Switching Power Supply

Phillip H Coker <pcoker36@...>
 

Would a 13.8v 23a switching power supply be suitable for my AP1100/CP4? I operate only portable on a 100 a/h LIFePo battery but would like to have an AC backup power supply.

Yes sir. That’s what occurred to me.  Not sure what could have caused it as I hadn’t done anything since parking it.  I’ll box it up and send it in.

I should add that I plugged the keypad in and could never get it off the initial screen.

If you have reverse polarity the light won't come on.

I couldn’t get my meter to fit inside the little holes of the lock connector at the end of the cable that connects to the CP4. However, I unscrewed the lock connector (the solder points looked solid) and checked it there.

I’ve emailed George about my issue this morning but thought that if this is a simple fix perhaps I could save him some time. Last night, I got the dreaded “No Response from Mount” when I opened APCC. After checking com ports, replacing a cable and otherwise making sure everything was connected and in order, I noticed that there was no red or amber light on the CP4 after I turned on the power supply, something I’d never paid attention to previously.  The mount is an AP1100 AE-L. I’m not too adept at electrical lingo so I’m probably betraying my ignorance. The power supply and cable appear to be in working order. Anyone have any thoughts on what user error likely caused this.

Thank you very much Steve for your help.

FYI, this address (169.254.1.140) has never posed any problem of Ethernet communication since the reception of this AP1100-AE mount (sn: AP1100-003 acquired in 2013), both with the GTOCP3-AE and the GTOCP4.

But this problem has only occurred since the repair was returned to Astro-Physics ....

But now, not knowing the reasons why this address 169.254.1.141 is not suitable, reading nowhere in the Astro-Physics documentation any information on this subject, I would like to have all information on the type of static IP address allowing me communication via ethernet between a computer and the GTOCP4.

Should I do some engineering studies before acquiring such equipment .....? 

Thanks in advance.

Remy,

I am not familiar with your equipment since I have older (ancient!) components.  But the 169.xx.xx.xx addresses are not useable.  They are assigned when there is a networking error.  If you have a friend who knows networking, it would help to bring them in to look at all the components of your network.  In particular, the address for the DHCP server cannot be correct, it would not be a 169. address, and the mask is also not correct.  This stuff is all annoyingly complicated.  I would start by looking at other addresses in your network, particularly the router/switch which is acting as the DHCP server, and seeing what address ranges are being used.  Then I would manually set an address and mask in the correct range for the CP4, and the gateway, which is the CP4's access to the network.  Once you get that working, and have access to the DHCP server, you can try automatic settings.

This kind of issue is very difficult to debug remotely, which is why it would be best to get someone to help on site who knows something about networking.

best,
Steve

One of the key features in his troubleshooting help was a newer JAVA polling applet called ‘FindMounts_VFM-XX-XX’  (  The newer script had features that were much more helpful than the previous one which I had been trying to use.

Re: ethernet connection troubles

 

Steve and Remy,


The IP address range 169.254 is reserved by the Internet Task Force for link-local devices that have not been renamed, either by DHCP or another protocol. It isn't a defective IP address.


You might think that however because if your computer has a 169.254 ip address it will not see past the router and connect to the internet. In that situation, it is problematic. In this one however, the CP4 does not need access to the internet. It should be kept as link local. 


Sorry for the confusion, everyone. Remy, I am looking at the information you have sent and will be working with you shortly to try and figure out what is wrong.

Re: ethernet connection troubles

Steven Panish
 

Remy,

Start by looking for the addresses used by the other network components.  Typically a local network will use 192.168.xxx.xxx and the mask will determine the address ranges.  But....my advice is to physically bring someone in who understands network addressing, which is complex.

Subject: Re: [ap-gto] ethernet connection troubles

Thank you very much Steve for your help.

FYI, this address (169.254.1.140) has never posed any problem of Ethernet communication since the reception of this AP1100-AE mount (sn: AP1100-003 acquired in 2013), both with the GTOCP3-AE and the GTOCP4.

But this problem has only occurred since the repair was returned to Astro-Physics ....

But now, not knowing the reasons why this address 169.254.1.141 is not suitable, reading nowhere in the Astro-Physics documentation any information on this subject, I would like to have all information on the type of static IP address allowing me communication via ethernet between a computer and the GTOCP4.

Should I do some engineering studies before acquiring such equipment .....? 

Thanks in advance.

Rémy

Remy,

I am not familiar with your equipment since I have older (ancient!) components.  But the 169.xx.xx.xx addresses are not useable.  They are assigned when there is a networking error.  If you have a friend who knows networking, it would help to bring them in to look at all the components of your network.  In particular, the address for the DHCP server cannot be correct, it would not be a 169. address, and the mask is also not correct.  This stuff is all annoyingly complicated.  I would start by looking at other addresses in your network, particularly the router/switch which is acting as the DHCP server, and seeing what address ranges are being used.  Then I would manually set an address and mask in the correct range for the CP4, and the gateway, which is the CP4's access to the network.  Once you get that working, and have access to the DHCP server, you can try automatic settings.

This kind of issue is very difficult to debug remotely, which is why it would be best to get someone to help on site who knows something about networking.

best,
Steve

Hi Remy,
 
Out of habit, I always use the USB to Serial cable into the RS232 port on the CP4, but I wanted to test the Wi-Fi and Ethernet connections and was having difficulties.   I called George at Astro Physics (probably best to email him these days) and he was able to walk me through the process of setting it up properly in APCC and reaching a successful test.
 
One of the key features in his troubleshooting help was a newer JAVA polling applet called ‘FindMounts_VFM-XX-XX’  (  The newer script had features that were much more helpful than the previous one which I had been trying to use.
 
I would connect with George and he can give you some straightforward guidance on how to set it up with APCC.   I am not a network wizard either and George still managed to walk me through it and get me connected.
 
Cheers,
Greg
 
p.s.  I looked for George’s email which forwarded the polling script, but I can’t seem to find it.  I believe the current version is ‘FindMounts_VFM-01-02’

Re: guiding calibration woes

When calibrating the guider with MaxIm, the scope doesn't move.  I don't get the "L" pattern, and MaxIm  says it hasn't moved, and the pixel coordinate numbers don't change. 
When guiding with MaximDL you first have to establish a connection between Maxim and the mount. That is done by bringing up the Observatory Control window. Then press on Telescope "Connect". If you don't do that, the guider will not function.

Subject: [ap-gto] guiding calibration woes

Mach1GTO, CP3 controller, APCC, MaxIm DL 6.21, QSI 683 camera, Starlight Xpress Superstar guider, Baader Vario-Finder guidescope, TEC140ED main scope.

When calibrating the guider with MaxIm, the scope doesn't move.  I don't get the "L" pattern, and MaxIm  says it hasn't moved, and the pixel coordinate numbers don't change.  I reviewed the functioning of the Superstar guider with Terry Platt of Starlight Xpress, and he's satisfied that the guider is working correctly.  Pushing the N-S-E-W buttons in APCC make the Superstar's LED brighten, as it should, which (according to Terry) means the guider relays are working correctly.  I swapped out the USB cable, with no effect.  I know someone's going to suggest reviewing everything, reseating cables, settings in MaxIm, etc.  I've done all that -- at least I think I have.  Ordinary go-tos (orchestrated by CCD Commander) and plate-solves work correctly.

Is there something that I should look for in APCC or MaxIm or CP3 that might have been inadvertently changed that is causing this problem?  If I need to buy a new guider, I'll do it.  But I want to be sure that's the problem.
