Default Need MSH51645 desperately!

Does anyone know where I can get the MSH51645 (Brain/IKON cable to Frsky receiver)? My build has been held up waiting for this one part for over a week and it is killing me waiting to get my new build up in the air. The only supplier in Australia is on holidays.

If anyone here wants to sell me theirs, I will pay shipping and double the retail. Ebay/Amazon don't have it listed in Australia. I have one coming from MSH but it will be around a week, after dumping an order with another supplier after a week with no updates.

(My spektrum transmitter is away for repair so I have no alternatives)

Cheers.

Is it the same as this cable but with the smaller white plug?

Yes, the other end has the plug to go into the fbl satellite port.

What receiver are you using? Most FrSky receivers have an uninverted signal pad you can solder to. This eliminates the need for the MSH cable.

I just read now that your cable request is only to be able to temporarily use a FrSky transmitter while waiting for the repaired Spektrum transmitter to be returned to you.
Please note that the MSH51645 cable is only used to have telemetry and integration on the transmitter (display and modification of flight control unit parameters directly from a menu on the transmitter).
If you have such a "desperate" urgency and you can give up Telemetry and Integration, the cable is not a necessary and indispensable "requirement".
You can select the S.Bus protocol icon (as explained in the lateral instruction is used for Futaba, Hitec, FrSky receivers) and, following the wiring diagram shown on the next page, connect the S.Bus output of the FrSky receiver directly to the CH3 connector of the Brain2 with a standard famale/female cable as that supplied with each Brain2 unit.

Thank you a million for the information and support! Just to clarify, the hold up and muck around sourcing the MSH51645 cable was originally the fault of another vendor. Giving up on them, I contacted and ordered from MSH Electronics, they have kept me updated regularly and have done everything possible to get the part to me as soon as possible. Outstanding customer service!

Actually, is there any particular reason why in "classic" Futaba setup CH3 port is used to connect SBUS, but in OpenTX/FrSky setup SBUS goes via SAT-1 port?

It would be more elegant solution if CH3 would be always used for SBUS and Smart Port would be optional, via SAT-1.

It would be also more safe solution: no additional inverter on SBUS signal (one point of failure less for such a critical signal as SBUS) and easier to convert to OpenTX/FrSky setup if one would decide to use telemetry.

You can also make DIY inverter:

Download Gerber files, order PCBs, and yes - you need to solder all three components there .
