I suggest you get the latest driver from the FTDI Website.
You want the VCP (virtual com port) driver. Here is the link to the Microsoft Windows FTDI VCP Driver:

Hi Filippo,

Yes, I suspected as much.

You performed the section entitled: 
"If you want to change the PMC-Eight WiFi RN-131 configuration then perform the following procedure:"

Unfortunately, you did not heed the warning in this section:
NOTE: Please refer to the Microchip WiFly Command Reference Manual located here: http://ww1.microchip.com/downloads/en/DeviceDoc/50002230B.pdf
CAUTION: You change these parameters at your own risk,

The section you wanted was entitled:
"If you want to change the interface from the default WiFi Port (interface 1) to the Serial Port (interface 0), do the following:"

What you did was perform a "Microchip" Factory Reset which returned the RN-131 module to the Microchip Factory default configuration. This configuration is set before we at Explore Scientific set OUR SPECIFIC PMC-Eight configuration settings.

Here is what you need to do to recover and get back to the "Explore Scientific" Factory Default:
(This is an excerpt from the Application Note AN002 which is included on pages xx in the PMC-Eight Programmer's Reference located here:
http://02d3287.netsolhost.com/pmc-eight/PMC_Eight_ProgrammersReferenceManual_Release2_2019_March_07.pdf

Please refer to the Microchip WiFly Command Reference Manual located here:
http://ww1.microchip.com/downloads/en/DeviceDoc/50002230B.pdf  for details about the following instructions
You must use the values in the Microchip manual for the "Microchip" default configuration values to attach to the RN-131 network SSID and telnet into the proper IP address with the proper port number. See the section in the Microchip RN-131 manual entitled: FACTORY RESET.

1. Connect your computer to the wireless network SSID of the Microchip SSID, whichever yours is. It may include the word "roving" or "wifly"
2. After connecting to the Microchip SSID, open up a Command Window and issue the command "ipconfig /all"
3. Look for the "Wireless Gateway value" under the "Wireless LAN Adapter WiFi" section. Record this value
4. Using Putty, TELNET into the IP address recorded in step 3 using port 2000 
3. You should be greeted with the *HELLO* prompt of the RN-131 module.
4. Enter "$$$", and you should see "CMD".
5. Hit Enter again and the version number prompt, i.e., "<4.41>", is displayed.
6. Enter "get everything" to obtain a list of all the current parameters and what they are set to:

At this point please post these parameters here on this thread so that I can see them.

YOU SHOULD NOW BE ABLE TO ISSUE THE FOLLOWING COMMANDS TO RESTORE YOUR WIRELESS TO THE "Explore Scientific" Default Values.

RN-131 WiFi Module Explore Scientific Default Configuration Setup Commands 
NOTE: It is suggested that you cut and paste each block of commands into the terminal and then manually type and enter the “save” command. Ensure you receive the “AOK” response after each command is entered.

Hi Filippo:



They both have a cd disk that you have to install the software for the chip. They both work well. From looking at your link it should work. If not you can always return it.

Hi everyone, 
I'm a proud new owner of an exos-2 pmc-eight.

I probably made a big mistake:
I wanted to update the firmware so I connected putty to the mount with WiFi. I switched to serial connection, but I think my serial cable isn't good (I inverted dtr) because putty, parallax or config manager wasn't able to connect. I was still able to connect putty on WiFi but I wasn't able to switch back to WiFi connection.

Here's the mistake.. I made a factory reset thinking I was able to set the explore scientific default values on WiFi cause it was still connected. At the first set command putty wasn't responding and now I'm stuck. 

Will I be able to connect with a good serial cable and set the default ES values or I bricked it in just 3 days? 

I bought a new cable on Amazon:
https://www.amazon.it/DSD-TECH-SH-RS232A-Adattatore-seriale/dp/B07MYYCMJT
Is that good? 

Sorry for my English, I'm Italian.
Any help would be great.

Hi Filippo,

Your system is not bricked.  Tell me exactly where did you get the information you used to do all these changes, then I can understand where you issued the factory reset as you called it. I have a good idea what you did, but I want you to describe to me specifically so that I am sure we are on the same page. If what I suspect is true, I can direct you to how to correct the issue.

Thanks

Re: Can EXOS2-GT PMC-EIGHT handle 200mm diameter f/5 newt? #EXOS2

Dan:

The system in the picture is the EXOS-2 PMC-8 and ES N208CF Newtonian.  I must admit I do not use this set up anymore because I have the G-11 PMC-8 and ES 127 FCD-100 refractor.  I was thinking about bringing it out of retirement.  

In the picture I mounted the PMC-8 box on the handle of the Newtonian and used plastic adjustable cable clamps with 3M heavy duty dual lock fastener tape. The tape was placed on the back of the clamps and on the telescope tube rings which allowed me to quickly disconnect and reconnect the cables.

