Question about Meade LX200GPS Telescope

1 Answer

Meade LX200GPS 8" won't initialize on power up.

My LX200GPS will now power up correctly. When I connect the AutoStar hand controller then power up the scope, one of 2 things will happen: the top row on the AS display turns to white boxes, almost like a progress bar) from left to right. When the line is full, everything just stops. The other thing that sometimes happens is the display just stays blank. The scope never moves. None of the buttons on the hand controller do anything. I tried connecting to an XP laptop via the serial cable adapter that came with my LPI and the left RS232 port, and the autostar software doesn't see the it.

Try doing either a garbage collect or a safe load-- and then reinstall the hand controller firmware--

Instructions-- depending on the type of controller
Autostar 495 or 497: You enter Safe Mode by holding the [enter] and
[scroll down] keys pressed when you power up the telescope. The
Autostar will say "Flash Load Ready"... now go start the ASU.

Autostar II: if you need to use Safe Mode to recover from a disaster,
turn on the telescope, and key 999 before it says "Initializing"
The Autostar will say "Flash Load Ready"... now go start the ASU.

LX200gps: BEFORE proceeding further, click on the OPTIONS item on the Top Bar.
Now click on "Garbage Collect Hbx" ... this will perform data cleanup
within the Autostar which will avoid potential mess-ups.

Can you tell me the communication setup for the xl200GPS MEADE 8 inch telescope. Like the comm Port number along with the other settings. Thank You.


If you mean the LX200GPS from Meade, http://www.meade.com/manuals/505ccs/index.html#tc gives the following settings for the AutoStar RS-232 Serial Com Port:
Baud Rate: 9600
Data Bits: 8
Parity: None
Stop Bit: 1
Flow Control: None
http://www.meade.com/manuals/autostar/apb.html has the pin assignments for the 4-pin and 6-pin adapters that connect to the RS232 cable.
Most versions of Windows from WIn95 on will automatically assign the serial port an unused IRQ port if you add a add-on card to a PCI or PCIe slot. (USB to serial port adapters should be able to do something similar with the above data.)

I hope this helps.

You can try Three things:

1. Do you have fully charged batteries-- or a good power supply.

2. Sometimes the cable to the hand controller needs to be replaced

3. Execute a RESET on the hand controller and reload the firmware--

If these do not fix it, the hand controller is defective and must be replaced. You can find a used 497 controller for about $80 on AstroMart.com

and Meade can also sell you a new one.

I have a broken autostar 2 telescope controller and need a replacement but can not find one in the UK


Many Meade dealers can order you a new hand controller, either Autostar II, or the 497 controller. Contact a large telescope dealer in the UK, or you can order direct from Meade here:

My telescope/autostar not working ,will only display startup info on handbox ,then nothing happens !.


This is sometimes caused by a bad hand controller cable and or corrupted firmware in the hand controller.

Get a new cable first and try it-- if this does does work then RESET the hand controller and reload the firmware using the proper computer cable and Autostar Updater Version 5.9 available here:

Before you panic, try a new hand controller cable. You can buy these from Meade or for a better one from www.scopestuff.com

"Autostar II: if you need to use Safe Mode to recover from a disaster,
turn on the telescope, and key 999 before it says "Initializing"

Can't upload data from computer


Check and define/ assign your com ports thru autostar and consistantly use the same port everytime you connect.
Also some usb to serial adapters are unsuitable ; dont ask me why but some work with autostar and some just dont, belkin adapters almost never work but the keyspan brand works reliably. I had the same problem and the kspan adapter plus comport set up sorted it.
Hope this helps
