1. The ZLGCAN driver does not detect the PCIe-9140I communication card at the
time of installation.
A. The device is not installed. Please insert the device into the idle PCI-E slot.
B. The device is not inserted into the system PCI-E slot reliably. Please insert
the device into the PCI-E x1 slot again in this situation. There is another
possible reason is that the PCI-E slot itself has problem. At this point, try to
insert the device into another PCI-E slot until the system can detect the
device.
C. The motherboard has no available interrupt assigned to the device. In order
to ensure the PCI-E interrupt is available, please enter the BIOS to modify
configuration.
2. The board card and driver are installed correctly, however, the data can not been
sent.
A. Check whether the cable is connected correctly.
B. The cable or board card has problem. Please try other ports, cables or
another board card.
C. Check whether the terminal resistor is connected correctly.
D. If the self-transmitting/receiving mode is not used, please ensure there are
more than two nodes on the bus.
E. The API calling is not correct, please read the related API documents
carefully and refer to the example program.
3. How to deal with the situation that many system resources are taken up because
of multi-channel high-traffic transmission?
For non-intelligent communication card, the driver has many works to do, so
these cards are not recommended to use in the large amount of data
transmission of multiple channels at the same time. It is recommended that the
data traffic should not exceed 1000 frames per second when multiple channels
work simultaneously. The data traffic can be increased appropriately when the
computer performance is better. Since CAN baud rate itself is the major reason
for limiting frame traffic, the system resources will be greatly reduced in the case
of a lower baud rate. The CAN system design should ensure the bus occupancy
