raw data from barcode scanner
my experience with barcode scanners equals to absolute zero, so I am posting a very naive question :-). Is it possible to get raw image data from barcode scanner e.g. a line of b/w pixels (e.g. bytes or bits, whatever it is) ?

Re: USB barcode scanner?
They are LED or Laser. The difference is range and fragility. The LED ones have to be used much closer up to the code, like 6 inches, but they are very robust. The Laser ones can be used quite a distance away, but don't drop them. I prefer LED. They will get dropped. As others say, the 'wedge' ones act like a keyboard, and need no drivers. But, and it may not matter in your application, bear in mind that they send the characters they read followed by either return or enter but not both. This has a couple of consequences. If you allow keyboard entry of codes as well, obviously you have to handle both enter and return. Also I had some timing problems. I made caps D send mouseup to a Discount button. The user wanted for the cashier to be able to either do discounts by just using the reader, or alternatively, just using the mouse. Problem was that it sent mouseup to the Discount button and then sometimes but not always then sent return when the user was expected to first enter the amount of the discount I fixed this by the brute force method of sending to an invisible dummy button, waiting a fraction of a second, and then sending mouseup on, so absorbing the enter. Sarah's little stack was very useful in decoding what exactly the reader was sending. If you want to handle some keypresses, this means that you know exactly what is being sent and so you can harmonize the keyboard and the reader. kbarcode, if you can run Linux apps, is a great free package for generating bar codes and printing bar code labels. Bear in mind that if you generate labels in a word processor, like for a cash register laminated sheet, and there are quite a few free bar code fonts out there that can be used for this, you have to use start/stop characters, and these differ from Windows to Linux, and I assume the Mac will be different as well. Its * for Linux, and if I recall correctly its ! in Windows. You can find yourself staring at the thing in frustration wondering why the shop label codes work perfectly, but the ones you have just made up do not. This is probably why. I found the really hard issue to be not so much this stuff, as the tradeoffs you end up considering between convenience and security. Very hard to strike the balance. You have to spend some time thinking like a thief and craftily installing logs, and whatever you do you'll miss something. -- View this message in context: http://www.nabble.com/USB-barcode-scanner--tp20747555p20759008.html Sent from the Revolution - User mailing list archive at Nabble.com. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution
USB barcode scanner?
Hello! Can anybody recommend a usb barcode scanner that I can get to work with rev? I using rev 2.81 and a Mac.

Re: USB barcode scanner?
Timothy , Most of the bar code devices operate like a keyboard input device out of the box as a straight barcode scanner (i.e. outputs a translation of the barcode in text), others have features like storage where the scanner does not have to be tethered to the computer, can dump later, Wifi, etc. Most of them won't mention the Mac, even though everybody's conforming to standards. So don't let the PC part deter you, unless you need software to do more than recognize IPC symbols. It appears your scripts will do the rest. It's interesting in the peripherals world, when often many USB and Firewire devices built to standards, are sold with no reference to Macintosh at all in the ads and packaging, even though they work perfectly (and often install without drivers) and are a significant part of their sales are to mac customers. This is especially true of hard drives and network routers. Incredibly ignorant of the marketers if you ask me, and a wasted opportunity. I used to be an annoying Mac Evangelist (remember those?) when we felt we had to fight every fight against the PC 'hegemony', or we'd be stuck with the alternative in the future. Today, Apple's strong, hip, visionary, and makes solid products these days that sell themselves, so I don't have to do that anymore. I think Jacque was on the Evangelists list, or was it Mac Marines? It was a while ago. Over 20 years of mail-lists. The mind boggles. Hello! Can anybody recommend a usb barcode scanner that I can get to work with rev? I using rev 2.81 and a Mac.

I've got my POS app working nicely now and it's time for the next step...adding a scanner. What Stephen said. One other thing to know is that the barcode scanners can have their behavior modified by scanning barcodes in the booklet that comes with them. For example, you can have the scanner send a return after it's finished reading the barcode. That can be handy for your input routine, so it knows when the scanner has finished sending. There is no difference at all between a user typing on a keyboard, and the scanner sending its keystrokes, so if you have an application where a user is supposed to type into one field, and a scanner grabs a barcode without showing the text captured, your user could trigger the scanner while typing into the visible field, and they will see the barcode numbers typed in for them. That may not matter, but it could influence your design, you would want to make sure not to set up situations where the user can easily be confused. Another setting for the scanner is the baud rate (they're really serial, with USB converters). Set that to as high as you can, and even then the apparent typing speed is not very fast. ___ use-revolution mailing list use-revolution@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-revolution

Hi Tim: I haven't used it extensively but I have an IntelliScanner Mini from here: http://www.intelliscanner.com/ The biggest selling point for me on this unit is the size -- it could literally fit on a keyring. It works in 2 modes: batch, where you scan codes unplugged and it stores codes in onboard memory; and tethered, where scans are immediately sent to the front most application (or one of the applications that ships with the unit). It's been a while since I last used it, but I just installed the latest dashboard software on OSX 10.4.11, and ran it with Revolution 3. Scans are immediately transferred to an open field, along with a return character. FWIW.

