Serial Devices and Modems

I need to control a remote instrument via RS-232 via a modem. Does anybody
know of any VI's that will allow me to dial through a modem to another modem
connected to the RS-232 device (a digital pressure gauge in this case).
Thanks.

Serial port and modem

Hi,
I want to know whether a modem is connected to any of the serial ports in my system. Is there any way I can detect the presence of a modem connected to my desktop?
Thanks in advance,

Basically, it is not well-written from both a LabVIEW and a communications point of view. Unfortunately, I can't elaborate because today is an exrtremely busy day at work. I'm hoping this bump will prompt someone to help you with your problem. If you could also provide us with the programmer's guide or the manual for your equipment, that would be extremely helpful.

USB/Serial Drivers and App Builder Installer Questions...are drivers included in the Installer with the LV runtime engine?

Hello all,
I'm wondering if someone can help me out with how drivers and all are treated with applications distributed with App Builder, used to create a stand alone, full install of app and labview engine with Installer.
What has happened is, my application was created using the NI branded USB to RS232...and USB to RS485, and they work great.
On the application when running..you fire it up, it finds the USB to serial device, and I have a dropdown that finds the available COM ports to use (along with setting parity, etc).
I've installed on different computers (without previous labview installs) with the installer. They all worked.
The customer has received the installer....and despite us telling them to use the NI branded USB/Serial interfaces..they are trying to work with a different USB/serial cable.
They say the COM ports aren't even showing up when they run the installed application.
So, I'm not sure where to start. Is this a driver issue? Does the App Builder Installer...install the drivers for the interfaces I was using with it? Is there a way for the person to find and install a driver on their own...or would I have to somehow find out a driver for what they use....then, basically redo the App Builder Installer build...to include that driver with the executable I send back out?
I guess I basically need a better understanding of how drivers for external access/communications are handled when you use App Builder to create a stand alone application complete with the labview runtime engine...and nothing else.
Thank you in advance,
cayenne

The main thing is that LV uses VISA to talk to serial port whether native on the machine or from USB dongles that you plug into the computer. It sounds to me like their dongles aren't working.
Can the customer see the ports in the Windows Device Manager? Can they access them through something like hyperterminal? How does your program find the USB/Serial devices?

Does anyone know how to intergrate all three of these items together? Basically which plug goes where. Currently my phone is not working. The only thing that is in use right now is my linksys cable modem. I have the power cord plugged in, the blue cord from the modem plugged into my laptop, and the cable from the modem to the wall jack. Please help. Thank-You!

It is possible to know my UDID only with the serial number of my device and without the device?

Hello, I would want to know if is possible to know my UDID only with the serial number of my old device and without the device. I sent my old device there was a few months and they can't repare it, so they pay me back with a voucher and I bought a new one (iPod Touch 4g 8GO). I have to know the UDID of my old device to transfer all of my game to my new device (all the data for not to start all the games again) BUT I just had only the serial number.
Someone can help me please? Thanks

Interfacing of RS232 serial devices through USB ports within LabVIEW 6.1 and Windows 2000 Pro?

I have a data acqusition requirement of using 5 RS232 devices, but the motherboard i use only has two serial ports. However, it does have 4 USB ports. Does anyone know if it is possible to use these USB ports to input data from an RS232 device through a serial to USB converter?
Does LabVIEW 6.1 support this under Windows 2000 Pro?
Thanks in advance,
Fraser

Hi Fraser,
I just moved an app to a new laptop and had to use a USB to serial comm adapter. At first try the app did not find the comm port.
After sleeping on it, we downlaoded the most up-to-date driver for the device and upgraded VISA to the latest and gretest version.
Everything worked fine after that.

