Q1 - We like to connect the modem in the shown picture to test the data transmission (before we connect it to the power meter). we have connected as shown for data
2 to 3 , 3 to 2 and 5 to 5. Pls comment if there is any other connection or what we have done is sufficient.
Q2- Do we need additional external 12 VDC power supply to power up the module? (we bought PLC-UART-12V).
what is the max watt for the circuit board. basically we dont know what is the supply current.
Q3- We are using DC power line as the transmission media for data. Advise if we can use the same source of power supply for both external power supply and transmission.
