[SOLVED]Failure connecting to LX90 to autoguide.

Greetings....
I am having failures connecting to my Meade LX90 so i may autoguide....
If i understand the documentation right,i should be able to image and autoguide internally using the same "ASI 1600MC-Cool"....(I was successful connecting and imaging with my ASI 1600MC)I am fairly certain i have everything hooked up correctly(Imager cable to laptop)(RS232-to-USB cable from my LX90 #497 ETX Autostar controller to my laptop USB port)....I am not sure how the imager communicates with the telescope for autoguiding?....Does the imager see the star drifting and relay this info to indi and indi relays this to the mount to correct it?....

This failure happens with all the LX90 and LX200 driver versions....
Here is the basic failure from the log....

indi_lx200autostar/indi_lx200autostar_17:24:48.log
DEBUG 48.148398 sec : Toggle Logging Level -- Driver Debug

DEBUG 76.269241 sec : Handshake failed.
WARNING 76.269260 sec : Communication with /dev/ttyUSB0 @ 9600 failed. Starting Auto Search...

I have studied the forums and have not been able to fix the issue which appears to be "Telescope is not responding to ACK"
I installed "Kstars bleeding edge" from your PPA,and it updates daily....
"dmesg" shows my RS232-to-USB cable at port /dev/ttyUSB0....
My user name is listed in the dialout group....
My LX90 controller is a #497 ETX Autostar....
I have attached logs and images from my setup....

My info:

Kernel-Linux 4.4.0-87-generic (x86_64)
Distribution-Ubuntu 16.04.3 LTS

Desktop Planetarium-Build: 2017-09-24T13:10:19Z
Version 2.8.4-Using:
KDE Frameworks 5.18.0

Thank you for any help....

Well for whatever reason, it can't communicate. Have you tried this under Windows?

Hi,
I have not tried under windows....I only have Linux installed....
I am starting to think it could be something with the Autostar #497 hand controller setup....
The second port on the bottom of the #497 handbox is the one i am plugged into....
I used to guide the scope in Windows xp....
Do you suppose i would benefit by reinstalling kstars bleeding?
Thanks....

This i resolved by purging Kstars bleeding, and then reinstalling Kstars bleeding....It just started working perfectly after that....
Thanks....
