Hi, Mr. Gary & I did 2 way communication between FMD88-10 with GSM modem to send & receive SMS was successful done.
Currently i am trying out with Nano board , GSM modem and using Auto-RS485 between for comm port purpose. I am unable to establish communication. Mean while i did test out with ADAM 4520 (RS232-RS485 isolated converter) seem to work fine.
Is that possible to establish communication with Auto RS485?
Thank you.
