4. LED Indication
There are three LEDs provided to indicate to users what situation the
I-7565-H1/H2 is in. The following is the illustration of these three LEDs
and the position of these three LEDs shows as Figure 4-1.
(1) PWR LED :
It is used to help users to check whether the I-7565-H1/H2 is standby.
If the module is working in “firmware operation” mode, the PWR LED is
always turned on. However, when the module is working in the “firmware
updating” mode, the PWR LED will flash approximately once per second.
(2) RUN LED :
It is used to show whether the I-7565-H1/H2 is transmitting/receiving
CAN messages. The RUN LED will flash whenever a CAN message is
sending or receiving. In I-7565-H2, the RUN LED is shared by CAN1 port
and CAN2 port.
(3) ERR LED :
It is used for demonstrating an error that has occurred. The ERR LED
is normally turned off when the module works in a good condition. When
the Bus-Off error happened, the ERR LED will always turn on until the
Bus-Off condition disappeared. If the CAN/USB buffer built in I-7565-
H1/H2 overflows or CAN message can’t be sent out successfully, then the
ERR LED will flash continuously. In I-7565-H2, the ERR LED is shared by
CAN1 port and CAN2 port.
