Rotator control 1216L calibration

[oh5bq]

I have Yeasu G-800S rotator with 1216H Webswitch and 1216L Rotator control (analogue). How can I make calibration to whole scale 450 grads?
(my full CCW position is 120 grads and full CW is 210 grads)

The way it is designed 360 degrees is the highest usable value, at least when it comes to the user interface. I guess it would be possible to use it with a 450 degrees analogue rotator by setting up 0=0 and 360=450 degrees, but then the user interface would not show the correct degrees.

Ok.
Now the interface needle stops after overriding and it is not good. I hope you put this feature in wishlist of 1216H/L development.

I will add it to the feature request list, though I can not promise it will be added.

Hello,
can't find any information about RCU1216L-5 improvements ( http://www.webswitch.se/wp/?page_id=491 ). Is it bigger resolution, how about A/D reading error. Older version has selectable 10bits rezolution, new version has fixed 10bits rezolution. Where is the difference ?

The main difference is that the -5 version has 10 bits A/D accuracy. The older versions had a maximum accuracy of  8 bits(even though it was possible to select a higher resolution, but that might cause the conversion results to include random noise.)

The -5 version uses this CPU:

Hello,
one more question. Does this controller has A/D reading error like older versions ? Does it stable reading ? Is it possible to tune parabolic antenna, is it really 10bits 360/1024=0.35 degrees precision ?   I have 1216L-3 series, is it really 5 series  controller better ? If I buy this controller and the result will be the same ( big reading A/D error ), is it possible return ?  (Maybe possible exchange with my 1216L-3 series RCU, because it is not usable unit, only spent money ? )

 Microchip:  10-bit resolution, 12 channels ( like GPS receiver )
Why not 16-bit, 1 channel More resolution, less reading error. Maybe it is possible to use digital encoder Why so simple things performed so hard

The 1216L is primaray designed for rotating HF antennas where a resolution of 1 degree is more than enough. The equipment around like analog rotor controllers, potentiometers with long cabels etc. introduce so many errors so higher resolution A/D is waste of money.

Is it mean, that newer version of RCU 1216L-5 with real 10bits A/D converter has the same rotation error of few degrees Buying of new version RCU 1216L-5 is "waste of money" ? Because older version 1216L-3 is real waste of money. I asking you 10sec. video about how works this new unit ( you can post it on youtube, show difference between the old and new system ). What is the A/D reading error: ±1 or ±2 or more   Because I need a rotator controller, please answer to that questions, I can buy your RCU or must looking for another controller ?

My first film published on youtube

I don't know how it will help you

this is the rotator to my 36 m tower with 9 yagis pointing to C21EU

http://qrz.com/db/sm2oan

the -3 has the same stability if the capacitor mod is done and you use the full 15V span

the -5 version is better if the input voltage is lower as the input range is selectable and the resolution of the A/D is better

Hello,
in this page we can see how changes ( or stable ) "Last A/D: " reading. Please, 10 sec. video: 2 sec. rotating and how changes A/D reading, and 8 sec. is it stable reading. If all OK., I buy this unit !!! I want to see working, not freezing PC monitor ( sorry, but it is important for me, because I have another one RCU unit ).

As long as the  live update LED is green the page is updated with A/D readings

the direct read A/D valeu is 616 all the time, no variation if it's calm, if it's windy it will vary a bit because the tower moves

About 1000 kg tower and antenna will not stop direct it will shake a while before it's stable.

If the product do not match your needs, please buy something better.

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.
