6.3 The Same CAN-ID Conflict Issue
If the same CAN-ID conflict condition in CAN bus network
happened frequently, it may cause CAN bus communication failed in
I-7565-H1/H2 module. Users should solve the CAN-ID conflict
condition and reset I-7565-H1/H2 module for the later CAN bus
communication.
6.4 The PC Rebooting Issue
If users use I-7565-H1/H2 module for a while, the PC reboots
automatically. Please update the newest “Service Pack of Windows”
to your PC platform. For example, if users use Windows XP, please
update the service pack to SP3 or newer version to solve this
problem.
6.5 The Max Data Transfer Rate (fps) Issue
The max CAN bus data transfer rate in I-7565-H1/H2 is up to 3000
fps and it can be adjusted by I-7565-H1/H2 Utility. If users’ PC
performance is not good enough, the data loss condition may happen.
In this time, users can use “Advanced Config” function to adjust
hardware transfer rate of “CAN to USB” in I-7565-H1/H2 and it may
improve the data loss problem. Remember that hardware data
transfer rate can not be lower than the current CAN bus flow, or the
data loss will happen in I-7565-H1/H2 module.
6.6 The Data Loss Issue
There are two possible causes for the data loss problem. They are
described as follows:
(1) Software receiving buffer provided by API library overflow.
It means that the users’ program could not receive the CAN
messages from software buffer in time. Therefore, users should
optimize the communication strategy.
(2) Hardware receiving buffer overflow.
A large delay of the interrupt happened in the receiving-end PC
and it can be solved by enhancing the PC hardware performance
