    DEX UCS with MC45

    Rodrigo Farfan

      Hi everyone. I'm developing an application for MC45 using DEX cable to connect to MEI CashFlow 8500 and to download EVA/DTS account information. The application is developed using .NET CF 3.5. The fact is that the reference implementation for DEX/UCS is in C++ for Borland C++ (yes, 16-bit exe for MS-DOS...). I've ported the code to C#, following EVA/DTS specification docs, and I'm getting some problems. In order to boost development I've developed a windows app that uses my DEX DLL (I've implemented it as a DLL) and using the MC45 DEX Cable connected to a USB on my laptop (via an microUSB to USB adapter and a Virtual COM port USB driver) the DLL works perfectly and I can connect with the coin manager (CF 8500) and download account information in EVA/DTS format. In the MC45 everything works fine until the coin manager starts to repeat the last data block. I've checked port capabilities and both (Windows and Windows Mobile) are equal (or pretty much similar).

       

      Has anyone experience with this? The most anoying thing is that DEX/UCS has a very much spreaded use for the last 2 decades, but no one has a library nor sample code in C# or Java.

       

      Thanks in advance for any answer.

          Hello. Finally I've solved the problem. My C# implementation was fine since the begining. The DLL reports its status via a listener interface and I was showing all the information in a textbox in a Windows Form. This is not a problem in the PC, which is higher in resources than the MC45, but in the device, showing all that information a keeping the user interface refreshed was adding the latency enough to do the coin manager timeout the DEX session. After getting down the verbosity level during DEX session, everything perfoms well right now and I have the DLL working perfectly.
