2.5.2 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.
