Question about Meade ETX-125EC (500 x 127mm) Telescope

1 Answer

Trouble shooting the telescope won't turn left and right using the electric controller - the Autostar computer controller. What should i do?

  • Anonymous Jan 08, 2008

    ETX-125EC won't turn on. It appears there is no battery voltage getting to the electronics. The slide switch appears ok from an ohm meter reading on the little circuit board. If I knew how to remove the printed circuit board mounted on the control panel, I could trouble shoot this problem further. I don't see what holds the board or the control panel in place, and how to remove it for servicing.



    thanks J.C.

ETX-80 hand controller say's "Self Check Failed"


You may need to reload the firmware by following these instructions for Safe Load:

From the Autostar 2.0 README file: "SAFE LOADER MODE IN YOUR Autostar:
If the firmware in your Autostar crashes and you cannot access the "DOWNLOAD" menu item on your handbox, you can use the "SAFE LOADER" feature of your new Autostar software (version release 1.1G and above). To get into the safe loader, follow these simple steps: 1. Make sure the Autostar and ETX are turned off.
2. Press and hold the "ENTER" key and the Scroll Down Key located to the right of the help key on the Autostar handbox.
3. While depressing both keys, turn on your Autostar power switch. This will require you using both hands.

You should see "FLASH LOAD READY" on your display. This indicates that you can proceed to Update new software to your Autostar."

This is for the 497 controller. There is NO safe load for the 494 controller.

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"
The Autostar will say "Flash Load Ready"... now go start the ASU.

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


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.

ETX-125 Autostar controller not working


I assume the small red light on the power panel is ON. ???

If it is the scope is receiving power--- check to make sure the cable from the hand controller is plugged in properly-- jiggle the cable to see if you have a loose BAD cable. Before you panic --- try another cable or reverse the ends ---

Before you buy another hand controller try a new cable-- scopestuff.com sells a nice long flexible one for the 497 hand controller.

Autostar


Double check the cable from the Autostar to the telescope. Sometimes the ends go bad. They can be replaced with regular telephone cables.

Computer control and pointing with NorthStar Goto & Autostar


Your reseller is correct. The wire (Meade cable #505) goes from an RS232 serial port on PC to a 4pin RJ plug. This plugs into the 2nd socket on the bottom of an Autostar 497 handset, the other socket being used for the curly lead to the telescope. So it goes PC to Autostar to telescope.

A common error is to try plugging the serial wire into an "AUX" ort on the telescope control panel - same connector. Not only does this not work, it can cause a lot of damage.

Wired like this you can control the scope from Meade's Autostar Suite (or many other planetarium softwares). You can also update the Autostar software to the latest 2009 version.

What else can go wrong? Well, many people want to control from a laptop, and modern ones don't have RS232 serial ports. Then you need a USB-to-serial convertor dongle, which effectively add a serial port to a laptop. But they often give it a very high port number (eg COM17) that the planetarium software does not find. Use Control Panel to reset the USB-serial-port to COM 1, 2, 3 or 4 and all should be well. But it can be a right fiddle!
