I seem to have fried my AP900. Tonight, I set up to use the ST4 to

autoguide the AP900. I connected the relay cable to the autoguider

port on the GOTO control box (using the cable supplied with the ST4),

and everything else as normal. After I fired up the ST4, I turned the

power on my mount. The keypad lighted up ok, but won't slew and

I can't get past the Startup menu. The mount was working fine yesterday

(without the ST4) and was still set up from last night. I tried disconnecting

the ST4 and connecting a different keypad, but with the same result.

The light on the control box lights up, but otherwise the mount seems

dead.



Any advice would be appreciated.



Regards,

Bob Kuberek

What color is the little light on the control box? Since you were using the

mount the evening before the 900 "died," could it be your battery (if that's

what you use for power) died and not the mount? (E.g., did you turn off the

mount and leave a dew heater on?) Sorry for the overly simple suggestion,

but there is no category of simple goofs that I have failed to make.



I doubt it had anything to do with the ST-4... but is this the first time

you've used the ST-4? If so, are you certain you used the correct cable (or

did you make your own and use a standard telephone wire sequence?).

Hi Larry,



The battery was fully charged and I checked the voltage. I also tried switching

to a regulated power supply, and even checked the voltage on that.



I used the cable supplied with the ST4, assuming that it was compatible.

Here is what I've checked so far:



1. connections--motor cables ok, keypad ok, power ok

2. voltage--12.5 volts from battery, ok

3. tried swapping power supply to AC-DC 13.8 volts

4. tried swapping keypads for 2.3 version, switched mount type to AP900

5. tried swapping 12 V AP power lead

6. wacked the mount with a hammer



No joy. The keypad still lights, but freezes immediately when I go into

the startup mode or try to slew.

Bob K.

Sorry about your problem. None of the above will solve the problem. The best

way to determine what is going on is for you to give me a call with your

mount in front of the telephone (815-282-1513 9am to 5pm CDT, M-F). Have a

battery and a few tools handy, and I will go through a checkout with you. You

will be my eyes and ears, so to speak. I do not believe that a simple ST4

connection would cause the mount to quit. Swapping hand controllers will also

not do anything. It's the servo that's dead. When the servo is not working,

it will not communicate with the hand controller anymore, so you cannot go

through with the startup routines. We hope in the new version 2.7 to have

fault annunciation so that you will know if you have low battery, poor

connection to one of the motors etc.

We tested the mount yesterday. I took the cover off the RA motor and

confirmed that it was turning. AP asked for the servo box, which I have

shipped to them.

Took the AP900 out last night for the first time in two years to

bring in the new year and first light with the AP 10". The software

and ROM have been updated to current. I reset all local information

and did a two star alignment. However, whenever I tried to GOTO M42

or M37 I would get a "below the horizon" message. Any notion as to

what I did wrong?



Thanks

Check your time, date, daylight savings and location data. One of these is

off. The keypad tells you the RA number for the overhead hour angle. You can

slew to this RA number by entering it in the RA/Dec menu. The scope should

slew to the meridian. If it slews somewhere else, then you know that the

above time, date, daylight savings or location data is in error.

One other possibility is that the data base is corrupted. You can check the

RA/Dec numbers for the object entered and see if they make sense.

Again, check the data for the object that is below the horizon. If the

numbers don't make sense, you have a corrupted database. In that case, the

data needs to be re-installed.

#6433 Jan 11, 2003

Okay....this is strange. Last night I left my 900 GOTO in Park 3

with the power on and when I came back about an hour later the mount

was not in Park 3 position anymore (something seemed strange here).

I checked to make sure no one decided to experiment with the mount

(teenage boys in the area) and no one had. Further more, it began to

slew in strange directions - mostly with the DEC servo. For example,

the scope would whirl around like a helicopter blade moving from Park

3 to Park 1 (okay not entirely true - but the scope made more than

360 movement to end up correctly aligned on the RA shaft, but with

the scope pointing face down. I check the time and location to see

if they have somehow changed, and they were correct. I shut it all

down and restarted to make sure that everything was normal - no

effect. I figured that the keypad database might have been

corrupted, so I loaded it again. That didn't help - so I figured

that maybe I was too tired to figure it out so I shut it down (Park 3

and power off) and committed to reason it all out in the morning.



The best layed plans, as they say. When I went out this morning, and

powered up the mount........nothing happened. The red light wouldn't

even come on. Power checked power to the mount at the end of the

cable with a VOM - everything looked good, it just won't work! Any

ideas?



Thanks In advance for your help!

The red light is connected to the input of the servodrive. If it does not

come up, and the keypad does not light up, you definitely have a power

problem, probably undervoltage. Digital VOMs sometimes read totally wrong, so

I only trust my old Simpson voltmeter. The strange slewing can be a symptom

of a battery going dead. If the keypad does not light up, there is not enough

voltage. The keypad and servo are two totally isolated individuals that

happen to run off the same connector. The keypad does not get its power from

the servo drive circuitry, but directly from the input connector, so if both

parts are not working, then I would suspect that something is wrong with the

cable, or connector on the end of the cable, or the voltage is below 10

volts.



If you still can't get it to work with the proper 12volts applied, then send

the servodrive in for checkout.

#6438 Jan 11, 2003

Thanks for the response Roland!



Both the Keypad and Servodrive are out. I checked the voltage again

with a trusty old voltmeter and confirmed that I was getting 13-13.5

VDC at the connector end (but it is a brand new AP cable and

connector so I was pretty sure it good). I suspect it is a problem

with the connector/wiring in the Servodrive based on your

explanation....probably the problem that caused me to replace the

original cable (I was getting an intermittent open that seemed to be

related to the cable - though the cable tested okay). Anyway the

servodrive is off the packaged up for a trip to your shop on Monday.



