POS for .NET (title changed by admin)

[jvillaro]

Hello people, I've recently started to develop POS solutions with POS for Net.
I was wondering if some of you out there are doing the same and maybe we could help ourselves because I can't find to much info to more specific problems, just the easy little liinedisplay demos.

Has anybody ever used a Datalogic 8300/8400 scanner-scale?

Hello, this forum is very much alive! I would like to hear more about what you have in mind!

Hello Henny,

It's great to find a place to talk about POS systems.
I really don't know if some people here develop this kind of software or it's dedicated to users trying to find help with their systems and/or hardware.

In my case, as mentioned before, I'm developing a POS software for a client and found myself with a problem with a certain hardware. I'm new to POS so that could be it too
The client purchased the Datalogic Magellan 8300 Scale/Scanner, it seems to be a great product but for me it has been a pain in the... It's supposed to be easy to use and program but that has not been my case. I have downloaded the OPOS drivers from the dataogic website, it includes a test software that I've been able to use for the scanning functonality and later use in my POS. But ths scale part doesn't work you either get timeouts or "scale not ready" messages IN THEIR TEST SOFTWARE nad in my tests I get the same. I'm using .NET and POS For Net for my software.

Does anybody have a clue? Any help would be much appreciated.

Sorry to hear your troubles. If you are new to POS hardware, you will quickly find out how finiky the hardware and OPOS drivers are. Couple of quick questions. What is the interface for the scale and scanner? Are htey seperate interfaces?

[Henny]

Also, wat version of the drivers are you using?

Is this a true OPOS compatible system? What is the OS?

Hey guys thank you for helping out,

We are using/testing the following OS: Windows XP SP2 and SP3, Vista Business/Ultimate 32 and 64 bit and Windows 7 Ultimate RC1. We are using POS for .NET v1.12 wich should be compatible with OPOS 1.12 to my knowledge (limited ).
The service objects that are provided are current with the OPOS 1.12. This is the link for the info on the Service Object reference https://easeofaccess.scanning.datalogic.com/public/marketlit/Send.aspx?file=R44-2622A.
We are using the RS232 Single Cable Interface for both functions (SCRS232Scanner and SCRS232Scale) the scanner part works fine the problem is with the scale. The driver are the "OPOS Drivers v1.12.0046"

The thing that puzzles me more is that I canīt get the scale to work even with their test software, it could be a hardware/OS problem? I connect the scale to my laptop that i use for the development via a serial to usb cable... I thought this could be the problem but as I said the scanner works fine just as other POS hardware like the printer and Line Display.

This is the product link http://www.scanning.datalogic.com/sitefiles/mg8300.aspx

OK, couple of questions, is appears from the specifications that the scanner uses USB and the scale uses RS232 (serial)

Is this correct?

If so, changing your bios settings will probably fix this. Give your serial ports an unused IRQ and enable bi-directional communication.

Hope this helps, if I had one of those units on hand it would help, but I do not...

Hi Henny, actually the device supports both functions on the same serial cable. They call the interface RS232 Single Cable. When you install the drivers you get to choose from 4 types of interfaces. You configure a settings xml file to indicate ports and other and other stuff.

I know it's really dificult to know when you don't have the device yourself, so I really appreciate the effort your making to help out.

[Henny]

OK, so have you changed your BIOS settings for your onboard serial port?
