You should only use this function if the software does not function properly.

Power LED

The Power LED will show solid green if power is properly applied

Ready LED

The Ready LED will show solid green if Matrix 514 complete system boot up. If Ready LED is off during system boot up, please check if power input is correct.

Turn off the power and restart Matrix 514 again. If

Ready LED is still off, please contact the manufacture for technical support.

Link/Act

When Ethernet ports are connected to the network,

Link/Act will show solid green and if there is traffic is 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.

Ethernet Port

Serial Console Port:

Serial console port share the connector with Serial port 3 but the pin definition as shown as follow:

P3

The serial console port is disabled as factory default setting.

To enable the serial console, you need to use the serial console cable and connect it to port 3. Use any terminal software such as hyper terminal and setting as follow:

Baud Rate: 115200

Data bits: 8

Parity: N

Stop bit: 1

Terminal type: ANSI

Once system is power on, you will see “Starting Matrix520….”,

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)”

Network Settings

To configure the IP address, Netmask and Gateway setting, please modify /disk/etc/rc as following: ifconfig eth0 192.168.2.127 netmask 255.255.255.0

For DHCP setting: dhcpcd eth1 &

For Ad-Hoc mode mode XXXX is the Matrix 500 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

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

6. rtc: Real Time Clock

7. gpio: General Purpose digital I/O

8. ttyACM0 and ttyACM1: USB Modem (CDC compliant)

File System

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 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 !!!

Utility Software:

Matrix 514 includes busybox utility collection and Artila utility software as follow:

Artila Utility Software:

The introduction of Artila utility software as follow:

1. update : update loader, kernel or root file system image.

Also use update —FORMAT to format user disk. Type

update—help to find the command usage

3. gpioctl: gpioctl is used to control the programmable digital I/O port located on the DB25 connector. Following example is to configure DIO1 as digital input and DIO2 as digital output with low output state.

Note: Update can only operated under supervisor mode

(password : root)

2. setuart: configure serial port setting. An example show as followed to configure port 1 as RS-485 interface with baud rate

921600. Please note only port 1 support 9-bit data at RS-485

How to make more utility software

You might also find utility software available on Artila CD under /Matrix & iPAC/utility such as ntpclient, ssh, scp, bluez and ssh-keygen. If you want, you can ftp or copy the utility software to Matrix 514 user disk (/disk). Also you can use find the source code and use the GNU Tool Chain to make the utility by yourself.

Mounting External Storage Memory

To find out the device name of the external memory device which plug into Matrix 514, you can use the command

/dmesg | grep sd or

/dmesg | grep mmc

Type

mount /dev/sda1 to mount the USB disk and

mount /dev/mmc0 to mount SD card

Welcome Message

To modify the welcome message, user can use text edit to modify the /etc/motd.

Web Page Directory

The web pages are placed at /home/httpd and the boa.conf contains the boa web server settings. The home page name should be index.html

Adjust the system time

To adjust the RTC time, you can follow the command

/date MMDDhhmmYYYY where

MM=Month (01~12)

DD=Date (01~31) hh=Hour mm=minutes

YYYY= Year

/hwclock –w

To write the date information to RTC

User can also use NTP client utility in Artila CD to adjust the

RTC time.

/ntpclient [time server ip]

SSH Console

Matrix 514 support SSH. If you use Linux computer, you can use SSH command to login Matrix 514. The configuration of

SSH and key are located at

/etc/config/ssh

The key generation program is available at Artila CD

/matrix & iPAC/utility/ssh_keygen

User can copy this program to Matrix 514 to generate the key

Install GNU Tool Chain

Find a PC with Linux 2.6.X Kernel installed and login as a root user then copy the arm-linux-3.3.2.tar.gz to root directory of

PC. Under root directory, type following command to install the

Matrix 520 Tool Chain

#tar zxvf arm-linux-3.3.2.tar.gz

Getting started the Hello program

There are many example programs in Artila CD. To compile the sample you can use the Make file to and type make

To compile and link the library. Once done, use ftp command ftp 192.168.2.127

And bin command to set transfer mode to binary

ftp>bin to transfer the execution file to Matrix 520 user disk (/disk) and use chmod +x file.o

Change it to execution mode and

./file.o to run the file

Daisy Chain connection

All the Ethernet ports of Matrix-514 can be configured as a Bridge. The Bridge combines one or more Ethernet interface and bridging them under a single bridge interface. Therefore

Matrix-514 can use two Ethernet ports as a bridge and make a daisy chain connection in the net work.

Using Daisy Chain connection, user can extend the network without using switch as follow

To configure bridge function, please use command brctl as follow:

/brctl addbr br0

/ifconfig eth1 0.0.0.0

/ifconfig eth2 0.0.0.0

/brctl addif br0 eth1

/brctl addif br0 eth2

/ifconfig br0 192.168.3.127 up
