be important for success, so you need the optional Azimuth Adjuster Adapter if you don't want to spend ages achieving it.

Using WiFi and ExploreStars can get you a reasonable virtual alignment though, but you have to autoguide over ST4. 

WiFi is less reliable for the serial connection I'm told.

Not sure what discussion about the POTH Hub you are referring to atm, I should watch the video again for that but that's not an option for me at this moment. 

Clear skies!


I did the polar alignment, but then how to align on 2 or 3 stars..??

Kevin Rea <reakevinscott@...>
 
Edited

Hi guys,
I am using Astro Photography Tool....
Ok, I did the Polar alignment on my EXOS-2GT PMC 8 mount, and after I had it aligned in the polar scope, I set both parts of the mount to the arrows, I believe this is the home postion.
But now what ??
I switched over to the Explore Stars app to do a 3 star alignment, but when I told it to slew to one of them, it was way way off, like the other side of the sky..

What is up ??
In my old celestron 4se , it walked you through each step and stored each step as you went.. It worked very easily..

If you guys wouldn't mind helping me again.

I am going to hook it all up again tonight..
Also, I noticed that when I went through and got the PMC-8 set to operate on the serial port instead of the wifi, that the Explore Stars application would not find the mount.
Is there also some trick to that ?

Also, I notice that the Azimuth Control Knobs don't seem to do anything, i have loosened both and then tightened one or the other, and it does not move.
The Latitude Adjustment Handles work just fine.
Also, I am guessing that the R.A. Setting Circle Dial is to set the Month ???  is this correct ?



thanks for your help again.

Re: External Power #EXOS2 #starparty #TECHNICAL

 

Jerry,
 
Don't know if you remember, but when I was in pre-purchase mode (long ago) and peppering you with questions on CN, I finally realized what you were doing with the Propeller chip...
 
I then accused you of "adequate overkill".  Still stands.  Well done.  :-)

Re: iEXOS-100 WiFi to Serial Question

Jed Orme <jedtorme@...>
 

Skull HQX or Kent,

I must admit to being confused about the WiFi capabilities of my iEXOS-100 & thought it was limited to only use with ExploreStars. Since my goal is the same as shown in the youtube video you provided, that is to use ASCOM to ultimately connect to Cartes du Ciel, is there any recommendation between using the WiFi option over using a serial connection? I understand there could be a problem if I was at a location with other WiFi interference, but could the WiFi connection also work for eliminating the ST4 connection between my guide scope & mount, using the ASCOM to provided this guide info or does that require using a serial connection between the computer & mount? Does the discussion on the video about the POTH Hub also apply in my situation? Many thanks for this help.

Jed

 Yes Skull,  I like to think that I know what I am doing most of the time, although the original designs did not include the reverse polarity protection, that was added just prior to the first delivered systems in December 2016. It is a little added cost, but on this level of instrument is absolutely needed for those doing DIY power systems.

Counter Weights #EXOS2

Timothy Myers
 

After a few days of slewing around with the new mount, I decided to put my 8" SCT on it to see how the balance was. Much to my surprise the Weights will not slide over the balance arm. It feels like there is a small ridge of material from the machining process that is preventing installation. Before removing that myself, I thought I would enquire here first. Yes I did remove the end stop first, and both weights do the same thing.

Makes you wonder why some manufacturers leave it out, probably to save a couple of cents.

Skull HQX,

Thanks much for this added info; I will check out the video as I think I understand the initial change needed but a bit confused about the second command to be given to get to serial use.

Re: iEXOS-100 WiFi to Serial Question

Skull HQX
 

You should probably watch this ES video completely: https://www.youtube.com/watch?v=f_gYiJnEU38&t=

It is more about ASCOM over WiFi, but it will make a lot more clear I believe.
At 11:38 there is some information about the application Rick just posted a link for.
With that application switching to wired will be easier.

Not a complete answer, but it will get you started I hope.

Clear skies!

Hello Rick,

Thanks much for the quick response but I am not sure I understand what to do with this zip file. I am communicating by email on my iMac which is my main computer. I only use a small PC laptop for astronomy related software, etc. So I think I can figure out how to transfer the file over to my PC but not sure what to do with it after I open &/or run the zip file. Will it make the needed changes in my PC to enable the serial connection or is there anything else I need to do?

Jed

iEXOS-100 WiFi to Serial Question

Jed Orme <jedtorme@...>
 

Hello Kent,


As you may recall, I recently purchased this mount & plan to use it primarily for astro photography rather than viewing with my WO Z61 telescope & attached ZWO mini guide scope & camera.  I plan also to use SharpCap for polar alignment.  I currently have it set up with a WiFi connection to my PC laptop to use ExploreStars, & have been experimenting with 2 & 3 star virtual alignments also.  But I understand that I can’t use the ExploreStars when doing long exposure astro photography due to field rotation errors, so I have downloaded Cartes du Ciel & the ASCOM driver for it to use for astrophotography work.  

Now I need to switch to using a serial connection instead of WiFi with my PC laptop, & also have downloaded your “ExploreScientific PMC-Eight Application Note PMC8-AN003 DOC-ESPMC8-AN003 Rev. 0.1 2019 January 12” six page documentation that explains how this must be done.  But based on its complexity, it looks like you need to be a computer programmer or engineer to accomplish this.  Is there some kind of video tutorial or anything else that the average person might be able to use to help with this?  I am planning on attending a star party event this weekend, but I am not going to attempt to make this change to using a serial connection with the USB A to Mini B cord that I bought to use for this until I can better understand how it is done.  What can you suggest please?

Jed Orme
