Hi to AllI am looking for information for the opencockpits group about the compatible encoders for the IOCards. I wanted the readers of this forum that have badges IOCards with encoders to put here the models that are using, and how the encoders is connected to the master card, directly to the card or through the encoder 2 card. Thank you for your help.Jose

Opencockpits have a forum in english for hardwarehttp://www.opencockpits.com/modules.php?name=ForumsThere's some topics about type of encoders etc ...Take a lookBOB

Hi,You can connect grey type rotary encoders directly to two consecutive inputs of a master card. The encoders I use are from Peter Cos (FlightDeck Solutions). Go to my web site, IOCards page, section on rotary encoders.Nicowww.nicokaan.nl

Hi Nico: I know about the the technical data of encoders. I am of Opencockpits Team. I need the exact model that the users connect to the cards. Thanks for your answer, and congratilation for your web site. It see very good.Jose

To backup Nico's comments. I bought the same rotarys from FDS on the advice from Nico's website, and had no problems!To help out Nico, the FDS part numbers are:REWP & RENPHope this helps!Regards,Brad Heller.

Those are roughly $5.50 a piece, discounting a bit if you buy many of course. Not entirely unreasonable from FDS either, $6.50 there which makes sense to take them from Peter if you are buying panels as well, saving the $1 per switch in shipping costs anyway..Another VERY interesting one by the way, is Bourns ESD0D-S00-GC0006 - available from www.mouser.com - it is having similar output code, which I assume would work wiht iocards directly, but the cool part is, it has a HOLLOW shaft - meaning it might be possible to glue in a 4mm alu/brass pipe and use it combined with the above with-switch regular encoder to make a nice dual concentric thing - those are a LOT smaller than the 12-position switches.. thinking about the GNS530 here.. :)But PLEASE - someone who knows more about iocards, can they check the datasheets if those would indeed work?Bourns also has ECW1J-B24-BC0006 which should be similar..?//Tuomas

YES!, if you had taken the time to read my site carefully you would have seen this line:"Therefore I ordered this type of rotary encoder (RENP, from CTS corporation type 288) at Flight Deck Solutions (Peter Cos)"I will put a box around it and start my section on rotary encoders like this because it seems difficult to grab the information:2-BIT GRAY TYPE ROTARY ENCODERS WITH 1/4 CYCLE PER DETENT can be connected directly to two consecutive inputs of the Mastercard of IOCards.(Note: how many detents per revolution does not matter, that's a matter of taste)>But PLEASE - someone who knows more about iocards, can they>check the datasheets if those would indeed work?I have had a look at the data-sheet:The 1/4 cycle per detent 2-bit gray code will work fine with IOCards.Nicowww.nicokaan.nl

The Openecockpits team don

Jose,IMHO: The number of detents per revolution has no influence on the working of IOCards. The only thing that is important is that with each detent only 1 bit changes (so called 1/4 cycle per detent).Imagine, how could IOcards tell the difference between a 16 detents and a 24 detents per revolution rotary? That's not possible! It's something in the physical world not the electrical ...Best Regards, Nicowww.nicokaan.nl

It just rotates faster or slower, I guess you can divide the value in iocards software anyway?

I have some small encoders without detents, that have the similar output though, it works okay if turned slowly, but gets a bit messed up if rotated fast. I guess it depends on the actual component and its quality of the signal to get a good response from iocards? Do your encoders have this problem?//Tuomas

Hi Tuomas,>Yeah. It just rotates faster or slower, I guess you can divide>the value in iocards software anyway? (I havent really>configured my iocards much yet, planning still and building>panels)Sort of: you can define the increment value and a speed factor. the speed factor comes into play if you turn the knob fast(-er). So it's more a matter of multiplying then dividing. Dividing is not really neccessary, just turn the know slowly...If you do not want a fine granularity you should buy encoders with less detents per revolution.>I have some small encoders without detents, that have the>similar output though, it works okay if turned slowly, but>gets a bit messed up if rotated fast.

Hi guys,Maybe this circuit will interest you too: http://www.interq.or.jp/japan/se-inoue/e_ckt10.htmHm

>Maybe this circuit will interest you too: No, not really. It's much easier, cheaper and more reliable to choose an encoder that does not need an electrical circuit but can be connected directly to IOCards.Nicowww.nicokaan.nl
