Re: AP Keypad, sell it or not?

When it came time that I wanted to point it, the keypad was unplugged (because the keypad was set to auto initialize and I wanted the computer to do it).
When you initialize the mount with ASCOM driver, you can then hot plug the keypad in and it will come right up by itself in the Main Menu and not demand anything from you. How could it be any easier? The keypad can be set to anything (Yes, NO or EXT), but if you initialize with ASCOM, the keypad will skip all the initialize steps and go directly to the Main Menu. You can plug it in and unplug it at any time in your session without affecting anything.

Subject: [ap-gto] AP Keypad, sell it or not?

Hello Dear Community,

I hope somebody here can help me to decide in how to proceed with the following:

I purchased a AP Mach1 CP4 at the beginning of 2016 which has worked flawless so far. At that time I also purchased the GTO Keypad however, I just used it once during the initial setup of the mount. Since then, I've used a computer to control the mount via AP ASCOM V2 driver.

In this case, I am thinking in selling the keypad to fund other astronomical equipment. However, before doing this, may I ask to the community: Is there a case where I would need the keypad in the future?

I am fully mobile (so far) and just interested in astrophotography and as I said, I always use a computer to control the mount.

Thanks and clear skies,

Diego

I see little need for a keypad in a permanent installation. 

HOWEVER, for a mobile setup, you may find the KP easier to use for initial star alignment than a PC or tablet/phone app.  

Also, having the KP as a backup at a field site, in case of glitches in other equipment would be convenient.

I was hoping you were aware that you might not be able to use 5.10.xx if you are in Europe so your only other choice is apcc
1.5.0.20 and driver 5.09.xx. I sent you a private email explaining how to get those versions.

Thank you Ray,

I don't understand why I have to install the last version 5.10.02 because I'm leaving in Europe (France).
I respect your recommendation in installing the precedent version 5.09.09, main reason.

I confirm it is not working (same troubles) with two last versions (5.10.02 and 5.09.09).
I confirm I swapped "," and ".", initially.

What could I do, please ?

Rémy







Hi Remy,

The problem is that you are using a version of the ASCOM driver (v5.09.09) that is not recommended with the
version of APCC that you are using (v1.6.0...3).

You will need to upgrade your ASCOM driver to v5.10.02 or downgrade APCC to v1.5.0.20.

Re: GTO Keypad

Joe Zeglinski
 

Hi Diego,
 
    I would NOT sell the Keypad, even if you almost never use it.
Fact is, odd things with the mount controller, and the Keypad provides you an alternate I/O device which can be used to test the controller and operation of the mount. A PC can really screw up, even a Win-10 Update can cause software to stop working suddenly. The keypad is independent of software, and is the most basic device to check out your mount.
 
    Also, there are times when using the PC to move the mount around,. like when re-greasing the gears can be messy possibly getting grease on the PC keyboard or mouse. Besides, I find it a heck of a lot easier to jog the mount a bit, when I want to move it for checking something. Using the PC is an enormous hassle in such cases.
 
    Besides, if you use the scope visually, it is far easier to jog the mount to center a star in an eyepiece than going back to the PC – jogging in the eyepiece FOV using a PC is impossible. Even if you use a tablet or a smartphone, you still need to look away from the eyepiece for that operation, Meanwhile, you can learn to feel the positions of the slew buttons on the keypad and jog the mount without moving your viewing through the eyepiece.
 
    The only other method would be using “voice commands” to a PC with voice recognition app, and train it for your voice, and AP CPx command set. as the way the old (no longer available) “Digital Sky Voice “software was used.
 
    Finally, there are mount tests, like a yellow/amber LED coming on, when the servo has a problem. The keypad is the best testing device.
 
    When everything else has been tried, this basic device, which doesn’t depend on PC hardware, or operating systems, is the easiest to test with, and the one whose results can be believed by tech support.
I think it would be foolish to sell the keypad.
 
Joe Z.


AP Keypad, sell it or not?

Diego Gomez
 

Hello Dear Community,


I hope somebody here can help me to decide in how to proceed with the following:


I purchased a AP Mach1 CP4 at the beginning of 2016 which has worked flawless so far. At that time I also purchased the GTO Keypad however, I just used it once during the initial setup of the mount. Since then, I've used a computer to control the mount via AP ASCOM V2 driver.


In this case, I am thinking in selling the keypad to fund other astronomical equipment. However, before doing this, may I ask to the community: Is there a case where I would need the keypad in the future?


I am fully mobile (so far) and just interested in astrophotography and as I said, I always use a computer to control the mount.


Thanks and clear skies,

Diego



Re: Differences in DEC Ascom and APCC screens

Thank you Ray,

 I don't understand why I have to install the last version 5.10.02 because I'm leaving in Europe (France).
I respect your recommendation in installing the precedent version 5.09.09,  main reason.

I confirm it is not working (same troubles)  with two last versions (5.10.02 and 5.09.09).
I confirm I swapped "," and ".", initially.

What could I do, please ?

Rémy



 

Hi Remy,

The problem is that you are using a version of the ASCOM driver (v5.09.09) that is not recommended with the version of APCC that you are using (v1.6.0..3).

You will need to upgrade your ASCOM driver to v5.10.02 or downgrade APCC to v1.5.0.20.

