TCP/IP communication to a 3rd party Hardware module

[Ather.Iq]

I want to communicate to a hardware module which is connected through LAN as well as can be connected as a Wi-Fi device. This 3rd party module(Hi-Link's RM04) converts the data received through TCP/IP protocol to RS232. Its a protocol changer module. I have simply created an Applicaton to Write a character and the module which is connected through LAN must convert that data to put it on the RS232 serial connector.

I am getting an error while running the application. The data is not transmitted to the device.

Can anyone help me out in this.

Regards,

Ather

Hi,

       Could tell in detail what type of an error. I mean the error code.

[Ather.Iq]

Its Error code 66.

I also want to know that its necessary to use both the TCP/IP client and server side VI's ?? 

The application for which I am doing is I just want to make a single LV application client side which sends data to the module and it's received on the TCP/IP socket, I mean i know the IP address and port no. of the device.

Kindly guide me.

Thanks

Hi,

      The problem is that, the device is not listening. I think you should start the server side first and then the client also make sure the u have enough time for listening on server side.

Hi,

The thing is that the server is a module it has no LV application running on it, the only thing i had is the client VI running on my PC which is used to connect through LAN or Wi-Fi and communicate whatever I am writing it in the Write.VI but the things are not working my way.

Kindly reply and help me out of the problem.

I am creating an application on the PC which send commands to the module which is connected through LAN or Wi-Fi, but the module is not listening any thing.

Hi,

       I think there's some problem with the ports, if ports are not configured properly then this kind off communication happens. Check the ports. Do u have written any code for server? if so, which language is it?

[Ather.Iq]

The port number is correct.

No i dont have written any code for the server side.
