Probleme de reception de trame RS232

Bonjour,
J'ai créer une application permettant de recupérer des trames sur un port RS232, cependant lors du test sur appareil, je me suis apperçu que je recevais les mots supérieur à 16 bits à l'envers, c'est à dire qu'au lieu de recevoir 1003 je reçoit 0310 ou encore au lieu de recevoir 2802 je reçoit 0228.
Quelqu'un sait-il comment je peut modifier ceci pour recevoir les mots dans le bon ordre?
Merci d'avance,
Rémi D.

Essaie cette version. Vérifie également que les controles et indicateurs sont en mode hexadécimal.

Problem with reception

I traveled abroad this summer right after I bought my computer. Before I left I could get perfect reception on my computer's wireless from anywhere in my house, and I could pick up other wireless at coffeeshops and such.
Upon returning I've found I can only pick up wireless for about 10 minutes and then it cuts out (and returns off and on every other minute), this happenes in my house and everywhere else. The problem is not in the wireless because everyone surrounding me can pick it up no problem, just not my computer. Airport itself won't see the wireless at all, but in my widgets my airport radar can pick up the signal full strength even after airport itself has cut out.
I can't find anything on the web about this problem...do I take it to the apple store and beg for mercy?

You could do that. Those genius bar people are knowledgeable. It would be easier for them since you would bring them your laptop.
It sounds to me like maybe your airport card became unseated or antenna connection became loose.

No really. 'a problem with vodafone' is too vague to offer advice.
What is the problem - in detail please ?

[HELP] problem with receiving data through rs232

When I connect my VI with MCU (using proteus to simulate), why does it run stable in only 20 seconds? After that, it seem to be unstable. And when I stop simulation in proteus, why does my VI still run and stop after about more than 10 seconds?
thanks!

Reading and sending speed are 9600. you are right, the buffer was filled up, but I don't know the reasons. If I read 22 bytes in Labview, it will run stable for 20s, when I decrease the byte count, the stable time increase. If sending and reading speed are the same, why is the buffer filled up?
When I stop simulation in Proteus, it still run for several seconds before stop (I think, it run by the data in the buffer). But, if I connect with PL2303 module then disconnect, it will stop immediately.
It sure would be easier to read your pictures if your wires were somewhat straighter, didn't go backwards, didn't run under other wires or structures, appear to enter subVIs at the wrong terminal, or just appear or disappear at the edges of structures.
If your program stops after approximately 53,000 bytes (422,000 bits) no matter how many you read in a chunk, then I'd look at the sending end rather than the receiving end. But I don't have LV 2013, as many of us don't yet, to look at the VIs you sent in the first message.

Iphone 3GS problems with reception, freezes, bugs, SIM Card

I have an all legit iPhone 3GS 32GB I bought last October in the Netherlands together with my subscription to T-Mobile. Everything went perfect until about 3 weeks ago when my iPhone would loose network connection, stay in "Searching..." limbo forever and end-up with "No Service". I tried everything from resetting my iPhone, my settings, to taking in and out my SIM card, to updating it with iTunes etc… It works for a while if I leave it on “Edge” without activation its 3G. But then, out of nowhere, it will ask me to unlock my SIM card, will freeze and stutter while I’m doing so. I would wait for some time before my iPhone will resume normal service (albeit still on “Edge”), by itself, and repeat this nightmare all over again the next day. I can also find it running iPod all by itself even though the iPhone is on sleep. This iPod "demonic possession" is generally a precursor of troubles to come.
Is my love affair with the iPhone coming to a very sad end? Or can somebody save our relationship? Please help!

The insurance company is coming today to pick up my iPhone. They will give me a non-iPhone "smart phone" as replacement for the 6 weeks it will take for the "repair". This is what I'm reduced to. If the iPhone comes back defective, I'm planning to just smash it with my bear hands and buy a Nokia or BB or sthg.
I hate that repair stuff. It's should work fine though. Make sure they really fix it.

