Gemini 2 Unable to Connect Telescope via Direct Ethernet
Hello Group:
Based on Brians Connecting the Losmandy Gemini via Direct Ethernet, all IP address settings have been incorporated into the HC, changing ethernet adapter options, telescope configuration with the Gemini Web Server, etc.?
After completing all settings, the Gemini Telescope connection worked the first time, but no connection can be made there after.? ?
Would appreciate assistance in resolving this issue. Here's some screen shots. Additional supporting photos can be added if needed.? Thanks, Ron M |
Hi Ron can you send pics of your computer ip settings as well? On Tue, Jun 23, 2020 at 12:41 PM Motorfix via <rm2642=[email protected]> wrote:

How recent is your laptop? gemini is powered on, right? (i have to check :) ) I have to look at this some more but two things come to mind to check: 1. can you?try a different ethernet cable? 2. for the computer settings, can you try using the IP address of the Gemini for the default gateway On Tue, Jun 23, 2020 at 1:36 PM Motorfix via <rm2642=[email protected]> wrote: can you send pics of your computer ip settings as well?Thanks Brian: --

Where is the IP address info for the gemini hand controller? can you snap pics of that On Tue, Jun 23, 2020 at 12:41 PM Motorfix via <rm2642=[email protected]> wrote:

Brian:?
Thanks for the quick reply. I will swap out the old cable for a new, 20'? cat 6 cable and take photos of the hand controller ip addresses. The Losmandy/GPS receiver is connected to the Gemini 2 Serial/GPS port and works great. The laptop is a new Dell (W10). The Gemini Web Server Software version of the Hand Controller did not work.? The desktop PC (W10) is giving me the "Gemini will not connect message". So actually, telescope control is a problem with both computers. More detail and photos to follow. Thanks much, Ron M |
Hi Ron >>> The Gemini Web Server Software version of the Hand Controller did not work.? it won't work until you connect the computer please do send pics of the hand controller. i suspect that setup is where there may be an issue On Tue, Jun 23, 2020 at 7:44 PM Motorfix via <rm2642=[email protected]> wrote: Brian:? --

I think I'm giving up on this Ethernet stuff.
1. My mount computer does not have Ethernet capabilities. No port, and my USB/Ethernet adapter doesn't seem to let the computer even see the Gemini 2. 2. My USB, Powered HUB, and a single USB cable works flawlessly, for everything. And the Gemini 2 Ethernet does not readily allow for my cameras and focuser to be added into the Ethernet, even if it did magically start working. 3. My mount computer readily WiFi's to my Main Computer, where I can use Tight Vnc to show the Laptops entire display and all functions. 4. I also have a wireless router in our RV now. So I believe I could readily inter connect there, wirelessly, with an additional tablet or Laptop (work station) in the RV for field use. Quite possibly with a Smart TV and a wireless keyboard. I found the Ethernet port vital for updating or reinstalling the firmware for the Gemini. So it has merit for that. But until and unless the Ethernet port can be a truly single port connection, handling everything between the mount, and the indoor computer, it is only valuable to me as a maintenance port. So for that reason, I'm out. (to quote Shark Tank). -- SonnyE (I suggest viewed in full screen) |

As shown below, the HC and Computer connections are made and are not removed during or after set up: HC with coil cord - HC Port Yellow Ethernet cable - Gemini 2 Ethernet Port to Computer Ethernet Port Serial/GPS cable to GPS receiver Photos below for reference including the Computer Network Connections panel. I will replace the Ethernet cable and retest tomorrow. Thanks? Ron M ?? |

Brian:Hi Ron, The settings look OK to me, maybe Brian will spot something I didn't. Can you try plugging Gemini and your PC into a network switch or a (micro) router, instead of directly into each other? While gigabit ports usually will work with a normal ethernet, straight-through cable, this type of a connection between two devices normally requires a crossover cable. A switch or router will fix that. Alternatively, if you have an ethernet cross-over cable, you might want to try that. Regards, ? ? -Paul |
I have never managed to get a direct PC or laptop connection to work on any computer regardless of age or Ethernet port type. All of my computers and laptops are 10/100/1000 ports, have they even made any 10/100 port laptops in the last 10 years??
Stick a modular crossover adapter on the cable, a network switch or router in between and no problems.? -- Chip Louie - Chief Daydreamer Imagination Hardware |

This is strange. Direct ethernet works for me without any issue. It is actually more reliable than connecting through a router. I now have it working with two different computers - my laptop which does not have an ethernet port (and so I use an enternet to USB adapter) and a box computer that does have an ethernet port. The only time I get the error reported by Motorfix is if I have a bad cable or loose connection. On the flip side, I've never been able to get USB to work so far.

