Subject: Problems connecting a laptop to a LXD55 and getting Autostar suite working Date: 3/26/04, 10:53 From: Lankreijer-Kroon (jam.lankreijer@quicknet.nl) I have read all the relevant entries on your wonderful site and I have tried all the suggested solutions but nothing did work in my case. I have a Windows XP laptop without a serial port, so I have to use a USB to serial bridge cable. I bought one (brand unknown, but certified) in the local computer shop. The Meade cable has no official product number so my retailer here in the Netherlands has an ordering and delivery problem. When I connect the telescope to the serial port on my desktop PC, (without the bridge cable), autostar suite works fine. I took the opportunity to update autostar to version 3.1E. However, when the telescope is connected to my laptop, autostar is not recognized. The ASU automatic search option does not find a COMport, although my laptop says that the virtual serial connection is working fine. When I use the 'test com.port' option in Autostar suite, I do get replies but nothing more. These findings give me the impression that the bridge cable is the problem. Or am I missing something ? Is my problem solved with the official Meade cable ? Am I facing a hardware or a software problem ? Can a software problem be solved with a downloadable patch ? Thanks for the possible suggestions, Jos LankreijerMike here: Did the USB converter have a driver? All the ones I've seen require them. I've used the Keyspan USB-serial converter with its driver on my Macintosh and it works fine to communicate with the Autostar.
Subject: Initializing Remote Handbox Date: 3/26/04, 08:38 From: n01sci2 (Webmaster@101science.com) I finally got Autosuite's Remote Handbox to work - that is to show the Autostar Tree in the left window - using a serial COM port. This only happened after I upgraded the Autostar to version 30Eb from my original version 26ec. Funny thing there was 30Eb was on my hard drive and I could not get to the WWW site so I just used 30Eb on my hard drive. I don't know how it got there. Now on to my problem. I went into menu Telescope, Communications Start Network Server. The next window come up saying scope port 1, dome port 2, and network port 5401. Status is saying idle. In Windows XP I went to START, settings, network connections, Local Area Network 2 support tab, and I see an IP address of 192.168.0.100 so I assume this is my computers IP address? Yes/No? Then back to the menu Telescope, protocol, Remote Handbox window. There I set the IP address to 192.168.0.100 (the default address that was in the window would not work). Now I check the connect box and immediately get a connect forcefully rejected error message. I now go to the Net Scope window and check the LISTEN box. It says it is listening on 5401. Now back in the Autostar Remote handbox window I check the connect box. Net Scope now says it is connected to 192.168.0.100 and in the Remote Handbox window on the left it say Austostar Menu and the word Initializing is in the top log window. But nothing else happens. I use the real handbox keys to try to get it to respond like it did when using the COM port but nothing happens. Any ideas? Am I still using the wrong IP address? Where exactly can I get the right one? LarryMike here: First off, I suggest updating to 3.1Ee from Meade's web site. The older version could even be the source of the problem. You might also want to read my article "Autostar Suite on a Macintosh" on the Autostar Info page; I mention some similar problems that I had when I first used the Suite.
And an update:
After 6 hours of working with this problem I got it figured out. My Autostar is on COM Port 2 of my computer. Therefore in the Net Scope window the "Telescope" port must be set to "2" to match my COM port in use in my case. Now I am connected using the network just fine. They should relabel the Telescope Port to - Telescope COM Port - in my opinon as this would have saved me 6 hours of struggling. Anyway now I can try again to get some LPI pictures. I agree with you and others here that they need to provide some sort of zoom capability with the LPI camera to get in the ballpark first instead of such high fixed focal length. Thanks again for you site ant all the help on it. Larry Dodd ledodd@bellsouth.netAnd more:
Yes I did get it to find the updater on the WWW so I am at 31Ee now. Your article was VERY helpful for sure to help me step through it all. By the way you mentioned that you wished it would slew slower and it will if you set the slider marked "Slew Rate" on the virtual remote handbox but I imagine you know that already now. Only thing I don't like about the network set up is one you mentioned in your article that you can't use the starmap to point to things as that feature is grayed out in a network configuration for some strange reason. Perhaps the thought was if multiple users were all trying to move the scope at the same time might be a mix-up. This should have an override though for one operator control but doesn't. Switching back to COM port sometimes won't work until you close everything and start over. Hope they work on the software and improve it soon. Thanks again. Larry Dodd

I must respectfully disagree... when you use the Autostar Suite between your LPI and the Autostar, it will happily Autoguide. If you run the normal Meade firmware in your Autostar, Autoguiding will only work in POLAR mode. If you apply my patch31e4 patch kit, that restriction is removed, and it will Autoguide in Alt/Az, too. This is telescope-model independent, so you can Autoguide ETX's, DS's, LXD's, 4504's and LX90s. The LPI/AutostarSuite accomplish their Autoguiding function by means of new instructions Meade added to the serial command repitoire of the Autostar. Therefore you need to be running firmware version 30Eb or newer. have fun --dickMike here: Thanks Dick. I stand corrected!