My IPhone 3G reception fixed, a new problem - AT&T *real* data speeds

I've read quite a few topics on this forum regarding the poor IPhone 3G reception, and unfortunately 99% of them are emotions, making it very laborious to distill useful info out of them.
Therefore I'd like to post my personal experience so far with IPhone 3g, listing more facts, than emotions. *I hope this will help some of you, and also hope that others will follow a more structured approach to reporting IPhone 3g problems*.
*IPhone 3G Model MB046LL, 2.0.1 firmware*
I got my IPhone 3g black 16gb version in NJ on August 2nd, model MB046LL. I work in IT, and I was overall very impressed with all of its features. However, the device had 2 major problems - 3g reception was highly unstable, and the actual 3g data speeds were far lower than advertised, 200kb on average for download and 30kb on average for upload.
I called AT&T, they said I was in the zone with "the best 3g coverage". I went to an AT&T store, and had my SIM card swapped from #3022 to a newer one, #4022. Swapping the SIM card drastically improved both 3g reception and the data speeds.
Unfortunately, I noticed that my IPhone 3g was picking up not as many bars of 3g as other Iphone 3g sitting next to me. The actual dbm numbers for 3g were also smaller. I would continue having dropped calls. I also noticed that my battery would fully recharge very fast (within 1.3 hours), and would fully discharge much faster than it was advertised. The GPS was acting weird, and the voice quality would sometimes be horrible even with 5 bars of 3g. There were more anomalies with that phone, e.g. download speed of 20-30kb with 5 bars of 3g, among other things. I would diligently take screenshots of every anomaly I saw, and store them on the phone. Restoring the phone to its factory state did not help.
After some time, I concluded there was still something wrong my IPhone, scheduled a Genius Bar appointment, and had it replaced with a brand new IPhone 3g. Having numerous screenshots of different problems minimized the explanations to a minimum.
*IPhone 3G Model MB048LL, 2.0.1 firmware*
I had a chance to compare the new model with the previous one I had - the build felt a bit different. The screen on this new model has a slightly better contrast, too (compared default factory settings).
*The new model, however, has GREAT 3g reception*. Where with the previous model I had 2-3 bars of 3g, I now have 5 bars. The dbm numbers are also somewhat improved. I had a couple of small issues with apps, etc., but I figured them out - found which apps were crashing the system, and deleted them, cleaned up the old backups and the crash diagnostic crash reports from the previous model, etc. Finally all other problems I was having with the previous model are now gone, too, except the quirkiness of the GPS, but I suspect it's the new firmware, and not much I can do about it. I have yet to see a dropped call on this new model.
However this new model identified a new problem, something that I'd suspected for some time: it appears that the problems people are having could indeed be the combination of IPhone hardware/software and AT&T network.
I noticed the data speeds vary significantly throughout the day, even when you sit at the same desk. I noticed the speed drops significantly approximately during lunch time to ~90-300kb for download, would be ok during the day (~200-350kb for download), and would be AWESOME after 10pm - ~0.9 - 1.4Mbs.
One can make a conclusion here that AT&T simply does not have enough network capacity to handle the peak data load, when many people connect on the network. It could be that IPhone's software does not manage very well under such conditions, but I'd would place more blame on AT&T in this case, considering how exceptionally well IPhone performs during other times.
I'd like to point out that although both Apple and AT&T reps were genuinely trying to be helpful, I could clearly see that not one person I talked to on both sides did not have a clear solution how to resolve the problems I was having. Basically, I had to figure out what the problem could be, and use the resources available to try to solve it - be that replacing the phone, restoring from backups, monitoring the crash logs for problematic apps, etc.

I would constructively suggest that you edit your post pretty quickly if you want to avoid a highly deserved, verbal battering from every unemotional, highly rational and intelligent poster on this forum who might take offence to your demeaning attitude. I think to assume that because people who have posted on here have posted at all because they are emotional basket-cases, or in some way out of control of their emotions merely because they have aired their disappointment/disgust/anger with their sub-functioning iPhones is pretty insulting and undeserved. Whatever YOU have written here, or have experienced elsewhere, still only has the value of 1 (ONE). It is a poll of 1. It is an opinion of 1. No more valid than that, no more authority than that.

Probleme bei gleichzeitiger Verwendung von mehreren RS232-Schnittstellen.

