Meade LX90 Guiding problem!
Posted 07 November 2013 - 11:35 AM
I have tried for months now to connect my LX90 to PHD via ASCOM but so far it refuse's just get error message "no instance of meade ex" I can control scope through Meade Autostar via " connect scope via serial cable" so usb and rs232 cables work and I could guide scope manually but is there another way to guide scope that doesn't need ASCOM? as I think this is the problem. The LX90 doesn't have a ST4 port and 909 ports are discontinued so thats a problem.
Any ideas please would be appreciated.

Serial guiding should work fine, though. Is it possible that you have the serial port tied up with the Meade software? It can only be used by one thing at a time. If you don't disconnect that software the port won't be available for PHD to use unless you add a virtual hub.

As for the 909 module, you neither need nor want it.

I believe you would use the Meade LX200 Classic ASCOM driver. Then you have to select this driver in ASCOM. Be sure and set you serial port or adapter like this:
Baud Rate - 9600
Data Bits - 8
Parity - None
Stop Bit - 1
Flow Control - None
This is how I guide my Meade LXD55 mount.

My setup is exactly like the bottom image, just wondered if I'v downloaded all programs needed, this is a summery :-
PHD Guiding (windows) v1.14
ASCOM Platform 6SP3
Meade LX200 Classic and Autostar #494, #495, and #497 driver (combined telescope/focuser, 5.0.4)
Meade Autostar Suite V5.50
Have also checked there all working on same com port (comport4)
Just said about Autostar Suit to explain that I'm getting a connection via USB/RS232 adapter otherwise wouldn't be able to use autostar remote goto? so why is it not connecting to PHD via ASCOM ???

What kind of USB to Serial converter do you have? Most of the cheap ones don't work!
Try running the Autostar updater, press the "Connect" button and see if it can connect to your hand controller. This will eliminate the ASCOM software and Meade ASCOM driver. If it works, your problem is probably in the PHD or ASCOM configuration. If it doesn't work, then it's with the USB/Serial converter or cabling.
