Barcode Scanner for very old system

Hi all.
This is my first post and first of all let me apologize for my english ...
I have a big (for me) problem with the scanner codes in HP3070 system:
In one of the testers HP3070 i have broken barcode scanner.
Tester does not have a PS / 2, (the old keyboard is connected to port HP-HIL) and the scanner was connected to the SCSI/RS-232 terminal .
My question is:
Is there a chance to connect an ordinary RS-232 scanner (with its own power supply) directly to a seu-4470 ( I have 4 free ports) , or the SCSI/rs-232 terminal (currently all ports free ) ? Is this possible?
I have a lot of handheld scanners with RS232 port (DB9 connector ). How to configure the software to work with them? How to do the right cable?
Please help because I recently began working with the hp3070 and I'm still a little green.
I would be very grateful for any help.
Regards.

To answer your question, it is possible to use both - you can maybe find older style HIL on ebay that allows keyboard in the loop.

if you need to add to unix SCSI expansion box, of course this is possible - you will probably need RJ45 to DB9 connector (as most barcode connector are RJ45) and you will need to assign the port inside the testplan.

below is an example of barcode readers assigned to UX port(the ones commented with a !) and also example assigned to PC (using /dev/com/X)

you will need to read the manual for assigning a label (like @BCR1 below) to a device file, /dev/ttym04 (which is the serial expansion port 4 )

so yes its possible - but you need to match DB9 to RJ45 cable to a barcode reader - also consider to buy a PC controller.........

!assign @Bcr1,Bcr_Error to "/dev/ttym04"
!assign @Bcr2,Bcr_Error to "/dev/ttym05"

assign @Bcr1,Bcr_Error to "/dev/com/7"!
assign @Bcr2,Bcr_Error to "/dev/com/8"!digi port 2

timeout @Bcr1, 3   ! time out after barcode read
timeout @Bcr2, 3   ! time out after barcode read

control @Bcr1,3;oti("4275")    !set up port
control @Bcr2,3;oti("4275")    !set up port

Hi,
Thanks for your reply.
I have a handheld scanner and rs-232/rj45 cable plugged into port 1 in the SCSI expansion box.

In the file /etc/inittab I removed the # for port 1 SCSI expansion box.
I rebooted the system.
I plugged everything and ... does not work.
I do not know what else to do.

The testplan file I have something like this:

Global @ Reader, True, False
assign @ Reader, Error is "/dev/ttym01"
Reader_OK = True
if Error then
     print "Could not assign HFS device for barcode reader."
     print "Use keyboard to manually enter serial number."
     Reader_OK = False
end if

Config_barcode:
then if Reader_OK
     control @ Reader, 1; oti ("10 244")                       ?????
     control @ Reader, 3; oti ("10 560")                       ?????
     control @ Reader, 4, 0                                         ?????
     control @ Reader, 10, 0                                        ?????
     control @ Reader, 11, 0                                        ?????
     control @ Reader, 16, 2                                        ?????
end if

What do I need to change (and why) to make it work?
Regards.

There could be many reasons why this is not working, in unix there are 2 methods of defining the serial ports, either using control sttamenet or using stty option line.

i have put example below how i had defined a RS232 port in the past, but i think you should look also in the manuals, regarding control statements and for RS232 - you should find some useful things there

you also have to be careful about plugging scsi items into the UX box - make sure it is always powered down

UX can cause a lot of problems, and some issues are easy fixable, other not so quick - whereabouts are you working?, I can try to get some additional support if you are in Europe

!***************set up the port using stty (unix) commands*********

Terminal$= "/dev/tty00"
Term_Set$= "stty cs7 istrip -ixon -ixoff parenb -cstopb -parodd "
Term_baud$ = "9600"
!*****************************************************************
print using "@"

!***************BT Basic port assignment *************************

assign @Term,Error to Terminal$;read,write

timeout @Term,2.5 !put a timeout on the port for response

!*********** execute unix command to initialise port***********

execute Term_Set$ & Term_baud$ & "<" & Terminal$ & "|"

!**************************************************************

Hi,
Thank you very much for the new instructions.
I'm already at home and I can not check but I'll try tomorrow morning.
I live in Poland. My boss is looking for two new controllers, but I want to run this scanner, because the purchase of new controllers may take some time.
I have some ideas:
- I'll try one more time to review the configuration files. Probably I have an some error in them.
- I'll try to check the port with the command "tail-f /dev/tty00" (if such is available in HP-UX).
I have some experience with Linux but I've never worked with HP-UX.
I will be grateful for any new suggestions.

Regards.

Hi,

Finally, the barcode scanner works. :)
I configured the serial ports taking inspiration from a little on:
http://pbraun.nethence.com/doc/sysutils ... erial.html
I plugged the scanner directly to the serial port on the controller.
I replaced in "testplan" /dev/bcr device to /dev/tty0p0.
The scanner came to life. :)
Oconnellj, thanks for the tips.
Regards.

What I am using now is this .NET QR Code barcode reader SDK . It's easy to read QR Code barcodes in .NET program. Share with you all. At the same time, you can also find many kinds of barcode generators on that site, such as ASP.NET QR Code barcode generator SDK ,

  If you wanna save these complicated steps and find a easy way, you can google barcode generator and you will find many useful tools, or google how to create barcode in c# to get instructive articles.i googled it for you , and i found a better tool which i think is very easy to use.this is the QR code generator which can be applied in c# and other formats. besides, this is the QR code reader which is easy to use .

Check this Barcode Scanners Integration Manual which might give you little bit hint of your own scanner issue. I'm using a Java barcode reader for different symbologies and it allows me to easily add barcode recognition functionarlity to Java projects
