3.2 LED Indicators
The LED provides the Matrix-752 operation information. The LED status is described
as follow:
 “Ready” (Ready LED indicator): Ready LED keeps ON when system is ready for
operating.
 “SERIAL 1” & “SERIAL 2” (Serial Port LED indicator): Dual color LEDs indicate
the data traffic at the serial ports. When RXD line is high then Green light is ON
and when TXD line is high, Yellow light is ON.

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
The pin assignment is shown as following table:
Port No. Pin1 Pin2 Pin3 Pin4 Pin5
Serial Port 1 RS-485 D+ D- -- -- GND
RS-232 (1) TX1 RX1 -- -- GND
Serial Port 2 RS-232 (2) -- -- TX2 RX2 GND
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:

To Enable RS-232 port, setting JP3 at Pin 1 and Pin 2
RS-485 (default)
RS-232
In the meantime, it should set D+/TX1 definition at JP6.
Default setting is for RS-485 (D+) at JP6/Pin 2 and Pin 3.

3.10 Serial Console Port
There is a 4-pin wafer box header (JP2) inside the Matrix-752 features as serial
console port that used for locally accessing Matrix-752 system via console port.
Pin assignment is: RX, TX, +3.3V, GND.
Therefore, you need to open the upper metal case and prepare or purchase a serial
console cable to use the serial console port.
Or, it can be purchased “Console Cable” from Artila, P/N is CB-P DF9-050.
