LED Indication
Except the I-7530A-MR, all of the CAN converters provide 2 LED
indicators. The ON LED is turned on when the module is running in
Operation mode. If the module is in Configuration mode, the ON LED is
flashed once per second. The ERR LED is used for indicating if the
module is going wrong or not. If there is no error happened, the ERR LED
is always turned off. If some error occurs, different CAN converters may
have different behavior of the ERR LED. When the ERR LED is turned on
or flashed, users can use the UART command string
“S[CHK]<CR>” to get
the details about the error. If the error is happened due to the overflow of
the CAN or RS-232 software FIFO, users can use the UART command
string
“C[CHK]<CR>” to clear the error, or users may need to reboot the
CAN converter for recovery.
The position and behavior of the LED indicators to the I-7530/I-7530T,
I-7530A, and I-7565 is as following figure.
