I bought 5 pieces of W7500S2E-R1 module to test their use in my products. After the first installation of WIZVSP, everything was working properly for some time. With two of my devices with your modules I communicated correctly over two VSPs from my laptop. After that, both VSPs have disappeared from my laptop and I can not longer create them in WIZVSP. The following message is displayed:
Error occurs when add the connection
Couldn’t create a connection:your licence has expired.
I can not understand this message clearly, but it may be because I installed the WIZVSP on the client PC with the same key when demonstrating how new devices work. If so, please tell me if I need a single key for every client I am selling my equipment with the W7500S2E modules. How did I send the MAC address of the application registration module can I create multiple VSPs in a single WIZVSP.
I believe that you can answer me more easily if I describe my needs more clearly below:
I produce a series of devices that are parameterized and / or communicated through a serial interface (most commonly RS485) with a PC application. As today’s Ethernet network is used, I have to install serial to ethernet into my devices. So I have to be able to communicate with each of your purchased modules from a development PC, a service laptop, and of course from a PC at the end user. I’m not sure if this is covered by the accepted license, ie what I have to do so that your modules and WIZVSP driver for multiple ports might use it as described.
I’m asking for a quicker answer. Because i need to deliver 2 prototypes and now i do not communicate with the already produced devices.
