Hi, I need some help.
For the past few days, I can no longer connect the GTOCP4 by Ethernet (Windows 10 OS, APV2 v5.30.09, APCC Pro v1.8.0.5). Several tests carried out with different cables without results, the connection by Ping (cmd: ping address) allowed me to check the good reception.
Do you have any suggestions to correct this situation, thank you.

You may not be typing in the entire address. I normally use the "Find Mount" app. Comes up right away.

Thanks Roland, but it doesn't work either.

And strangely enough, it only works when I select an automatic address (network and sharing, IPv4, DHCP) and at this time the address of the mount is well identified (by "Set up telescope" and “APCC") .... Surprising! 

But when I manually indicate this address (IPv4) of the mount, the mount is never recognized ... (?!) ...

Do you have any idea what might be going on?

Thank you.

Ben, Roland,

how do you "see" that the computer’s IP address is the same as that of GTOCP4?

Do you confirm that the “GTOCP4 Ethernet - Wifi Poll” link allows us to indicate and / or modify the address of the GTOCP4, page “GTOCP4 Wired Ethernet Properties” (as this screen shot), 

<E1-Chgt adress.png>

and page “Wifi Interface Available on this GTOCP4” to enable / disable the Wifi connection and to connect / disconnect it  (as this 2nd screen shot)  ?

<Wifi enabled.JPG>

Would you tell me how to choose a manual IPv4 address with “GTOCP4 Ethernet - Wifi Poll” link, please.

Thank you very much for your help.

I can't quite make out the text in the screen cap on your response, sorry.

On a previous email, you said:

this is the IP registered using the link “GTOCP4 Ethernet - Wifi Poll" :

followed by a blue box ("Advanced Ethernet Settings") that says "Default IP Address: 169.254.1.141".  If I'm understanding correctly, that is the IP address of your CP4.

In the same email, there is what I *think* is a picture of your Windows network settings, where you have statically set your IP ("Utiliser l'addresse IP suivante") to be the same IP address of your CP4 (169.254.1.141).

You'll want the CP4 and the Windows computer to have different IP addresses or else they'll be unable to communicate.  If you're statically setting the IP of your computer, use a different IP from the CP4.

Mr. Gralak would be the authority here.

I haven't used CP4 (don't have one) , tho I have noted in passing the number of issues with networking (which isn't really surprising giving tcp/ip networking in general has lots of variables even with "standard" equipment).

That said, these 169.254.x.x address look suspicious to me.   (Tho the screenshots of the PC side look a bit confusing; I can't tell if both the PC and the mount have the same self-assigned address -- it looks like they do.)  169.254.x.x is a reserved block for "self assignment when dhcp fails".   (happens all the time on windows when the wifi is problematic.)

I am totally guessing here on why ping works:   If the PC and the mount have the same self-assigned 169 address (seems plausible to me), then the PC "ping" command to that address is actually pinging the PC, not the mount.

After reading the CP4 manual, it seems the CP4 has a DHCP server for the "direct ethernet connection" known as "peer to peer" mode.  

I saw screenshots with "dhcp: client", which doesnt seem correct if "peer to peer" is the desired connection mode.

Here's the part from the manual:

• Set the DHCP mode to SERVER ONLY if you will be connecting directly, peer-to-peer with a computer. Change these on the “Advanced Ethernet Settings” page of the GTOCP4 internal web page set.

• If you wish to set the DHCP mode to BOTH, understand that the GTOCP4 will start out in "client" mode, and then switch to "server" mode if it is not assigned an IP address after a timeout period. Per IEEE standards, the switch to server mode will take place after more than 30 seconds, so you may need to be patient if waiting to use the GTOCP4 as a peer-to-peer device when set to "both.

Maybe the PC needs to be unplugged from ethernet for like 30 seconds after restarting the CP4 so that the CP4 can a) go into DHCP server mode, and then b) allow the PC to get a DHCP assigned address from the mount.

I don't know if there is some convention used with the CP4 for "wired without router" connection (crossover cable?) such that self-assigned addresses (169.254.x.x) are used, but in this case if I wanted to "hardwire" the mount and the computer (no wifi) I would :

- include a router in the mix, 

- wire the mount and the computer to the router over ethernet, 

- turn off wifi on both the computer and the mount.   

DHCP ~should~ work, (according to the manual the CP4 comes up as a client initially).  

As an alternative, the router should have a setting for static-ip range.   (Either in the 192.168.x.x , 172.16.x.x, or 10.0.x.x blocks). 

- Enable this feature on the router (usually enabled by default)

- pick two static IPs (different values) within the range for the mount and the PC.   

- In this case the PC and the Mount should have DHCP turned off.  

- Again , wifi turned off on both sides.

Finally, if you don't have a router, I believe you can use static IP addresses in the above mentioned blocks; and I presume the "DHCP Server" mode on the CP4.

Maybe the intent is to use the self-assigned addresses, but they will need to be different on the mount and PC.   And imo using the self-assigned range just confuses things.

Hope this helps, and doesnt confuse you further.

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’

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

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.
