New DSMX sats giving nothing but errors
I picked up a pair of DSMX satellites for my 550. I DLed the latest software and in got them bound to my DX8.
I had been having trouble with my DX8 but I sent it in and they fixed it up. I flew my 550 all day saturday on the DSM2 sats without any problems.
So, on the bench as long as I move everything easy the event log shows no problems with the new sats. But, when I move the pitch very quickly up and down, it will skip and hesitate frequently. Checking the log shows many missed inputs on all channels and frequent antenna switching. I was suspicious of battery but there were no low voltage messages. There were a couple other errors thrown in but they were primarily missed inputs and several in the same time frame.
I tried to rebind at the old 22ms frame rate but it only wants to bind at 11ms in the DSMX mode. It doesn't do this when I bind in DSM2 with these same sats.
I really want this to work with DSMX but I am having my doubts!

From My understanding from all I have read is, V-bar and some other FBL units will only work with DSM2 at the moment. Maybe a future V-bar update will be available?

In reality DSM2 has been flawless and DSMX is really only needed for big events. Even at big events like IRCHA, very very few had issues with DSM2.

Binding the "old school" way is still cool IMO.

Cheers,
Raven

Have you updated your firmware to the latest version? 5.18

The latest update was supposed to enable DSMX

Not sure what version software or where to find it. I looked through the menus but didn't find PID or software version.
SPMTX201.SAX dated 3/20/11 is the software file I installed.
A104800494A27 is one of the tag numbers in the battery compartment and HO011CM is the other tag number.

I re-bound it half a dozen times both in DSMX and DSM2.

In the VBar setup do you have it set for Spektrum 1-2 Satellite DSMX? There are two options for the two satellites in the latest firmware. Also what frame rate are you using?

I hve tried both DSM2 and DSMX in the VBar program. It errors only in DSMX. I want DSMX for events like IRCHA on all my helis.
It will only bind with 11ms frame rate in DSMX. I can only get it to bind at 22ms in DSM2.

When you connect your Vbar to the computer, the installed firmware version will be shown in the lower right corner of the program screen

Go into the System Setup menu (press and hold scroll wheel while turning on TX). From there you go to the Frame Rate function to change to 22ms even if you bind at 11ms.

The thrid screen of the System Settings function will show the firmware in the lower right corner. It should say 2.01 for DSMX.

I missed that third screen this morning. I was in a hurry to get to work on time. It is 2.01.

I'll hook up the VBar again and check but since I just DLed the latest software last night and installed it, it should be either 5.1.7 or 5.1.8. I have only seen 5.1.7 listed but I thought when I loaded it onto the VBar, I thought it said 5.1.8.

i am using the v bar 5.1.8 on my t rex 550 with dsmx satellites and it works really good, i was able to bind it on hi res and with 11 ms frame rate, i had to update the software and firmware too ,after that it did bind with no problems,just make sure your rx pack is fully charged (if you use one). it should work with no problems....

+1. Using DSMX with a DX8 5.1.8 vbar no issues.

After binding in DSMX mode, did you recalibrate your TX? Are both satellites DSMX?

Problem solved! I was using a separate battery and switch to get it set up. I had tried several batteries but kept having same problem. I decided to try it with the flight battery and ESC. It worked just fine. After that I tried one of the previous batteries that had the problem but I plugged the pack straight into the VBar. It worked just fine. I tried one last time putting the switch back in line and it started failing again. Apparently, the switch has enough resistance the says were browning out. I thought the sat LEDs flashed on brown outs. Obviously not!

That is one thing I do not like about the DSMX upgrade....no more flashing satsif you lose power. Harder to diagnose issues if any Team MikadoUSA 480XXTreme, 550SX, 600SX, 700XXTreme, 800XXTreme!!
