Bidirectional coms with barcode scanner

Hey everyone. I'm trying to think big thoughts today.
I have implemented a CVI 2012 app that used a Symbol / Motorola LI4278 barcode scanner. Works well. For that application, I went next-to-simplest method by pre-formatting the scanners into CDC driver mode to work with Win7 as virtual com ports. Pretty simple then in CVI with a custom serial callback.
So onto my "big idea" question. It would be great to send warning beeps and LED blinks back to the user weilding the scanner. Mot has an SDK that I've stared at, but it appears to be C++ only. I'm not about to get in there and attempt a wrapper for it.
I found this discussion here, and it sounds relevant, but I'm not sure where they got their device library. So anyway, any thoughts on this?

Hi ElectroLund,
For the forum thread you linked in your previous post, he said the scanner in question came with a DLL. Since it seems your device did not come with a DLL and only a C++ library, it seems options are pretty limited. You could use a third party C++ development environment and create a DLL out of the C++ source code. This DLL could then be called within your C code.
Unfortunately, since this is regarding communication with a third party device, National Instruments does not support the actual communication with the device. We can assist with calling DLLs and supported drivers. I would suggest contacting the maker of the barcode scanner to see if they have any DLLs or C source code to be used with their devices.

How can labview communicate with barcode scanner of USB interface

I have no idea that USB barcode scanner is within USBTMC or not
and there is no information available from the BCR supplier about the communication.
Is there anyone give me suggestions?

All that you need to read the scanner is a string control - just like you were entering the code from the keyboard. Could not get any simpler.

Can I use a barcode scanner with LR?

Hello -
I am taking some school photographs and need to change the file name of each image to the registration number of the pupil. Is there a way of using a barcode scanner with LR to scan the code of the pupil's reg no and then automatically change the filename?
I saw a thread here http://forums.adobe.com/thread/799772 - but couldn't find the fields etc referred to.
While I'm here - can I download LR 4 SDK as part of Creative Cloud subscription?
Many thanks

I beleive you can download the SDK here: http://www.adobe.com/devnet/photoshoplightroom/sdk/eula_lr4.html The link is at the ens after the EULA

Contact your inventory app vendor. There are a number of such things, but generally the vendor of the hardware has a specific inventory app for it.

What kind of BarCODE scanner works well with LabVIEW ?

Currently I am working on a project need the use of Barcode Scanner to scan BarCODE. In our project, the minimum range requirement would be 30 feet. I noticed some posts here indicate there are some problems for barcode scan applications in LV to some specific Barcode scanner models. .
So, I would like to know if someone has successful experience for wireless or usb barcode scanner programming using LV, and the Barcode scanner model.
I would prefer wireless Barcode scanner.
Thanks in advance.

Hey Michenglaoxu,
I thinkt he best thing to do is look at a similar thread where someone was just looking for tips on where to get started and someone actually recommends a product. I can't guarantee the validity of his suggestion, but I thought you may find that link useful.
Good luck!

HT4509 Barcode scanner app with international keyboard

Hi,
is there any barcode scanner app that can be used as an iternational keyboard:
it should allow to be added from settings
when this keyboard is selected, the camera should open, allowing to scan barcode, and using it in any app, as normal keyboard?
thx

barcode scanner is an electronic device for reading printed barcodes. Like a flatbed scanner, it consists of a light source, a lens and a light sensor translating optical impulses into electrical ones. Nearly all barcode readers contain decoder circuitry analyzing the barcode's image data

Ingenico has a 1D Bluetooth barcode scanner certified MFi by Apple.
http://baracoda.ingenico.com/Baracoda-i-fly.aspx
Baracoda i-Fly is compatible with Apple iPod touch, iPhone and iPad.
Baracoda i-Fly supports IAP Bluetooth profile and is MFi certified, which means it is 100% compatible with Apple development standards and performances.
Its Bluetooth connection is bidirectional, which enables the i-Fly to transmit data both ways in mode « No Data Loss »).
Furthermore, Firmware update is also possible, which is not the case for non-MFi certified devices.

How would I create an USB Barcode Scanner Listener using Adobe AIR?

I want to create a USB barcode scanner listener that would read in the scanned barcode, and place the barcode in a field in my AIR App even if the program wasn't focused on that particular field in the App. If the client was using the application at the time for something else the scan would be buffered in AIR till requested or the AIR App has been idle for x period of time where upon the field would be brought into focus.
How would I go about this (I'm developing on windows) Was hoping for a USB solution within AIR but not fussy at all if I have to go outside AIR to solve this problem. Java, Flex, ActionScript, Flash, C, C++, C#, VB (currently I've developed the rest of the App using Adobe AIR and JavaScript)
I thought after some research that I could make a Java App (if all else fails) that listens and buffers the input and passes it along using a socket but JUSB doesn't work on Windows properly.
I'm not stuck on any one particular implementation or idea just want to get development underway so... Any ideas? or suggestions would be awesome. I've googled a lot but haven't found any examples or solid suggestions, so any URL pointing to that information would be great too, if you know of a good one, then I'd be able to read up on any suggestion.
Thanks,
Marty

Thanks Joe,
Just for anyone else. I bought a Metologic Scanner - VoyagerCG. I was trying to get it to work using Java USB for a bit with no luck. But if you get this scanner or one like it, it can be configured as a Virtual COM Port. Which is very very easy in Java to set up as a listener and use sockets to transfer the data and listen within AIR.
This PDF has links to drivers and instructions if this is useful to anyone.

I am trying to use a fixed Miniscan Ms4404 barcode scanner.

I am trying to use a fixed Miniscan Ms4404 barcode
scanner. In such a way that when a part passes through, it will scan
automatically without manually triggering the barcode scanner. Moreover is
there a way to use this scanner communicate with Slc5/03 Processor?.. basically
to cut it short i need a basic idea on how to setup this entire project. Your
input and suggestions will be greatfully appreciated.
Thanks

Do you have a means of detecting when the part is in position to be scanned, such as a proximity switch, or a camera, or some sort of load sensor? When you say the part passes through are you saying the part is continually in motion? How fast is it? If it's too fast you may not be able to detect the part being in position and triggering the scanner under software-based control.
as for the question regarding communicating with the Slc5/03 processor, this is a vague question. What's the processor doing? What kind of communication are you referring to? If you have a processor in there, what is the LabVIEW-based app doing?

The project is on the design stage, but the idea is to test for pressure decay in Automotive parts. Here is a scenario.
1. All the parts to be tested are barcoded for identification.
2. The testing station has a plate that moves in and out to load and unload the parts to be tested. And by the testing table, a Miniscan MS4404 is fixed to read off the barcode.
3. There will be two proximity switches that detects the part present.
4. As soon as the part is present it should stay for the entire test which should last for about 10sec at least. Simultaneously the scanner should be triggered.
5. Now since I am goin to use the MS4404 miniscan, my reseach tells me this miniscan and does not have trigger button, but I understand somewhere out there it can be triggered automatically,Software based, as soon as the part
is within its range. So that I will be able to communicates with scanner to enable. disable, beep, etc.
6. I need a way to decode the scanned data and store it my data base for passed and failed tests. i guesse this where the PLC and LAbView come into picture.
If there is a way to bypass PLC and cheaper way, I will welcome all the suggestions.
Thank you
Joe
