Hi,

Some great and practical advice!

I am helping a friend set up his recentlypurchased ASIAir Plus and G11 w Gemini2 (which I sold him). What is the proper sequence to startup and get connected and ready to do a Go To. Assume the mount has been levelled and is polar aligned. I always liked Cold Start w CWD:

--- Everything powered off:

--- ASIair physically connected via printer cable to Gemini2 control box.

--- Mount is in CWD position.?

--- ASIair App (on Galaxy S9 turned off)

?

If the ASIair will not recognize the USB connection to the mount, then what should I try? Change the power up order?

When I had the mount, I used Serial to USB with FTDI, and it connected to my laptop nicely. I think there was a FTDI driver. Is this a back up option to try?

?

Any other option, ie LAN? Many thanks for your advice!

Roger

This is the control box:

Hi Roger,

?

I have always used the Ethernet ports to talk to the Gemini 2 for imaging and planetarium app use so I just found a way to keep using Ethernet connections when I switched to the ASIAIR years ago pre-COVID.??

This is not hard to do but you do need to configure the Gemini 2 and ASIAIR specifically to do this. But it is well worth it as you will be able to use GFU and have network access to the Gemini 2 mSD card file system. There are also a lot of control through the web UI which gives you a acess to everything in the Gemini 2 which you don't even know about without it.?

?

Using the Ethernet port also frees up one USB port on the ASIAIR which on a full house system are always going to be in short supply especially with the new CAA (camera angle adjuster) coming out shortly.? If like most folks your friend will be or is planning to run a full ZWO imaging system with ASIAIR , EAF, EFW, ASI autoguider and ASI cooled imaging camera? ?means there will not be enough ports to plug everything into the ASIAIR if you want to use the CAA and an external USB SSD/Flash drive. Unless of course there is a USB hub built into the new CAA.?

?

So looking forward if you can set your friend's Gemini 2 to use Ethernet for command and control this is a big help and supposedly allows for better mount performance.? This is what the people who wrote the software have said all along anyway. I can't confirm it, as long as I have had a Gemini 2 I have used the G2 Ethernet port for communication.??

The way I do it is simple. I use a small high-end travel router and plug the Gemini 2 and ASIAIR into the switch ports of the router.? The best small routers with the newish WiFi6? 803.11AX standard AND at least 2 or 3 Ethernet ports with full 1Gbs Ethernet are the GL.iNet travel routers. I am using the Slate-AX model as it has the best specs and includes a third Ethernet port. It is very a very fast WiFi router if you are near the router, faster than wired Ethernet. If you have a phone that is less than 5 years old you probably have WiFi6 and can take advantage of this much faster WiFi standard.

?

These days I am no longer waiting at all any more for the data to move between the ASIAIR and the phone with this setup, focusing, preview downloads from the ASI2600MC Pro take longer to process on the ASIAIR than to download. But it wasn't always the case, in fact it was SLOW.? But at least the WiFi connection was not failing every 2 minutes.?

?

I have seen the screen responsiveness improve as download speeds increased.? I kept upgrading as newer WiFi technology came out for nano and travel routers and I moved from the router I hung off the Gemini 2 for WiFi access and bridge routing to my home mesh LAN to needing to overcome the terrible ASIAIR WiFi which requires additional 1Gbs Ethernet ports at the mount router.? At the time there was no such thing as a multi port travel router so I used a 4-port mini 1G/100/10 switch to add the required ports. I went from the?

150Mbs 802.11n TP Link nano router>

300Mbs 802.11n TP Link nano router >

433Mbs 802.11ac TP Link travel router >

433Mbs 802.11ac Slate with 3X 1Gbs ports>

867Mbs 802.11ac Beryl with 3X 1Gps ports>

?

The speed improvement I have seen is very significant. But you really have to have a newer phone with Wi-Fi 6 to take advantage of the technology. You can verify what Wi-Fi your phone has in the settings pages.?

?

Let me know if you need any more advice or screen shots for configuration of the Gemini 2, ASIAIR and Slate-AX router.?
