Power LED (PWR)
Power LED will keep solid green when power is applied.
Ready LED (RDY)
After Power ON, M-508 will decompress the kernel and root file
system to RAMDISK. Once system is boot up, the Ready LED will
show solid green. The Ready LED will be turned off after M-508
received “halt” command.
Link/Act (LAN)
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 (LD3~LD6)
These four dual color LEDs indicate the data traffic at the serial ports.
When RXD line is high then Orange light is ON and when TXD line
is high, Green light is ON.
Debug LED (LD1~2)
The debug LEDs are located near LAN LED and are used for system
boot debug. If system are correctly boot, they are switch off.
Serial Port
The serial port pin assignment is shown as follow:
Port 1/3: RS-232/422 (software selection)
RS-232:
RXD,TXD,RTS,CTS,GND
RS-422: TXD+, TXD-,RXD+,RXD-,GND
Port 2: RS-232/422 (software selection)
RS-232:
RXD,TXD,RTS,CTS,DSR,DTR,DCD,GND
RS-422: TXD+, TXD-,RXD+,RXD-,GND
Port 4: RS-232/422/485 (software selection)
RS-232:
RXD,TXD,RTS,CTS,GND
RS-422: TXD+, TXD-,RXD+,RXD-,GND
RS-485: Data+, Data-, GND
Serial Console Port:
Serial console port is used for accessing M-508 using RS-232. At
factory, serial console port is disabled because serial console port
shares the Port 3 connector with the pin definition as shown:
User need to prepare or order a serial console cable
(CB-F9F9-100) and enable the serial console port as described in
Enable Serial Console port
section.
Power Connector
Connect the
+5VDC
power line to M-508. If the power is
properly supply, the power LED will show a solid green color.
Please check the power voltage
and polarity before connecting it
Ethernet Port
The Ethernet Port uses RJ45 connector
SD Socket
The SD socket is compatible with SD memory card
specification version 1.0. The SD Socket is located in the back
panel of the PCB.
USB Port
The USB port is a USB2.0 high speed host port. It can be used
to expand the hardware function of M-508 and exchange file
and data between PC. Currently the hardware support by M-
508 USB is shown as follow:
1. USB
Storage
Device
2.
USB to Wireless LAN Adaptor (Ralink RT2571)
3.
USB to Modem (CDC compliant)
4.
USB Camera
Contact Artila if you find your hardware is not shown on the
list.
Reset Button
Press the “Reset” button to activate the hardware reset. Please
always use “reboot” command to reset M-508. You should
only use this function if the software reboot does not function
properly.