USB Serial Devices - Description and Information

Hello folks, I am trying to detect which kind of USB/Serial device is connected through Labview: through the VISA Find Resources i can list all the GPIB/ASRL devices connected and then through the Interfice Type i can detect the Serial/USB devices (interface number 4) and through the Interface Description I can get the name (COM7 for example).
Now my point is that if i look on the "Device Manager" in Windows i can see the "Manufacturer Name" and the "Device Description from BUS" of the Serial Device connected. Is there a way to get those information inside Labview?
Thanks in advance and best regards

Hello Dario,
the best option might be to use DevCon, a commandline based device manager from Microsoft.
Windows Device Console (Devcon.exe) (Windows Drivers)

Connection with serial device (SPP)

I try to connect with a bluetooth serial device (a robot, no standard device) which is working with every PC but not from my MAC. I can connect to the device (I use ZTerm) and send one character, but not more. If I send more, those characters are not send until I quit and restart ZTerm. Then (nearly) all characters are sent. I can get all characters sent by the device. It seems a problem of flushing the buffers at some level of the drivers. Any experience or idea?

Hi!, Ranothil: If you have the next cable and "null modem" (http://commerce.hpcalc.org/serialcable.php), you can transfer, anydata, from HP50G, to PC and viceversa, across Connectivity Kit (Conn4x), without problem. Please, see this link, with instruction's, for transfer data with serial cable, null modem and connectivity kit ... http://sense.net/~egan/skb/ and/or ... http://www.hpmuseum.org/cgi-sys/cgiwrap/hpmuseum/archv017.cgi?read=125259 Note: Better, if you transfer data, from HP50G to, PC and viceversa, across the microUSB.

USB to (DB9) Serial Adapter and Minicom - help needed

I'm having problems with my Netgear DM111P ethernet modem.
I bought it off ebay and it was 'bricked' on arrival .
All of the LEDs are flashing okay except for a solid red one which should be solid green.
I would like to reflash the firmware. However, I've never done this before and I'm learning as I go.
I've only just started the process and so far it hasn't been that successful.
Basically, I don't know what to do.
Since my IBM Thinkpad T40 doesn't have a serial port, I bought a USB to Serial adapter.
When I plug it into a spare USB port, dmesg reports:
usb 2-2: new full speed USB device using uhci_hcd and address 2
usb 2-2: configuration #1 chosen from 1 choice
usbcore: registered new interface driver usbserial
drivers/usb/serial/usb-serial.c: USB Serial support registered for generic
usbcore: registered new interface driver usbserial_generic
drivers/usb/serial/usb-serial.c: USB Serial Driver core
drivers/usb/serial/usb-serial.c: USB Serial support registered for pl2303
pl2303 2-2:1.0: pl2303 converter detected
usb 2-2: pl2303 converter now attached to ttyUSB0
usbcore: registered new interface driver pl2303
drivers/usb/serial/pl2303.c: Prolific PL2303 USB to serial adaptor driver
and lsmod shows the pl2303 kernel module has loaded:
n00b ~ $ lsmod
Module Size Used by
pl2303 19076 0
usbserial 30696 1 pl2303
So, if I understand things correctly, the USB to Serial adapter has been recognised by the kernel and the driver loaded. dmesg also reports:
n00b ~ $ dmesg | grep tty
console [tty0] enabled
00:0a: ttyS0 at I/O 0x3f8 (irq = 4) is a NS16550A
usb 2-2: pl2303 converter now attached to ttyUSB0
which suggests I should configure minicom (# minicom -s) with /dev/ttyUSB0 rather than /dev/ttyS0. However - and this is where I'm out of my depth with minicom - when I invoke minicom it comes up with a dialog saying "Initializing Modem". I don't want to use a modem. I want to see what the CFE bootloader of my DM111P is outputing so that I can see what's wrong with it.
Can anyone help me out with this please? I've never done any serial port work before.

Thanks for the reply Rasika but I already tried that cable. Checked it out with an Ohm meter, cable was pinned correctly. It worked on a 4402 controller but not the 2006. I did try all kinds of serial settings and usually you get some garbage displayed if the baud rate, parity, stop bits, etc... are wrong but this had nothing displayed. I suppose it's possible that both 2006 controllers are bad but the odds are extremely small hence I still suspect the cable. Do you know of an actual Cisco document that shows the console cable pin-out for the 2006? If I had an actual Cisco document and not a user supplied document and that cable didn't work, then I guess there recycling material. Any other idea's or thoughts? Thanks!

How to restore deleted playlists to an itouch after syncing with wrong device. Tried to search for device to restore under devices and it completely removed it as a device on itunes. Is there anyway to get the information back?