BTW - as I was taking the servodrive off the mount I was struck one

more time by the thoughtful design and flawless execution of your

Company's products! I guess you've heard this a thousand times, but

it seems like each product you offer - from something as simple as

the QRBASE to the degree of perfection found in your scopes - sets a

very high standard in this industry for technical innovation and

attention to product quality. There is no question in my mind why,

in a world driven with the desire for instant gratification, so many

people are willing to wait for the chance to buy the best!



Thanks!

Just spoke with AP today. They think the next production run will be

towards the end of 2004. I got on the 900 list in Feb 2003; there's

one year's worth of people ahead of me, so if we make it in the next

run (a highly questionnable prospect), we're looking at at least 1 1/2

years. If we have to wait for the following run, then it's probably

more like 3 1/2 years (my estimate). To get back to your plan, based

on the worst case scenario, you could put aside 5 bucks a day for 3.5

years and be all set when (if???) that great day comes.

I have been on the list since Feb '02 and I was not notified in the last

Hi Don,



Good hearing from you again.



I suspect you had a rare Keypad connection problem - this one time.

Since the DC power was up and indicated stable, as was (eventually) laptop

communications to the mount, somehow the keypad was frozen, and may also

have caused Windows to crash. It sure is a strange combination of events,

especially since it did not repeat after tear down and set up again.



Maybe you forgot to actually "lock down" the twist lock on the keypad

cable, and the intermittent message signals were getting misinterpreted.

Strange that it would blue screen crash the laptop. Next time, check all

your cables, and possibly try a DC battery power pack, in case there is

flakey DC coming from the this Pyramid. This is dedicated to just the mount,

right?

Hi Joe nice to hear from you again too. While checking all my connections,I did confirm the key pad plug was in locked down properly. I had unplugged and replugged the key pad three or four times. Should it happen again(heaven forbid!)I will try the battery pack. I am taking my rig up to a friends acreage tonight and will try it out there. Hopefully you are right and it was a one time bad connection issue.

As an additional note, I listened to the RA drive to see if it was active after pushing the return from park button sequence thinking maybe only the display on the keypad wasn't working but the the drive was inactive.

Cheers

Hi Don,

There is ABSOLUTELY no way that the keypad or control box had anything

to do with the laptop crash. It is just a weird coincidence. Did you use

the same power supply in both cases?

everything inside and set it back up in the basement. After about an

hour, I fired everything back up and the mount and keypad appeared to

work fine. I fired up the lap top. Windows came back up with a message

that the system had recovered from a major problem (not exact wording).

I connected to the mount and brought up the Sky 6 and Pulse guide.

Everything connected and runs ok. I have tried several shut downs and

restarts with no further problems. My laptop (4+ yr old Dell Inspiron

8600) has always been stable.

Has anyone else experienced something like this.

Hi Don,

There is ABSOLUTELY no way that the keypad or control box had anything

to do with the laptop crash. It is just a weird coincidence. Did you use

the same power supply in both cases?

Last night I hauled my mount (May 2008 model) and scope out and set it

up in the back yard. After everything was set up in the normal way, I

turned on the power(Pyramid 5A power supply). On power up the LED on the

CP3 servo controller turned on red as usual however the keypad did not

come on. I turned off the power checked all the connections and cables

(keypad, motor cables power supply etc) then fired it up again. Again

keypad was still dead. I then connected my laptop via two keyspan USB to

serial adapters to the mount and fired up the laptop (Windows XP pro.

The laptop came on with the blue screen of death saying windows was shut

down to protect files on the computer. The were three references to

memory addresses in the last row. I shut everything down hauled

everything inside and set it back up in the basement. After about an

hour, I fired everything back up and the mount and keypad appeared to

work fine. I fired up the lap top. Windows came back up with a message

Sorry Marj disregard my last reply. I had the laptop power supply connected to the same three plug extension cord as the mount power supply. This was then plugged into the house. The laptop of course has its own batteries which effectively isolates the computer from direct connection to outside power no matter what it is. The only other connection to the outside world was via the USB to the mount. Coincidence?? Hopefully.

Thanks

Don

Hi all thanks to all of those who answered my email a while ago asking about

the Mach1 Goto scope capacities ,....after some thought and some pier

pressure ..:-), and the fact that my name came up for a 900 Goto I decided

on going with the philosophy ...go big or stay home.







Now I have the dilemma ATS.... portable pier or a Losmandy folding tripod

... my patio at the cottage is like standing in the joker's hideout (for

those of you who don't remember the batman TV series..... it's quite

crooked) due to the fact the cottage is built on a sand dune an it is still

shifting, so I am thinking that the adjustable legs of the Losmandy would be

better, but then what do I know..:-)







Any suggestions will be appreciated







Cheers

Hi Chas,



Congrats on your forthcoming 900GTO. I've had 2 ATS portable piers and can say without hesitation that they're excellent. They're very portable and set up in about 2 minutes. Their downside is the minimal leveling capability. The turnbuckles allow some leveling range but not that much. I always kept several 1/2" thick pieces of plywood with me to make up any additional leveling I needed. It was never a problem.



The Losmandy folding pier does look pretty enticing. Looks like it sets up quick, is very sturdy, allows a lot of leveling capability, and it's available for a pretty good price. It's on the bulky and clunky side though, in my opinion.



I think you'll be happy with either one. You might want to look at weight, foot radius, and wait time to make your decision.



Best,

Danny
