Carl, Each one of the boxes in APCC have a question mark in their upper right corners which opens the help file for that section. I think what you’re trying to do is set the CP4 to connect via

Carl, The USB port has a COM # not an IP address. If you are going to use the Ethernet connection you need the IP address that the CP4 has assigned to it being 169.254.0. (the CP4 serial number)

Can you take a photo or two of what you are seeing. Hard to troubleshoot this with so many unknowns...

Hi Bill I see the connection but how do I get the IP address of a USB serial port? I see lights by the connector on my pc, how can I ensure my pc ethernet connection is functioning properly? I can

I had the same problem with the same equipment – GTOCP4 on an AP1200GTO. I resolved it as follows: 1. Established a WiFi connection to the mount. Using my regular Internet browser

If you have a electric _ subpanel _ for your observatory, and the neutral and ground are bonded inside that subpanel, the you might be returning current over your ground wire, which means any voltage

Is the network adapter enabled in Windows? Windows should show you the connection and the associated IP on that interface.

That means the CP4 port is working and communicating with your PC. Rolando

Try turning off the GTOCP4 then starting it again after the computer has booted up. I find I have to do that to successfully connect

Steve I've tried 3 different cables so maybe. When I plug into the ethernet port I see lights flashing next to the port on pc & CP4.

Are you sure the ethernet cable is good? Can you switch it with a known good one for now to test?

Steve I can connect via serial and wifi but not the ethernet port-could it possibly go bad?

If, and this is a big if, I remember correctly, the IP address is always 169.254.0.(serial number of the CP4) for a direct connect to the PC.

Carl, are you using a USB to Serial convertor? If so, any idea what chipset it uses?

Hope this is not a double reply but I'll try again: I ran the utility as Administrator and now it give me Hostname but the Ethernet IPv4 Address is 0.0.0.0 with Wifi mode in Access Point Mode. It

Steve I just run it as Administrator again and it tells me the Host name but the Ethernet IPv4 Address is 0.0.0.0 Wifi mode is Access Point Mode.

Steve- When I plug into the pc from the RS232 port I see a new USB serial port in Device Manager being created. When I run the utility I get the error "No mount on IP Address or Com port, or

Carl, Forget the Ethernet connection for a minute and concentrate on upgrading the CP4 using the serial connection (top RS232 port). Then run the E-net Wi-Fi Poll software that installed when you

It's never failed me except one time when I used a bad cable. Rolando

Sorry, plugging into the pc at one end, the mount on the other end.
