3.6 Serial Port 

The Matrix-752 has two serial ports:   

 

One RS-485/RS-232 ports, Default setting is RS-485. 

 

One RS-232 port (TX/RX) 

RS-485 is designed without isolation that automatically direction controlled via 

software

Enable/Disable Termination resistor for RS-485 (JP4) 

The Matrix-752 provides on-board 120Ohm termination resistor for each RS-485 

port. To enable the termination resistor, please remove the upper cover of the Matrix-

752, and the adjust the associated jumper to short as below:
