HC3SX+ SBus + JIVE BEC = Is this possible?

[drfrankencopter]

Hi All,

I'm integrating equipment into a TREX700E. I've got a Kontronik Jive 120HV ESC and was looking to use the internal BEC. The receiver is a Futaba R6208SB which I had planned on connecting to the HC3SX via Sbus.

But I'm a little confused regarding how to connect, and whether it will all work together.

The straightforward part is connecting the receiver to the HC3SX. If I want to do this via S-bus it's just conenct the sbus port on the Rx to the 'Sum signal' port on the HC3SX (just below the programming port).

After that, things get a little murky.

The HC3SX manual states that it should be connected directly to the power source, and should be used to power the Rx. Okay...

The manual also states that if I connect to it via SBus that the pitch servo input becomes an available output.

Here's the manual text on power connections:

Please note when connecting
• As high servo currents can occur, a voltage supply must be routed directly to the device!
Also, the receiver must be supplied via the FBL system, not vice versa.
Use one of the following possibilities for the connection:
a) Battery connection / head 4 (in case no 4th head servo is used).
b) Programming connection (in case the PC adaptor is not connected; for programming the supply via receiver is ok).
c) In case a PWM receiver is used, the supply can be connected to the gas output. If used, a BEC controller is
connected here anyway.
d) In case of supply from a BEC controller, route a parallel supply cable (e.g. Y cable) to either battery or programming connection
of the FBL system. This connection must not possess a signal line, i.e. the third pole may have to be interrupted.
d) For using only the tail gyro of the FBL system, you can either do a set-up with deactivated head gyro (still using the internal
mixer), or only connect the tail gyro cables, plus one of the three-wired connectors (aileron or elevator input) only for
supplying the receiver with power from the FBL system, by connecting it to any vacant socket of the receiver; preferably
with disconnected signal-wire.

So, what should I do? Connect the Jive slave to the battery port? Where should the master connection go...should it go to the Rx, or the HC3SX governor port (this doesn't seem right since the Helicommand manual suggests that if you want to conenct to the governor port you should do this with just a signal wire)? Will the Rx receive power through the SBus link to the HC3SX?

Sorry for the long post....any guidance would be greatly appreciated

Cheers

No problem, the solution is easy:
plug the S.BUS RX into the sum signal port of the HC. That's correct.
Next to it (port 3), plug the ESC/BEC cable. In case you have a slave cable too, plug it into Bat./Servo4 port (I guess you do not have an H4 linkage?!).

That's all. Nothing is connected to the RX any more, no ESC, no BEC, no servos, no slave BEC, no battery.

Hope this helps.

I am running an identical setup on my Synergy E7

Helicommand HC-3SX
Jive 120HV + (Throttle and Slave)
Futaba R6208SB

I have the receiver plugged into the sum signal channel, Jive signal into throttle and Jive slave into head servo 4.... working flawlessly!