If one uses a straight through cable (normal ethernet type) to connect two devices, pin 1 on one device will be connected to pin 1 on the other. Pin 2 to pin 2 on the other. Pin 3 to pin 3, etc. Except, pin 1 is Transmit on both, pin 3 is Receive on both. In effect, if transmitting on pin 1, the other side is not going to listen on that line, and if receiving on pin 3, the other side will not be transmitting there. This is why you'd normally need a crossover cable. It will connect transmit on one side to receive on the other, as it should be. Or, most modern 1GB+ ethernet ports have auto-detection built-in to check if a crossover is required, and will then switch the meaning of each of the pins to connect two devices properly.?

PS.Astronut The Ethernet?Device?names are different between the Dell laptop and Dell desktop device manager?listing and network adapter interface as illustrated below. The Ethernet?TAP - Windows Adapter V9?as shown for the Desk Top computer is for VPN network connections to the internet. As far as I know, this is the wrong application to use for Direct Gemini 2 Ethernet Connection and cannot be changed. Please correct me if I'm wrong. All the Gemini 2 settings used for the Dell laptop work as instructed by Brian's Direct Ethernet Video. The Gemini 2 built in software version of the Hand Controller works fine. New Cat6 cables installed. Thanks to all. Ron M ? |
Hi Ron,
When I got a new Ethernet to USB adapter for my new Surface Book, I got similar results (a device did show up in the device manager without the warning bang symbol, but the connection did not work properly until I downloaded the ethernet mfgr's specific driver. Windows led me to believe it should have worked with it's built in driver, but it didn't. After loading the latest mfgr driver, the NIC adapter worked perfectly as expected. I'm a little thick, and apologize if you already answered it from your last post, but I gather that the direct ethernet browser Gemini interface (192.168.1.110) IS working, but... Is the Gemini.NET interface working as well now ? (Also, just curious, did you end up specifing the primary DNS server in your PC NIC properties?) Lastly, when multiple network interfaces exist on a PC (Wired, WIFI, etc) *sometimes* the settings may conflict with each other. To get a overall view of your network settings on the pc, You can launch a command prompt, <Windows Key>+ <R>, type in CMD, then from within the command prompt, type IPCONFIG/ALL and this will give you a summary of your PC's networking configuration. You can even save a text file of this on the desktop by typing IPCONFIG/ALL >%userprofile%\desktop\ipcfginfo.txt (the actual filename part ipcfginfo.txt doesn't matter and can be any valid filename) Again, sorry to bother if everything is already working for you, just wanted to be sure all is really good in Gemini-2 land... Thanks, Astronut Tim |

A copy of my IPCONFIG.txt file for the Dell Laptop is attached for reference (I think it's attached! ) Thanks for the help. Ron M |
Hi ROn >>Yes, the direct ethernet browser Gemini interface (192.168.1.110) works perfectly with the Dell Laptop. if that's the case, then it's really should be just a setting in your software that has a bad setting.

Hi Ron,?
Glad to hear the laptop is working. On the desktop front, I am no security or even networking expert, but I have not found any "TAP" interface on any of my PC's, and I have quite a few. After looking at your ipconfig file, you DO have IP6 enabled on several network interfaces. Unless you actually are using IP6, it may be a good idea to disable it. By default, I disable IP6 on all of my pc's as I simply don't need it, and have not missed it. I also usually disable everything in each of network properties dialogs EXCEPT for: Client for Windows... File and Printer Sharing... QoS Packet Scheduler... IP4... Everything else, I disable, and my networking seems to work fine. (I DO NOT use DHCP on my networks, and because of that, have assigned static IP's to all my network devices) I have found in the end, it has made my networking easier to manage and troubleshoot, (Devices stay (at IP addresses) where I put them, rather than where a router wants to fit them in), Yes, I know there are methods to set up DHCP reservations and such, but for me, I chose the static IP assignment route. Concerning TAP interfaces, I found: and if it were me, and I had nothing critical on my desktop, I would probably pursue the link I included above, but again I am no security or networking expert. If you are using any remote connect, VPN, or similar software mentioned in the link... Also if you have virtual machine hypervisor installed on your PC (in Programs 'Features') and are not needing them maybe uninstall that. As well as if you have IIS installed and are not using that, maybe uninstall that as well. Many computers nowdays, still come with bloatware, and perhaps this (the TAP interfaces) are a byproduct of that. Please remember that I am going out on a limb on this one and am no expert on these matters, but perhaps just adding a new NIC adapter may be a band-aid, instead of a cure. There ARE other more advanced troubleshooting tools available (free) to aid in resolving this situation, such as WireShark for NIC troubleshooting, and ProcessExplorer, etc (systools) to exactly identify what is going on, but they do require more effort than simply trying to get rid of the undesirable interfaces as described in the link. In a worst case, possibly doing a windows repair (reinstall), MAY have a positive result, but that may be like using an shotgun to swat a fly. Chip and Tim (and others), If you guys have experienced this, or have better advice, please chime in :) Good Luck Astronut Tim |