Hallo, ich habe ein Problem bei der Verwendung von RS232 Schnittstellen zum Auslesen von Werten externer Laborwaagen. Die Waagen senden mit 1200 baud, 8 bits data, no parity, 2 stop bits. Ich habe mir in LabView7Express ein Programm geschrieben, in welchem ich mit Hilfe des I/O Assistenten VI die Waagenwerte auslesen kann. Zum Zeitpunkt der Programmierung war die Waage am COM 2 Port angeschlossen (diesen habe ich über die WindowsXP Systemsteuerung ebenfalls auf 1200 baud, 8 bits data, no parity, 2 stop bits konfiguriert). Das Programm hat auch perfekt funktioniert. Jetzt wollte ich eine zweite Waage (gleicher Typ wie Waage 1) an den COM 1 Port anschließen. Das Programm habe ich dahingehend veränd
ert, dass ich den Teil für Waage 1 einfach kopiert und im I/O Assistenten den Port COM 1 ausgewählt habe. Waage 1 (am Port COM 2) wird jetzt weiterhin normal ausgelesen, für die Waage 2 (am Port COM 1) bekomme ich immer eine Fehlermeldung: bfff003e.
Ich habe jetzt versucht das Programm neu zu schreiben (nur die Waage 2 am Port COM 1), bekomme jetzt aber im I/O Assistenten einen I/O Error. Beide COM Ports funktionieren (mit dem Windows HyperTerminal überprüft).
Ich weiß da echt nicht mehr weiter und bitte um Lösungsvorschläge, lg axelwo

Dieser Basic I/O fehler ist schwer einzuengen. Meistens sind das Probleme mit dem Deskriptor der Resource. Sind COM1 und COM2 unter MAX sichtbar? Kann man eine VISA session dazu öffnen und einfache befehle testen, wie z. b. "*idn?"? Ansonsten kann es auch was mit der Konfiguration des POrts zu tun haben. Hierzu benutzt man am Besten die Eigenschaftsknoten die mit VISA mitgeliefert werden. Anbei ein Kleines Beispiel, denke das sollte funktionieren:

IPhone 4s - 5.0.1 Reception Problems

Hello all... I have two (2) iPhone 4s. I used to have all iphones (2G, 3G, 3GS, 4)
Never had any problems with the reception. Both iPhones 4s are on the same network .
I noticed that my iphone 4s has a huge reception problem. Even if I have 4-5 bars of signal... the phone is unable to perform a call. I have to try more than 4-5 times in order to make a succefull call... I type the phone number... I have to wait for at least 10-15sec and 80% of the times i get "call cancelled"
Even if I manage to make a call... most of the times ... with NO reason the call drops.
Also in locations where I have 2-3 bars of signal... suddently I get "no service" and most of the times I have to reboot the phone in order to get signal again.
I think that this started after upgrading to 5.0.1 (I was having 5.0 only for 3-4 days... so I am not sure if there was a problem also)
Is it true that all these problems
1. reception problems
2. Not stable wifi
3. Battery drain
are software problems???? Are those going to be fixed on a future update (maybe 5.1) which we are waiting a long time now....!!!!
Please help.... if this is not a software problem....I am thinking on returning the phone in order to get a replacement
Thank you in advance

Well battery life gone down to 81% since 40 mins ago!
Well no other problems as yet but not tried any yet.
So much for QA !!!!
5.0.2 I hope fixes all these problems

Passage RS232 vers USB

Bonjour.
Je travail sur un multimetre distribué par Française d'Instrumentation (FI 2803 MT ou UT803) et l'outil LABView 8.2.
N'ayant trouvé aucun VI sur le site de NI, j'ai récupéré aupres du distributeur les trames RS232 et developpé mon propre VI d'aquisition.
A ce jour j'arrive à faire l'aquisition de toutes les valeurs mesurées par le multimetre quand celui ci est raccordé sur le port COM d'un ordinateur fixe.
Le multimetre FI2803 MT est doté d'un port USB et l'on me demande maintenant d'adapter ce VI pour que l'on puisse faire l'aquisition sur le port USB d'un ordinateur portable.
Le fournisseur du matériel m'assure qu'il s'agit simplement d'un adaptateur RS232/USB integré au multimetre et que donc les trames sont identiques.
J'ai donc essayé avec VISA driver Wizard de rendre ce materiel visible quand il est connecté en USB.
-Creer driver Visa
-VID:04B4     -PID:5500 (informations recoltées dans la gestion des peripherique de windows)
Je n'ai eu aucune erreur durant la procedure. Cepandant le materiel n'apparait pas sur mon VI dans: Nom de ressource VISA mais dans: Nom de ressource IVI... J'avoue ne pas tout comprendre.
Dans MAX -> Logiciel: NI-VISA -> alias, j'ai trouvé mon materiel sous la forme: USB0::0x04b4::0x5500::NIVISA-0::RAW    FI2803MT.
Me manque t'il un driver ou un logiciel pour simuler un port COM et le rediriger vers l'USB? ai-je fait une mauvais manipulation?
Ou bien faut il que je recommence la parti communication de mon VI en l'adaptant à l'USB si cela est possible?
En vous remerciant par avance.