To start we have several users and devices on our itunes account....Several weeks ago I was using my itouch to create playlists for a few aerobics classes that I teach. Right before I was about to unplug the itouch I got a notification that my itouch was full and didnt have any space left. Since I was done with what I was doing at the time, I unplug my itouch and figured I would delete unwanted songs later to create more room. A week later, I went to sync my itouch into itunes and over the devices it told me that it was named another device and wanted to know if i wanted to sync the information to my itouch I had just plug in. I had never seen this message before in all the other times I had used it, and at the time I didnt realize that it was giving my device the name of another user in my house. Without realizing it itunes started to sync the new information to my itouch. I immediately unplugged the usb cable stopping the process. I then replugged the usb cable in, hoping to get done what I needed to get done on my itouch thinking it might have just been a strange glitch. Also, since I hadn't notice any change on my itouch from the incorrect syncing, I continued to start itunes again. This time it asked me the same question as before "did I want to sync the information from another ipod?". Since I didnt notice any changes before I just let it do the syncing not realizing at the time that it was earsing all the info I had on my itouch and replacing it with info coming from the other users ipod.
I contacted Apple and they gave me infomation on how I could go look for my itouch under devices and get the information back. When I did this my itouch was no longer there under the devices and it was replaced with the new name that itunes had given my itouch. This device is one of the first generation itouches and has never been backed up that I know of... So my question to you all is...Is there any way of getting my playlists back???? I spend countless hours creating these playlists for my classes and have been completely out of my mind trying to figure out how I can possibly get the infomation back. Please let me know if you think there might be a way to do this!!!

The devices that are listed are: 2 under the name of the device that synced incorrectly with mine and then 3 others that are not associated with my itouch. The name of the ipod, before the incorrect sycning is no longer under devices. It has been replaced with the incorrect one because I can see the serial # of my ipod under the wrong name.
The playlists that are in my itunes library are from an ipod that I used a few times before I took this one over... Which happens to be the ipod that took on the ID of my itouch.
Both of these ipods used to be my kids.. I used my sons a few times and then switched to my daughters. They each had their names attachted to their particular devices and now it just says my sons, which is the ipod that itunes was connecting to when all this happened. The really strange thing is my son doesnt use his ipod any longer and now uses his phone for music...So, it had been a while since that particular device was even synced to itunes!
I hope this helps!

My iPhone serial number and IMEI is not the same as Apple server

Hello,
My problem started when I want to unlock my iphone 3gs via Imei.
My old iphone broke about a month after i bought it (it was 2 years ago), so i sent it to Movistar to change it (i think that they sent it to appleCare). Now Movistar told me that i have to send the old iphone imei in order to unlock the iphone i have now, i ask apple for the repair order receipt, then i received an email and i could see the information about the 2 iphones: the old broken one and the new one.
Then I realized that the iphone they sent me as a replacement (the new one) is not the same iphone i have. The serial number and the Imei are different, so, should apple change this data in their server in order to unlock my iphone or what can i do to solve it?
There is any formal way to perform this data change?
Thank you in advance,
Francisco Marzabal

Here we work with repairs for devices that does not have waranty (expired or other issue). In this case, I did the screen replacement. No other ipad was on my station, the ipad arrives, i took it change the glass, put everithing back, give to customer. Thats it. The job was done by me, the customer test his ipad in front on me, works fine, everything ok. Few days pass and he came back saying that it wasn't his ipad, he brings the box that the ipad came and ask me why the serial number does not match the serial number in the box (sorry NOT in the back of the ipad).
There were no other part changed only glass. After 7 years working on this, thats the first customer complaining about a work done here. After this I was curious and look for more information and some forums, also one port here is claiming that the serial number on the device is not the same as the box where it came.
I just want to make sure that there are possibilities that there could be such mistake during the packaging process.
Thanks for the replies

Lately my finder closes when I select a shared devices and I can no longer connect to other macs. Wifi working, TC okay except in finder. Mac Pro running 10.8.5

Lately my finder has been closing when I select a shared device such as another mac, a printer, or the time capsule. My WiFi connection is working - I can can still backup to the TC and use my wireless printer, but I just can't access them by clicking on them in the finder window. Any suggestions would be appreciated!