And:
Actually, you may get to sit down... Let me actually -test- this (i seem to remember hitting a "it didn't work" at one point, but that may have been the non-Polar factor) This will take a day or so to sort out (i don't have stars) have fun --dickAnd:
I look forward to hearing the results of your tests...... Thankyou both for your input. I had another question that arose today - do you know why the '70' has a 9 speed drive control but the bigger scopes only have 4? I would have thought the other way round would make more sense, given that higher magnification needs more sensitive control. An effort to keep costs down perhaps? Regards, DaveAnd this:
Your funamental premise is incorrect, or based upon partial info: The little default handcontroller (which came with ETX90's) can only do 4 speeds. I think the 494 Autostar might also have a 4-speed limit. The 497 Autostar can command 9 speeds from the keypad. It will do that to all models of telescope. The telescope motors themselves are capable of over 200 discrete speeds. Again, that's all models. The ETX70 to the LX90. The biggest models (LX90) cannot go as fast at "full speed" as the smaller scopes, but we're talking 6 degrees per second versus 8 degrees per second. All models are capable of 3 degrees per second. have fun --dickAnd:
Heh Heh, my newbie status making itself apparent once again! ;o) Thanks for the feedback. Regards, Dave
Subject: LPI an an ETX autoguider Date: 3/25/04, 13:44 From: David Mason (dave_mason@totalise.co.uk) I have been reading your LPI pages with great interest, as I am considering an etx-125 or 105 in the near future. I am a little confused - after reading the LPI manual, I had the impression that you could use the LPI as an autoguider, as the software tracks your image and sends info back out to the autostar via the cable. However, I noticed that you gave a reply to Jim Beston on 6/3/2004 where you said 'Autoguiding requires an Autoguider. None available for the ETX.' (AutoStar suite User Feedback page). Does this mean that the software only tracks objects as long as they remain within the telescope's field of vision?, or just that the autoguider part of the software only works with other telescopes such as the LX200? I was thinking of using the LPI as an autoguider and piggybacking a camera for long-exposure widefield shots. I would be interested if you have any info on the exact autoguiding capabilities of the LPI with Autostar suite for the 105 or 125. Thanks for any help you might be able to provide - your site has proved hugely helpful to me already and I appreciate your work. Warm regards, DaveMike here: The Autostar "tracks" the sky; the LPI doesn't by itself. So, yes, you need the Autoguiding capability, which the ETX/Autostar doesn't have.
Subject: ETX and Meade LPI question Date: 3/21/04, 15:30 From: David Ryle (davidr@wf.net) I am wondering if the Meade LPI can be used as an autoguider for the ETX90EC with Autostar? Thanks for a wonderful website! -David RyleMike here: Not currently.
Subject: Re: Meade LPI Date: 3/19/04, 21:43 From: Dave Kutay (dk1@comcast.net) still confused if one connects to the telescope from the computer what is the other one for?Mike here: If you have an Autostar II, use the LX200 cable. If you have an Autostar #497, use its cable.
And:
hey thanks for the info. i did not know the Autostar was a controler i thought it was part of the software.didnot make much sence to me. thanks again dave kutay
Subject: Meade LPI Date: 3/19/04, 19:30 From: Dave Kutay (dk1@comcast.net) hi ive been trying to find someone to help with a quesstion about the Meade LPI it comes with two cables that look like a phone line one is flat looking and the other is round could you tell me what the difference between the two are any help would be greet trying to get intouch with meade but they dont reply. thanks for your time dave kutay Astrophotography by Dave Kutay http://dave_kutay.tripod.com/Mike here: As described in my article "Autostar Suite on a Macintosh" on the Autostar Info page, the cables are a a LX200 Serial Cable and a #497 Autostar Serial Cable.
