Well, after a power failure I go out to use my scope and the IP address is changed. Looking through my router, there is no indication of it.
So, read the manual and I have to download a JAVA applet.
It needs a user name and password!!!
Any alternatives or do I have to wait until Monday for the shop to open?
First time in my life I have seen a network interface with no possibility to do anything except guess.

Tom,
Sometimes router have a hard time showing new Ethernet clients. A utility that can help in this task is Advanced IP Scanner. It will give all the clients on the network served by the router and if the CP4 is on it, it will find it.
Is using a USB cable out of the question?
Cheers,
Luca

1) You could use an IP scanner utility (such ashttps://www.advanced-ip-scanner.com/) and scan the entire subnet (use the 3 first bytes of your computer's IP address + .0/24. e.g. if your IP is 192.168.0.16, type-in 192.168.0.0/24 in the search bar of the scanner app). If your CP4 actually has an IP address in the same subnet as your computer, it should find and list it.
2) Use the following math (from the CP4 manual) to calculate the default IP address and connect directly to your CP4 through an ethernet cable. Thenchange the IP address of your network card to 169.254.0.1 with subnet mask 255.255.0.0:

3) If you still can't find it, use the IP scanner app again to scan the entire 169.254.0.0/16 subnet. That could take a couple of minutes as it needs to go through the 65,000+ possible adresses, but should find it in the end.
Hope this helps...

If you have not tried it yet I would reboot the router, wait a couple of minutes, then reboot the CP4. The DHCP function in routers sometime puke out and will stop handing out IP addresses which the CP4 should be requesting on each power up.

Thank you guys so much! The scanner worked. I had been entering the IP address manually and gave up at 192.168.1.155...it was 157 lol...
This is nuts though. The tool should be in the APPC or astro-physics folder. One should not have to go through so many hoops to get this.
Anyways, you guys saved my weekend.
I'm going to write a utility to do this myself and share it here if I can.
Thanks again!!!
#75921

Great to hear you got the new address. If you can log into your router, you can lock the CP4 to that address via a 'reserve' function. Basically the router will only give that IP address to the CP4 mac address.
Pete
#75922

Will do.

I also got a new router in the last few days, and this router does not show the IP address of the mount until it is connected. That is strange since my old one did.
I never had the issue before.
Can one put a static IP into the CP4? I see no options to do so or is it in the web interface?

Hi
Yes I know. However, you require a user name and password to get access to it.
Hence I was wondering if I needed to wait until Monday to get it.
Not very user friendly. If a person is at a remote site they could have wasted time going there. I can understand that perhaps there is some considerations about intellectual property, but in this case, an IP scanner tool does the same thing. Not to mention that if it is at a remote site, you don't necessarily have access to the serial number.
IMO, It should just install with APPC.
Best regards, Tom

APCC has a function to find your CP4 if it is on your LAN and assigned an IP address by your router, which looks like the case from what you said above.

Tom,

There are several tools that can be accessed from our website. Click on the Support tab and then Technical Support for Current Products.

Scroll down to GTOCP4 and GTOCP5 Control Boxes and take your pick of several options.

As Ray mentioned, APCC can also provide the information that you need.

Our tech team is revising the recommendations for accessing your CP4 or CP5. Since IP addresses can change, it might be better to set up your own user name and password.

We recommend that you write all of your serial numbers in your manual for future reference as well as other useful information.

Clear Skies,

Hi
Ray,
Yes I found that option except it did not work at all. No mounts show up.
In fact my router does not even show that the CP4 is on line or off line. It does however assign an IP address. The router is as state of the art as can be, a WiFi 6 router. I am using a cabled connection from the CP4, not WiFi.
There is one other device on my Net that does not show up. An aquarium controller.
#75938

Marj,
You need a user ID and password to download the mount finder. Really not needed.

#75939

Hi Tom,
APCC broadcasts a message to your entire LAN so some reasons why the CP4 would not have responded are:
1. The CP4 wasn't powered on.
2. The CP4 or computer were not connected to the same LAN subnet.
3. The CP4 was configured incorrectly for the LAN (e.g. a static IP inconsistent with the router's subnet).
4. The router hadn't provided an IP address to the CP4 via DHCP.
5. The router blocked the broadcasts.
In cases where you can't figure out the problem, it might be worthwhile to have an alternate way to connect (i.e., serial or USB cable).

The first 4 are not the case. DHCP did assign an IP address. The Fifth, broadcasts, might be the case. It's a new router but I would think it would enable broadcasts by default.

Assuming you can now connect APCC via the network to your CP4, you can narrow down the reason for the original problem by using the Find CP4/5 feature in APCC.
To use the feature, you will have to disconnect from the mount first, then click the button with the magnifying glass.
If APCC finds your CP4, that means one of the first four items likely applied.
If APCC does not find your CP4, you should check your router's settings to see if it is blocking broadcasts.