Thanks for your help
I made no changes to the mini or the server.
The router was shut down then on restart the new (replaced modem) was configured by using another mac on the network (not the file server)
Once the router and modem were online again, other macs running 9.2 were accessing the file server as usual. The mini was not.
I had been working on a file that resides on the server. I was not warned that the router was going to be shut down. When I saved the file I got the beach ball then error message.
It'll be next week before I'm in the office agin. I'll report back then. Thanks

The service provided by the Samsung SCH-LC11 Mi-Fi device, and/or the 4G LTE service, is unusable.

I got the Samsung SCH-LC11 Mi-Fi device and 4G LTE service from Verizon about one week ago here in the Chicago area.
(Note: the first thing I did was update to the latest firmware (EF07) per the Samsung website.)
I am using it with my AT&T iPhone 4 with "Cellular Data" on the phone turned off completely.
I ran all the speed tests, 10 megabit up/down, wow, great.
Unfortunately, there are at least two major problems with it:
1) I noticed almost immediately that push emails stopped coming to my iPhone after a few minutes.
After looking into this in more detail I realized the following:
   a) The modem inside the Mi-Fi device is being assigned a 10-Net / "carrier-grade NAT" IP address, not a real Internet IP address. Fine, I don't really care as long as it works. I am not trying to use a VPN, or do VoIP, or run some webcam somewhere. In other words I'm not a "revenue leak" in Verizon "parlance" (I worked at Motorola during the OBEX fiasco days), but it's nice to know I'm being treated as such right off the bat.
   b) The "carrier grade NAT" appears to have a TCP timeout of no more than two minutes. I verified this by opening a telnet session to somewhere and not typing something for two minutes. After the two minutes I typed another character, but it never got echoed back and the connection was dropped. After waiting only a minute and a half, it lagged a little but sprang back to life.
   c) Problem is, push email relies on having an open TCP connection that is idle the vast majority of time. When an email comes in, the Exchange ActiveSync server sends a message back out to the device (over the existing connection) saying the mailbox has changed. Unfortunately, after two minutes of idle, the "carrier grade NAT" has dropped the translation entry a long time ago, so the connection is dead.
So I emailed support about this. (the ticket is "WFM87599752").
In the first round they told me to go look in the device's settings @ http://192.168.1.1. Yeah, did that already.
In round two, they blamed the dormancy timer. That's obviously not it, since the modem is layer two and knows nothing about TCP at all. Just to be sure though, I performed the test again, but this time I had a DOS window pinging Yahoo repeatedly so the modem wouldn't become dormant. Problem still happened. I saved the Wireshark PCAP here so anyone can see: http://home.comcast.net/~abcbwtxyz/two_minutes.pcap Frame #339 is where I try to type again, never to hear back.
2) The other problem is that as soon as a second person connects to the Mi-fi device over Wi-fi, the first person gets dropped almost immediately, and can't even reconnect again afterward. I mean, really? Made this video to illustrate: http://www.youtube.com/watch?v=Iadz4DGXFRM
So, can someone help? I know I'm not the only one having these problems; I sent the support alias the following links just as examples, there are many more:
http://himself.wordpress.com/2011/04/30/verizon-wireless-issuing-private-ip-addresses-to-3g-customers-class-a-nat-joy-and-gross-ineptitude-verizon-wireless-3g-fraudulent-enticement/
http://www.broadbandreports.com/forum/remark,26067018
http://www.droidforums.net/forum/droid-x-tech-support/101185-droid-x-verizon-3g-assigning-10-nat-ips.html
-Chris

So just to follow up on this. I called to cancel today. The CSR wanted me to talk to tech support about my problems and talk me out of cancelling so I said fine. Summary of conversation:
1) Immediate acknowledgment that the two minute timeout of idle connections is by design, and no dispute that it breaks push email.
2) Disagreement with the claim that a second person logging on kicks off the first, even though I offered proof. Dismissed my point that other people have seen the same exact thing, saying that if you look up problems other people are having on the Internet, people say anything and everything.
Anyway, I continued with the cancellation; to their credit, they waived the activation fee and credited me for "time served", so I won't owe anything. I did appreciate that.
