4.8 Serial port(s)
There are three lines for serial communication port (TXD, RXD and the GND). This port can have
RS232, TTL, or RS485 level translation. Default speed is 115200 bps for communication.
Normally RS232/RS485 levels are used for communication with the external MDT devices while
TTL level is required for communication with the computer devices. Any MDT device can send
data through device serial port to the backend server. They can also receive commands from
the server.
