Parity: N
Stop bit: 1
Terminal type: ANSI
Once system is power on, you will see “Starting Matrix514….”. Keep typing $$$$ to turn on the serial
console function. If the serial console is enabled, you will see “Console (ttyS0)” as follow. Repeat
this procedure will disable the serial console and Screen will show “Console (null)”.

For DHCP setting:
dhcpcd eth1 &
3.12 Wireless LAN Configuration
Matrix-514 supports wireless LAN by using USB WLAN adaptor which uses Ralink 2571 (rt73)
controller. Please refer to the website http://ralink.rapla.net for the supporting list of the USB WLAN
adaptor.
To configure the wireless LAN setting, please use command:
ifconfig wlan0 up
iwconfig wlan0 essid XXXX key YYYYYYYY mode MMMM
For infrastructure mode XXXX is the access point name and YYYYYYYY is the encryption key and
MMMM should be managed.

Matrix-514 User Guide
‧7‧
For Ad-Hoc mode mode XXXX is the Matrix-514 device name and YYYYYYYY is the encryption key
MMMM should be ad-hoc.
To configure the IP address use command
dhcpcd wlan0 &
or
ifconfig wlan0 192.168.2.127 netmask 255.255.255.0
3.13 File System
Matrix-514 configures the root file system as RAMDISK and the user disk (/disk) which includes /home
and /etc directory are configured as Flash Disk. To find out the file system information, please use
command /mount as show as above. In addition, use command /df to find out the disk space of the
disk. The RAMDISK uses 8MB memory space to store the root file system and the user disk is about
11MB for user’s program storage.
Therefore, user’s program and utility software must be saved in the user disk space (/disk). Files
saved to other directory will be loss after power off.
3.14 Devices List
The supported devices are shown at /dev directory. Following list are most popular ones:
1. ttyS0: serial console port
2. ttyS1 to ttyS4: serial port 1 to port 4
3. mmc to mmc2: SD memory card
4. sda to sde: USB flash disk
5. ttyUSB0 to ttyUSB1: USB RS-232 adaptor (fdti_sio.ko)
6. rtc: Real Time Clock
7. gpio: General Purpose digital I/O
8. ttyACM0 and ttyACM1: USB Modem (CDC compliant)
