ETX-125 Autostar controller not working

Hi.
I''ve only used the telescope once, about three years ago and powered by AA batteries. It's been stored in a hard case (without batteries) since.
Recently reassembled the whole rig using only the mains power adapter (no batteries on board); telescope light comes on but not on the the autostar controller. It appears to be dead - no lights; no signs of life; nobody's home!

It was working fine before, although never been calibrated or "trained" in any way. I've only used it to move the scope.

I also do not have the means to connect the unit to a pc

Any suggestions?
Many thanks
Bill Barraclough

    Thanks Joe



    I'll give it a try.

  • billbarra Jan 19, 2009

    Still no joy!!



    Tried jiggling the cable; switching the cable around; testing the cable with an ohmmeter (cable is fine, incidentally).

    Tried using just mains power; just batteries; mains power and batteries.

    Still no sign of life.

    Power panel light is on, but nothing, zip, zilch, nada on the handset.



    Er......help!

    Thanks - not the answer I was hoping for, but helpful nevertheless: it confirmed my worst fears!

    I'll try to pursue another controller for testing from my dealer.

My ETX 125 did this to me,
here's what happened
I had a 497 autostar hooked up to it and it quit working
the scope stopped dead and the autostar went dead
i hooked another autostar up to it and the same thing happened
I took the scope apart and noticed that the wires for the upper motor run through the bolt that tightens the rotational clutch on the base, the clutch handle mechanism in the base sliced through the wiring and shorted out the 12v black wire onto the autostar data yellow wire, this sent 12v back into the autostar and fried it.

both autostar circuit boards were destroyed as the short caused the custom programmed microchip to burn and blister.

I am in the process of repairing mine and getting a new autostar computer.
I would recommend against asking a friend to try thier autostar box on your scope for obvious reasons.

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.

    www.scopestuff.com also sells the PC update cable so you can update the Firmware in the hand controller and add "Tours". However your computer must have a regular serial--- or you will need a USB to Serial adapter cable and driver, scopestuff also sells the USB-Serial adapter cable and driver CD--

    Call Jim at scopestuff --- he is really nice guy and will help you get these items.


  • Joe Lalumia aka TelescopeMan

    ok--- then you will need to get another 497 controller and see if it works ---- if it does then all is ok---- if not and electronic part is broen unside the base or the power panel. Do you have an astronomy shop nearby or an astro- club--- to get another 497 controller to test.??

The hand controller cable is probably defective-- right at the connector that plugs into the scope. Any computer network "wizard" can replace the connector. The wires must be in the exact same sequence when he repairs it.

If this simple fix does not work and you KNOW that the batteries are good-- then the hand controller is defective and will need to be replaced.

The contrast and brightness can be reset --- here is the manual -- how to do this is listed in the manual. If this does not repair the controller then you will need to buy a new hand controller-- the 497 hand controller is available used on Ebay from time to time.

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.

Power goes out ETX 125


Several possibilities:

1. Bad cable from hand controller to the scope. Buy a new one at www.scopestuff.com much better quality and cheap.

2. Firmware is corrupted in the hand controller. Update the firmware using the Autostar Update software here:
http://www.meade.com/support/auto/Au2ver59.exe

3. You have a bad hand controller and will need to buy a new one.

Never plug or unplug the hand controller or any other cables while the power is turned on.

Good luck--

Autostar


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

With the power off, check the connectors are properly plugged in at both ends. Like a network cable, the clip bit should spring out when properly located. Then power on. Within a couple of seconds there should be a long bleep and the display will show a startup message
( A U T O S T A R and Version number).

If that doesn't happen, and the batteries are fresh (and inserted the right way round), try connecting the curly cable the other way round (apparently that sometimes fixes it - personally I reckon it may just give another chance to plug it in correctly). If the doesn't work, you may have a faulty cable or a faulty Autostar or a faulty control panel. Take it back to the reseller to sort it out!
