Hi Joerg,
For values that high, you must use the Terminal Window in ServoConfig.
All commands must be in CAPS.
Open Servo Config and select the correct COM port.
Click Terminal Window
A window should pop up. Make sure you are communicating with the controller by pressing ENTER on the keyboard. A string should appear something like this, X# Y# XZ# YZ# XC# YC# V# T# X[AM] T[AM]
Here are the commands for both motor and mount encoder ticks. Use has needed.
Do not use commas or parentheses when typing number of ticks.
For Az/RA motor encoder ticks type: XXV(Ticks) and press ENTER
Type XXV and press ENTER, you should see XXV(Ticks)
For Alt/Dec motor encoder ticks type: XXU(Ticks) and press ENTER
Type XXU and press ENTER, you should see XXU(Ticks)
For Az/RA mount encoder type: XXZ(Ticks) and press ENTER
Type XXZ and press ENTER, you should see XXZ(Ticks)
For Alt/Dec mount encoder type: XXT(Ticks) and press ENTER
Type XXT and press ENTER, you should see XXT(Ticks)
To save configuration, type XW and press ENTER.
Sometimes, SiTech don't like the input and you will have to ignore the warning.
Best,
Russell R.
