(1) Why the module's PWR LED flashes quickly:
If the I-7530A-MR 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 will flash one
per 100ms because the I-7530A-MR cannot send any CAN message to the
CAN bus network. Therefore, users need to read the I-7530A-MR 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",
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:
If users use I-7530A-MR to communicate with SJA1000 CAN devices
and CAN baud rate is user-defined CAN baud rate. Then in SJA1000 CAN
