While I only see one unit on the Jet-Tronic or Dreamworks website:

The photos clearly show a difference. The left photo is from dreamworks site and the right photo from Jet-tronics site.
Notice the input next to the gear output and a slightly different dial.

So the question is, Are they different units?

the photo on the right is how my 4 sequencers are.

Is there a hard wired input line?

Nope just plugs for rx/gear and 3 for the doors

So where is the input plug located?

Bob,

It may just be an old pic of the product, and now the product has been updated(?).

George, That's what I figured.

Yes the old one only one input .The new one two input. Same programming .

Thanks JC. You should come to the EDF Jet Jam next May. Have a look here: http://www.orvrcf.com/

Hello Bob , i did not realize was you.. Look like a good spot with a decent runway .I will love to attempt ..long long trip for me . But I still fly and love EDF will be nice to see all the friends.
A bientôt peut-etre and happy new year Bob.
BTW: I had the same reaction when I got the sequencer and I was very confused... I building a Christen Diffusion Mirage . But careful with this device because some servo will not sequence adequately Maybe because of the DMSS but not sure!

JC Thanks for the info. FYI, DS will be there.
