6. Troubleshooting

If the Error response function on the I-7565 module is set to be
"Yes"(that means enable) via the I-7565 Utility during the configuration
period, the I-7565 will send the error code to the host PC through the USB
media when the I-7565 produces an error message automatically during
the operation mode. The meanings of these error codes are given below:
Error
Description
code
1 Invalid header
2 Invalid length
3 Invalid checksum
5 Timeout
If the I-7565 CAN baud rate is not the same as the CAN baud rate on
the CAN network, the data flow LED on the I-7565 will be flash with a
constant frequency because the I-7565 cannot send any CAN messages
to the CAN network. Therefore, users will need to read the I-7565 status
by using the command "S[CHK]<CR>"(in the section 5.5) to help users
understand what is going in the module. In general, the following errors
could occur: CAN media connection problem, terminal resistor problem,
different baud rate configuration with CAN network and the like.

Table 12: Error code table
The USB command string header is not
"t","T","e","E","S","C","P00E300", "P1" nor "RA".
The data byte of the CAN Message does not match
the data length of the CAN Message. For example:
Error: t001512345<CR>
Right: t00150102030405<CR>
The checksum from the ommand string does not
matched with the checksum calculated by the I-7565.
For example:
Error: t0012112209<CR>
Right: t00121122FD<CR>
The ASCII command strings are sent incomplete.
For example:
Error: T0018
Right: T0018<CR>
