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.
Always include type of hard/software and version when asking for support.

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 ?