Bonjour.
La situation actuel a légerement envoluée.
Apres avoir sélectionné la bonne classe VISA sur le Nom de ressource mon multimetre m'est enfin apparu.
Dans mon esprit cela allait etre aussi simple que sur le port COM car je n'ai absolument aucune information à envoyer, je n'ai que de la lecture à faire.
Apres plusieurs essais infructueux avec les bloc USB,  je me suis lancé dans une peche aux informations comme l'indique le fichier FI2803_USB_param.jpg joint.
J'ai également renouvelé *l'écoute de port* ce qui m'avait été bien utile avec le port COM. fichier Trame_USB.txt joint.
Vu que LABView est arrivé à lire ces informations sur le multimetre, je pense que mon cas n'est pas desespéré et qu'il manque peut etre juste un petit quelque chose mais je n'arrive pas a mettre le doigts dessu... Me manquerai-t il une donnée du probleme ou est ce que tout est là?

Ipod Nano/iTrip/Car charger problems.

I recently bought an itrip nano (the one that fits around your ipod) and i originally had a charger for my car, but thanks to the good people at apple I had to buy a new one because no cables would fit the old charger with the itrip plugin.
*end rant, begin question*
Alright, I ended up buying a macally car charger that had a USB port that would have a wire that could fit the two together (cost about 40 bucks). Ready to here nice clear music right? (clear enough since i did remove my antenna) Wrong...now I hear this annoying high pitched sound if i turn up my car speakers...I already know the problem with reception when you turn up the ipod volume...so what am I to do??
This isn't a question about reception, ive known for awhile the reception problems that come with these devices. This is a question of that freakin sound, and I'm sure someone is going to tell me that i need to buy something else. Thanks Ipod!

Either that or an expensive retrofit. My last car had a lousy radio so I bought a Sony that had an aux port. There are also some really expensive models that have iPod ports. Another option for some cars is an expensive device that adds an auxilliary input to your factory radio but there can be downsides. For me I have a choice of losing my XM radio or losing audible warnings. And then there's the FM transmitters. I bought a Kensington digital and am mostly happy with it. I say mostly because in some areas there is no free frequency so the iPod is unusable.

Can i communicate by the USB port, if my application is set up to communicate with the serial RS232 port???

Hi to all labview users... Please help me with my deadly problem. Last Deadline is on monday next week!.
I got a complete program now, written and tested OK. It communicates with a slave to control a motor. I've set up the program to communicate with the slave by the VISA RS232 Serial Port commuication. and all works fine...
Now the problem is.. that The communication should have been by the USB port instead. So what I have done now, is that i used a USB to RS232 converter. So that the USB Plug is plugged to the PC, and the RS232 end to my SLAVE,
When I send a command to my SLAVE, the SLAVE seems to understand it and it executes the command. But I must read some data at the port after sending my command to the SLAVE, coz, this command ask the SLAVE to start streaming data to me.
All communication to me from the Slave crashes so that i get ( sometimes if I get data ) wrong unknown data i cant understand.
So the big question is: Can i use USB communication although my Application is set up with serial communication if I use a USB to RS232 converter??? ( the Driver for the USB - SERIAL conv. is installed well.)
Baudrate :115200.. parity : none, Data bits: 8, stop bit : 1.
Please help me.....

Hi ZamZam,
Thanks for your detalied description of the problem. However I think the problem is how your USB-RS232 converter is converting the incoming serial command to the USB port. All Labview can see is a "normal" serial port. Do you have some information on the converter? You might also want to contact them to see if they are aware of this issue.
Thanks!

N80 reception

Hi got a N80 as upgrade to N70, love the phone but have poor reception in lower signal areas compared to other phones, N70 and 6680 can all be together, all on the same network, mine will not collect calls and drop outgoing calls when the others work fine, vodaphone swapped the handset but this has not changed anything, anybody else had this problem.
