Additional diagnostics
(1) :
This display flashes for 6 x 100 ms if an incorrect character has been received.
This short flashing is repeated after a period of five seconds if an incorrect character is received.
This only occurs if the communication card has a communication fault (no message received for 10 s).
If the card never changes to normal operation, this display indicates that the wiring is definitely correct but that the configuration is not suitable (speed or format).
