MultiPlex Receiver and Jr9XIi

[mave]

Anyone knows if the two are compatible?

Chances are no if the RX is IPD?Its something like PCM or Dual Conversion thingy.You have my freq range module?If have can try my R50 this Sat morning?

It's the other way around. Any FM Tx will work with MPX IPD if it can transmit in PPM mode. JR9XII can transmit in both PCM and PPM modes.

Hope this clears the air.

So that means IPD is actually PPM???
I got the impression IPD is a different technology other than normal PPM that the MPX Tx transmits

Ok now I understand. IPD is actually a filtering technology that dampens the glitch instead of having a PCM lockout. Am I right? I'm feeling so clever

Hmm... just thinking...

since IPD has no header, parity, etc. Then basically it has no way to identify whether a packet is valid or not. Unless, there are data checks embedded within the data stream itself. However, since the receiver is compatible with other transmitters, then it can only mean two things, it is either there is no data checked in the data stream, or the data check is not unique to Multiplex.
Also, most receivers, will hold the last positions. Don't think it is at the TX end. I remember my Futaba 3pk need to send the data to the rx before the rx can do failsafe. Also, i tried before, using a different receiver(same frequency and band), it will not react to your input. Somehow it is a two-communication between this TX and its HRS rx.

But guys, back to my question, if JR is compatible to Multiplex, do we bind the two together as per normal?

Lets do the test this Sat. You will find out.

[mave]

well, ok... Thanks.

You don't sound excited....

Anyway, logically need to bind the RX to the chn the TX is radiating.

[mave]

ha... its because I am thinking about my schedule for this saturday...
