Nowadays, Linux has been adopted widely by many users because of the properties of stability, open source, and free of charge. In the mean while, owing to the great supports from more and more companies and the mature development, Linux is now becoming one of the most popular OS on the market. Furthermore the hardware requirements of Linux OS in embedded system is not high, just only 386 CPU or better and 8 MB RAM. Therefore, besides Win CE of Microsoft, Linux has been already become another good choice in embedded OS.

The LinPAC-9000 is new generation Linux-based PAC from ICP DAS and is equipped with a powerful CPU module running a Linux kernel 3.x/4.x operating system, various communication interfaces (VGA, USB, Ethernet and RS-232/485) and slots for both high performance parallel bus type (high profile I-9K series) and serial bus type (high profile I-97K series) I/O modules.

Compared with the first generation LinPAC-9000, not only is the CPU performance improved have been added (from 1 GHz to 1.97 GHz) and support Linux kernel 3.x/4.x, but many reliability features, such as dual LAN, redundant power input, and dual battery backup SRAM, etc., making the LinPAC-9000 one of the most powerful systems available.

● Remote Maintenance via SFTP/FTP Server and SSH/Telnet Software
The SFTP/FTP server is used for uploading applications or downloading data. And SSH/Telnet is designed for managing the LinPAC-9000. By using the FTP server and SSH/Telnet, you can update and manage the LP-9000 remotely via the Ethernet.

ICP DAS provides the library file － libi8k.a which includes all the functions of the I-7000/9000/97k series modules. Users just install LinPAC SDK in Windows PC, the cygwin environment will be established automatically and users can develop LinPAC-9000 applications easily by GNU C Language. Apart from that, users can also use Java to develop LinPAC applications as well.

Note: Cygwin is a Linux-like environment for Windows.

● Built-in VGA Port
A built-in VGA port can be directly connected to a regular LCD display. Users can operate the HMI or SCADA software (running on the LinPAC-9000) with display, keyboard and mouse just as how they usually did on regular PCs.

● 64-bit Hardware Serial Number
The 64-bit hardware serial number is unique and individual. Every serial number of LinPAC-9000 is different. Users can add a checking mechanism to their AP to prevent software from pirating.

● Dual Watchdog Timer
A system could be hanged up when the OS or the AP fails. There are two watchdogs (OS watchdog and AP watchdog) designed to automatically reset the CPU when the situations happen. The design will increase the reliability of the system.

● Dual Ethernet Ports
LinPAC-9000 provides two Ethernet ports. The two Ethernet ports can be used to implement redundant Ethernet communication and separate Ethernet communication (one for global Internet, one for private Ethernet).

● Rugged RJ-45 connector for LAN1
The LP-9000 is equipped with a rugged and dustproof RJ-45 connector on the LAN1 port that is able to provide protection against both liquid and dust contaminants in harsh industrial environments, as well as protection against vibration and shock.



● Metal Enclosures
Superior resistance to the weather and external interference. Easier grounding and better static protection.

● Redundant Power Inputs
To prevent the LinPAC-9000 from failing by the power loss, the power module is designed with two inputs. The LinPAC-9000 can keep working even one power input fails, and mean while there is a relay output for informing the power failure.

● Ventilated Housing Design Allows Operation Between -25°C ~ +75°C
Each LinPAC-9000 is housed in a plastic-based box with a column-like ventilator that can help to cool the working environment inside the box and allow the LinPAC-9000 operating between -25°C and +75°C.