As someone else mentioned the wind is not your friend with a Newtonian.  It does not matter what mount you use the wind will cause problems with astrophotography because a Newtonian is essentially a large wind catcher.

Also you want to use a dew heater on the primary mirror especially during the summer if you store your telescope in an air conditioned home and take it outside.  The primary will dew up almost instantaneously.   

One more thing....balance is key with a Newtonian.  You want to ensure you are balanced both horizontally and vertically at 90°.

This is probably a stupid question but does the Exos 2 GT with its drive belt system suffer from backlash and PEC?  Thank you.
Hi Wayne,

I was going back through the messages on the MAIN group and noticed that your question fell through the cracks. You may have already found the answer. The backlash on the EXOS 2 PMC-Eight is mainly in the worm/wheel mesh. The belt drive system smooths out the PE. There are a couple of main components of the PE in the system. The first is the 600 second fundamental of the worm period. This is based on the 144 tooth wheel/ring gear. The second fundamental is a 133.3 second period based on the 4.5 to 1 ratio of the belt pulley system. 600 seconds / 4.5 = 133.3 seconds. This is caused by any slight wobble that may be on the motor pulley. There are other harmonics of these fundamental periods caused by belt tension issues and other miscellaneous issues.

We recently did an OpenGOTO Community Live program talking about how to analyze your gear system using the guide logs from PHD2.  Here is a link to the video on YouTube:

Re: ASCOM Freezing iEXOS 100 PMC-Eight

Lloyd Simons <simonsl23@...>
 

I guess I would need more information about you setup to determine what might be the problem. One possibility is if you try to connect the mount driver to more than one piece of software you will have issues. Only connect to mount to POTH and then connect your individual programs via POTH.

I love living in MI but the permacloud on the west side makes AP difficult. 😁

Hi Lloyd. I see you're in Michigan. I'm in Clinton Twp, MI, about 45 minutes outside of Detroit...and about 20 minutes from Chuck of Chuck's Astrophotography. :)  Nice to see some local boys here.


Re: ASCOM Freezing iEXOS 100 PMC-Eight

ToddB
 

Thanks for the replies. For posterity...

Initially, I was using ASCOM 6.4 and it was constantly freezing. Then I read a post where someone said to point to POTH from Carte du Ciel and other programs, and POTH to the driver. This helped a great deal, but I was still having several freezes per session. Then ASCOM 6.5 came out, so I updated to use that. The freezing persisted in about that same amount. That's when I started wiping my hard drive clean (3 different times), and eventually bought a new computer and installed ASCOM 6.5. Problem has persisted.

One thing I've noticed is that the freezing is more persistent if I am running the Celestron Desktop Focuser program. But even if I'm only running ASCOM, I get the freezing.

I've uninstalled ASCOM 6.5 and loaded 6.4. I'll try it tonight to see if it helped.

Again, thanks for the replies.

Todd

Hehe sorry I didn’t mean to offend you.  

Yes the polar scope must be collimated to the ra axis of the mount.  It is necessary for its line of sight to be a true indicator of the ra axis pointing...that is what you are trying to get pointing to the NCP.

I never could use a polar scope so I spent my out of the problem of polar alignment with a polemaster.   But if you want to use the polar scope you must get it collimated.  

The best way to learn how is to use google and find your self a video that you grok.  There are many.  This is a daytime procedure so you can get it done and not waste observation time.

Good luck.  If you get sick of it look into either an ipolar from ioptron or a polemaster.  If you care about polar alignment these will change your life for the better.

Thank you for your input! I will follow workflow as I just started at this crazy amazing hobby.
I found a youtube video that all it is Is white light for an hour, I used it with my tablet and it worked great as when I check the histogram its a solid line in tue middle.

Jennifer, I noticed you use APT, I just started using and at times plate solving has a hard time. I installed the 3 apps that it uses but I have noticed that only 2 are used. When I am having issues, I manually try the same image in All Sky Plate Solver and it does solve it but I am not sure if/how I can make APT use that one at those times when the other 2 fail.
do you know or have any other solution?

thanks you!

Hi Wes, are you saying collimation is necessary? If so can you explain how this is done please? I have tried by loosening and tightening the three little crosshead screws but apart from some minor movement in a rather random direction, gave up after about an hour of trying. There was no way I was ever going to achieve the objective of ensuring a centralised target remained so when turning the left right iEXOS 100 movement through 180degrees......
I know you to be a very knowledgeable and clever fella, I hope you can enlighten me!
Many thanks Wes,

Edwin:

Flats can be done the next day as long as you leave your focuser and lens untouched.  If your focus changed throughout the night it does not matter as long as +/- change was minimal.  You can use something like an iPad with a white screen  placed on the dew shield when the telescope is pointing straight up. My ES refractor’s dew shield tends to walk it’s way down on with the weight of an iPad, so I use a large rubber band directly behind the dew shield to keep it from moving.  You can sometimes get away with using a set of flats multiple times as long as any dust on the lens an/or camera sensor has not moved.
