Communication Logs

connection_log.pdf

This is an export of Wireshark Logging from all communication with the terminal. The first entries until including time 5.111288 are made using the ZVT Library, the ones afterwards are from a successful connection using the official management tool CRS. Default Port for unencrypted communication is 22000, with SSL its 22001. I've used 22000.

More information

I cannot get a successful connection to my cash terminal, but I've tested it successfully with other tools like EasyZVT. I'd like to start my own implementation into my application, so this library seems like a very good fit. I'm not quite sure why the connection won't work. Default character set of this terminal is ISO-8859-1. Please let me know if you need any more information to help fix this issue.

Have they tested it with our ControlPanel?

truejp commented 2 years ago

It was tested with both the ControlPanel and the smaller version (just for amount) as well as the library itself. Thanks Philipp

In the ControlPanel is a Communication Tab. Can you take a screenshot after send the Registration?

truejp commented 2 years ago

I can't even connect to the device, the logs from my previous post were the unsuccessful attempt of connecting. The interface states "try connect [terminal ip adress]", then it states "cannot connect". All other buttons of course give back error "ZVT Client not ready" on the right hand side. Communication Tab has no contents. The logfile of the ControlPanel states "12:30:12.509 INF Portalum.Zvt.TcpNetworkDeviceCommunication ConnectAsync" all over again, just the time is adjusted.

The Log of easyPay gives more details:

same with port 22000? I think the port 20001 is not open on your device...

truejp commented 2 years ago

Yes, I've tried them both, none of them are working. 20001 is for SSL, that's right.

00:36:54.145 INF Portalum.Zvt.EasyPay.App App - Start 00:36:54.274 INF Portalum.Zvt.EasyPay.App RunOptions - Startup successful, start payment process wiht an amount of 0,01 00:36:54.440 INF Portalum.Zvt.EasyPay.MainWindow StartPaymentAsync - Start 00:36:54.715 INF Portalum.Zvt.TcpNetworkDeviceCommunication ConnectAsync 00:36:59.786 ERR Portalum.Zvt.EasyPay.MainWindow StartPaymentAsync - Cannot connect to 192.168.0.142:20000 00:36:59.798 INF Portalum.Zvt.EasyPay.App Application_Exit - Exit

This issue looks pretty odd to me since the initial communication logs look pretty similar. I thought about it maybe being an issue related to the "listening" Port on the PC running the Software, since this differs. I've not hat the time rerouting the ports yet, I'll maybe try this later too.

Default Port for unencrypted communication is 22000, with SSL its 22001. I've used 22000.

you have write 22000 is the default and not 20000
