6 1 Introduction 1. Introduction About the Product This manual describes how to install the Linux OS on our industrial computer products and provides information about the operational check results as well as the minimum configuration and packages required to run the Linux OS. Refer to it when building your system. Make sure you understand and agree with the cautions below before using this manual. Refer to the User s Manual for our industrial computer products specifications. Refer to Chapter 5: RAS Function Supplementary Information when using particular functions such as the RAS function on our industrial computer products.

7 1 Introduction Security Warning When connecting to the network, be aware of security-related problems. See the examples of Security measures below and set up the product properly along with the network devices. [Information security risks] - Unauthorized access from the outside through a network could cause the system halt, data damage, or exposure to malware *1. - Invaded and used as a stepping stone, a device might attack the others through networks. (a victim becomes an assailant) - Information might leak without realizing due to the connection to the network. - Secondary damages such as harmful rumors, liability in damages, social credibility fall, and opportunity loss are expected led by the troubles described above. *1 Malware (Malicious Software) is software that brings harm to a computer system and performs unintended operations. [Security measures - e.g.] - Do not keep using the default password. (Refer to the product manual for the password setting). - Set a strong password. Combined with upper and lowercase letters, and numbers so that it cannot be easily analogized by others. - Change the password periodically. - Disable unnecessary network services and functions. - Restrict access to the network with network devices. *2 - Restrict ports to be released on the network with network devices. - Create a closed network connection using such as dedicated network or VPN *3. *2 Inquire for setting procedure to manufacturers. *3 VPN (Virtual Private Network): a secured network that wards off unauthorized access by protecting the communication path with authentication and encryption. Unfortunately, there are no perfect ways to avert unauthorized access or close a security hole that are endlessly found day and night. Please understand that risks are always involved with the Internet connection, and we strongly recommend a user should constantly update information security measures. 2 BX-220 Ubuntu Desktop 64bit Operational Check Manual

Launch two console windows. Enter the following command in one of the consoles. After the command is input, port A listens for serial data. root@bx-220:~# cat /dev/ttys0 Enter the following command in the other console. The character string aiueo is sent from port B to port A. root@bx-220:~# echo aiueo > cat /dev/ttys1 If port A (listening port) successfully receives the data, the character string aiueo will be displayed on the console screen, as shown below. root@bx-220:~# cat /dev/ttys0 aiueo Serial Port C Communication (RS-422/485) This serial port is provided for the RAS function. Read Chapter 5: RAS Function Supplementary Information, and proceed with the RAS preparatory steps. The verification program performs a full-duplex transmission. Connect the self-loop communication serial cable. (Refer to Figure 4.3: RAS connection diagram) Launch a console window. Execute the command indicated below, and confirm that 10 bytes are sent and received. Refer to the Readme file for details about the serial sample. root@bx-220:~# apt-get install setserial root@bx-220:~# setserial /dev/ttys2 irq 4 root@bx-220:~#./serial 0 0x22 micon: Set rs485 status complete. cmd [0x93h], dat [0x3h], sta [0x6h] BX-220 Ubuntu Desktop 64bit Operational Check Manual 19

Special note: The interrupt configuration of the RS-422/485 communication port is IRQ7 (fixed) in the BIOS. The device cannot share interrupts. On the other hand, Linux initially sets IRQ7 to interrupt sharing with other devices. During RS-422/485 communication, interrupt may not occur when interrupt sharing is necessary, resulting in communication failure. In order to avoid this, reassign the IRQ assignment from 7 to BX-220 Ubuntu Desktop 64bit Operational Check Manual

Apply the rebuilt kernel package to the system. In order to enable the I2C device, add i2c-dev to the /etc/modules file, and restart the OS. Once the patch has been applied, execute the following commands, and confirm that the output is as the text in red. root@bx-220# i2cdetect l i2c-0 smbus SMBus I801 adapter at e000 SMBus adapter _ i2c-x X is an arbitrary I2C bus number. ======================================================= (linux source dir)\drivers\i2c\busses\i2c-i801.c ~~ static int i801_probe(struct pci_dev *dev, const struct pci_device_id *id) {...