Hi John,

The AP encoder mounts use a set of high resolution absolute encoders from Renishaw. They are the gold standard for encoders and are extremely accurate. The encoder wheel has 64 million individual addresses or positions that can be commanded, which means it has a resolution of 0.02 arc sec. Once the encoders are turned on, which is the normal state of operation, nothing else needs to be done, either at startup or shutdown by the user. The encoders will remain on forever unless the user chooses to turn them off, which is not a normal state of operation.

With the encoders reading the axis positions, the loop between the servo and the mount's RA/Dec shafts is established down to sub-arc second accuracy (closed loop control). Therefore any command to move by that small amount will be faithfully produced on each axis. This provides the ultimate of control of your mount, all worm gear errors go away on both axes. 

Software programs such as APCC can set tracking rates in each axis to extremely fine levels and they will be followed exactly. For instance, if the tracking rate in a certain part of the sky needs to be 1.0001 times the sidereal rate for zero drift, the encoders will follow that rate exactly, and any worm gear errors are not in any way affecting that rate. Same is true of the Dec axis. In fact, anything that might try to alter the commanded rates such as a wind load on the scope tube is instantly countered by the encoder loop. Closed loop control means that anything that opposes the action on the mount axes (internal or external) is instantly opposed by the encoder loop. This is similar to the way direct drive mounts work.  

The encoders also allow you to establish a home position anywhere in the sky and tracking/slewing limits according to your telescope needs.. The home position is used to re-establish perfect pointing should the mount be lost due to user error. For instance you slew the scope to Vega and sync on Castor. Now the mount is pointed at Vega but the controller has been told that it is pointing at Castor - an obvious mistake but one that can occur due to user error. All subsequent slews will be wrong and the mount seemingly is lost. A simple "Go Home" command sends the mount to the home position and automatically re-calibrates the mount to that exact point in the sky.  

The startup sequence is exactly the same for encoder mounts and non-encoder mounts. The encoders fade into the background and operate seamlessly, no actions needed by the user. Upon startup, there is no need to find home because the positions of the axis are always known due to the nature of the absolute encoders (each position down to .02 arc sec is a unique address on the encoder wheel). When power is established, the servo controller simply looks at the encoder address and thus establishes where it is pointing. All the user does is to "Resume from Present Position", the servo takes care of the rest. At shutdown, the user can send the mount to any one of the pre-established Park positions, or to Home, or to simply leave the mount wherever he chooses and just turn off power. The mount will bed down and wait for the next session.

All subsequent slews will be wrong and the mount seemingly is lost. A simple "Go Home" command sends the mount to the home position and automatically re-calibrates the mount to that exact point in the sky. 

The startup sequence is exactly the same for encoder mounts and non-encoder mounts. The encoders fade into the background and operate seamlessly, no actions needed by the user. Upon startup, there is no need to find home because the positions of the axis are always known due to the nature of the absolute encoders (each position down to .02 arc sec is a unique address on the encoder wheel). When power is established, the servo controller simply looks at the encoder address and thus establishes where it is pointing. All the user does is to "Resume from Present Position", the servo takes care of the rest. At shutdown, the user can send the mount to any one of the pre-established Park positions, or to Home, or to simply leave the mount wherever he chooses and just turn off power. The mount will bed down and wait for the next session.

I'm looking at mounts in the 1100 GTO, MX+, DDM85, GM2000 range and I'm trying to understand how the 1100GTO encoder product is different from the ASA or 10Micron product.  As I understand it those two products only really benefit from encoders if you have built a model with custom software (effectively ProTrack)?    With AP it looks like you can do this with APCC Pro but you would still get the benefit of the encoders by just turning them on?  What does the startup sequence look like for an 1100GTO vs. 1100GTO with encoders?  I'm used to the MyT startup of home and then go as long as the mount hasn't moved.

Hi Remy,

Have you tried changing the Windows localization to USA format?

Also, if you haven't already please send us in private email your log files zipped with the APCC Log Zipper utility.

Hello Howard,

after performing the procedure you told me, after uninstalling / reinstalling the soft ascom AP V2 ( and some older
AP V2 Ascom versions ) and APCC , the same malfunction with the same symptoms: the indication of DEC do not
vary and remain the same regardless of the values in RA and DEC.


The mount moves well on the selected target; the RA value on ascom window is good but the DEC value (ascom
AP V2) remains the same regardless of the selected DEC.......

Help please, I don't understand what's going on.

First off, if I remember correctly from our remote session, you are not in the latest versions of either APCC
or the driver. I would update to the latest as a first step
Second. I have seen similar things a few times before, but it is not common. Ray may want to clarify, but if
I remember correctly, it is usually a timing issue that somehow gets out of hand. Here are a couple things to try.

1. If you can set the cursor refresh rate in your various programs (As you can in TheSkyX), set it to a
slower rate. This will help reduce COMS clutter and keep the buffers clear.
2. If this happens, click the disconnect button for the driver at the bottom of the APCC main page. Wait
about 2 seconds, and then reconnect. See if that clears the problem.
3. If #2 doesn't work,

1. Disconnect the telescope in the problem software
2. Disconnect the Driver in APCC
3. Disconnect the mount in APCC
4. Wait 5 seconds
5. Reconnect APCC
6. Reconnect the Driver
7. Reconnect the client software

Let me know if this helps.
