Rotator control 1216L calibration

[Jan (Microbit)]

Received 1216L-5 RCU unit, tested and got the same result as an old unit. A/D reading changes from 734 to 739, voltmeter show stable reading. It's too big error for me. Have video ( not posted on youtube ). Will be returned back.

What is the visible effect of an raw A/D value fluctuation of 5 units? Does the degree value change too?

If you are using a input level that is 0-5.1V then 5 raw A/D units means 25 mV(0.025V), which isn't that much. But if it's not acceptable then we are not able to offer you something better for the time being.

I don't know how many changes or changes degree value, because I did'n viewed it. And it depends by software. I calculated, not exactly, but: 800/360=2.22  One degree have 2.22 A/D units, so my error is about  5 A/D units or 2.25 degrees. It's too big error for me, because I planning mount 1.8m parabolic dish on the 60m tower. Maybe you can configure your RCU unit to accept digital encoder code ?
