Yet another Naza Assistent problem

[maxwelltub]

Hello, I have been trying to get the Naza assistant to work with my F450 for a few days now. I have done extensives online searching on forums and other sites to try and troubleshoot the problem. The problem is getting the assistant to respond to stick inputs from my transmitter to calibrate the flight controller. I have run through the common forms of problems that people often have. I downloaded, an unzipped the usb drivers for a 32bit windows xp, I installed the driver successfully and then tried reinstalling it multipul times to try and get it to work. I have updated and installed new firmware to my controller, I made sure to have the most updated version of the assistant. I also checked my TX and RX as well as the connections between the RX and the controller. When using the assistant I make sure to power up my TX, then the Naza, and then plug it into my computer.

The assistent has worked briefly three times, seemingly at random. The first time it worked for a little longer and when it was working seemed to being working fine, that is to say I could calibrate all channels and properly set up manual and altitude mode. I dont think it was able to write properly once I was done, at least it never showed a write status bar. When I removed the quad from the computer and tried to arm the motors nothing happened and eventually it went back to a flashing red. The second time it worked the calibration was responding to stick inputs from the TX but the channels were not reaching their endpoints on the assistent. All trims, sub trims are centered and the endpoints at 100% on all channels of the TX. I have run out of ideas and hoping that someone from DJI can help me fix this problem.


[FONT=arial, sans-serif]The TX that I am using is a Spectrum DX7 and the receiver is an AR7000. I had been using Heli mode, but recently tried ACRO mode without favorable results. I am running Windows XP service pack 3 on a Mac Pro through the program Parallels. Before you say check the USB drivers just know that I have done that multiple times, the fact that it works intermittently indicates that it is probably not a driver issue. The TX and RX have been binded and rebinded several times and tested with other servos. [/FONT]Any help that could help lead to me fixing the problem would be very much appreciated.

if you have windows, you should have device manager, or something that shows everything connected. on win7 it shows printers, anything hooked up externaly. Do you see a usb driver loaded and says something about dji naza? when you plug naza into your pc and fire it up, does MC Controll show green? does naza have a green light?

When you change something in calibrate, it is all done at the radio, the finish click is a write click to the controller and your done. when that finish button is hit and with throttle at exactly 50% they should all show green and centered, can shake a tad but is alright and when you move the stick, will all show the same movement to the endpoints

the only time you need to write is changing gains or changing the aux input assignment or changing voltage stuff. the number will show red and you have to hit WRITE to make them go black, it is slow to write, but you see it happen.

The VU led goes solid green when plugged in. The driver does show up under ports when the unit is plugged in. The Naza unit itself has a solid red light when powered on, that hasn't changed. All the other info is good to know for when I get it working past the calibration.

Green VU means it sees the pc, no driver, that flashes red usually. is the motor control off show a green box like my first attachment?

read page 38 of the manual v 2.1, says hover till solid light emits a spark, that doesn't sound right

So in my experience but only from win7 to naza is it's never hiccuped, farted, spit........ plug it in, do a calibration, set the man, atti, gps atti to a switch and make that work in the same screen, then i go to gains and give the manual ones a straight 120 across the screen, atti make 80. Then i goto voltage protection and shut that off. hit write, takes a minute but stuff on the screen flashes

i was going through the rest cause you couldn't tell if it's writing or not sounded like you never saw a write button or expected the software to write the naza and it doesn't, you do, except the calibrate finish button

Well I am happy to say I got it working. I don't know what it was but it just works like it should now. Calibrated and ready for test flight. Basically I took the whole thing apart and put it back together. I had read somewhere that on the AR8000 the brown servo wire is supposed to be facing up, I figured I would give it a try even though I had tested it that way before. (I am using an AR700 RX) Didn't work, but when I plugged them back in the way they where before, yellow wire up, it started to work. I also reconnected the satellite RX which I had tried before with no additional luck. For what ever reason, (lose wire?) its working now. On a positive note I know my f450 way better now then if it had just worked right off the bat. For anyone else scanning forums to look for a solution, my advise would be to take the whole thing apart, reinstall everything, and then put it back together very slowly and carefully. I still don't know what it was that was wrong with mine but the complete break down and rebuild seemed to do the trick.
