any chance you could post a link to the butterfly " AKA" crow videos?

Central Box question: is there a way to get "just a few more channels" with the CB200? The plane I am working on does not really have room for a CB400, so I am using a CB200, but I need 16-17 channels. I could fall back on matchboxes for the flaps and rudders (it's an F-18) to save two channels if I have to .. though I really prefer one channel per servo. And I'll be using two receivers (probably 1x2.4 and 1x900 .. maybe 2x2.4).

I am moving away from Futaba, but on that system this is easy with another S-Bus decoder.. sigh.

Since the CB200 does not have an EXbus output like the CB 400 [Edit: this is incorrect ... see below], I think I am stuck. Funny, since with the CB400 you have 24 channels and would not be stuck anyway, but with the CB100 and CB200 you might want to extend but they don't have EX bus out.

Maybe set the two RXs to PPM out and "tee" each one into a CB200 and a CB100? But lose the ability to see the CBs in device explorer?

thanks all
Dave

i think that's wrong. exbus should be on all CB's. 700.00 just to have EXbus is way to much. thinking back i could have saved myself 200.00 and just went with dual receivers . i could have used two 10 channel receivers and had 20 channels vs. only 15 with the 200. don't get me wrong., i like the DS-24 but i think you wind up spending more money for less at times.

Yes, the CB200 does support EX bus INPUTS from the RXs .. that's how I normally use it. But (unlike the CB400) it does not have an EX Bus out.[Edit: this is incorrect! see below!].. which is what I could really use .. then I could hang a CB100 off the EX Bus output and get the add'l channels. Esprit has a video of this sort of setup with the CB400 talking to two CB100s, one in each wing, using two of the EX Bus outputs from the CB400.

On the CB200 and 400 you can set EXT1, EXT2,and EXT3 for EX Bus output which can then be used to drive a CB100 or one of our new Expanders from Digitech.

You can also remap the extra ports of the receivers that are connected to the CB. With either of these solutions you need to watch the power requirements of the devices you are connecting to.

i very new to jeti. i come from many years as a JR owner. thought the jeti equipment is more advanced ,it's also very complicated to figure out at times. though JR,futaba and spektrum are more limited they are much easier to learn . to jeti's credit ,they do have the best support system i have ever seen. as usual ,i'm confused as to the 200 does support EXbus going in but not coming out?

Dave, in Device Explorer, assign channels 16 and 17 to outputs ports 1 and 2 of your RX3. Power patch port 3 of RX3 (a Y from one of the CB200 servo outputs). Output 4 of RX3 goes to CB200 as usual.
Use low power demanding things as channels 16 and 17 connected to RX3.
That's the way I have it in some of my planes.
The important issue is the power patch !!! CB200 won't handle more than 200 mA from ports RX1 and RX2.

Regards

Jack

F1, that is interesting. I was going by the CB200 manual, which does not show an ability to set a port to EX bus output. But I did not actually fire up the radio and run device explorer.. and SURE ENOUGH!!! .. you CAN set the 14/15 outputs to EX Bus. This is awesome! Dumb me for not checking the actual device and trusting the manual. Perhaps they never change the manual when they add features and you have to read the release notes..

And, thanks for the pointer to the Digitech devices. The plane I am retrofitting has a bunch of stuff (lights, brakes, retracts, ...) in a remote control board in the nose, currently fed by a single S-Bus line .. I have a SlinkE device (https://www.rconix.com/collections/s-bus-converters) that translates EXbus to Sbus .. so I am golden .. I just set 14 or 15 to EX out, then hang a SlinkE on it and feed the Sbus signals. I can even use the same channel numbers. I'll make sure to feed servo power instead of the EX output pin power. Perfect!

Jack, thanks for your insights as well. I did think about using the RX outputs directly, and I do understand the power limits .. but I did not like the idea that it only used one RX which sort of defeats the purpose of dual RXs with a CB. Agreed it would likely work just fine .. but not as elegant ...

This is RCU at its best :-) Thanks Guys!

Dave

No Dave .... "you use both receivers" !! Only that channels 16 and 17 are connected to one of them ... it really doesn't matter to which one.

Just to make sure I understand. "Both receivers" are used for all channels except 16 or 17 .. the CB picks the primary or secondary .. but 16 and 17 can only be fed by the RX they are connected to, right? So in the (admittedly unlikely) scenario that one of the RXs has no signal (e.g. one might be 2.4 and one might be 900, and there is some interference on 2.4), and that's the one with channels 16 and 17 .. then there would be no signal for 16 and 17.

Is this correct or not??

Maybe some Jeti magic I don't know?

You should NEVER connect any devices that use any significant power to a receiver powered by a CB200 unless you add additional power inputs directly to the receiver. The RX1 and Rx2 ports of the CB200 for example are capable of 300mah MAX!!!! A single servo connected to a receiver powered only by the CB200s RX port WILL destroy the central box and most likely result in a crash unless you also power the receiver directly from another power source.

Dave, both receivers are receiving and sending 24 channels to the CB via EXBus.
On Device Explorer you define which of the 24 channels correspond to each servo output of the CB.
Also, on Device Explorer you define which of the 24 channels can be outputted thru the servo outputs of RX3 (or whichever receiver you use).

And yes. If the receiver where you have 16 and 17 connected dies, those channels are lost ( use them for wipers and horn )

Absolutely correct, use 16 & 17 for non-essential things such as lights etc

Hi Dave
we make a EX expander and a Servo extender for Jeti.
this works by connecting it to a free EX port , and you have a extra 2 or 4 Servo ports.
it has even fail safe option and programmable thru the jetibox emulation.
you can asign any of the 24 channels to it..

Dave,
just to add to Sandors description above, the "2 servo extender" (top image in Sandors post) also gives you two additional EX ports for connecting up to 2 EX Bus sensors. This effectively makes it a "Y" cable for EX Bus sensors at the same time it gives you 2 traditional servo outputs.
The "4 servo extender" (lower image in Sandors post) does not give you these extra 2 EX Bus ports, instead it gives you 4 traditional servo outputs.

thanks all. I went back and edited my original posts to note to error in my initial statement that CB200 does not have EX bus out .. since it does!

I hooked it all up with channels 1-14 run by the CB200, pin 15 of the CB set to EX Bus out, and the remainder of the EX signals translated to S-Bus with the same channel numbers via the SlinkE device connected to pin 15, feeding the Sbus line to the devices on the nose of the jet, power fed from a servo port on CB200. Works like a charm :-)

I may do some further testing .. perhaps since pin 15 can also be a servo output, settable to EX bus, it might do more current than a dedicated EX bus output and not have the EX bus pin current limitation.

thanks for the clarification on the devices, Carsten. Do you and Sandor have that new Jeti device for sale yet?

Dave