Subject: LPI Autostar suite Date: 3/12/04, 15:27 From: Jim Beston (james.beston@btinternet.com) Can't seem to get the remote handbox function to work. Have made sure no other communications are open ("none" selected in the protocol). On selecting Remote hand box and checking the connect box "initializing" appears and nothing further happens?? Any ideas?? Thanks once more JimMike here: As I discussed in my article on "Autostar Suite on a Macintosh" on the Autostar Info page, "When I first brought up the Remote Handbox it would not connect to the Autostar. Oops, the Autostar Suite still had the comm port. This Remote Handbox is a separate Windows application so it was necessary to disconnect the Autostar Suite application from the Autostar before using the Remote Handbox application. Once that was done I was able to use the Remote Handbox..." Could this the problem you are having?
And:
I was aware of your article Mike. Updating the Autostar software version (from 26E I think) to 31Ee has solved the problem. It is now 18:30 hrs in the UK, the skies are (for once) clear so, once I've let a rather large dinner digest a bit I'm off out to see what I can see here by the sea! (Feeble joke!). Thanks for all your help Mike, you're a Star! Jim
Subject: Using Autostar suite for PC to ETX connection Date: 3/6/04, 12:15 From: Jim Beston (james.beston@btinternet.com) Having just had some success with astrophotography using the LPI Imager, I am now trying to set up control of my ETX 105 from my Laptop. The laptop has various connections, the most obvious of which to use is the LAN which I think is an RS232 socket having 6 connectors It appears that I need to connect the laptop LAN socket to the Hand box, the available connection on this is another RS232 type but has only 4 connectors. The LPI comes with two RS232 type cables one having two 6-"pin" connectors and the other 4 "pin". I'm totally confused. Obviously I nees some sort of an adaptor. Can you advise please? Grateful thanks, JimMike here: The #505 cable supplied with the Suite connects to a serial port on the computer, not the LAN (ethernet) port. The supplied adapter has a DB-9 connector. If your computer has only USB then you will need a USB-serial converter (hardware and software).
And:
Obliged Mike, My Laptop has USB, parallell, firewire, LAN, Modem and WiFi but no serial comnnection. I can connect from the Autostar handbox direct to the modem where the phone line would go. I thought this would do it as there is an option in the autostar suite to connect via a modem. Obviously I doesn't mean what I think it does.! I'm suprised Meade does not supply the USB connection it would save a lot of problems. I bet the converter costs an arm and a leg!! Thanks JimMike here: Belkin, Keyspan, and Meade have USB converters. I use a Keyspan one with my Macintosh. And no, you can't connect to the modem port; that expects to talk to a telephone.
And:
... To see if I can test the guiding of my ETX 105, I've just installed the Autostar suite on my desktop PC which has a serial port. I have used the supplied cable which fits into the Autostar handbox and the adapter. I note that the adapter has six contacts on the cable side but the cable connector has only four. On trying to set up the connection in the software using the "Autostar via comm port " option I get the error report "Invalid ACK response from LX200" I really would like to assure myself that the guiding works before I purchase the serial to USB converter (£40) to use the suite on my lap top! Can you advise again please? Thanks & regards JimMike here: Autoguiding requires an Autoguider. None available for the ETX.
And an update:
Its working Mike: All I did was turn off the telescope and then back on again. Off it went - nist have initialised itself! Pity about having to buy an adapter for my Laptop thopugh.Mike here: Sounds like you got the comm going.
Subject: suite Date: 3/4/04, 05:55 From: spirosvlx (spycron@freemail.gr) thanks first. I recently received the autostarSuite and dowload the manual from meade site.this is not the same with the manual the cd has. new manual version from meade site{ 3.12} says that ......at starmap section the viewpoint allows me tochange the possition in the sky. THIS command there is not in the program the cd Ihave.I upgrated the program but the problem is still here. any suggestions????Mike here: Yes, that function is not there. The manual is wrong.
Subject: ETX-70AT question Date: 3/2/04, 10:45 From: Alan_Brittain@cargill.com Do you know if the Etx-70 can be updated so it will run with the autostar suite? I purchased the autostar suite this winter and updated my LX200GPS 10", and it works great. But I was just wondering if the Etx70 will work the same way. I hooked the laptop up to it one day, just for fun. But it behaved about the same way as the LX did without the update that is needed. If you know thanks! Alan BrittainMike here: The Autostar Suite will work with the #497 Autostar, so you would need that instead of the standard #494 Autostar.
And:
Can the #497 Autostar work with the Etx70at, and can I buy it?Mike here: Yes and Yes.
And:
Sorry to bother you again, do I need to contact meade for this or can I buy the #497 from oceanside photo and telescope? Can you tell me who to talk to about this. By the way thanks, you have been a big help.Mike here: Dealers sell the Autostar #497 so OPT should have them. Here's the direct link on their website:
