Re: Update CP4 troubles

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 the LAN as your first connection choice and use the Serial port as the second backup choice. Both cable need to be connected accordingly but you’ll need to disconnect from APCC to configure the LAN connection. Using the magnify glass with the plus sign should give you the choices you’re looking for but I think that’s well explained in the help file. Give it a good read and see if it doesn’t answer your questions.

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) if say 36 the 169.254.0.36. You enter that IP address number in the top box under Connection using the down arrow to choose either UDP Lan Or TCP Lan and set the backup Port to your serial COM port number that the serial is connecting on below that. You need to be disconnected from APCC to do this. Click on the question mark in the upper right corner of the Connect dialog box for the help file.

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 connect via serial port, USB adapter and wifi but not by ethernet(CP4) to ethernet(pc).

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 (Chrome), I entered the mount’s WiFi address (the one calculated in accordance with the instructions for updating the firmware, see below) as the URL; this brought up the mount’s web page.

2.      On the mount’s web page, under the heading “GTOCP4 Available under Wired Ethernet at:”, I selected “Advanced Ethernet Settings”.  This brought up a page with a list box where you can select a DHCP Mode.  The three available selections are “Client”, “Server” and “Both.”  When I checked it, the setting was “Client”.  I changed it to “Both.”  I then disconnected from the mount, cycled the power to the mount, and tried again to establish a connection, this time via Ethernet.  It worked. I was then able to bring up the mount’s web page and perform the firmware upgrade.

 

Unfortunately, you seem to be unable to complete Step 1 because the utility (which one?) is telling you that the Wifi Station IPv4 address is 0.0.0.0.  Unless you are trying to connect to the mount as an access point in a router-managed network, this is bullshit.  You are presumably trying to establish a connection in a peer-to-peer network, so the address to use is the one that begins 169.254.  The rest of the IPv4 address is calculated in accordance with the following excerpt from the A-P document Field_CP4_Download-browser.pdf:

 

1. Divide the numeric portion of the serial number by 256. Truncate the result so that only the whole

number value remains. Do not round up! This is your first value. Serial numbers less than 256 will use

“0.” Numbers 256 to 511 will use “1.” and so on.

2. Multiply the first value from #1. above by 256, and subtract it from the serial number. The difference is

your second value.

3. EXAMPLE: Serial number = CP4-0635. Numeric portion = 635

a. 635/256 = 2.4804…

b. Truncate to 2. This is the first value. (Remember “remainders” from grade school?

635/256 = 2 with a remainder of 123)

c. 2*256 = 512.

d. 635-512 = 123 This is the second value (the remainder from above)

e. IP = 169.254.2.123

 

If you cannot connect to the mount via WiFi using this information, you will probably want to look into whether there is something wrong with your PC’s WiFi reception (probably not) or with the GTOCP4’s WiFi capability.

 

For more information, see the GTOCP4 Control System Manual, page 15, under the heading “Ethernet and WiFi Best Practice Recommendations,” where the GTOCP4 WiFi/Ethernet connection mode is explained.  Also see pp. 56-57, under “For connections into a local network”, where among other things it says

 

If you have the GTOCP4 configured as a “Server”, meaning you are configured for Peer-to-peer connection, but you are now connecting through your local network, you may need to click the button to open the Advanced Ethernet Settings window to reset the DHCP Mode to either “Client” or “Both.” A power cycle of the GTOCP4 will then be required for the change to take effect – power OFF – wait a few seconds – power ON.

 

It doesn’t mention that the reverse is also true – if DHCP mode is set to “Client”, as in my case, you will have to change it to “Server” or “Both” to make it work in a peer-to-peer situation.  “Client” mode will only work in a multi-point LAN as managed by a router.

 

Hope this helps.

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 drop over the return line can be felt on all metal grounded surfaces in the observatory.

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

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.

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

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

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.

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


Re: Update CP4 troubles

Steve Reilly
 

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.

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 continues to tell me Wifi info but Wifi Station IPv4 is 0.0.0.0.

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

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 initialization failed.  Script error in line 4, position 0"  It looks like the script is trying to use one of the virtual ports created from APCC and not the port created when I plugged the mount into the pc usb port.  Hope this makes sense.

Re: Update CP4 troubles

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 downloaded both parts of the update and installed. That should give you the IP address to use for your CP4. I had to run mine by “Run as Administrator”. That’s the IP address I used to enter in APCC. If I remember correctly I had to click on the magnify glass in the upper right corner of the Connection box to get the information on how to do this. When that’s done you can plug the Ethernet cable in to the CP4 and I plugged the other end into the computer. I have two network connections on my motherboard so I’m using one for network connection and the other for the CP4. I think this is the preferred way to avoid timeouts from heavy network traffic.

Hi

 

I'm trying to update my CP4 from VCP01-10 to current -13.  I can connect to mount using the serial port but can not connect using ethernet port.  I've tried different cables so I think I can rule out cables.  I can connect via wifi and see the ip adress but when I type the address in I can not connect to mount.  I am using driver v5.20.09 on a windows 7 machine(same results on a win 10 machine).  When I run the E-net_Wifi_poll application I get a dialog saying "Please be sure your GPOCP4 is connected via Ethernet.  A local network connection is prefered, but point to point will also work. "  The Find Mount java application tells me No mount on any newwork but when I connect to mount via wifi the application tells me the correct serial # Hostname UDP port or TCP port.  The CP4 is connected to an GTO-1200 mount.

 

Any ideas?

 

Thanks

 

Carl
