Hi Guys

I have a question. I was on the opencockpits website as I wanted to purchase a Master Card, which I am still going to do. I want to buy rotary encoders from them but I am not sure which one's to buy. I am going to use them for functions such as altitude change, heading change ect.

Any input would be much appreciated as I don't want to buy something that's not going to work.

Thanks Guys

Hi,

At OC's sales you will find only one rotary encoder, the 3T7

You can connect this encoder directly to the Master Card.

Do not forget to buy a USB expansion card too.

regards,
Nico

Your going to have to investigate your interface card. some cards accept multiple types of data.

1-bit, 2-bit, Grey code.. etc.

You have to find out what kind your interface can sustain, and go from there.

Hi Kiek

Will the 3T7 work for Heading change and altitude change ect.

Thanks

Yes, of course.

You can give a look at my blog (link in the signature), as this morning I posted my small results about shopping for rotary encoders around the worldwideweb.

Happy flights.

I am placing my order right away. This information was helpful.

Thanks Guys, will let you know when I recieve the card + usb expansion card.

You guys are stars, thank you , thank you , thank you.

To all who help out, I Appreciate it.

I'm sorry, but the information in your blog about the CTS288 is not right. The CTS encoder is always 1/4 cycle per detent. The one you can shop at OC has 16 detents, so it is 16detents/4cycles.

You can only connect grey type encoders with 1/4 cycle per detent to the OC Master Card (and 16 detents is the optimum speed, 24 detents might give problems). More info for OC and grey type encoders here:

Thanks Nico,
You've always been my hero :)

I'll update the post on my blog and you worth a "kudos" for it ;)

Kiek,

The 3T7 does not have a built-in "Push" switch according to the specifications correct? Would the Rotary Encoder (REWP with built-in "Push") from FDS work as a heading select on the OC boards. I guess I'm going to have to build an MCP again since no one is making a ready built 767 MCP

Yes that one is also a CTS288 based encoder, it works fine with OC, I have these encoders too.

You are right, although you can use the OC MCP737NG as 767 MCP with my lekseeecon program. All functions all there, but the look is ugly ;-) (I have it myself).

You can purchase the CTS 288 encoder from Digi-Key in the US for around $2,50 each. It is part number <code>CT3002-ND.

be aware that that there are different versions, take the 16 detents one.

hello dal900....
cts288 (3T7) from OC does have momentary push switch. i have ordered 20 of these for
various applications. i'm using them on my efis units for incremental/decremental control of values and the push switch to select Mins,Ctr,Tfc and Std.
here's the datasheet
http://www.ctscorp.com/components/datasheets/288.pdf
if you look at the image on the OC page, there's 5 pins out of the component. 3 for the encoder and two for the push switch.
very nice quality component, i love 'em.......
best regards from wales ..... ian

Yes, Nico. I found that out the hard way. I was testing an Alps encoder and it wouldn't control correctly. It was working but, not the way I need it to work.

I searching the web for answers and advice I found this thread. I went to you site and vcimmino's blog. Good info. I made sure the ones I ordered were 16 detent units.

They have the units with the built in switch in the catalog but were out of them, at the time of my order.
