The MG90 has a built-in DB-9 serial port on the rear panel. This port can be used by a computer to access the MG90’s Linux console, or can be used to connect an external device (application) such as a serial modem or external GPS device.
To receive data via the serial port:
Set the Serial Port to Application in Devices > Serial.
Connect a null modem cable with a DB9 connector to the gateway and the terminal.
Change the communication parameters below to match the terminal communication specification.
In example below MG90 is sending GPS data to Putty on a Laptop connected via Serial Connection.
Enable Serial Connection under GPS tab on MG90 and set Speed, DataBits, Parity, StopBitX2 and HW Flow as required. These settings need to match on the device that is receiving Data e.g COM 6 Port on Laptop in this case.
Now open Putty session to COM6 using Serial Connection type and GPS data will be send to Putty session.
In customer scenario’s the Application customer is using needs to be configured instead of Putty.
