HI, guys.
Just ordered Openpanzer board & Benedini sound system for my Matelbox Luchs project.
However, I just found out that the TCB is connected via SBUS or Ibus, but no standard 1-4 ch cables. and its working Voltage is from 7- 15V.
I wondering if anyone has connected Futaba R3008sb or other Futaba Sbus receiver to the TCB? My radio is the Futaba T10j and the last thing I want to do is to purchase a new radio.
Also, as for the input voltage, since the tank is powered by 24 acid battery, I certainly need to fit a convertor. However, anyone know the max amp of TCB allows?
the ESC I use is the Sabertooth 2*32.
many thanks
Larry

Hi Larry,
The TCB is compatible with the Futaba SBus protocol, they are the ones that invented SBus. If you get a Futaba SBus receiver you will have no problems, and you will get a lot more channels than just 1-4.
Yes, you will need a BEC or similar device to power the TCB if you are using a 24 volt system. The "max amps the TCB allows" is a confusing question. The TCB itself draws very little current. If you are using the onboard Motor A & B outputs, for example to drive your turret motors, note they can provide up to 2 amps max each (so 4 amps total). This may not be enough current for your turret, only you will know. The TCB can also provide up to 3 amps total to other 5 volt devices (lights, servos, etc). So size your BEC or converter appropriately. The more relevant question is, what is the "max amps your BEC will allow."
Of course you can still power your Sabertooth directly at 24 volts, it does not need to operate at the same voltage as the TCB so long as they share a ground connection. And of course your Sabertooth will still be able to provide up to 32 amps to each drive motor.
Keep us posted on your project! I have been waiting for someone to use this in a 1/6 scale model.

HI, Lukez
it's very helpful. Thanks a lot.

Hello Larry
i have already built in what you are asking for.
radio: Futaba T10J
receiver: R3008SB and also a Cooltech RSF08SB
connected via SBUS to the TCB.
soon i'll test it with some other Futaba RC's and cooltech or corona receivers
no problems. works great great. configuration like shown in the wiki

Guys,
finally, the TCB is with me. However, I got the 1st problem. Radio can't be detected.
I hooked up PC with TCB, and connected with r3008sb via the 8/Sbus port. Linked with T10j, but, OP config says, radio can't be detected. I am sure the receiver is in the correct mode.
Do I have to connect extra power to the receiver at the meantime it is hooked up with TCB?
-
I tried a second TCB. Windows XP installed the driver again, and assigned COM5 to the 2nd TCB. But, the OP config won't connect to the 2nd board.
will it be a quality problem?

well, turns out the 5#DIP switch are set to OFF.

Right, Dipswitch #5 needs to be in the ON position, glad you found that.
Now do you have any issues detecting the receiver?

the TCB still can't read the radio . $_$

To answer your earlier question, no, the receiver doesn't need an extra power source, it obtains 5 volts from the 3-pin connection to the TCB.
Ulrich confirms the R3008SB receiver works, so yours should too. There are two receiver connections on the TCB, try the other one. In other words, you have probably been using the bottom connector which is labelled for SBus, but try the top one too and see if that makes a difference.
Does your receiver turn on correctly? Is there a light or anything on the receiver that you can use to confirm?
I have not used this receiver personally but just looking at images of it, I see there are two SBus connections on it, one labelled "8/SB" and the other "S.BUS2"
I don't know what the difference is but try both of those, and make sure you have the polarity correct. Possibly there may be some settings in your transmitter to enable SBus, I don't know.

It’s spring festival holiday here, all shops are closed. I might want to get a FrSky delta8 later and have another try.

Hi Ulrich
Glad your setup works.
May I ask the configuration of your setup.
1. Is there a switch or setting in T10J which can force the radio using Sbus. Or is it done automatically?
2. Which mode of 3008 you set to? Is it mode 2?
3. Did you purchase the Tcb most recently? Mine is HobbyKing’s 2019 Jan stock.
Many thanks.

I will test again later night on a native PC as it just occurred to me I am running the setup in the VMware on a Mac. Although the Op config can connect to the TCB in the VM, but still there might be the possibility.
Fingers are crossed.

According to page 29 of the 10J manual (http://manuals.hobbico.com/fut/10j-manual.pdf), you need to set the R3008SB receiver to CH Mode B or D. It's not clear what the difference is between those two modes with regards to the SBus output, possibly nothing. I would try both modes, and connect your receiver to the TCB using the receiver's "8/SB" output.
If you are able to connect to the TCB with OP Config then VMWare is probably not your issue, otherwise you would have had a problem already before that.

Hi LukeZ
The difference between mode B(2) and D(4) is the changes in the availability of PWM outputs .

finally, I found it is working with r2008sb.
r2008sb has only sbus, not like the r3008sb which also supports sbus2.
However, only 2 out of 8 position switches, 1 rotary knob can be recognized by OP config. I will try the Delta8 receiver some days later.

Hi,
my experience with every FrSky SBus-Reciever:
all 16 Channels is full supported by TCB

It will work with R3008SB if you configure it correctly. 3008 still uses original SBus out the "8/SB" port, and even so-called "SBus2" is not a different protocol, it is the very same thing only it accepts 2-way traffic. Did you try both CH mode B and D? You have not told us.
Every manufacturer is different in how many channels they pass through over the SBus connection. The 10J is FHSS and is considered to be in Futaba's budget line of transmitters (although it is still ridiculously expensive). Possibly it only passes 8 channels over SBus, or even less. Even without SBus, the 10J has rather more physical controls (13) than it does actual channels (10), so inevitably many of the switches are not going to be used or else you need to configure which ones are transmitted.
It is not clear to me the Delta 8 is going to give you anything different, if the limitation is with your transmitter.

I just looked up at Futaba’s web and found out the R2008sb only supports 8 CH although it has Sbus. It makes sense why only 3 switches works now.
Now I need to save for a 16SZ or 18SZ.hahaha
I will try another 3008 later ,just in case the one I tried is a fake one.

Hi Larry.
sorry for the late feedback.
1. no - but you have two connectors for SBUS. normal SBUS and SBUS2. which one have you used?
(at the moment i am using the cooltech rec and this one uses "only" S-FHSS - the Futaba 3008 T-FHSS. it is too expensive for a tank and i need it for copters and plains ;-))
2. yes it is an orignal Mode 2
3. no, it is older. it is from early 2018 (got 2 more - ordered in Nov and Dec '18 but not tested at all)

Hi, Ulrich
I connected it to the 8/Sbus port on the r3008sb. I got out another 3008 inside my Tamiya Sherman. I will try again.

Ha,
no, not yet. assemble the wiring, etc, at the moment.
