Overview:
While many industrial computers currently available on the market are primarily equipped with serial bus interfaces like RS232, RS485, and RS422, the expanding range of industrial applications demands more versatile bus standards. Through market research, it's evident that there's a growing demand for the CAN bus interface. In addressing this demand, we'll discuss how to implement this bus standard on industrial computers that lack native support for CAN.
Applicable Models:
- K4 Series
- 05B-i5-5500U
- H4 Series
Prerequisites:
- MPCIE to CAN card (supporting 2 channels of CAN bus)
- 2 DB-9pin serial ports with 3-wire configuration
- Motherboard featuring a built-in MPCIE full-height slot
- Detachable serial ports on the chassis
Specifications of the MPCIE to CAN card: [Provide the specifications of the MPCIE to CAN card]
Perfect Compatibility with Industrial Computers:
- Utilizes standard MiniPCIe interface
- Communication with industrial computers via USB 2.0 pins within the MiniPCIe interface
- Powered by 3.3V via the MiniPCIe interface, with a power consumption of 200mA
CAN Interface Features:
- 2-channel isolated CAN interface
- CAN bus voltage and resistance: CAN-H, CAN-L voltage at 2.5V, with a resistance of 120Ω for both CAN-H and CAN-L
- Supports both CAN 2.0A and CAN 2.0B protocols, compliant with ISO/DIS11898-1/2 standards
- Programmable CAN baud rate, ranging from 10Kbps to 1Mbps
- Maximum data flow rate: Up to 20,000 frames per second for a single channel (at 1M baud rate, standard remote frame)
Isolation and EMC:
- Signal isolation and DC/DC power isolation for CAN channels, with an isolation voltage of 3000VDC
- EMC level for CAN interface: Contact discharge ±4KV, air discharge ±1KV
Operating System Compatibility:
- Supports Windows XP, Windows 7 to Windows 11, as well as Linux operating systems
Installation:
- Fits into standard MiniPCIe card slots, compact size for plug-and-play installation
Operating Conditions:
- Operating temperature range from -40°C to 85°C
Dimensions:
- Standard MiniPCIe board size: 30mm (width) * 51mm (length)
I. Hardware Installation (Using H4 as an Example):
1-1. Power off the system and remove unnecessary COM connection cables from the motherboard. In this case, remove COM4 and COM6 cables for installing the CAN ports.
1-2. Insert the MPCIE to CAN card into the motherboard's MPCIE slot and secure it with screws.
1-3. Fix CAN1 to the COM6 port on the chassis and CAN2 to the COM4 port on the chassis.
II. CAN Pin Definitions:
2-1. Considering the hardware installation location, it can be inferred that COM6 has been converted to CAN 1. The CAN bus follows a 3-wire DB9pin type configuration. Pin 2 is defined as CAN_L, pin 3 as GND, and pin 7 as CAN_H. Please connect external devices according to the pin definitions.
2-2. Considering the hardware installation location, it can be inferred that COM4 has been converted to CAN 2. The CAN bus follows a 3-wire DB9pin type configuration. Pin 2 is defined as CAN_L, pin 3 as GND, and pin 7 as CAN_H. Please connect external devices according to the pin definitions.
III. Driver Installation (Using Windows 11 as an Example):
3-1. Driver Download:
Download link: Link
Extraction code: HYSZ
Usually, only the USB driver installation tool Setup (V1.40).exe driver needs to be downloaded.
3-2. Right-click on the Windows Start menu and navigate to Device Manager. Check if the module model is recognized. If "Chuangxin Tech USBCAN/CANalyst-II" is detected, it indicates that the module installation is successful.
3-2. Right-click on the "USB driver installation tool Setup (V1.40).exe" file, then select "Run as administrator." There will be three plugins. Simply click "Next" to install them one by one in sequence.
With this, the driver installation is complete. You can now proceed to Device Manager to verify if the drivers have been installed successfully. If you see "Custorm USB Devices > WinUSB Device" recognized, it indicates that the installation was successful.
