 Bigger Bigger  Smaller Smaller  Reset Reset


      I'm trying to connect two devices with my Ardunio Uno , the first device is a meter with RS485 interface .. the second device is SM5100B GSM modem.

      I'm new with those devices and with some researches i found that they are both use RX and TX pin (Is that right?) , in Arduino board there are 1 RX and 1 TX .. so how can i connect those two devices with the Arduino Board ?

     I just need headlines for how do i connect those devices to my board and which librarys is should use ?
     Also how can i communicate with both of them  ?
