Hi,

I am making an attempt to use the SBus option for my T-Rex 550L Super Combo. It comes with a Microbeast PLUS FBL unit and I have already successfully set it up using the standard receiver configuration with the R7008SB in Mode A. If I want to use the SBus, which mode should I use? Mode B?

Thanks!

Yes, you should use mode B

How do you verify your in Mode B?

Red LED blinks two times

Just like it says in the manual.

Just like it says in the manual.
Exactly, I have the manual and have (I thought) set mine several times.

I "assume" you set the transmitter to the 12 channel setting first. Then you set the mode on the 7008 to Mode B (two blinks).

Whenever you start the 7008 sequence, you get 1 blink. Press the button, you have 2 blinks, release, then press the button and hold it until you get a continuous fast blink, power off, and you're done, Correct?

How do you verify the 7008 is in the 12 channel, Mode B setting?

When I go through the sequence again, it starts with 1 blink.

I want to verify that the 7008 is in the correct mode.

Will it hurt anything if I leave it in Channel 1 mode?

Dennis

PS: Advise if I am not setting the 7008 correct. Some have given advice that's not in the manual.

I have followed the instructions in the video below. Mine operates just like the video states it should.

Mode B

If you are using the SBus and it is not n the correct setting then it won't work properly. If it works properly then it must be in the correct mode.

That's what I was thinking, but I wanted to be sure.

Mode B

I can't get mine to swap to Mode B!

And you're correct, if it's not on the proper setting, it will not work.

Mine will not work while in Mode B, swap to Mode A (transmitter) and all works fine.

So I am in Mode A.

Mode B

Yes it happened to me too. Are you using the SBus as instructed in the wiring diagram in the manual?

Yes, I had the schematic sitting right next to me when I was setting it up. Followed everything as instructed.

Can you post a video showing the process you're going through to put it in mode b. Also show the connection you using to test/very it's in mode b.

It's already set up and operating correctly. As stated, follow the instructions exactly as stated. After you obtain the "2" blinks, hold the button down 2 seconds or more, release, then cycle the 7003/7008 a few times. It retains the setting.
Mode B
If you are using the SBus and it is not n the correct setting then it won't work properly. If it works properly then it must be in the correct mode.
The above quote is 100% correct.

Thanks for all the help, Dennis

Glad to hear you got it working correctly. Your earlier post said
I can't get mine to swap to Mode B!
Also, no need to do this on the R7003 as the default mode includes S.BUS.

One thing, Mode B is not the "12 channel mode". The 4 different modes simply define the pinouts on the RX. It has nothing to do with "number of channels".

MODE A - pinouts 1-8 output channels 1-8. SBus2 port is the SBus2 port

MODE B - pinouts 1-7 output channels 1-7, pinout 8 is now an SBus port. SBus2 port is still an SBus2 port

MODE C - pinouts 1-6 output channels 9-14. Pinouts 7 and 8 do nothing. SBus2 port is the SBus2 port.

MODE D - pinouts 1-6 output channels 9-14. Pinout 7 does nothing, pinout 8 is now an SBus port. Sbus2 port still remains an SBus2 port.

Summary - the SBus2 port is ALWAYS an SBus2 port in all 4 modes. MODE B and MODE D turn pinout 8 into an Sbus port. MODE A and MODE C eliminates the standard SBus port and you use pinout 8 for RX power input or you can use it for channel 8 output (MODE A) or channel 16 output (MODE C).

14SG settings -

FASSTest 14ch - 14 channel output with telemetry. Telemetry sensors use the SBus2 port.

FASSSTTest 12ch = 12 channel output but NO telemetry. This setting has a lower latency response than the FASTTest 14ch.

FASSTMulti - 14 channel output, NO telemetry.

FASST 7ch - 7 channel output, NO telemetry.

S-FHSS - different protocol than FASST -must use an S-FHSS compatible RX. 8 channel output.

FASSTest 12CH
FASSTest system receiver mode. Applicable with receiver voltage display. Up to 12 channels (linear10+ON/OFF2) can be used. Telemetry Sensor cannot be used, but the response speed is a faster than that of the 14CH mode

Understood, the above states the response speed is faster in FASSTest 12CH Mode. This is what Futaba pointed out when they advised me to use this mode.

What is your thoughts on the faster response speed in FASSTest 12CH Mode?

Is it worth the change?

I am already using it now, but I could switch back for the right reasons.

Thanks, Dennis

PS: Thanks for your reply, it also helped me to further understand the Futaba system.
FASSSTTest 12ch = 12 channel output but NO telemetry. This setting has a lower latency response than the FASTTest 14ch.
This part in your response has me confused a little, "this setting has a lower latency response"

Again, I am open for all suggestions making sure I get everything set up, and set up right for my Heli's, and hopefully helping a few others in the process.

I am not good enough to notice any difference between 12ch and 14ch w/ telemetry to be honest.

Latency, measured in milliseconds, is the time it takes between moving the stick and the servo actually responding. Between the processing time in the TX and the processing time in the RX there is always a delay in actual response time. The lower the latency the faster the response time. We are only talking about a few milliseconds and again i cant tell any difference. Maybe professional or competition pilots can but i cant. If you are not using telemetry then i guess you might as well take advantage of the 12ch faster latency.
