Question.

Looking at this thread in RCG, https://www.rcgroups.com/forums/showthre...-XG11MV-Tx

I saw this in post numbers 4 and 5

Post number 4 by Antic Bipe
Hi Jim, does the XPS JR 11X module support all 11 channels when using the DSM modulation? Your module will however require an external aerial if used in the XG11MV. 

Post number 5 by you
Yes, it does support all 11 channels.

I am not sure if they use serial (115.2K baud) like some of the DSM modules require, or the manchester encoding that the JR11x uses.


So my question is could install your JR-11X internal module into the XPS-J1 case upgrade w/antenna connector and use that module in the XG11-MV to use it with a RFU or Nano when the XG11MV uses DSM mode?
 
thanks,
Bill

Hello Jim,
I put a Nano on the XDP and this came up in the display.  It says XPS-12T with no firmware version.  The picture is the old 10 channel receiver. See attached.  But when I ran updater60 on it, it showed as Nano-E V4, with a firmware version of 1.0

For many years I have been using XPS receivers with XPS modules in Multiplex 3030 and 4000 series without a problem.To back up these ageing radios I purchased a Radiomaster Max edition so I could use an XPS  JR module and continue to use my XPS gear if these old radios ever failed.However,I am having trouble binding the modules to the receivers. One of the modules I purchased when the new batch became available recently and the other two came from an aeromodler in South Africa.(Iam not sure which is whitch now as I cant tell them apart) I have been able to bind one 10 chanel receiver to the radio but it wont always hold the bind when I turn it off,also the first chanel produces a third elevator chanel instead of an aileron. If I shift the chanels from 8 or 10 to chanels 2 to 9 I can sometimes get 8 working chanels.I have purchased the XPS gear over many years with only one return for upgrade quite some years ago,also I have not yet tried to bind any of the diversity receivers .Iam using the ppm setting on the Radiomaster with preset settings on delay and frame. I have not downloaded any new software to the radio,its only one week old. Any help would be greatly appreciated.

Jim,

I was thinking about the latency in my RC systems.

I believe that my Futaba 9C transmitter delivers a new set of channel positions by way of PPM to the XPS transmitter module every 22,5 millisecinds.

Using the XJT-D16 protocol the Taranis delivers a new set of channel positions to the XPS JR-type module every 18 milliseconds.

This means I gain about 4.5 milliseconds using XJT-D16.

If I happened to be using all 16 channels I would be about twice as fast with XJT-D16 than I would be with PPM.

Is that correct?

Thanks,

Paul

Jim,

On the RFU's coax antenna leads, what is the minimum bend radius that will not cause any reduction in signal strength?

I understand that the bare tip must be kept straight, and that the angled antennas must be at least two inches apart.

Thanks,

Paul

Jim,

X16 setup. TX16S. Have set up all ch OK.
Not getting the sequencers I want.
Retracts and doors, Ch 5 on 3 pos switch.
X16 Ports A2 and B2 output from Ch 5.
Servos work OK.

Now to the sequencer: Trigger at 1500.
Tx Ch 5 Sw up Seq#1 triggers doors down. Port A2
Tx Ch 5 Sw up Seq#2 triggers gear down.   Port B2
Not set up yet.
Tx Ch 5 Sw dn Seq#3 triggers gear up.        Port B2
Tx Ch 5 Sw dn Seq#4 triggers doors up.      Port A2

When all sequencers disabled, servos work. Expected.
One enabled, wrong servo works.
Both enabled, nothing works.

So tried duplicating Ch5 as Ch13 in Tx.
Ch 5 Seq#1  doors down. Port A2
Ch 13 Seq#2 gear down.  Port B2
Same thing.  Tx outputs do show in X16.

From reading the X16 manual am I misunderstanding the process?
Quite possible.
Can set it up from the Tx, but reckon that the X16 should do it too.

Cheers,

Jim,
When are you getting more in stock. Want to convert my Heathkit single stick radio.

Hello Jim. I wanted to know if you think using the X10+ is ok for use in a 120cc 3D aerobatic plane. I have two of them and before I buy another X24, I was hoping I could use the X10+ instead.

Thank you in advance.

Regards,

Robert

Jim,

I am considering a new transmitter and I would want one that could talk to XPS transmitter modules, receivers and channel expanders with the most direct, efficient protocol.

I have a vague recollection of a post somewhere in the old forum that states that one brand of transmitter used a protocol similar to your Xtreme protocol.  I cannot find it using the search.

Can you recall what may have been posted about this possibility?

Thank you,

Paul

I have just installed the JR Tx module into my Taranis, trying to go thru the radio setup.  I have set it to the external module, PPM, and it is asking for the frame rate.  It is showing 22.5ms, 300u.  I assume this is correct?  I have not found this addressed anywhere.
