LEDs |
|
- TXD LED
- This LED indicates 'transmit data'
- RXD LED
- This LED indicates 'receive data'
- RTS LED
- This LED indicates 'Request to send'
- CTS LED
- This LED indicates 'Clear to send'
- BUS LED 1
- Dark:
No power of node defect
- Blink one or more times then 2 s dark:
number of blinks indicates the software type
the Node waits for a start command
- Blink 500 ms on/off:
indicates a fault
- Continue:
application is active
- BUS LED 2
- Flashing 100 ms on every received message
- Flashing 500 ms every 2 s: attention command

The CAN bus
- On both ends of the cable a 120 Ohm terminator
must be connected.
- The length of the cable
depend on the baud rate.
- It is advisable to use
ferrite beads on both ends of the CAN bus cable to avoid HF disturbance.
