I am trying to use the Celestron PEC tool to do a batch PEC analysis on my CGX-L but cannot get the PEC tool to connect.  In the pull-down menu it gives me two options:  1) NextRemote - this is from my previous use of the tool with my CGE and does not work with the CGX series; 2) COM13 - selecting this does not work.  There is nothing connected to my computer on Com 13.

 

I have the mount connected to my PC using the USB input to the bottom of the hand control and with CPWI running on the PC and connected to the mount.   This is how it should be done.  I checked the COM ports on my computer and it shows the connection to the hand control with the internal USB to Serial adapter indicating this is on Com port 3, but typing that into the PEC tool pull down menu item does not work.  I tried typing several different Com port numbers in the PEC tool pull down menu to no avail.

 

From other threads it is clear that this can be done, but the threads do not address my problem.  Any help would be appreciated.

 

Regards,

Curtis

I have not done this yet myself, so I may be full of hot air.  Have some salt on hand.

 

The difference between NexRemote and CPWI is that NexRemote provides a virtual com port to connect other software to, CPWI does not.  CPWI "uses up" the com port and only provides an ASCOM interface to connect with.  The PEC tool wants to use a serial port, so with CPWI in the mix you are out of luck.  If you don't run CPWI I believe you will be able to connect the PEC tool to COM3.  After doing so, just train the PEC like you normally would.  When you are done you can reconnect CPWI and enable PEC and you should be good to go.

After a delay due to surgery,  I was able to confirm that I could connect the Celestron PEC tool to the mount through the base of the hand control without CPWI running at the same time.

Yep, this works. But I could never get it to do a 5 cycle average. PEC Tool would crash.

I was able to use PECTool with CGX-L by connecting into the HC and using NexRemote along with the normal celestron ascom guider - and no use of cpwi.  I was able to train with many cycles in the PECTool and load the curve into the mount.  After that you can just use CPWI as usual and playback the curve you recorded.

PECTool doesn't work with high com port numbers. Try a com port in range 1..4.
