LED indication
The dS1242 provides a red LED mounted immediately next to each relay to indicate whether it
is in a powered state (LED on), there are also two LED's mounted in the Ethernet connector
which will flash with Ethernet traffic. A row of three LEDs, Blue, Green and Red, are available
to the user for status indication. The Red LED lights when the module is in bootloader mode –
this is when the IDE is uploading system firmware to the module. The Green LED lights the
board begins running user programs. The three user LEDs are available and can be controlled
as digitalports 33-35.
