Ready LED
After Power ON, Matrix 504 starts booting. Once system is boot up,
the Ready LED will show solid green. The Ready LED will be
turned off after Matrix 504 received
“
halt
”
command.
Link/Act LED
When Ethernet port are connected to the network, Link/Act will show
solid green and if there is traffic in the Ethernet, this LED will flash
Serial Port LED
These four 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.
Serial Port
The four serial ports can be configured as RS-232, RS-422 or RS-
485 by software. They use RJ45 connector and the pin
assignment are shown as following table.
Port 1: RS-232/422/485
RS-232: RXD,TXD,RTS,CTS,DSR,DTR,DCD,GND
RS-422: TXD+, TXD-,RXD+,RXD-,GND
RS-485: DATA+,DATA-,GND
Port 2/3/4:
RS-232: RXD,TXD,RTS,CTS,DSR,DTR,DCD,GND
RS-485: DATA+, DATA-, GND
Serial Console Port:
Serial console port is used for locally accessing Matrix 504
system using RS-232 port. The console port uses RJ45 connector
and is next to Ethernet port. Therefore please be careful to plug
in the right connector
Port 0: RS-232:RXD,TXD,GND
Therefore you need to prepare or purchase the serial console
cable (CB-RJ2CON-100) in order to use the serial console port .
In addition to the serial console signal, the console RJ45 port also
provides GPIO ( programmable I/O signal) function. The GPIO
port is CMOS I/O and can be programmed as digital input or
output. Power up setting is digital input mode with 75K ohm pull
up resistor.
Console
Power Connector
Connect the 9 to 48VDC power line to Matrix 504. If the
power is properly supply, the power LED will show a solid
green color.
Ethernet Port
The Ethernet Port use RJ45 connector
