Send data throught a cellular router

[jNuNeS-_- 0]

Hi.

I'm working on a project where I'm using 2 tm221ce24t PLC's and 2 Robustel R3000 routers.

I'm trying to send data from one plc to the other by these routers, using the serial port and RS-232.

At moment, I already did the ladder to send/receive the data but I'm stuck now.

The first PLC sends the data but the other doesn't receive.

I setup a transparente master/slave serial communication on the routers, but I think the problem is on these configurations.

I already did the cellular setup of the SIM cards to.

 

What is the best way to do this?

What AT command should I use to connect the TM221 to the robustel through the serial port?

I'm talking about the init command for the generic modem.

 

Thanks
