Ardruino driver and home made dome

dorin.ivan — Sun, 14 Jun 2026 15:40:27 +0000

I have the following configuration: home made dome with a diameter of 3.02m, Arduino driver from Scopdome, Ioptron cem 120 mount, Askar 185 telescope... from the zero position of the dome it moves in any direction with an accuracy of + or - 3 minutes... the problem occurs when synchronizing with the telescope: if I enter the measured geometric data and do not enter the GEM value = 0 (the measured one is 361mm) the dome moves from position 0 around 22° also even if in position 0 it is centered on the shutter (width is 700mmm) the telescope stops at the edge of the shutter with small differences depending on the x and y values entered... it is probably a geometry problem but I can't figure out where I am wrong. Does anyone have an idea that could help me?

Arduino drive configuration SideOfPier

I want to ask about driver configuration dialog, page "Telescope" - there is group box with lebel SideOfPier choices, this one:

119

Option ""Invers SideofPier" is clear, but it is possible select multiple of first 3 options. What means, if I select/check more than 1 option e.g. "Use from scope" and "Calculate" together. What is the logic, is defined some priority or what happens, where will be SideOfPier taken from?

Thank you

How to set IP addres on scopedome arduino card

admin — Fri, 12 Dec 2025 10:47:09 +0000

- Connect the card to your computer via a USB connection.
- Open ScopeDome driver and conect it to the card via USB.
- Connect your computer and the card to the same IP network hub.
- Launch Command Prompt and enter the command “ipconfig”.
- Read the "IPV4 Address" value (in this example: 192.168.2.198).
- This means that your computer is operating on the 192.168.2.x network.
- Select a free IP address on your network, e.g., 192.168.2.120.
- Enter this address in the “IP address” field in the card's Config window and press the “Set IP” button.
- Press "Save Settings" button
- Restart card power
- Set "Connect by" value to "Ethernet"
- Press "Save Settings" button
- Close config window and restart the driver.

P.S.
Remember that the card's IP address can only be changed when it is connected to a computer via a USB port.

A short instructional video showing how to start using the MapPoint procedure in a dome. Good luck!
