LED indicators
The functions of the LEDs on the print (green and orange) depend on the firmware. Refer to
the OC32 firmware manual for the latest details. Standard function can be changed by
configuration by the user.
With firmware 3.0.0 the standard functions are:
Starting up:
•
Orange: is lit during the starting sequence of the OC32 (if the power is switched on).
This takes about 0.25 to 0.5 seconds
Normal operation:
•
Green: Flashes regularly 1 second intermittent to show that the module is active and
the processor is operating normally;
•
Orange: Flashes shortly when the OC32 receives a correctly addressed message
(Rs232, RS485 or DCC).
Bootloader:
When the bootloader is active (see firmware manual) both LEDs are lit continuously.
