(1) Why the module's PWR LED flashes quickly:
If the I-7530A-MR-FD CAN baud rate is not the same as the CAN baud
rate of the CAN bus network, the PWR LED of the I-7530A-MR-FD will
flash one per 100ms because the I-7530A-MR-FD cannot send any CAN
message to the CAN bus network. Therefore, users need to read the I-
7530A-MR-FD status by using the command "S[CHK]<CR>"(in the section
4.5) to understand what is going on. In general, it may cause by the
following errors: CAN media connection problem, terminal resistor problem,
different baud rate configuration with CAN network and so forth.
(2) How to set the user-defined CAN baud rate:
If users want to use the user-defined CAN baud rate for I-7530A-MR-
FD", choose the "user-defined" item and key-in the user-defined CAN
baud rate value (for example: 83.333) in the Baud rate field of the Utility
tool as the following figure.

(3) The rule of user-defined CAN baud rate setting in the SJA1000 CAN
devices for communication compatible with I-7530A-MR-FD:
If users use I-7530A-MR-FD to communicate with SJA1000 CAN
devices and CAN baud rate is user-defined CAN baud rate. Then in
