ALX-9000 Introduction
The ALX-9000 are Linux based PACs that combine computing, I/O, and operator interface into a single unit, and provide the perfect solution for integrating HMI, data acquisition and control in an individual PAC. It is equipped with an Intel E3950 CPU, 1/3/7 I/O expansion slots and a variety of connectives including dual Gigabit Ethernet, VGA , HDMI, USB port, RS-232 and RS-485 interface. Local I/O slots are available to use our e-9K, I-9K and I-97K series I/O modules and remote I/O expansions are available to use our Ethernet I/O modules and RS-485 I/O modules.
User's programs can be saved in external storage device, such as CFast Card or USB mass storage device. LinPAC SDK is provided for users to develop LinPAC I/O applications rapidly and easily when e-9K/I-7k/9k/97k series I/O modules are used in the LinPAC. Users can develop LinPAC applications by using GNU C Language. In the meanwhile, all kinds of servers and functions make the LinPAC more powerful and users will be able to operate LinPAC to achieve their own project smoothly.
Software Features
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 ALX-9000. By using the FTP server and SSH/Telnet, you can update and manage the ALX-9000 remotely via the Ethernet.Rich Software Solutions
ICP DAS provides the library file - libi8k.a which includes all the functions of the e-9K/I-7000/9000/97k series modules. Users just install LinPAC SDK and develop ALX-9000 applications easily by GNU C Language. Apart from that, users can also use Java to develop LinPAC applications as well.
Hardware Features
Powerful CPU Module
E3950 (1.6 ~ 2.0 GHz, 4C4T) / 8 GB SDRAM (DDR4)
Built-in VGA and HDMI Port
A built-in VGA and HDMI port can be directly connected to a regular display. Users can operate the HMI or SCADA software (running on the ALX-9000) with the 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 ALX-9000 PAC is different. Users can add a checking mechanism to their AP to prevent software from pirating.
Rich I/O Expansion Ability (RS-232/485, USB, Ethernet)
Besides the local I/O slots, ALX-9000 also provides several RS-232/RS-485/USB ports and two Ethernet ports to connect with serial/USB I/O and Ethernet I/O devices.

Dual Watchdog Timer
A system could be hanged up when the OS or the AP fails. There are two watchdogs (CPU watchdog and Backplane watchdog) designed to automatically reset the CPU/Backplane when the situations happen. The design will increase the reliability of the system.
Dual Ethernet Ports
ALX-9000 provides two Gigabit Ethernet ports. The two Ethernet ports can be used to implement redundant Ethernet communication and separate Ethernet communication (one for a global Internet, one for private Ethernet).
Rugged RJ-45 connector for LAN1
LAN1
The ALX-9000 is equipped with a rugged and dustproof RJ-45 connector on the LAN1 port that can protect against both liquid and dust contaminants in harsh industrial environments, as well as protection against vibration and shock.
LAN2
Screw-lockable RJ-45 connector on the LAN2 port and there are screw holes (spacing 20mm) on both sides of the RJ45 connector, you can lock the RJ45 cable connector with them, to reduce the risk of the Ethernet cable falling off due to vibration occurring. Meanwhile, you can also choose a general RJ45 cable connector for your needs.
Power/Communication spring clamp terminal connector
The spring clamp terminal block that is used for the Power/Communication connector in the ALX-9000 offers advantages including anti-vibration, stable clamping, and easier installation.
Metal Enclosure
The AXP-9000-IoT features a durable metal casing to provide high levels of impact resistance and flame resistance and higher protection on EMS or other electromagnetic noises.
Redundant Power Inputs
To prevent the ALX-9000 from failing by the power loss, the power module is designed with two inputs. The ALX-9000 can keep working even one power input fails, and meanwhile, there is a relay output for informing the power failure.
Fanless Design with Wide Operating Temperature Range
With the fanless design for embedded applications, the operating temperature range is -25°C to +60°C for the ALX-9000 series.
Heat Sink Design
Advanced CPU Heat Sink Design for ALX-9000 series

Improved storage disk performance
CFast cards used on ALX-9000 series replaces the CompactFlash(CF) card used on LX-9000 series since they support SATA III interface, enabling much faster write/read speeds.

Remote I/O Selection
Ethernet
The available Ethernet I/O devices are ET-7000, ET-7200, ET-87P4/8-MTCP and I-8KE4/8-MTCP. The PAC can access them in Modbus/TCP protocol. A nModbus.dll is provided for C#, VB.net programming.
RS-485
The PACs are equipped with the RS485 COM ports which enable the transmission rate up to a maximum of 115.2 Kbps. The medium for connection is a twisted-pair, multi-drop, 2-wire RS-485 network that can link I-7000, M-7000, RU-87Pn with high profile I-87K modules. To access M-7000, a nModbus.dll is provided for C#, VB.net programming. To access I-7000 and RU-87Pn with high profile I-87K modules, PACSDK is provided for C#, VB.net, VC and VB programming.
FRnet
FRnet is an innovative industrial field bus that has many special features, such as high-speed deterministic I/O control, real I/O synchronization capabilities, non-protocol communication, and easy programming. With a FRnet communication module (I-8172W), the PAC can link FRnet I/O modules to implement high-speed distributed I/O (FR-2000 series). To access I-8172W, a pac_i8172w.dll is provided for C#, VB.net, VC and VB programming.
CAN Bus
The Controller Area Network (CAN) is a serial communication way, which efficiently supports distributed real-time control with a very high level of security. It provides the error-processing mechanisms and concepts of message priority. These features can improve the network reliability and transmission efficiency. Furthermore, CAN supplies the multi-master capabilities, and is especially suited for networking“intelligent” devices as well as sensors and actuators within a system or a sub-system. With I-8123, I-8124, I-87120, the PAC is able to demonstrate every feature of CAN, CANopen, and DeviceNet.
