Re: Can't Connect To CP4
kendunc@...
Thanks Ray and all. I will look into the APIPA thing when I get a chance. It seems that my laptop is connecting OK with a direct Ethernet connection, going directly from it to the CP4.
In another post Pete had asked if the mount is used. All equipment is new, I am the first owner. Ken

Hello,
Yes I downloaded the USB driver from AP. Thanks for the tip. Ken

Re: Can't Connect To CP4
I see that you got it working, but for the benefit of others that might have the same problem:
Connecting directly to a device with an Ethernet cable usually requires that No, I have not seen that referenced anywhere. How do I do that?It depends on whether your computer/laptop sees a DHCP server or not (e.g., a home WiFi router). If the computer sees a DHCP server, and the computer is set up to use DHCP, the LAN port may get set to a subnet different than 169.254.x.x, so you probably won't be able to detect the CP4. Some choices: 1. You can either turn off the WiFi router and reboot your computer. This should allow the LAN port to default to APIPA addressing. If it doesn't, you can change the settings manually. 2. You can manually change the computer LAN Port's TCP/IP V4 settings to use IP subnet 169.254.0.0, with subnet mask 255.255.0.0 (or Subnet Prefix Length = 16). https://support.microsoft.com/en-us/windows/change-tcp-ip-settings-bd0a07af-15f5-cd6a-363f-ca2b6f391ace Remember to save and restore your settings afterward! 3. If you have a DHCP server, instead of connecting your computer directly to the CP4, you could connect the CP4 to your LAN via Ethernet cable. Note that WiFi won't work by default as it will not have been configured yet. After connecting the Ethernet cable, power cycling the CP4 should allow the CP4 to acquire an IP address on your LAN via DHCP. Your computer, which will also on the LAN, should then be able to detect/connect to the CP4 via Ethernet. -Ray Gralak Author of PEMPro Author of APCC (Astro-Physics Command Center): https://www.astro-physics.com/apcc-pro Author of Astro-Physics V2 ASCOM Driver: https://www.siriusimaging.com/apdriver -----Original Message-----

Re: Can't Connect To CP4
Roland Christen
For my observatory setups I use the USB connection for direct mount control. No need for Ethernet for that basic function. The only reason I have Ethernet connections to the mounts thru-out the factory is for making the mounts accessible to our employees that are working remotely from their homes. But for normal control of the mount the USB connection is fine.

How old is the mount / CP4? If you got it used, can you reach out to the previous owner and see if they experience any issues like you? Glad to hear it is connecting now.

Before you try the USB connection, download the driver for it from the AP site. Jeff

Re: Can't Connect To CP4

Well for whatever reason, after trying for two days, not changing anything, it now sees the CP4 and connects to the mount in APCC Pro.
Thanks all for the help. I am sure I will have other issues that I will need help on. Ken

Re: Can't Connect To CP4
I don't know if it's better/same, but USB is definitely easier for us

Hello,
No, I thought that the easiest and less prone to other issues would be to use a direct Ethernet connection. I ahv e tried different short cables and my desktop and laptop.

Sometimes you have to hit the refresh button a few times to get it to locate it.
If that is still not working, it is possible the cable is faulty, or the network interface is older and wont support a connection without the use of a crossover cable. That I would doubt, but something to consider.

Yes, I used that and it found nothing. I felt a better way with less potential issues would be using a browser without adding other software into the mix. Nothing I have tried shows the CP4. Thanks, Ken

Re: Can't Connect To CP4

In APCC you can have the software search the machine to locate the correct interface and IP address. Have you used that utility? The + sign magnifier glass is what I am talking about:

Re: Can't Connect To CP4

I doubt that it is the CP4 that's the problem. I have alerted our software guys and they should be able to help you out.
I also sometimes cannot connect my laptop to my scope via Ethernet. In some cases cycling power on the CP4 allows the laptop to "find" the new connection and then i can connect. It seems the software in my laptop gives up after a couple of tries and won't find any Ethernet connections until i do the power cycle.

I am in the process of setting up a new 1100. I have tried to connect to the CP4 with APCC pro with no luck. This is with a direct Ethernet connection between computer and CP4. I have tried connecting with Ethernet via web browser and can't connect to the CP4. I used the math method of appendix C of the CP4 manual to determine the address for the CP4. I also used a AP provided web site where you enter the serial # and it gives you the address for the box. Both methods give the same address. I have used multiple Ethernet cables. All equipment is new. I am now thinking that possibly the new CP4 is defective. Hopefully someone can help me out. Thanks, Kenneth Duncan -- Roland Christen Astro-Physics
