GSM Module + RS485 transceiver directly possible ?

(1/1)

andre123:
Hello,

I was wondering if someone could confirm if it is feasible to interface a GSM module for example SIM900, SIM900, Quectel's M95 or Neoway's N10 , maybe if we use the RS232 interface with HW the flow control pins RTS/DTR to the MAX485 or equivalent to talk to a master RS485 node ? or do i need to use a microcontroller to handle that ? What got me suspicious is i never saw an RS485 GSM modem without having its own microcontroller, that got me intrigued. 

Regards
Andre
