LED Indication

The I-7565 provides the Converter function between the USB port
and the CAN port. It can handle both an 11-bit and 29-bit ID format
according to whether it is a CAN 2.0A or 2.0B. In order to provide high
performance when converting data, the I-7565 has built in software FIFO
queues, which include 1000 CAN data frames. It also provides two LEDs
to indicate to users what situation the I-7565 is in. The RUN LED indicator
establishes the power and operation situation simultaneously. If the
module is working in the operation mode, the RUN LED is always turned
on. However, when the module is working in the configuration mode, the
RUN LED will flash approximately once per second. The ERR LED is
used for demonstrating an error that has occurred. That is, the ERR LED
is normally turned off when the module works in a good condition. On the
other hand, when the BUS OFF error indicator of the CAN controller has
been alerted, the ERR LED will turn on. In this case, users can only
reboot the I-7565 module in order to turn off the ERR LED. If the
CAN/USB FIFO overflows, the ERR LED will also be turned on.
Furthermore, If users want to check what the error situation is they must
send the command string "S[CHK]<CR>". Depending on the result, users
will need to either reboot the I-7565 or use the command string
"C[CHK]<CR>" to clear the FIFO flag, which will then turn off the ERR
LED.