Recently, [EMAIL PROTECTED] wrote: it sounds like the only drawback is: 1) A clunky cable interface Well, IMO, a scanner that has some kind of display on it would be the ideal. Because this unit has no display, there's no way to know how many items are on it or what you last scanned, but then again it's a relatively inexpensive unit. I forgot to ask - - - are you doing this on a Mac or Windows platform? Would this work with a Mac? Mac. How does the scanner know that the data actually made it into the computer before it deletes all it's contents? It doesn't care. It sends the text whether there's a field or not, the same as if you'd typed on your keyboard without being focused on a field. It works 2 ways: 1) without the cable connected, it stores scans and then dumps them when the cable is attached 2) with the cable connected, each scan is dumped immediately OK, enough [OT] for the list.

Here's the official word I got back from a representative: IntelliScanner mini is not designed for use with our business software (such as Inventory and the Business Integration Kit) or third-party applications. You'll probably be able to use your mini with keyboard emulation for your Revolution app, but third-party integration is unsupported with our consumer product line. I'm still trying to get details on how to possibly connect the scanner output to Rev but they clearly do not support any app development with the consumer model -- you need to go with one of their business products for that. As it stands, the connection from the scanner to the computer is a little klunky. You use two cables and a Keyspan adapter in between. Apparently, once you connect the scanner to the computer and the data has transferred, the scanner is automatically wiped clean for the next scans. I'm using the kitchen software, which connects to an (online?) database in an attempt to match your scanned codes to products in the database. It's pretty cool, but several of the products I scanned have incomplete info or do not appear in the database at all. Because of the form factor (much like a keyring flashlight) it is quite easy to scan items around the house and one can see how scanning could become addictive. Their motto: Scan responsibly.

Re: Any way to use BlueTooth Flic barcode scanner in Rev?
There are a lot of bar code scanners out there. Most will work substituting for a keyboard and with any software. USB seems to be the lingua franca these days, in which case it should just plug in to a USB port and will simply type a number into 'the selection' in a field after scanning. This will work with any app that allows input into fields. some wands can 'remember' and timestamp many scans and could be docked periodically for data download. serial port for interface might be found in older models. Rev can do this, either through a real port on a PC or a virtual port with a Keyspan USB-serial dongle. If the device is bundled with inventory software, beware of proprietary connections and platform incompatibilities. bluetooth might work if the drivers patch into the keyboard input, the computer in use has bluetooth, and all the compatibility issues are met. Wouldn't it be a lot easier to use a wire? You won't need anything else if you get a USB-as-keyboard unit. so choose wisely and talk to tech support before you buy. http://www.flicscanner.com/ I'd love to use this device with a Rev app I'm making if at all possible.

RE: barcode scanner
Many years ago I developed a system that collected data from a large number of barcode readers, as well as, other electronic systems. Most barcode readers then transmitted serially and could attach a prefix and postfix to the scan. We attached the individual readers to MUXs and the MUXs to a large serial switch (actually bank of serial switches). The serial switch had memory (most do). This then goes, of course, attachesto one serial port on the computer. So, depending on the nature of your app, you can then either let the reads accumulate in the switch and have your program poll the serial port when your application is ready, or set up your program to be interrupt or event driven by the serial port. Use the prefix and postfix feature of the barcode readers to parse your stream.

Then when that set of data is saved, a new blank page gets created and the cursor goes into the field for the bar code data, and the scan process starts over.

Re: barcode scanner
It might be, depending on the barcode scanner. However, it would likely require an external. My guess is that you would have to somehow use OS-specific routines to capture the barcode scanner device and deal with it more directly than by using the keyboard mechanism.

Is it possible? yes but the input has to be through something other than the normal keyboard interface. You'll need an alternate input stream and you'll need code to watch that input stream. The most common, but becoming obsolete quickly, is a serial interface. Then you have your app watch the serial interface and handle the data it receives. Beyond my abilities, I think Sarah has done much more work in this area. Kee Nethery ___ use-revolution mailing list [EMAIL PROTECTED] http://lists.runrev.com/mailman/listinfo/use-revolution
Re: barcode scanner
In many cases this is true. But think about the case where you are scanning identical items. It would nice to be able to type 10 and then scan the item instead of scanning each identical item. Suppose you want to route the item somewhere. You need to be able to enter the routing information. How about using a scanner to log in? You would probably want to type a password. If you just want to scan an item and then go to the next item and scan it, then not being able to tell where the input is from is fine. But in all the other cases you probably just want the scanned information going to a specific field (container) and it would be nice not to have to force the focus to that field with an addition mouseclick or tab(s) etc. Michael On Nov 27, 2004, at 10:48 AM, Frank D.

Re: barcode scanner
In that case it would likely depend on the scanner and on the interface between the scanner and the computer. In some cases this might not be possible to distinguish, in others it may depend on the configuration of the scanner, and in others it might require an external for Rev. Since the barcodes rarely use letters other than a possible 'X' (ISBN #s), one workaround might be to create a 'simulated' numeric keypad on the letter keys, then trap these and handle them specially for your purposes (with a keyDown handler); for example: Y=7 U=8 I=9 H=4 J=5 K=6 N=1 M=2 ,=1 space=0 Not a very elegant solution, but it could be made to work, and would rarely if ever interfere with a barcode scanner.

The problem, I envision, is when you integrate a keyboard with the scanner. How can you differentiate between keyboard input and the input from the scanner?
